$today = getdate();

How is your date formatted in the database.
Compare that to the format returned by getdate(), then consider using
date('Y-m-d'). That's assuming your MySQL date is stored as -mm-dd.
Nonetheless, this should set you on the right road.
It would also have helped your diagnosis if you echoed your SQL statement.

Well, we don't really have any useful information. A couple of things:
1. Echo the error number and error message which PHP returns. Your die()
message masks the error.
2. Use phpinfo() to check that MySQL is enabled in PHP.
3. Check the synatx/parameters for mysql_connect() at
http://www.php.ca/mysql_connect
4. You could force a TVP/IP connection by replacing lacalhost with 127.0.0.1

Feel free to e-mail me off-list. Many thanks, Jeffrey Jeffrey, This is the web - the words web hosting service and sensitive corporate data do not belong in the same paragraph. I know you had security in there, but security is not the first concern of most hosting services. The first place this can break down is the server - you are usually one of scores of virtual hosts. A misconfiguration, and your files are are exposed. The second place is the database - usually one database engine hosts scores, if not hundreds of databases. If the database is not correctly configured, your data is exposed. If there is a real concern about security, your client should establish its own server and database, and engage appropriate security consultants to ensure that it is secure, and to do periodic audits checks to make certain it stays that way. Next step, would be a dedicated server at a company like Rackspace - I know they're not Australian, but it was the name that popped up in my mind. After that, a virtual machine within the computer, as hub.org, among others, provides. Shared hosting - not if security is important. Anything on the web is much more exposed than it is on a WAN or LAN. So, it doesn't matter much right now who you pick, work up some budget figures, go to your client, and find out just how important security is to them. Unfortunately it's frequently seen as more important after the breach, rather than before. Sorry for rabbiting on, and if this is all basic stuff which you have already discussed with your client, well maybe some reinforcement will help.

This is really a MySQL question, but check section 12 of the MySQL manual.
Here's the link for operator precedence
http://dev.mysql.com/doc/refman/4.1/en/operator-precedence.html
I'd run some simple tests, just on the OR to see how it behaves. I usually
have to make at least two passes on logical conditions to get them right.
Where is your EOF() coming from? If you are cascading the statements, use
mysql_num_rows() or just test for the value returned from mysql_query().

[PHP-DB] Data split: web local machine
I have to generate a comma-separated(CSV) file of amounts and credit card numbers for secure transmittal to the bank. The CSV file is read by a bank-endorsed program, encrypted and transmitted. Most of the billing information: amount, period date, name, billing number is stored on the web server. The billing number and credit card type and credit card number are stored locally, call it the cc_file. The local storage format has not been decided on, the client is leaning towards Excel, but is well aware of how easily data can be damaged or destroyed in a spreadsheet. The procedure I initially thought of, was generating a file on the web side, emailing it to the client, then merging it with the cc_file to generate the payment file for the bank. I foresee a very messy, and fragile, macro in Excel to generate the merge. Now I'm thinking more along the lines of having a local MySQL database. The web side file will be created using SELECT fields INTO OUTFILE filename, and that would be mailed to the client. That file would be imported into the local MySQL database. A script / function would then generate the payment file. This local app I would write in PHP, using the PHP-GTK toolkit. The other possibility would be to access the web database from the local app, fetch the data directly and generate the file. That would involve having two databases open at the same time, but should be ok - $db_local and $db_remote. Opinions and suggestions will be welcomed.

Thinking about it, if you're retrieving data, manipulating it during the fetch makes more sense than retrieving it, then manipulating it afterwards. Other than that, all you can do is run some tests - reformatting dates, or string replacements, are not operations which are among the primary functions of database engines. So there's no best practise, except to normalize your data, optimize your database, and use appropriate indexes. Most likely, processing differences are insignificant. In that case the best practice would be whatever results in clearer code, code you can come back to in six months and quickly grasp its sense.

(http://www.lbc4cc.org/04-05board.php) that is
displayed by a simple PHP script. That was fine last year, but now we
have some new officers and some new board members and I have no idea
how to change the script so that Officers and Members table is
presented officers first (Pres, Vice-pres, Sec and Treas) and then an
alpha listing of board members who are not officers.
The existing script looks like this:
?php
$sql = SELECT * FROM members;
$result=mysql_query($sql);
if (!$result) {
echo Could not successfully run query ($sql) from DB: .
mysql_error();
exit;
}
if (mysql_num_rows($result) == 0) {
echo No rows found, nothing to print so am exiting;
exit;
}
echo table cellspacing='0' border='1' cellpadding='2'
bgcolor='#CC' width='100%';
echo tr\n;
echo thOffice/td\n;
echo thName/td\n;
echo thAddress/td\n;
echo thPhones/td\n;
echo thChurch/td\n;
echo thEmail/td\n;
echo thTermbrEnds/td\n;
echo /tr\n;
while ( $row = mysql_fetch_array($result,MYSQL_ASSOC) )
{
echo tr\n;
if ($row['Office'] == ) {
echo tdnbsp;/td\n;
} else {
echo tdb{$row['Office']}/b/td\n;
}
echo td{$row['Name']}/td\n;
echo td{$row['Address']}/td\n;
echo td{$row['Phone']}/td\n;

echo tdnbsp;/td\n;
} else {
echo td{$row['Email']}/td\n;
}
echo td{$row['Term']}/td\n;
echo /tr\n;
}
echo /table\n;
?

I'd cheat and add a numeric field, let's call it num_rank, ranking the
offices in the order you want them displayed, e.g.
President 10
Vice-President 20
.
.
.
Board Member50
Board Member50
Board Member50
and change the query to
SELECT * from members order by num_rank, last_name
which would provide officers and board member in the order you want them,
automatically sorted by name.
Incidentally, why do you have a separate table for officers and directors?
Maybe the answer is because it was cheap and easy,
but is there a separate listing for all members who are not on the Board?
In that case, you would be better off with two tables:
1. Add a logical lBoardMbr field to your general list of members, and this
general list of members also has to have a unique primary key. MySQL will
do that for you with an autoincrement field, with a table type of MyISAM.
That table type ensures no re-use of deleted keys.
2. Your BoardMbr table then consists of fields like this:
nMbrId - primary key of the person in the general list
cOffice - text, President, Vice-President Board Member
etc.
num_rank - as discussed above
cTerm - text field describing term.
When a member becomes an officer you do four things:
a) set the lBoardMbr field to true in the general table
b) enter the member's primary key value in nMbrId field in
BoardMbr table
c) enter correct value cTerm in the same table
d) set the lBoardMbr field to false in the general members table
for those members who are leaving the board.
The query to select the officers and directors would then change to
SELECT general.nMbrdID as nGenId, BoardMbr.nMbrID as nBrdId, *
from general, BoardMbr
WHERE nGenID = nBrdID
AND lBoardMbr != 0
ORDER BY num_rank, last_name
Advantage? Data more closely approaches 3rd normal form, no redundancy, no
errors when retyping, etc.
Long answer - hope it's been helpful.
Regards - Miles Thompson
PS If this is pedantic, and you know how to do all this stuff, pls forgive.
PPS Note I've assumed you have first_name and last_name fields /mt
And when I was lying bed this morning, in that half-state between full
wakefulness and sleep, I thought,
WHY BOTHER WITH THE lBoardMbr FIELD? AN ENTRY AND LINK IN THE BoardMbr
TABLE IS ENOUGH!!!
Good example of why one should sleep on solutions.
Which changes the SELECT to
SELECT general.nMbrdID as nGenId, BoardMbr.nMbrID as nBrdId, *
from general, BoardMbr
WHERE nGenID = nBrdID
ORDER BY num_rank, last_name

Hopefully an easier to understand scenario:
I have a form with - example - 5 items listed, each item from the DB and you

both the ID and the data entered from a single field. Obviously I can't use
a hidden field for this so the data has to be tacked-on to the input field
somehow?
Any help would save my life :-)

You mean like this:
In the display area of the script, using the ubiquitous while $myrow =
mysql_fetch_array($result), sub_key being the SUBscriber_KEY :
print( 'input type=checkbox name=chkdelete[] value=' .
$myrow['sub_key'] . '');
// rest of record - name, etc., then repeat
and as I was using this for a bulk delete, up top in the processing section:
//
// Bulk Delete

if ($chkdelete $bulkdelete){
foreach ($chkdelete as $value){
$sql = delete from subscriber where sub_key = '$value';

Hi guys,

for($i=0; $i$numOfRows; $i++)
{
$tmpVehMdlCd = vehMdlCd[$i];
$vehMdlCd[$i] = $$tmpVehMdlCd;

Thanks sooo much!

Look to your data - why are you storing an array element name matched with
a vehicle line? The T100Value appears to be the key field, retrieve it and
build your array within your script.
Think hard about why we have relational databases -- you are tying a value
to a position with this structure. If ever something has to be inserted in
the middle everything that follows will be broken, or you will be driven
into v. peculiar constructs to solve a problem which could have been
avoided up front.
On the other hand, I know nothing about your data or your application, o
maybe I'm blowing smoke.

Re: [PHP-DB] Duplicate record
Do a seek on the fields which cannot be duplicated; if there's a hit reload the page with the appropriate error message, otherwise reload the page with a success message. Although I have not worked with AJAX, this would appear to be an excellent spot to use it. Silently check after focus has left the final field which must be unique, doing nothing if data is OK, putting up a flag if there was duplication. As for a unique ID for each record, i.e. one that autoincrements, that's almost always a good idea.

At 09:01 PM 5/1/2005, Chris wrote: Hi, I've got question on using LOCK TABLES with MySQL and PHP. I don't have a great understanding of LOCK TABLES, but I'll lay out my situation: I've got a table and a PHP function to rebuild several columns in this table. I need to read these columns from the database (all of them) and recalculate the proper values, then UPDATE the rows with the new values. So, two queries, a read query, then a write query. This is a recurisve function in PHP, so it can't be done in one MySQL query unfortunately. I need to keep the values of these columns from changing in-between the read and write queries. As I understand it this is exactly what a WRITE lock is for. Now, to my question. What does my PHP function see if it goes to lock a table, and fails? Does the query itself fail, requiring me to Loop+sleep my application until it doesn't? Or does mysqli_query() not return until it has successfully locked the table? If it's one of these, can I force it to act like the other? Another thing, This table could possibly get *huge* in the future, if so I would probably need to loop through the results of the read query and RUN the UPDATEs as soon as my PHP app knows it to save on memory usage. Thanks in advance, Chris Chris, So your user LOCKS the table and then power fails, browser crashes, someone else tries to run same function ... etc. MySQL is so fast on indexed queries, are you certain this is information that has to be calculated and stored, rather than fetched and displayed? Of course you've not described the data or the calculation, so my question may be out of line. Generally speaking, though, it's not a good idea to lock either rows or tables in Internet apps.

Re: [PHP-DB] Re: Handling database calculations with a php page
First of all, check the SELECT statement in your database documentation, because you do this within your select. It is important you that you inform yourself about this, because you will use it a lot. So this is not really a PHP question. The statement is written something like this: SELECT a.currency + b.currency + c. currency curr_total from a, b, c WHERE a.cust_id = b.cust_id AND b.cust_id = c.cust_id AND c.cust_id = '$customer_id'; (or cust_id and some kind of transaction identifier) ( Tables are named a, b and c for convenience. Those who prefer JOIN syntax would write it differently) Secondly, unless you are having problems with rounding errors or must preserve the state of an issued document, like an invoice or purchase order, why write to a 4th table? Your data is contained in a, b, and c, and queries are v. fast, so what advantage or benefit is derived from storing the results in d? If you must do it, then you use either an INSERT or UPDATE statement, with appropriate customer and transaction IDs to keep things straight. If you do not know how to use/write the PHP code to execute this, examine the mysql functions in the PHP docs and avail yourself of the numerous tutorials on the Web. Google for something like tutorial PHP MySQL. As much as possible, do the work within the database. Hope this is helpful.

Re: [PHP-DB] Database Design Recommendations
Eric, Your second approach is fine. It's denormalized, extensible, and can be manipulated using tools you put in place. You may want to consider groups as well, thus people belonging to a group could view/edit pages, that has the potential to save a lot of administrative scut work. A table of permissions will also be required so that the various codes used for differing levels of permission are consistent. Suggest that when a user logs in the appropriate permission levels etc. should be fetched and stored in a session to save on some trips to the server. This session data, creatively used, could mean that only the files/pages that user is authorized for will be displayed.

I'll be storing these permissions in a MySQL database. My first idea was a single field with the SET datatype. This allows for a user to have multiple permissions, but makes it hard for other employees to add permissions later, if they decide to restrict a previously open access page. (I should mention that I'm the only person here who knows how to adjust a table in MySQL, and I won't be around forever.) My other idea solved the previously mentioned problem. I could create a second table with employee permissions. It would have two fields, employee_id and permission. Every employee would have one row for every permission they had.

Re: [PHP-DB] which DB to use?

Re: [PHP-DB] Mass mail
Yes - we're doing 900 per night. It's a one page letter providing the day's headlines with a link to where subscribers can view it. Viewing is done through a Flash movie so as to provide as secure an environment as possible. But now we're digressing into digital rights management. Code itself is nothing special; fetch names and heads from the database, build the list of heads, then run down the returned set of names and email addresses, creating the To; portion of the header, then bung the whole thing into the mail() function. Set the appropriate field in the database with whateer mail() returns, same info name, email result of mail() is fed to a browser for user feedback. Whole thing takes about 4 min to run.

Re: [PHP-DB] Bug with assignment operator ( := )
Ross, That's correct. From the MyQL manual: Begin quote .. In a SELECT statement, each expression is evaluated only when sent to the client. This means that in a HAVING, GROUP BY, or ORDER BY clause, you cannot refer to an expression that involves variables that are set in the SELECT list. For example, the following statement will not work as expected: mysql SELECT (@aa:=id) AS a, (@aa+3) AS b FROM tbl_name HAVING b=5; The reference to b in the HAVING clause refers to an alias for an expression in the SELECT list that uses @aa. This does not work as expected: @aa will not contain the value of the current row, but the value of id from the previous selected row. The general rule is to never assign and use the same variable in the same statement. ... end quote There's more at http://dev.mysql.com/doc/mysql/en/Variables.html So why not: select *, (StkhistMonthqty06 + StkhistMonthqty07 + StkhistMonthqty08) as total . . rest of statement ... . and total 0 Regards - Miles Thompson At 10:10 PM 8/28/2004, Ross Honniball wrote: SQL Statement: select *,@xtotal := StkhistMonthqty06 + StkhistMonthqty07 + StkhistMonthqty08 as total from StkMast as sm inner join StkHist as sh using (STkCode) where (StkAuthor like 'keller%') and (sh.StkhistYear='2004') and (@xtotal0); Notice the use of @xtotal.

Thanks in advance. Hi Norma, you can achieve this in a much more comfortable and elegant way: Create an integer column named oca (stands for Optimistic Concurrency Control Attribute). When you load the data to show them in the editing form store the value in a hidden field or in the session (if you are using sessions). Then when you update the data use the following statement: UPDATE table SET column = '$value' ..., oca = oca + 1 WHERE user_id = $user_id AND oca = $value_from_hidden_field After performing the query check the affected rows. If there is one affected row the update was succesful. If there are no affected rows it means that someone else updated this row in the meantime (thereby incrementing oca) and you can show a message like: Since the start of your editing process someone else updated this record set. Please cancel and edit the record again. This way you will never lock out a record set forever like Miles wrote and the user will at least be able to open the record set and see all data - even if sometimes (should be very seldom) he has to cancel and start again.

Re: [PHP-DB] Re: Restrict account access to single user
They are all good suggestions, Tim's is probably the most sophisticated, but it's inevitable that usernames and passwords will escape. On top of this I'd add a weekly count of user logins, so that the users in effect buy a given amount of accesses each week. If you're really serious, you will have to be somewhat brutal with your users - change the password, make it a difficult to remember combination, and do it often enough that they know you mean business. We've been fighting with this for four years, and there's no perfect solution. If it's a site where you are distributing published materials (.pdf's) you may take a good look at what Adobe calls, or used to call, Web Merchant, bite the bullet on the licensing and royalty fees, and reconcile yourself to a Windows / IIS solution.

[PHP-DB] Re: [PHP] Best table structure
Tom,
For a start, this is off-topic, and you also cross-posted - please don't do so.
Have a look at this article:
http://dev.mysql.com/tech-resources/articles/intro-to-normalization.html
I prefer simpler tables, so I would use the structure you have suggested,
with the possible addition of a date field and a field to indicate the
source of the ranking.
With the proper use of indexes, the fetching of results is extremely fast;
you don't have to worry about table size. Figure out the questions you have
to ask of the information, and then decide what inputs you need to answer them.

Would I be better keeping this format and inserting multiple rows on each
submit, or to have one row for all 81 variables ($name, 20 x Position, 20 x
Artists, 20 x Titles, 20 x Labels.)
I know that the latter will be easier to query.
Also, without maintenance, the size of the table for the current method will
get extremely large. Will that affect server performance?
I am still a newbie, so plain explanations would be most appreciated.

I've not worked with SQL Server for sometime, but my dusty copy of SQL Server 6 Unleashed (SAMS) advises as follows on pp 186-187: ANSI-SQL provides the capability of addressing a set of rows individually, one row at a time, by a cursor. A cursor is a pointer that identifies a specific working row within a set. ... ... Before looking at how to use a cursor, you need to understand what cursors can do for your application. Most SQL operations are set operations: a where clause defines the set of rows to address and the rest of the statement provides definitive instructions on what to do with the rows. This NOTE follows: NOTE It's extremely difficult to come up with compelling examples ff cursor programming. The problem is that cursors introduce a fantastic performance problem ... and nearly always need to be avoided. Maybe cursor performance has been improved since then. I suppose the $result we refer to when processing the results of a MySQL query is a cursor as it is possible to reposition within it.

Re: [PHP-DB] Impact of MySQL Queries
Think of bandwidth as the volume of data returned by the web server to the browser, not machine cycles. MySQL will use machine cycles, but there's more to it than that. For fastest response the fields you are running the query against should be indexed. What pushes you to 20 queries per page? That seems a little excessive, as each of those is a hit to the database. Are the fields indexed? Are they cascading queries, the second depending on results returned by the first, the third upon the second, and so forth? Could you handle your returned result set by getting more data and grouping it? More information is needed to answer your question properly.

T-Base-100 network but I imagine it would be like watching paint dry in a

and ob_end_flush() and no help...
Thank for any help in advance.

Robin,
That's a huge option list. Just from the point of view of the user it is
too large. Is there any way you can pare it down?
MySQL will select those records really quickly, but then the HTML has to be
generated and the broser has to render the list. Try and rethink this if
you can.

Re: [PHP-DB] User defined function in a mysql query

Re: [PHP-DB] transaction locking
Aleks, Many programmers learned the hard way that the scheme you are proposing did not work when they went from a single user to a networked environment. You've not said what database you are using. If MySQL you can let it's autoincrement increase your key automatically, perhaps feed it back as confirmation of completion. Using this you will not get duplicates as the insert is unique per connection. Check the MySQL docs for the last insert id. Try this - it works and takes a load off your code. Alternately, if you want to use your own scheme, establish a lookup table with two fields: keyvalue and tablename. Write a function that with the table name as a parameter, locks the table, retrieves the keyvalue, adds one to it, updates and exits. You will have to test for locks, you may end up with gaps in your key numbers. If possible, let the database do the work for you.

Re: [PHP-DB] What happens when the database is down?
C'mon, think about it. Connect to the database at the top of your page - if you can't connect either error out and die, or branch to alternate output. As far as lack of error reporting is concerned, check and see what level of error reporting is set on the server; the manual has a helpful section on this as well as how to set up and configure .htacess if your ISP has all error reporting turned off. If you are running locally, you can adjust the level of error reporting. There are lots of examples in the PHP manual. Couple of things: I know PHP and Apache 2 are not a recommended combination on LInux, you may be better off with 1.3.x. Aren't you also running a beta or rc version of MySQL - stable is still 3.x, isn't it? You may have two alternate sources of breakage there.

Re: [PHP-DB] Undefined Index error when trying to insert data from a form into a db
1. Check the manual on use of $_POST and notch down your error reporting
level. As these vars have not been defined PHP is throwing an error.
2. While you are at it, and assuming that your variables are all received
correctly, why not simplify your sql?
insert into test_scores set field_one = '$field_one', field_two =
''$field_two ... and so forth. It makes debugging INFINITELY easier and
gives you more control.
3. Not related to your question at all, what's the type of your first
field? Does it allow NULL's? If so then default it to NULL. (Something
tugging at the back of my mind says that a NULL should not be assignable,
but that's another issue.)

Re: [PHP-DB] Accessing MySql using Flash while using PHP as the middleware
Adam made a good suggestion - but using LoadVars is better, and if you are
retrieving text it's easier to bring it back as an xml file, otherwise an
ampersand stops you cold. Here's my call to the login script to
authenticate users for a news site when the login button is clicked.
The varSender and varReceiver are recommended by Colin Moock to avoid
caching. His ActionScript for Flash MX The Definitive Guide, O'Reilly,
ISBN 0-596-00396-X is worth every penny. Also visit www.moock.org
Values in first_txt.text, last_txt.text, and pass_txt.text come from those
text boxes.
The variable host is retrieved from a settings.as file in the first frame
of the movie.
ckval is stored in a shared object so that subsequent logins are automatic.
autologin = true is the key which unlocks the rest of the movie
read is the frame where another script loads the day's news stories, also
stored in a MySQL database.
frame 7 is for login failed - when I added it I had no space to name it.
So, what does the php script return? Exactly this, with no leading space or
empty line, and on one line:
ValidLogin=trueckval=some32bitkeyiwonttypeout
(I was tearing my hair out - everything looked RIGHT, yet the movie kept
failing, dumbly. Then I realized there was a blank like ahead of the
returned values. Removed it and magic happened.)
Flash is alternately exasperating and wonderful.

Yes, I understand about PHP, and I would assume Ruby also executes on the server - thus you would have primarily one or the other generating the page.

Re: [PHP-DB] address info, forms, maintanance
Chip, Given that you have duplicate entries, then one field, or a combination of several fields, will probably be unique. Before adding a record execute a SELECT, using the values from the form against that combination. If the number of records returned is greater than 0, then execute an UPDATE query, otherwise an INSERT. Now, that information is so vague to be almost useless, for it begs a number of other questions, such as How many questions are end users allowed to ask? How are questions flagged for expiration or completion/solution? What kind of mix of questions do you allow? Cookies only store a bit of information on the user's browser.

Subject: [PHP-DB] newsletter optimization help needed
Hi there Everyone,
Below is some code I use to send a newsletter to clients subscribed on my
mailing list. The problem is I have over
9000+ email addresses in the DB and it takes around 30-45 minutes to
send them with the below code.
Can anyone see someway I can optimize it so it sends out the newsletter any
faster? I've probably gone about this system the long way, but it works - I
just need to find a way to make it faster :-(
Thanks everyone
All the best
Chris

Re: [PHP-DB] table relationship
Three tables seems wasteful, and could mean that you have to do three queries when looking for someone. Why not approach it this way. Users table - info on all users, regardless of category Levels table - sets different access levels, e.g. clients, staff, administrators User_levels table - assigns levels to user id's This would give you more long-term flexibility as you would only have to extend the levels table to add granularity of access or control levels. I'd also have a look at various network permission schemes, because there are subtleties that are not immediately apparent when working up an access scheme.

There's an alternate route, but I've used it only over a network, not across the internet. Create a keys table which has two fields - tablename and keyvalue.

What would that be like, something along the lines of update keys ( keyvalue), ( str( val(keyvalue) + ) ) where tablename = 'var_tablename' The val expression converts the existing keyvalue to a numeric which allows a numeric one to be added, returning that expression as a string. (Unless I have their functionality reversed, but I hope you get the idea.) With his you don't have to worry about the lock and the value will be appropriately updated.

Re: [PHP-DB] Adding Record to database
Matt,
Check a couple of things:
1. Do you have a primary key with unique id? You could be getting a key
violation.
2. Echo $query and confirm that it is as you expect.
3. Add code to trap for, or at least display any generated error.
4. Are you able to test this INSERT at the MySQL console?
If so, and it works, compare what works in 4. with what you have at 2.

Re: [PHP-DB] LEFT JOIN not working
For a start simplify the query, so that you are returning only one field until you get it right, say ads_displayrate.name. Second, echo the SQL statement so you can see what has been generated. Third, check the datatypes returned for YEAR(), MOTN() and DAYOFMONTH() functions in MySQL. As part of your diagnosis you may want to include the generated output from these functions so you see what they are returning.

Re: [PHP-DB] how to update a text BLOB in ODBC?
Jeff,
Check your SQL. Shouldn't
$sql = insert into note_tbl
(note) values ('${note}')
where pkey = '45';
be UPDATE where pkey = '45' ?
Or, do a delete where pkey = '45' followed by an insert. In that case check
the synatx of your insert 'cause it doesn't look correct.

but it's been 3 weeks now and i cannot seem to get this question answered,
and our project is waiting..
the question simply is: how to write a BLOB (sub-typwith ODBC in PHP?
fyi, it shouldn't make a difference, but i am using interbase 6.0 as the
back end, and the blob is SUB-TYPE 1 (text).
*reading* the blob is trivial with php Unified ODBC. I just use a normal
SQL select statement:
==
$sql = select note from note_tbl where pkey = '45';
# get result
$result = @odbc_exec($conn, $sql);
# assign values
if ( @odbc_fetch_into($result, $row)) {
$note = $row[0];
}
==
(where notes is the BLOB field). pretty simple.
however, when i try to *write* it back:
==
$sql = insert into note_tbl
(note) values ('${note}')
where pkey = '45';
$result = odbc_exec($conn, $sql);
==
i get an error message:
==
Invalid modify request. Conversion error from string BLOB
==
.. so apparently i cannot simply write the string back out to the BLOB.
(tho' IMHO if i can read in a SUB-TYPE 1 (text) BLOB that easily, then i
should be able to write it back out that easily).
apparently this is not just at the PHP Unified ODBC level.. if i run
easysoft's isql program at the command prompt and try to run the same
commands, while i don't get as specific an error message, it does return
an error:
==
SQL update notes_tbl set note = 'hello there' where pkey = '16784'
[ISQL]ERROR: Could not SQLExecute
SQL _
==
does anyone have some example code for how to do this (in PHP)?
i'd be most grateful..

Re: [PHP-DB] Having more than one id in the same field
I can't remember CD's 12 rules regarding relational databases, but a rough paraphrase of one of them is that you do not need to know anything about how data is stored to manipulate it, the database schema should provide all that information. Another one is that you never repeat information that can be broken out and stored in another table. You have to normalize your data, so in this case you would add a field, call it EventHost with fields PriKey EventId RspOrg EventId is a foreign key, referencing the field in the Event table which identifies the event, and RspOrg is a foreign key which references the key values in the, lets call it Organization (or Host) table. (PriKey is the primary key for the table, a field which hard experience has convinced me to have in all database tables, though in this case it may not be needed.) Indexes on these fields will assure that your queries will be optimized and you won't be condemned to sequential reads of the database while fields are evaluated by expressions like ...where '$id' in (events.ids)... . The Event table no longer needs a RspOrg field, and you can determine additional information about the host organization or the event through this table. You may also add fields such as HostLevel which indicates whether the RspOrg is a primary or secondary host, and so forth. It's time to Google for a primer on SQL databases and normalization, work through a couple, and to ask yourself what kind of questions you will be asking of your database.

Among the other fields there must be a field that holds the 'responsible organization' of the event. This organization of course will be responsible for other events as well so I have to create another table that holds the organizations (id, name, phones, director etc) and then just pull the organization id to the events table. The problem is that it happens too often to have 2 organizations responsible for the same event so I'll have to add them both to the events table in the same record. How do you advice me to do that? I thought that I could use a text field to hold the ids and then when searching the database just change the MySQL command from ...where events.id='$id'... (As it would be if only one id was going to be used) to ...where '$id' in (events.ids)... or maybe something using LIKE. Do you think it can be done this way? Apart from the responsible organization I may have other fields in the same table having the same problem (for example: the event visitors are staying in one hotel and I want to hold control of the hotels as well. Maybe 2 hotels are used instead of one). If I solve my problem this way, do you think that it will be too difficult or 'heavy' to have more than one condition like this in my queries?

An awful lot of db work can be done w/o express locking of records. You get an implicit lock on an UPDATE or INSERT. I've not checked the MySLQ docs, but the classic way to see if a record is locked is to attempt a lock.

Re: [PHP-DB] advise needed for 'authorized only' site
At the top of every page ...

PHP_AUTH_PW ] !=grail ) { if( !session_is_registered( member_id ) ) {

The lancelot and grail were used only so that ht:dig could index the
site, so they can be chopped out. The member_id flag was set in
user_logon2.php.
User_logon2.php was a little more complex. The goal was to allow only one
user in from one browser on one machine, thus a series of checks was
followed ...
1. If there was no cookie, then a regular login was displayed
2. If there was a cookie, its value was checked against the database, and
if everything was OK (user wasn't blocked, etc.) then member_id was set.
Member_id was only a semaphore and contained no value.
3. If there was a cookie, but it didn't validate correctly, access was
denied and the user was asked to contact the office.
4. If there was no cookie, but the login values (user/pass) showed that one
had been set from another machine or browser, access was denied and a
message displayed to that effect, again with an invitation to contact the
office.
If I remember correctly, the origin var was set so that after the login
check a valid user was returned to that page.
All this complexity was an attempt to solve a bad pass-around problem for a
daily business newsletter. Yes it was very restrictive, but that one line,
at the top, protected every page so no one could blast in from Google, etc.
In the same way, it let the owners of the site do their editing in Front
Page, and everything was OK, so long as they didn't touch it.
How did we use it? An email was sent each day to subscribers with an
embedded link to the current day's news page. If the above check passed,
then the newsletter, a PDF file, began downloading to their browser. Yes,
IE 5.5 gave us a BUNCH of trouble, but that's another issue. When it
worked, it was seamless - all the subscriber got was the news, which if
they then wanted to pass around they had to save, write up an email and
attach the pdf. A little more bother than simply forwarding a pdf sent to
them directly.

and see if they already have logged in and if they have not then trigger the

Not sure exactly how to implement but I've read on the practice before.

Subject: [PHP-DB] advise needed for 'authorized only' site
I have set up a section of my company site for use by authorized dealers
only. I am currently using
mysql authorization, which works for the first page, but if someone were
to
type in the url of an
underlying page they would be able to get in without authorization. I know
I could use .htaccess
for handling this but with a minimum of 350 -400 users to keep track of
that would be unwieldly to
say the least, especially for my boss who doesn't have a clue about *nix
and has never even heard
of .htaccess.
What other options do I have to keep the underlying pages from being
accessed without the user
being forced to go through the logon screen?
Thanks,

Re: [PHP-DB] extracting unique entries from mysql dbase
What you want to do is common, everyday stuff. There are lots of examples.
There's a fine manual at www.php.net, fully commented. If you have a look
at mysql_query() I believe there is an example in
the explanatory text / comments on how to use the returned results.
There are also lots of tutorials and examples, key words would be php,
database web site.
And, as always, Juli Meloni's www.thickbook.com, which has some really
well-developed tutorials.
Hope this points you in the right direction - Miles Thompson

Hi everyone,
I have a mysql row similar to the list below. What I need to do is have php
output a link list from this.
I'm new to php but in my head I picture something like:
?
foreach unique entry in $row_links['dbase'] {
echo a href=$PHP_SELF?catagory=Wind Chimes - Classic Hand-Tuned
Collection - SongbirdsLINK TEXT/a;
}
?
The links will be on the same page thus the $php_self. The script will take
a GET variable called category to display the proper items from the dbase.
It's the foreach statment or whatever it should be that I need a bit of help
with.
Any ideas would be greatly appreciated!
Thanks,
Tim

Re: [PHP-DB] extracting unique entries from mysql dbase
Tim,
In your query use SELECT DISTINCT, rather than SELECT. That way you will
not get duplicates returned from the database.

Re: [PHP-DB] Need help getting record number off insert
Check the DataFlex docs and see if it has a function that returns this information, or if the ODBC driver has such a function. Record numbers are dangerously useless in most database operations - they get re-used and changed when records are deleted or repair/compress functions are executed. I hope you aren't planning to use this as foreign key, i.e. for referencing information in this table from another table.

It's a DataFlex database and the driver i'm using is by Connex. I know that you can somehow insert a SQL statment inside an other statement. I was thinking if I could quesry the record inside the insert, then I could get the record number. I'm not sure how to do this though. I was also thinking that I might be able to get some info from the resourse identifier that is returned to PHP, but I don't know how to read it from an insert, odbc_result doesn't work. Anyone have any clue how I can do this? I'm kinda new to this, so please help me out. I'm running IIS/Win2k, PHP 4.2.1 using ODBC through Connex DataFlex driver 8.7.

Re: [PHP-DB] POSTGRESQL PHP
1. run a script containing phpinfo() function and confirm you have support for pgsql 2. add code to display the error message generated by either php or pgsql when you try to connnect 3. (Maybe this should have been first) I don't know about Windows systems, but on *nix, PostgreSQL has to be started with the -i switch to be accessible from the Internet. Check docs. Hope this helps - Miles Thompson PS For help on the list #2 suggestion is really important. At 06:10 PM 9/9/2002 +0200, Tomator wrote: I've installed MySQL and PostgreSQL on my XP.
