Re: [PHP-DB] Newbie Question $2
Oh a few quick things. First, you can use substr to break up the phone instead of grabbing characters- might be a little easier to read long term. Secondly, mysql_real_escape_string will return the cleaned string, but doesn't change the original variable. So you'll need $phn = mysql_real_escape_string($phn); Thirdly anytime you use a single quote the strong is interpreted literally. You'll want to switch out the single quotes with double quotes, and then wrap $phn in single quotes in order to not break your query. "Select ... Where phn = '$phn'" I'd also really suggest looking at using PDO or even the mysqli extension tho instead of just plain mysql (believe this has been deprecated). Sorry for the quick reply, on mobile.

[PHP-DB] Configuring PHP with GD and JPEG support
Hello, Questions with regards to compiling PHP to support GD with JPEG on 64-bit CentOS 5.5. 1) Specifying folder for jpeg library When I execute the following command, am I saying the full path to libdir is at /usr/source/lib64? ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-gd --with-jpeg-dir=/usr/source --with-libdir=lib64 Should I have done the following instead? ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-gd --with-jpeg-dir=/usr/source/lib64 2) After copying the compiled JPEG libraries to the the lib64 directory, PHP is still unable to call the GD functions (ie ImageCreateFromJpeg) properly. Once I've done the following. ./configure --enable-shared make make install I have the following files installed. Meanwhile the /usr/local/lib64 directory doesn't have these files. Despite copying the whole set to /usr/local/lib64, the above configure command still doesn't work. /usr/local/lib/libjpeg.a /usr/local/lib/libjpeg.la /usr/local/lib/libjpeg.so -> libjpeg.so.8.0.2 /usr/local/lib/libjpeg.so.8 -> libjpeg.so.8.0.2 /usr/local/lib/libjpeg.so.8.0.2 The following displays a blank page on my Firefox.

So: SELECT count(*) AS `CountUniqueDatesInMyTbl`, date(solarAWDateTime) AS `uniqueDate`, 'aweber_7solar_aw' AS `tableAlias` FROM aweber_7solar_aw GROUP BY `uniqueDate`; That's how I'd write it, anyway.

You have 2 more opening parentheses than close parentheses in that SQL
-- in both cases, the parenthesis immediately preceding currval should
be omitted.
Also, to ameliorate your quote hell, you might consider using a heredoc

a union is what I want. and had tried that but using table names as the

a prototype like this now working but I've pretty much decided to go back
and redo the java program that parses the text files and builds the

Re: [PHP-DB] Building WHERE SQL clauses
Hi all thanks for the responses! What I have is a 6 table db that has each
table created from the output of 6 identical laboratory machines (chico,
harpo, ...). The out put is a text file which I import as a table named
after the machine. I do realize that one solution is to add the machine
name as a attribute and concatenate the tables together. I'm going to weigh
that change against Bastien's suggestion of UNIONing the selects.
I must admit that I'm still rather weak in the SQL department and did try a
solution of:
SELECT * FROM (chico UNION harpo) WHERE operator = "Bill" OR operator =
"Jessica" but that apparently is a SQL syntax error.
Thanks again for the insight and any other suggestions you might have. ---

[PHP-DB] Building WHERE SQL clauses
Hello all. I'm using PHP to build a query for a database that consists of multiple tables, all with identical attribues. A typical syntax try looks like this: SELECT * FROM chico, harpo WHERE operator = "Bill" OR operator = "Jessica" MySQL responds with this: Couldn't execute query.Column 'operator' in where clause is ambiguous I was hoping that since the tables are identical all I would need to do is list the attribute values not have to append them to the table names. Is there any way to do this? Perhaps with a setting in MySQL or a different syntax (JOIN, UNION, ...)? If not are there available some canned code snippets that build these types of strings from values passed in the $_POST array. Thanks for any insights on this. --- Mike -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It really feels like a command I may have used in the SQLite analyzer or
something. However, Im sure I copied it from an example script in a book. I
ve put holds on all the books on PHP and (My)SQL at the library and will check
them all.

To me newbies picked up PHP easily because "hey, this query string variable is $foo just like when I do a post variable of $foo!" and $_REQUEST to them is their way to get around a register_globals = off installation.

Yes, there could. But part of that would rely on a *very* motivated end-user (or we'll call them "hacker") - they would probably find a way in or do what they want either way. There's no reason to make it easier just because "well they can hack something up to do that anyway" - that's a Microsoft approach to security. Whatever happened to people at least trying to discourage abuse or issues. I have never used $_REQUEST and my applications don't seem to have any issues. Obviously someone could have tried to switch POST/GET on me, but I still ensure proper bounds checking/sanity checking/type checking/etc. But I would not allow someone to issue a GET variable to override a cookie value without having to make the extra effort (and furthermore understand how the variables work on the server side to make it actually work how they want.) > Use $_POST when you expect the data to always be in POST data. correct. > Use $_GET when you expect the data to alwasy be in GET data. correct. > If you actually want to accept HTTP requests of either kind for > flexibility to an external user, by all means use REQUEST.

This is probably the case. I have never needed to use trans_sid. It introduces some complexities that I don't think are needed. $_REQUEST is basically a new way of doing register_globals, which is a security issue. register_globals can allow a savvy user to overwrite a variable with another source - say you wanted a POST variable, a user could supply GET instead. or if you want it to come from a cookie using $_COOKIE it could be overridden using GET. If that makes sense. There's a lot of information about it. It was disabled by default a while back. Never enable it. You do not need it, period.

That's because you've got loads of implicit type conversions going on there, so
you're not comparing like with like.
For if ($foo) ... and if ($bar) ...:
within the context of the if(), both $foo and $bar are implicitly converted to
Boolean:
- (bool)0 is FALSE
- (bool)"any non-empty() string" is TRUE
On the other hand, for if ($foo==$bar) ...:
in the context of the == comparison, $bar is converted to a number, and any
string not beginning with a numeric character converts to numeric zero -- so
you get a comparison of zero with zero, which is, of course, TRUE!
Or, in other words, (bool)$foo!==(bool)$bar, BUT (int)$foo===(int)$bar
It's exactly when you *don't* want this kind of automatic type-conversion
shenanigans going on that you should use the === operator to make your intent
entirely clear -- otherwise you have to be extremely aware of the context in
which you are evaluating your variables in order to avoid hidden surprises like
this.
Cheers!

The absolute simplest way to do this is what you originally had.

[PHP-DB] Need Help Compiling PHP5 With MS SQL Support
I am new to Linux and have NEVER compiled PHP. I have PHP 5 and need to compile it with MS SQL support. Per PHP docs, I installed FreeTDS and tested it and it works. Now I need to (re)compile PHP to get the support I need to access MS SQL databases. I am on a Ubuntu 6.06 version of Linux. Again, PLEASE keep in mind that I am new to all of this. I tread VERY softly doing this! (I am on a VMWare virtual server and have made a clone drive as a backup.) Am I correct that my first step is to see what is already compiled into my version of PHP using php -m? I have that list. I assume that my next step is to get the PHP source for PHP 5.1.4. From here on I do not understand clearly by reading the docs I have searched for on the Internet through Google. Is there a place that has a VERY clear, step by step process to compile PHP? Any and all help is GREATLY appreciated. TIA. Mike -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That's what the SID constant is for. You can even use it with impunity when
cookies are in use, since it is set to the empty string in that case.

You don't need a strlen() call here, as substr understands "count from the
right" notation:
$sHTML = substr($sHTML, 0, -1);
... or, with Alex's correction:
$sHTML = substr($sHTML, 0, -2);

1. You have unquoted strings -- should be 'A' and 'Z'.
2. The test condition in your for is wrong (and either that or the break is
redundant).
Here's how I'd write it:
for ($j='A'; $j!='AA'; $j++):
echo "| $j |";
endfor;

mysql_fetch_array() only fetches one record of the result set at a time.
Thus, the code's doing what you told it to. The while() loop is what you
want. Why do you need to use a foreach() loop? At that point, there's
nothing to foreach() through. No array has been constructed.

Suppose you have a script that looks a bit like this (but hopefully with more input validation and error checking!): $value = addslashes($_POST['text']); // magic_quotes_gpc off $sql = "INSERT INTO tbl SET fld = '$value'"; database_execute($sql); Now suppose the user types this into the 'text' form field: Here's an apostrophe Here's what happens: PHP does this: $value is set to: Here\'s an apostrophe $sql becomes: INSERT INTO tbl SET fld = 'Here\'s an apostrophe' Which is sent to the database via database_execute() The DATABASE now does this: Receives the SQL statement: INSERT INTO tbl SET fld = 'Here\'s an apostrophe' (Note how the \ escape is required here to stop the field value from terminating prematurely -- but this escape is aimed at the *database*, and is not a PHP escape. A lot of confusion seems to arise here for databases which use the same \ escape character as PHP.) Extracts the value: Here\'s an apostrophe and de-escapes it to give:Here's an apostrophe Which gets inserted into the database. So the value inserted into the database is the unescaped original, and on retrieval there are no \ characters in the retrieved value to be stripslashes()ed.

That's not a good idea, as it would also match entries like:
391 247 48 172
39 147 148 172
395 347 1486 1172
etc.
I think you really need to find out exactly what's in those failing records,
and why it's not matching your query.

Because your query and echoes are within an "if" block, I'd say that
$submit is evaluating to FALSE, and thus not executing the query and
echoes.
Add (before the if statement):
echo "Submit = $submit";
Make sure that $submit is evaluating to TRUE.
To All Beginning Programmers ("Newbies"), or just people who want to
easily debug their code:
Try adding debugging statements to help you find problems. A few echoes
or prints in selected locations will help identify the issue. Make sure
your variables are evaluating to values that you think they should be.
If you want to keep the debugging statements in your code and just
activate them when you need to see them, do something like:
// near the top of your code
$debug=TRUE;
// and anywehere in your code
if ($debug) {
echo "DEBUG: Submit = $submit\n";
}
// or whatever echo might help you nail down the problem. Put as many of
these in your code and you can turm them ON and OFF very easily, by
changing one line of code.
OR for even quicker debugging, replace $debug=TRUE; with
$debug=$_GET['debug'];
and then you can turn it on in by adding ?debug=TRUE at the end of the
URL. Example: http://www.php.net/path/my.html?debug=TRUE
or: http://www.php.net/path/my.html?debug=1
**DISCLAIMER** Using the URL method is NOT a secure way to do this!!!
And I'm sure there's plenty of folks groaning out there because it is a
BIG security hole. You really would want to do this on a development
machine and network, and remove the debug code for production. That
really should go without saying.
Good luck.

Absolutely -- this is the Command-Line Interface. As this is intended for
command-line scripting, it has no notion of being used in a Web context and
does not even attempt to fill the $_POST or $_GET (or most of the other $_)
arrays. You need to use either the CGI SAPI, or the Apache module.

Is this a direct paste from your original? If so, there's an obvious error
here -- one of those should be $var2,'cos as it is you're never even echoing
the value of the $_GET parameter.

strtotime() is, unfortunately, a little American biased and only recognises
the mm/dd/ numeric format (using slashes). So the above is returning
the equivalent of the 11th day of the 30th month of 2004!
You can use other PHP functions, as has been suggested, but you might also
investigate the mySQL date formatting functions, as I believe they work
perfectly well on input dates as well as output ones.
Cheers!

And, by the way, why on earth are you using a print_r an a straight literal

Yes, but you didn't include the { } to indicate the scope of the if -- so it
terminated at the ?>.

Well, your taste seems to be to use { }, so :-endif is irrelevant.

Nothing wrong with having the closing ?> there -- please re-read my
response. If it's still unclear to you, please ask specific questions.

The closing ?> of a PHP segment also implies an end-of-statement semicolon
-- so the above is equivalent to:
if ($row_rsCS == false) ;
?>
Which, of course, means that the scope of the if doesn't extend to anything
beyond this point.
You need to mark the block controlled by the if, using either {-} or
:-endif, according to your taste.

Spot the difference: you have quoted the email value $v in the INSERT
(correct) but not in the SELECT (wrong). This means that:
$res = mysql_query( $sql ) ;
is failing with a SQL error, so $res is not being set to a valid MySQL
result resource, so that when you execute:
if (list($row) = mysql_fetch_array($res)) {
The mysql_fetch_array() complains with the error you have seen.
After any database operation, you should check for failure and echo out any
error message -- see mysql_errno() (http://php.net/mysql_errno) and
mysql_error() (http://php.net/mysql_error).

Another approach to this might be: Keep a column in your database table for time of last update of each record. When a user reads a record for update, don't lock it at this point, but save the time at which it was read into the user's session (or somewhere in the database). On receiving a potential update, check the time the record was read (as recorded above) and the last update time of the record (lock the record as part of this query) -- if the update time is later then the read time, someone else has updated in the interim and you should abandon ship; otherwise, update the record including a new last-updated value; in either case, unlock the record. This methodology keeps both the lock and unlock in the same script (and potentially within a single database transaction), so no need for any external checks for locked records, and minimizes the amount of time for which any one record is locked.

This may be true, and I will certainly be keeping an eye on the news to see what the result of the presidential election is. However, a substantial proportion of the people on this list do not have the right to vote in this election, and are extremely irritated to receive a reminder about voting on a list where such a reminder is wholly off-topic.

I think you're missing some tags -- these should be
present around each value extracted from the database, so:
while ($check=mysql_fetch_array($result)){
print
"{$check['LNAME']},{$check['FNAME']}({$check['CID']})\n";

RE: [PHP-DB] can i display an image _directly_ from postgres db storage?
Philip, Typically, it's infinitely more performance-friendly to simply store your files on the hard disk and use the database to refer to that location. For instance, assume your root web dir is /www. Inside there you have an /images directory. If you religiously put all files inside of /images you can store the file name inside the DB and simply have your code output the proper HTML. Or, if you have to actually do image processing, you can have your code query the DB and then read the file into an image handler for GD or whatever you're using to do the processing. Either way, it's usually encouraged not to store BLOBs whenever possible due to the performance hit that's usually associated with that. -M -Original Message- From: P.

[PHP-DB] SSL connection between PHP4 & PostgreSQL ???
Hi, I've setup a postgres server (7.4) and confirmed that SSL is enabled - I can successfully connect via tcp socket over SSL using the psql client. >From PHP4, how can I get the pg_connect function to negotiate an SSL connection? I gather from researching the issue that pg_connect uses the same libraries as psql, so that this should be possible. But I've tried every syntax I can think of... the "options" parameter to pg_connect is not well documented. I've played with all varieties of "requiressl" or "ssl", alone or as a boolean, e.g., "requiressl=true", etc... If not possible in PHP4, is it in PHP5? Any help greatly appreciated!

$Proj1 now contains a comma-separated list of the values passed to
$s_Industry, which was filled by the CCGetParam() above. The above code
block is equivalent to (and would be better coded as):
if (count($s_Industry) > 0 AND is_array($s_Industry)) {
$Proj1 = "'".implode("','", $s_Industry)."'";

Plug the value for $Proj1 built above into this, and again you have
something that may look very familiar to you. It's the very same IN clause
I was urging you to use yesterday! ;)
> if ($Proj2)
> $VendorJobs->ds->SQL.= " AND

So you now have a dynamically built portion of SQL, in $VendorJobs->ds->SQL,
that has a clause like "AND x IN ('a','b','c')" for each input field that
has any values set. According to your specs, this could be anywhere up to
six separate clauses. This seems to be exactly what you wanted, so your
code looks good to go.
To help you understand exactly what's going on here, or in any script or
program you're struggling to interpret, I would recommend two time-honoured
techniques:
(i) Dry running: get out your genuine old-fashioned pen and paper, pretend
you're the PHP interpreter processing this program, and write down the value
of each variable as you work through the code. Yes, it can be quite
long-winded and tedious, but you really get a tremendous feel for exactly
what's going on. The number of times I've done this and cursed myself as
I've watched a value going out of range, or not getting set at all, I
couldn't begin to count.
(ii) As a variation of the above, put *lots* of debugging echos in your
script: echo the value of every variable frequently and redundantly -- it
can help sometimes just to have the reassurance that a value really hasn't
changed, even though you know it absolutely shouldn't!! Again, if you're
struggling with how a script operates this can help you see how values are
built up, and can often show you exactly where a wrong value gets calculated
(and how, and maybe even why). It's especially important to echo your final
complete SQL statement just before it's executed, so that if it produces an
error message you've got the actual relevant SQL right in front of you.
Hope this helps.
Cheers!
Mike

Seems to me we've just answered a very similar question to this (and I'd be
surprised it there weren't several relevant threads in the list archives).
Nonetheless:
> $sql = "select ID from products where ";
>
> if ($webpage->parameter_isset("CategoryID")) {
Two possible approaches that spring to mind are:
$sql = "select ID from products where 1=1";
if ($webpage->parameter_isset("CategoryID")) {
$sql .= " AND CategoryID = '{$webpage->CategoryID}'";
}
if ($webpage->parameter_isset("CompanyID")) {
$sql .= " AND CompanyID = '{$webpage->CompanyID}'";
}
if ($webpage->parameter_isset("SettingID")) {
$sql .= " AND SettingID = '{$webpage->SettingID}'";
}
if ($webpage->parameter_isset("SystemID")) {
$sql .= "AND SystemID = '{$webpage->SystemID}'";
}
Or:
$where = ''
foreach (array('CategoryID', 'CompanyID', 'SettingID', 'SystemID')
as $field):
if ($webpage->parameter_isset($field)):
$where .= ($where?' AND':'')." $field = '{$webpage->$field}'";
endif;
endforeach;
if ($where):
$sql = "select ID from products where$where";
...
else:
// no where information -- major error
endif;
Cheers!

Your SQL is going to need some sort of conjunction here, as your WHERE phrase already
has an initial condition in it. I'm guessing you'll want an AND, so:
$sql .= 'AND ';

You've switched from $_POST['states'] to $_POST['state'] -- fix whichever is wrong ;)
> $sql .= "state='".implode("' OR state='",
> $_POST['state'])."'";
Given the conditions you want your WHERE phrase to test, you're going to need more
parentheses to force the ORs to be evaluated before the ANDs; this is where the IN
syntax, IMO, is more readable. So you want either:
$sql .= "(state='".implode("' OR state='",$_POST['state'])."')";
or:
$sql .= "state IN ('".implode("','",$_POST['state'])."')";

And throughout this second block you've used a cut'n'paste of the first block without
altering ['state'] to ['job'] -- just the sort of oversight that can give you the
raving heebie-jeebies somewhere down the line if you fail to fix it! ;)

Given the moderate complexity of this code, I'd strongly recommend echo-ing out $sql
immediately before it's used whilst you're in testing mode. When your query fails,
you'll already be one step ahead in working out what the problem is.

Everything inside the if(is_array()). Ummm, that should probably still be a
.= operator, then. There's also some quotes missing in the original
version, so:
if (is_array($_POST['state']))
$sql .= "state='".implode("' OR state='", $_POST['state'])."'";
Cheers!

Yeah, true -- I have a very bad tendency to forget about security considerations like
that until someone reminds me (often a posting on this list does it ;). Just because
I have a well-defined set of well-behaved users...!!

This check isn't really necessary in PHP, since $_POST['state'] will *always* be an
array if the form field has NAME='state[]', even if only 1 is selected.

PHP has the very nice implode function to make this much easier:
$sql = "state='".implode(' OR state=', $_POST['state'])."'";
(If your database supports the IN operator, this is probably even better:
$sql = "state IN ('".implode("','", $_POST['state'])."')"; )

Ditto for the job field.

I was waiting for someone to come in with a security warning, but knew that whoever it
was would express it much better than I could ;) -- so, a gold medal to John!!
