[PHP-DB] mysql_insert_id - link_identifier
Hello,
How do I use the linkidentifier to get me the last_inserted_id
(mysql_insert_id) from a auto_increment-colomn?
Do I use:
>>
$q_orders_id2 = "INSERT INTO orders(orders_datum, orders_sessid)";
$q_orders_id2.= " VALUES ('$date', '$sid')";
$r_orders_id2 = mysql_query($q_orders_id2, $sqllink_id);
$orders_id = mysql_insert_id($sqllink_id);
<<
"$sqllink_id" must be the inserted value for the auto-increment-colomn named
"orders_id" and is placed in var "$orders_id"
Can anyone tell me if this is correct and what can be done to optimize?
regards
Bart

[PHP-DB] mysql_insert_id - link_identifier
I already run the query without the value of the primary-key field:
>>
$q_orders_id2 = "INSERT INTO orders(orders_datum, orders_sessid)";
$q_orders_id2.= " VALUES ('$date', '$sid')";
$r_orders_id2 = mysql_query($q_orders_id2, $sqllink_id);
$orders_id = mysql_insert_id($sqllink_id);
<<
The primary-key field is: "orders_id" (not in above query).
Only "orders_datum" and "orders_sessid" are sent with the query.
When I call mysql_insert_id with tha vars: "$q_orders_id" or
"$r_orders_id" I get an warning (Warning: Supplied argument
is not a valid MySQL-Link resource in /home/httpd/blabla/file.php
on line 91) but not the wanted id.
In the manual it says that mysql_insert_id() is used with the
linkidentifier ($sqllink_id ? ) but not how to define the identifier
in mysql_query()...
>>How do I define a linkidentifier for a specific call to
mysql_query() and then use mysql_insert_id() with that
linkidentifier of the query?

[PHP-DB] session_registered variable problem
Hello! I have a problem with session_registered variables. It seems that my sessions behave quite erratic. Well, actually just one variable, $query. Somehow when I print the value of $query, it looks fine. Then, when I change $query a bit and print it again, it looks fine. Change it a third time, and it suddenly gets the value it had in the beginning. Ideas as to how one would go about solving this little problem?

When you initiate the connection to the db using mysql_connect() or
mysql_pconnect() it returns a MySQL link identifier.
In most cases you do NOT need to specify the link identifier when using
mysql_query(). If you're only dealing with one database throughout your
script then there's no reason for you to specify the link identifier because
PHP automatically uses the most recently used one. That is it automatically
chooses the correct link identifier to use.
So in your case what you want would probably be something like this:
$q_orders_id2 = "INSERT INTO orders(orders_datum, orders_sessid)";
$q_orders_id2 .= " VALUES ('$date', '$sid')";
# for debugging, you may want to echo $q_order_id2
$r_orders_id2 = mysql_query($q_orders_id2);
$orders_id = mysql_insert_id();

Well, for instance, this screws up the $query. It works if one clicks
once on the next-button, but clicking another time resets the query to
SELECT
L.Tunnus,N.Nimi,L.ISSN,L.Vuosi,L.Lisätietoja,L.Vuosikerta,L.Numerot,L.Huomautuksia
FROM uusi_lehtitaulu L, nimet N
WHERE (L.Nimi_id=N.id AND N.Nimi LIKE "asdf")
LIMIT 0,20
if($go=="next") {
if($page < $nr_pages && $page >= 0) {
$page++;
$replace_with= (($page) * 20).",";
echo "replace_with: " . $replace_with;
$replace = (($page-1) * 20).",";
echo "replace: " .$replace;
$query=ereg_replace($replace,$replace_with,$query);
}
}
It's the LIMIT 0,20 -> LIMIT 20,20 -> LIMIT 40,20 that doesn't work. Strange thing is,
that
it worked about a week ago. : \
I can't really recall changing that part of the code at all at that point.
Cheers,
Markus

RE: [PHP-DB] [PHP] PHP and MYSQL Security`
What I do, because I am using a test platform is to put the line with
pconnect() in a small text file, place this file somewhere on the disk,
outside of the web site root
and refer to that file with include() in my code.
This way, even if the PHP source code were compromised, the user name
and password used to access the DB cannot be seen.

Crikey, it looks terribly complicated for what looks like something to page
through a set of results.
Wouldn't it be easier to do away with the ereg_replace()?
if($go=="next") {
if($page < $nr_pages && $page >= 0) {
$page++;
$start = $page * 20;
}
}
$qry = "SELECT
L.Tunnus,N.Nimi,L.ISSN,L.Vuosi,L.Lisätietoja,L.Vuosikerta,L.Numerot,L.Huom
autuksia FROM uusi_lehtitaulu L, nimet N
WHERE (L.Nimi_id=N.id AND N.Nimi LIKE "asdf")
LIMIT $start,20"
Even it this doesn't work, at least it's easier to understand :)

Well, in this particular case it won't work at all, because the SQL-query is
dynamically
created based on what the user wants to search for. It doesn't nessecary include all
columns. The only static bit of the query is "FROM uusi_lehtitaulu L, nimet N" and
"WHERE (L.Nimi_id=N.id" : ) It would be just as big a mess with a truckload of
concatenations, like
$query = "SELECT " . $tables . " FROM uusi_lehtitaulu L, nimet N WHERE
(L.nimi_id=N.id" . $search . ") LIMIT $start,20";
Besides, I have a strange fetisch to do everything the hard way. : )

[PHP-DB] UPDATE query to add to a field
hello all: I need to be able to update a field in MySQL, the catch is that I have to add on to text that is already there and I have to be able to do it within MySQL (phpMyAdmin). My first idea was to do: SET prod_desc = prod_desc + "more info to tack on to end" but this is a mathematical function which returns 0! Any ideas?

RE: [PHP-DB] [PHP] PHP and MYSQL Security`
I've figured out a fairly secure program structure. Here's one option
(I'm sure there's as many ways to accomplish similar security as there
are people on this list):
First, a little info about the environment. It's a Linux OS running
Apache Web Server. Multi-user environment providing hosting to multiple
domains. Development is done on Windows boxes.
Now, to accomplish security and keep it relatively well hidden took some
doing. First, I use what I call 'control files'. These are the only
files in the Web accessible directory tree (i.e.
www.interkan.net/News/index.phtml). These files contain only code to
process submitted commands (or default ones should no command be
submitted) and include the proper files (config module which is where
the mySQL access info is stored, global code libraries, and the actual
code modules to handle submitted data).
The included modules are all kept in a PHP include directory in the
appropriate user directory (i.e. /home/user/php-inc/). Due to
restrictions, we have to have the files themselves with 644 permissions
(so the Web server can read them), but the directory permissions for
php-inc and php-inc/ are set to 711. The permissions work out
that no one can read the files unless they (1) know the exact path and
filename and (2) have shell access to the server (the only people that
have that are employees).
This helps in a couple ways. If the PHP process ever dies, all someone
will see when going a PHP file is the file comment block, the file
include information (not necessarily good, but they'd have to get into
the server with a shell account first), and some if and switch
statements. It also narrows down any security breaches to someone who
had access to the system, instead of the entire Internet community.

[PHP-DB] storing and retrieving arrays in mysql
Hi folks, I've got a question hopefully someone can shed some light on for me. I'm building an online store for a client, and one of the things he wants is to organize his products into categories and subcategories.. not so unusual, but the kicker is he wants to be able to associate a subcategory with more than one category. I was thinking that I should be able to easily serialize an array of cat_IDs and store it, but my concern is that this will sacrifice a great deal of flexibility when retrieving the data. For instance when I want to get the subcategories in a single category, I would pretty much have to select ALL the rows in the subcategory table, unserialize the category array for each row, and then check each to see if the cat_ID is in the array..? That just feels inefficient to me, and I'm almost certain I must be overlooking something simpler.. Also, I don't think I can use a SET data type because I want to be able to add values to the set (categories) dynamically in the future. But maybe I'm wrong and there is a way to do that...? Anyway I thought I'd throw it to those more experienced than me before I started coding. Anyone have any ideas?

Re: [PHP-DB] storing and retrieving arrays in mysql
I've done something similar by building a multidimensional array of categories and subcats in one query and then Loop thru this with a for each to build the category structure. Categories table looks like this CatID | ParentID | CategoryName Array is $category_menu[$ParentID][$CatID] I'm sure there's a better way, but this seems to work OK. I will email code sample later [off-list]. I would be happy to share code with others as well. olinux --- Corey Eiseman <[EMAIL PROTECTED]> wrote: > Hi folks, I've got a question hopefully someone can > shed some light on for > me. > > I'm building an online store for a client, and one > of the things he wants is > to organize his products into categories and > subcategories.. not so unusual, > but the kicker is he wants to be able to associate a > subcategory with more > than one category. > > I was thinking that I should be able to easily > serialize an array of cat_IDs > and store it, but my concern is that this will > sacrifice a great deal of > flexibility when retrieving the data.

RE: [PHP-DB] storing and retrieving arrays in mysql
I've been working on something like this since about September/October.
It's not too hard, but it did take more coding than I thought it would.
Now, there's a couple of ways you could do this. I chose the cheap (in
terms of the number of DB tables) way out.
The way I have it set up is this. You have certain categories ("Main"
categories) that have a parent category of ',0,' (I found I had to
enclose the categoryIDs in commas to prevent accidentally selecting a
category that matched any of the digits of any other categoryID in the
same order) then I have the subcategories which have multiple parents.
The form to add a new product gathers all the information I need --
category name/title, description, whether it should be displayed and the
parent category(s), with the parent categorys being displayed in the
form of checkboxes. This lets the admin select multiple categories for
the parent (we have a similar set up for the products since a product
can belong in multiple categories).
The checkboxes themselves are named p_id (I think) and are an array,
thus I print the name value as NAME='p_id[" . $cid . "]', where $cid is
the variable containing the category ID (I actually have it in a
recordset array, of course). Then, it just prints a p_id checkbox for
each possible parent (obviously when editing the category ID of the one
being edited isn't printed). When editing, those categories to which
the category has as parents are checked.
When the form is submitted, it puts the posted variable values (the
array of checkboxes) into a comma-delimited string. Whenever I query
the database for subcategories, unfortunately, I have to make sure I
remember to check for parent LIKE '%,ID,%' so I don't pick up one I
don't want (i.e. if I were to say LIKE '%ID%' and I was looking for ID =
20 and had that and ID =200, subcategories with parents of category 20
and 200 would end up returned). That's how I handled it. I'm probably
going to upgrade to this next option later on, though.
Create a table for the categories and then a table that determines a
category's children. Basically, it's just two fields: categoryID and
parent -- with both fields making up the primary key. Then, for each
parent category they checked on the form, insert the new category's ID
in the categoryID field and the parent's ID into the parent field.
That's probably the best way since it would probably cut down on space
(I use a TEXT field currently, whereas the second option could be done
with two MEDIUMINT fields).
If you want some code samples, e-mail me privately. If you want to see
the script (version 1.5.23 -- we've got 2.0 almost finished up now) in
action, we've got one of our clients playing guinea pig at

[PHP-DB] ensuring unique field value in MySQL using PHP
I have a form in which users create their own login name. The code for
storing the login name they created does something like the following:
$userlogin is the name the user typed in the form
$sql = "select loginname from login where loginname='$userlogin'";
$result=mysql_query($sql);
$num=mysql_num_rows($result);
if ($num > 0)
{
echo "Sorry, that login name is already taken, Try another";
shows form again;
}
else
insert new record into database;
echo "okay, your new account is added";
I am wondering if it is possible that two people could hit the submit button
at the exact same time with the same login name so that the same login name
could get entered twice? Seems unlikely that this would happen by accident,
but is this something a hacker could do on purpose?
Thanks,
Janet

[PHP-DB] RE: ensuring unique field value in MySQL using PHP
Checking a small database for username/password combination would happen so
quick, it would be nearly impossible for two usernames to be entered in.
Your script should work properly, but to make sure no duplicates are
entered, you can change the column definition using the "ALTER columnName"
command to make sure there are no duplicates. Look in the mySQL
documentation (www.mysql.com) to find the correct command.

I suggest that you cache as much content as you can to avoid hitting the database. One technique that I use in the PHP Classes site is to cache content indefinitly. Then when the data that defines that content is changed I call a method of my cache file class to void the cache, so it will force the cached data if and when it is needed on the next access for a page that uses that. This way I don't retard the database update process and the cache is only generated if it will ever be need. So I avoid having situations where more than one update is made to the database before the cached data needs to be redisplayed. For making your site static as much as possible, I usually recommend the "page fault" technique. That consists of static pages that are deleted when their content is updated. When there is a request for them, since when they are missing the server redirects the request to your error document. That is where you regenarate the page file with upto date data. While the page is upto date it remains in the disk and is served as static page at the server top speed (no scripting language nor database to clutter the access).

[PHP-DB] Date operations.
Hi All, I have a problem working out a suitable algorithm either in PHP or MySQL. Basically I have a DB that keeps track of breeding records. Each record has a paired data, and a split-up date. I need to generate some statistics to work out average numbers of pairs per month, averaged on a daily basis, for a given start and stop date, typically a year or year-to-date. All the algorithms I can think of are messy, where I have to loop through all the breeding records for every day of the year, and count how many pairs are breeding by seeing if the date is between the start and stop dates, and then average that on a monthly basis. I can't see that scaling very well, as there might be several hundred breeding records for a given year, multiplied by 365 days. Has anyone any hints/pointers for an efficient way to do this?
