Re: [PHP-DB] Help with a query
Why not use: SELECT a.item_id, a.subtotal, a.quantity FROM shopping_cart a, orders b WHERE b.session_id = session_id() AND b.customer_id = $customer_id AND a.order_id = b.border_id ? !Exclude Disclaimer!

Re: [PHP-DB] Storing images in MySQL table
Milan, The only disadvantage i've had of storing images in DB instead of Filesystem, is that when you use a PHP script to output the image to a client browser, MSIE doesn't always accept a suggested filename so it might try and save it as your-script.php?img=2. Other then that, keeping images in DB is a lot easier since you don't have to keep your DB in sync with Filesystems ie. Deleted records in DB, but images still exist.

Re: [PHP-DB] More help with mysql
Yo Evan,
Have you got an '@' in front of the mysql_query() to supress errors ?

Hi all
I have successfully managed to connect to the mysql database, using the
following code:
mysql_connect('localhost','php','***') || die (Unable to connect to
MySQL server.);
$db = mysql_select_db(DB_NAME) || die (Unable to select requested
database.);
I then issue the following command:
$result = mysql_query(SELECT * FROM SOME_TABLE) || die(mysql_error());
This does not result in any error.
Now, of course, I want to work with the data returned, so I go:
if (mysql_num_rows($result) 0)
{
// do some stuff
}
else
{
// do some other stuff
};
However, this gives me: Supplied argument is not a valid MySQL result
resource.
If I go: echo $result, I get '1', so I know $result actually has some
value.
What am I doing wrong? Basically, I want to do the simplest thing: get data
out of a table and step through the results, displaying them one by one. Why
is this hard?

Re: [PHP-DB] Multiple select box using mysql
You have to give the Mutli select box a name as an array. eg:
SELECT NAME=experts[] MULTIPLE SIZE=5
OPTION VALUE=key1val1/OPTION
/SELECT
then in PHP, you can access $experts as an array.
while (list ($key, $val) = each($experts)) {
print $key = $valBR\n;
}

I writing a software catalog that features experts,

I need to have a page that generates 2 multiple select
boxes, each on with the data from each table.
From there one will be able to choose the software
program and the experts, which will then record the
software-expert relationship in the DB.
The problem is that I don't really understand how to
populate multi select boxes with db data, and then
have the selections passed back as inserts.
Can someone clue me in?
