Moving the mysql connection to the next web page

I'm running linux/php/apache to manipulate a mysql data base.

The user enters a userId and password. I connect to the mysql data base using -

$linkId = mysql_connect( 'localhost', $userId, $password );

And I can do some queries, etc. (it's fine up to here).

Via a "submit" button, I go to another web page. I want to do more data base queries in this page.

Do I have to do another mysql_connect in the next web page?
Do I have to pass the userId and password to the next web page via hidden text fields?
Can I send the $linkId to the next web page? (equals "resource id #1" or some such. Doesn't work)

You can close the db connection and open a new one on every page... doesnt take a lot of resources.

As for the username and password, you can store them in session variables.

OK, so if I set a session variable on web page 1, can I reference and use it on web page 2.

I tried session variables. The web page where the variables were set seemed to remember the values, but the other web pages didn't know anything about these variables.

User error??

You need to start the session on each page using the session_start() function.

Dont forget to close the db connection on each page using mysql_close($linkId);

normally you open a different mysql connection for each webpage you view.

If you want to reduce the connection overhead, and connect only once check out mysql_pconnect. mysql_pconnect only works if you are using an apache module.

You cannot maintain a connection between different CGI scripts.
