[Resolved] Session variables with jump menus

[sbauman]

Ok this gets complicated. I have my login script working ok. It creates a session variable called 'username' being the email address. After a user logs in, I want them to go to a page that lets them upload a picture with a description. The description is created using a set of drop down lists (jump menus). The upload works and the insert into my database works but I need the session variable 'username' to put the user ID number associated with it into a hidden field and insert it into the database attached to the picture that is uploaded. Does this make sense?😕 I'm new to session variables so I'm not sure how these move throughout the pages and pull different information from the user's record. Any help is appreciated. Thank you! 🙂

hope I understood ...

normally there is no need to put data from a session variable into a hidden input in order to process the information along with the form data.

this is because in every script which has a session_start() call, session variables are directly available (via $_SESSION['username'] or directly as $username, depending on the coniguration). this is valid for the form processing script, too - you can draw username from the session and process it. no need to have it in the post data instead.

How do I reference the ID number and make it insert into the correct field in the database then? Do I have to call a new recordset based on the 'username'?

Ok i figured it out. I needed to put the session_start() on each of the pages. It wasn't reading the variables otherwise. I didn't know that. Thanks for the help!
