[SOLVED] Ending Sessions

[soycharliente]

What's the best way to clear session variables upon leaving a page?

Obviously I could set them to NULL or end the session on every other page, but that's a hassle.

Clear them, i.e. set to null or destroy them?

I only want these session variables to work on 1 page. So they are cleared when I go to any other page on the site. If I destroy the session on that page, it won't work if they submit the form that returns to the same page.

I only want these session variables to work on 1 page.

 

So only check for their presence on that page ... or is there rather more to this problem?

But won't they exist on every page? What do you mean? I don't understand.

you could try finding a javascript fucntion that says something like "on unLoad....session_destroy()".  Or you could create a small php script that gets run when the form is submitted.  So you'd have your "form_page"->"form_submission_page(mysql or whatever)"->"session_destroy_page"->"home_page"
