Multiple form mysql query and pages numbering

[Eiffelmtl]

Hello everyone,

I'm not not an expert in php and this is why I write on this forum.

I have a page with two search form (one per category, the other by age group) and I display my results from a query with pagination.

All good until I move from one page to another: as soon as I change the page I lose my list of results and my page does not show anything other than my form.

I did a print_r of my sessions and the launch of my page I have:

Array()

Once my form send I got for exemple:

Array ( [categorie] => 4 )

But when I go to another page of my result, I go back to:

Array()

Can you help me or at least tell me how to fix the problem?

Thank you very much

It sounds like you're passing the information using a SESSION variable. On the page which as a problem with the variable, did you call session_start() at the top?

I see session_start() buried in your code...long after you've already output stuff. It must come before any output. It must come before output because session variable uses a session cookie. cookie must be sent in the response headers. If you output something before starting the session, headers are already sent and cookie cannot be sent. If you have your error settings set to display warnings, you should see a "warning: headers already sent" error message output from this.
