I am unable to maintain a GET variable with this pagination script. Was hoping you all could help.
I am using a GET function so the user can choose which categories are displayed. I'm using a pagination script I found online and I am now confronted with this issue, when I choose "page 2" $dynCat no longer is parsed in the URL because the pagination script creates a new URL and uses GET also.
Could someone help me out with using pagination with a variable query? Thank you.
ERROR Notice: Undefined index: dynCat ----/dynCat.php on line 32
I understand why it is undefined, I just don't know how to integrate and maintain the user's Query (i.e. GET variable from URL) with the pagination script. Thanks again.
