Question

I am trying to build a basic search but am getting a small code issue here, i want to paginate my searched result set and this is what i have
1) an input field named “input”, a and within a form of post method
2) when user submits the form it calls search.php with the follow code bellow.

The problem

the pagination returns a properly paginated result set but when i move to next page all records in the search table are returned including those that do not meet the criteria in the where clause.

Here is the code: Let me know if it’s too much code here. I can paste somewhere else and provide a link;
Thanks guys

It’s certainly because when you go to a next page, you don’t send again these values :

$input = $_POST['input'];
$categories = $_POST['category'];
$state = $_POST['state'];

which correspond to your filters values. Surely they become empty.

Hope this helps.
