I'm using a pagination script for the front of my statistics website, and now i'm trying to put it in my search page. The search feature works, it displays the found user's. But it also displays everyone else on the next page.

 

I think it's gotta be one of the queries, but I can't seem to find it....

 

Can anybody help me out, please?

 

<?php

include 'db.php';

?>

1) The WHERE clause you are building and putting into the second query, must also be put into the first (COUNT()) query so that the $total_pages calculation will be correct for the number of records that match that WHERE clause.

 

2) You must carry the $_POST['searchterm'] value as a $_GET parameter in the url so that it will be present on each page request. Changing your search form to use method='get' would be acceptable since you are specifying what the page should output as the result of a request.

 

3) The pagination links that you produce must carry any existing $_GET parameters and just set the $_GET['page'] value. See the following post for how you can produce the pagination links so that they only set the $_GET parameter used for pagination and leave all other $_GET parameters as is - http://forums.phpfreaks.com/index.php?topic=348834.msg1646676#msg1646676
