I have a search form that goes to search.php?page=1 (has pagination). At the top of search.php I have:

PHP Code:

<?
session_start();
$_SESSION['keyword'] = $_POST["keyword"];
?>

Further in my code I explode $_SESSION['keyword'] (to alter the terms for boolean search), implode the terms and pass them off to my MySQL query. This all works, it returns the first page of results. Yet when I click the next page (search.php?page=2) it returns nothing, the session variable no longer exists.

Any ideas as to why this is happening? I'm not super great with sessions, but something simple like this should work.

Well, I figured out I was going about it the wrong way anyway. I was trying to recapture what I had already posted and altered for the boolean search. So had it worked, I would have resubmitted the boolean search to be altered for boolean search another time.

But I realized just a few minutes ago that once the script terminates I lose my keywords altogether.

PHP Code:

$keys = explode(" ", $_POST['keyword']); //back to original code w/o sessions
   foreach ($keys as $newkey) {
$var[] = "+$newkey";
}
$newkeys = implode(" ", $var);

// $newkeys is now +keyword1 +keyword2 etc.

// mysql [fulltext] query with $newkeys works

// print results just fine

echo $newkeys; // empty, well actually just + 


So I need to figure out how to keep $newkeys alive period, but through the pagination.

Oh well. I just passed everything through the URL. 2 minutes. No headaches.
