Here's a function I wrote to do that. I can't promise that it isn't still
buggy, but it's been working on my forum for a while now.
/*************************************************************************/
/* print nextLinks
* Prints a list of "next page" links for a list of items
* spanning more than one page.
* The links look something like this:
* Page 1 | 2 | 3
* It cycles through the array of IDs supplied by the user
* and prints one every "itemsPerPage" interval
* param idArray - an array of all the id numbers of the thing that the menu
relates to
* param pageURL - the actual url for the pages that are linked
* param itemsPerPage - the number of items per page
* param currentID - the ID of the last item on the current page
*/
function printNextLinks($idArray, $pageURL, $itemsPerPage, $currentID,
$direction) {
// variables
$postCount = count($idArray);
$postPlace = 0;
$iteration = 1;
$threadLinks = "";
$lastID = $idArray[$postCount - 1];
$firstNextPage = $idArray[0];
// we only want the pages link if there is more than one page
if ($postCount > $itemsPerPage && $firstNextPage != '') {
while($postPlace <= $postCount && $firstNextPage != '') {
$thisID = $idArray[$postPlace];
$nextPlace = $postPlace + $itemsPerPage;
$lastCurrentPage = $idArray[$nextPlace - 1];
$firstNextPage = $idArray[$nextPlace];
if($lastCurrentPage == "") {
$lastCurrentPage = $thisID;
} // end if
if(($currentID == $lastCurrentPage) && ($thisID != '') &&
$direction == "desc") {
$threadLinks .= " $iteration |";
} else if (($currentID == $lastID) && ($firstNextPage == '') &&

$iteration ++;
