Hi Folks,
I have found this nice pagination script that works fine except when I’m trying to use variables in the query.
The first step I try to get working is a variable for clientid. The meny passes this ($cid) to the content page and the record counting, and here it works fine. I get the corrects page numbers and I also get the first image showing, but when I click for page 2 it obviously looses this variable and I get an limit error.
I have tried to send the variable but it’s not working. $pages->client is what I tried. In the paginator.class.php I have added cid=$client in the page links but it gets no variable.
Here is the code in the content page:
$cid = (int)($_GET['cid']);
// Full Size View of Content with Pagination
$query = "SELECT COUNT(*), clientid FROM content WHERE sectorid=6 AND subsectorid=7 AND clientid=$cid";
$numbers = mysql_query($query);
$num_rows = mysql_result($numbers, 0);
require_once('../code/paginator.class.php');
$pages = new paginator;
$pages->items_total = $num_rows;
$pages->mid_range = 7;
$pages->paginate();
$pages->client = $cid;
$result = @mysql_query( "SELECT photo_id, photo_filename, engtext FROM content WHERE clientid=$pages->client AND sectorid=6 AND subsectorid=7 ORDER BY photo_id DESC $pages->limit " );
if (!$result) {
exit('<p>Error performing query: ' . mysql_error() . '</p>');
}
while ($images = mysql_fetch_array($result)) {
$image = $images['photo_filename'];
$caption = $images['engtext'];
echo "<img src='../photos/$image' border='0' /><br /><span class='caption'>$caption</span>";
}
This is the paginator:
echo $pages->display_pages();
and this is the paginator.class.php:
class Paginator{
var $items_per_page;
var $items_total;
var $current_page;
var $num_pages;
var $mid_range;
var $low;

var $return;
var $default_ipp = 1;
var $client;
