Hi everyone forgive me I am a little new to php but I can get by....
I am trying to implement a pagination script into my sub cat page in a shop however I ahve most of it done but cannot seem to get the pageination to show can someone please put my back on tracks I am getting confused.
I have included my code so you can see thanks in advanced.
<?php
$shopcatid = $_GET['id'];
$shopsubcatid = $_GET['s'];
// How many adjacent pages should be shown on each side?
$adjacents = 3;
/*
First get total number of rows in data table.
If you have a WHERE clause in your query, make sure you mirror it here.
*/
$query = "SELECT COUNT(*) as num FROM shopcatid = '" . $shopcatid . "' AND shopsubcatid = '" . $shopsubcatid . "'";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];
/* Setup vars for query. */
$targetpage = "sub-category.php"; //your file name (the name of this file)
$limit = 9; //how many items to show per page
$page = $_GET['page'];
if($page)
$start = ($page - 1) * $limit; //first item to display on this page
else
$start = 0; //if no page var is given, set start to 0
/* Get data. */
$query = "SELECT * FROM shop_products WHERE shopcatid = '" . $shopcatid . "' AND shopsubcatid = '" . $shopsubcatid . "' LIMIT $start, $limit";
$result = mysql_query($query) or die( "An error has occured: " .mysql_error (). ":" .mysql_errno ());
/* Setup page vars for display. */
if ($page == 0) $page = 1; //if no page var is given, default to 1.
$prev = $page - 1; //previous page is page - 1
$next = $page + 1; //next page is page + 1
$lastpage = ceil($total_pages/$limit); //lastpage is = total pages / items per page, rounded up.
$lpm1 = $lastpage - 1; //last page minus 1
/*
Now we apply our rules and draw the pagination object.
We're actually saving the code to a variable in case we want to draw it more than once.
*/
$pagination = "";
if($lastpage > 1)
{
$pagination .= "<div class=\"pagination\">";
//previous button
if ($page > 1)
$pagination.= "<a href=\"$targetpage?page=$prev\">« previous</a>";
else
$pagination.= "<span class=\"disabled\">« previous</span>";
//pages
if ($lastpage < 7 + ($adjacents * 2)) //not enough pages to bother breaking it up
{
for ($counter = 1; $counter <= $lastpage; $counter++)
{
if ($counter == $page)
$pagination.= "<span class=\"current\">$counter</span>";
else
$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";
}
}
elseif($lastpage > 5 + ($adjacents * 2)) //enough pages to hide some
{
//close to beginning; only hide later pages
if($page < 1 + ($adjacents * 2))

//in middle; hide some front and some back
elseif($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2))
