Okay, so i get this error on line 19 in this pagination script.
The error goes like this:
Notice: Undefined index: page in C:\wamp\www\pagination.php on line 19
This is wrong: $page = $_GET;
But i don't realy understand what is wrong, because the targetpage is set to "pagination.php".
Maybe it's worth metioning that the pagination.php file is included in the index.php file. Maybe i should have just put the code right in the index.php file instead of including it?
<?php
include 'script_dbconnect_pc.php';
// My table name.
$tbl_name="images";
// How many adjacent pages should be shown on each side?
$adjacents = 5;
$query = "SELECT COUNT(*) as num FROM $tbl_name";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages['num'];
/* Setup vars for query. */
$targetpage = "pagination.php"; //Filename (name of this file).
$limit = 6; //How many items per page (pictures).
$page = $_GET['page'];
if($page)
$start = ($page - 1) * $limit; //First item to display on this page.
else
$start = 1; //If no page var is given, set start to 0.
/* Get data. */
$sql = "SELECT * FROM $tbl_name ORDER BY $tbl_name.`id` DESC LIMIT $start, $limit";
$result = mysql_query($sql);
/* 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.
