Pagination Help

kampbell411

Hi,

I was wondering if someone could help with pagination. I am able to display the results and the number of results I want per page. The problem i am having is that when i go to the next page the same results as the first are returned. The URL does change except when the next set of results are shown, its the same as the first. Below is my code. Thanks in advance.

<?php
// Connects to your Database
mysql_connect("localhost", "root", "root") or die(mysql_error()) ;
mysql_select_db("dbname") or die(mysql_error()) ;

//Pagination
//This checks to see if there is a page number. If not, it will set it to page 1
if (!(isset($pagenum)))
{
$pagenum = 1;
}

//Retrieves data from MySQL
$data = mysql_query("SELECT * FROM events") or die(mysql_error());
$rows = mysql_num_rows($data);

//Pagination Continued
//This is the number of results displayed per page
$page_rows = 3;

//This tells us the page number of our last page
$last = ceil($rows/$page_rows);

//this makes sure the page number isn't below one, or more than our maximum pages
if ($pagenum < 1)
{
$pagenum = 1;
}
elseif ($pagenum > $last)
{
$pagenum = $last;
}

//This sets the range to display in our query
$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows;

//Retrieves data from MySQL
$data_p = mysql_query("SELECT * FROM events $max") or die(mysql_error());

//Puts it into an array
while($info = mysql_fetch_array( $data_p ))
{

//Outputs the image and other data
Echo "<img width='150px' height='150px' src=http://localhost:8888/dbname/images/".$info['photo'] ."> ";
Echo "Name: ".$info['name'] . " ";
Echo "Date: ".$info['date'] . " ";
Echo "Description: ".$info['description'] . " <hr>";
}

// This shows the user what page they are on, and the total number of pages
echo " --Page $pagenum of $last-- ";

// First we check if we are on page one. If we are then we don't need a link to the previous page or the first page so we do nothing. If we aren't then we generate links to the first page, and to the previous page.
if ($pagenum == 1)
{
}
else
{
echo " <a href='{$SERVER['PHP_SELF']}?pagenum=1'> <<-First</a> ";
echo " ";
$previous = $pagenum-1;
echo " <a href='{$SERVER['PHP_SELF']}?pagenum=$previous'> <-Previous</a> ";
}

//just a spacer
echo " ---- ";

//This does the same as above, only checking if we are on the last page, and then generating the Next and Last links
if ($pagenum == $last)
{
}
else {
$next = $pagenum+1;
echo " <a href='{$SERVER['PHP_SELF']}?pagenum=$next'>Next -></a> ";
echo " ";
echo " <a href='{$SERVER['PHP_SELF']}?pagenum=$last'>Last ->></a> ";
}
?>

i think's u may be forget little somethint..

$pagenum variable has never to setup, coz this variable never asign from parameter in the address bar..

//so add this code

$pagenum = $_GET["pagenum"]; 

//This sets the range to display in our query
$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows;
