Hi and thank you for reading my post.
I have this pagination script and everything seems to work expect from when I click on the next page it dosent actually jump to next page, can anyone please help me with correcting this?
here is the code:
<?php
// Connects to your Database
mysql_connect("localhost", "username", "password") or die(mysql_error());
mysql_select_db("database") or die(mysql_error());
//This checks to see if there is a page number. If not, it will set it to page 1
if (!(isset($pagenum)))
{
$pagenum = 1;
}
//Here we count the number of results
//Edit $data to be your query
$data = mysql_query("SELECT * FROM people ORDER BY issuenams ") or die(mysql_error());
$rows = mysql_num_rows($data);
//This is the number of results displayed per page
$page_rows = 40;
//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)
{
$pagenum = 20000;
}
elseif ($pagenum > $last)
{
$pagenum = $last;
}
//This sets the range to display in our query
$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows;
//This is your query again, the same one... the only difference is we add $max into it
$data_p = mysql_query("SELECT * FROM people, articles, issues $max") or die(mysql_error());
echo "<table bgcolor='#cccccc' align='center' border='1' width='700'>";
echo "<tr> <th>Artist</th> <th>Date</th> <th>Keywords</th> <th>Issue</th> </tr>";
//This is where you display your query results
while($info = mysql_fetch_array( $data_p ))
{
echo "<tr><td width='25%'>";
Print $info['PeopleName'];
echo "</td>";
echo "<td width='25%'>";
Print $info['Date'];
echo "</td>";
echo "<td width='25%'>";
Print $info['Keywords'];
echo "</td>";
echo "<td width='25%'>";
Print $info['IssueName'];
echo "</td>";
}
echo "<p>";
// This shows the user what page they are on, and the total number of pages
echo " --Page $pagenum of $last-- <p>";
// First we check if we are on page one. If we are then we don't need a link to the previous page or the first page so we do nothing. If we aren't then we generate links to the first page, and to the previous page.
if ($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> ";
}
?>
Thank you.

Re: php/mysql pagination
You haven't defined $pagenum anywhere. You need to do something like
Code: Select all
$pagenum = $_GET['pagenum'];
