How to Implement Pagination in PHP & MySQL for a \'redirect\' Table?

PHP & MySQL Pagination: A Comprehensive Guide

Problem:

You have a MySQL query that retrieves data from the 'redirect' table based on a specific 'user_id' and sorts the results by 'timestamp'. You need to implement pagination to display 10 results per page.

Solution:

To perform pagination in PHP:

<code class="php"><?php

// Insert your MySQL connection code here

// Define variables
$perPage = 10;
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$startAt = $perPage * ($page - 1);

// Get total number of rows
$query = "SELECT COUNT(*) as total FROM redirect
WHERE user_id = '".$_SESSION['user_id']."'";
$r = mysql_fetch_assoc(mysql_query($query));

// Calculate total number of pages
$totalPages = ceil($r['total'] / $perPage);

// Generate pagination links
$links = "";
for ($i = 1; $i <= $totalPages; $i++) {
  $links .= ($i != $page ) 
            ? "<a href='index.php?page=$i'>Page $i</a> "
            : "$page ";
}

// Execute query with pagination applied
$query = "SELECT * FROM 'redirect'
WHERE 'user_id'= \''.$_SESSION['user_id'].' \' 
ORDER BY 'timestamp' LIMIT $startAt, $perPage";

$r = mysql_query($query);

// Display results ...

// Echo pagination links
echo $links; // show links to other pages</code>
