  1. Script 10#4 works for pagination, in my case 6 pages. Script 10#5 sort on First Name and Last Name work on the initial page display after selected column heading but not for selecting pages after the sort selection. My url shows view_users_3.php as I save each iteration of the scripts to review. Viewing my page then selecting sort by last name shows: url = view_users_3.php?sort=ln The first page of results displays correctly by last name. selecting the page 2: url = view_users_3.php?s=10&p=6&sortln The second page of results is showing user_id's 10 to 19 so has not sorted by last_name. The same situation occurs when I use First Name and Date Registered. I rechecked the code and noted lines 68-70 with the href tags (also from forum Sep 2013) not highlighted but cannot find any other difference with my code. My code: <?php # Chapter 10: Script 10.5: view_users_3.php //This script retrievs all the records from the users table. //This 10.5 version allows results to be sorted in different ways. $page_title = 'View the Current Users'; include ('../includes/header.html'); echo '<h1>Registered Users</h1>'; // Page header require_once ('../includes/mysqli_connect.php'); // Connect to the db. // Number of records to show per page. $display = 10; // Determine how many pages there are ... if (isset($_GET['p']) && is_numeric ($_GET['p'])) { // Already been determined. $pages = $_GET['p']; } else { // Need to determine. // Count the number of records. $q = "SELECT COUNT(user_id) FROM users"; $r = @mysqli_query ($dbc, $q); $row = @mysqli_fetch_array ($r, MYSQLI_NUM); $records = $row[0]; // Calcualte the number of pages... if ($records > $display) { // More than 1 page. $pages = ceil ($records/$display); } else { $pages = 1; } } // End of p IF. // Determine where in the database to start returning results... if (isset($_GET['s']) && is_numeric ($_GET['s'])) { $start = $_GET['s']; } else { $start = 0; } // Determine the sort... // Default is by registration date. $sort = (isset($_GET['sort'])) ? $_GET['sort'] : 'rd'; // Determine the sorting order. switch ($sort) { case 'ln': $order_by = 'last_name ASC'; break; case 'fn': $order_by = 'first_name ASC'; break; case 'rd': $order_by = 'registration_date ASC'; break; default: $order_by = 'registration_date ASC'; $sort = 'rd'; break; } // Define the query: $q = "SELECT last_name, first_name, DATE_FORMAT(registration_date, '%M %d, %Y') AS dr, user_id FROM users ORDER BY $order_by LIMIT $start, $display"; $r = @mysqli_query ($dbc, $q); // run the query. // Table header. echo '<table align="center" cellspacing="3" cellpadding="3" width="75%"> <tr> <td align="left"><b>Edit</b></td> <td align="left"><b>Delete</b></td> <td align="left"><b><a href="view_users_3.php?sort=ln">Last Name</a></b></td> <td align="left"><b><a href="view_users_3.php?sort=fn">First Name</a></b></td> <td align="left"><b><a href="view_users_3.php?sort=rd">Date Registered</a></b></td> </tr> '; // Fetch and print all the records. $bg = '#eeeeee'; // Set the initial background color. while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)) { $bg = ($bg=='#eeeeee' ?

($start - $display) . '&p=' . $pages . '&sort=' . $sort .

'&sort' . $sort . '">' . $i . '</a> '; } else { echo $i . ' '; } } // End of FOR loop. // If it's not the last page, make a Next button. if ($current_page != $pages) { echo '<a href="view_users_3.php?s=' . ($start + $display) . '&p=' . $pages . '&sort' . $sort . '">Next</a>'; } echo '</p>'; // Close the paragraph. } // End of links section. include ('../includes/footer.html'); ?>
