Hi All, I'm currently working in Chapter 10 with the delete user script. I have followed the code in the book as itis but when I click "delete" from the view users page I keep getting "this page has been accessed in error". The only difference that I can see in my code and the book's is that my script is called "delete.php" and the book's is "delete.php". I have changed the name in the script to be correct. Also in the book the DB is named "users" but mine is called "user". The DB connection works fine as I can see my list of registered users. When I land on the delete a user page I can see my header and the <h2> tag "Delete a user" and my footer but no form to actually delete the user. My code is below. I'm probably doing something really stupid but any help would be great. thanks, Tony. <?php # Script 10.2 - delete.php $page_title = 'Delete a User'; include ('_include/header.php'); echo '<h2>Delete a User</h2>'; // Check for a valid user ID, through GET or POST: if ( (isset($_GET['id'])) && (is_numeric($_GET['id'])) ) { // From view_users.php $id = $_GET['id']; } elseif ( (isset($_POST['id'])) && (is_numeric($_POST['id'])) ) { // Form submission. $id = $_POST['id']; } else { // No valid ID, kill the script. echo '<p class="error">This page has been accessed in error.</p>'; include ('_include/footer.php'); exit(); } require_once ('../../mysqli_connect.php'); // Check if the form has been submitted: if ($_SERVER['REQUEST_METHOD'] == 'POST') { if ($_POST['sure'] == 'Yes') { // Delete the record. // Make the query: $q = "DELETE FROM user WHERE user_id=$id LIMIT 1"; $r = @mysqli_query ($dbc, $q); if (mysqli_affected_rows($dbc) == 1) { // If it ran OK. // Print a message: echo '<p>The user has been deleted.</p>'; } else { // If the query did not run OK. echo '<p class="error">The user could not be deleted due to a system error.</p>'; // Public message. echo '<p>' . mysqli_error($dbc) . '<br />Query: ' . $q . '</p>'; // Debugging message. } } else { // No confirmation of deletion. echo '<p>The user has NOT been deleted.</p>'; } } else { // Show the form. // Retrieve the user's information: $q = "SELECT CONCAT(last_name, ', ', first_name) FROM users WHERE user_id=$id"; $r = @mysqli_query ($dbc, $q); if (mysqli_num_rows($r) == 1) { // Valid user ID, show the form. // Get the user's information: $row = mysqli_fetch_array ($r, MYSQLI_NUM); // Display the record being deleted: echo "<h3>Name: $row[0]</h3> Are you sure you want to delete this user?"; // Create the form: echo '<form action="delete.php" method="post"> <input type="radio" name="sure" value="Yes" /> Yes <input type="radio" name="sure" value="No" checked="checked" /> No <input type="submit" name="submit" value="Submit" /> <input type="hidden" name="id" value="' . $id . '" /> </form>'; } else { // Not a valid user ID. echo '<p class="error">This page has been accessed in error.</p>'; } } // End of the main submission conditional. mysqli_close($dbc); include ('_include/footer.php'); ?>
