Hi, I also have this exact problem and have been stuck on it for a while. Does anyone have any answers yet? Thanks in advance! Zie

Hi daviddawn, I just wanted to thank you again for all your help. I re-downloaded the files from the site, made the require_once change on the add_pages.php file and when I uploaded it to the server, I checked the "overwrite previous files" and IT WORKED!! Zie

Thanks so much for your help! The errors seem to be coming from the form_functions.inc.php file. I have made changes on line 87, even deleting it entirely (it's actually just a comment) and I still get the same error. I also changed the add_pages file to require_once for including the form_functions.inc.php file. Here is a copy of the form_functions,inc.php file unchanged from the source file which is how I had uploaded it to the server originally: I have highlighted lines 13 and 87 in red <?php // This script defines any functions required by the various forms. // This script is created in Chapter 3. // This function generates a form INPUT or TEXTAREA tag. // It takes five arguments: // - The name to be given to the element. // - The type of element (text, password, textarea). // - The label for the element // - An array of errors. // - An array of additional options. function create_form_input($name, $type, $label = '', $errors = array(), $options = array()) { // Assume no value already exists: $value = false; // Check for a value in POST: if (isset($_POST[$name])) $value = $_POST[$name]; // Strip slashes if Magic Quotes is enabled: if ($value && get_magic_quotes_gpc()) $value = stripslashes($value); // Start the DIV: echo '<div class="form-group'; // Add a class if an error exists: if (array_key_exists($name, $errors)) echo ' has-error'; // Complete the DIV: echo '">'; // Create the LABEL, if one was provided: if (!empty($label)) echo '<label for="' . $name . '" class="control-label">' . $label . '</label>'; // Conditional to determine what kind of element to create: if ( ($type === 'text') || ($type === 'password') || ($type === 'email')) { // Start creating the input: echo '<input type="' . $type . '" name="' . $name . '" id="' . $name . '" class="form-control"'; // Add the value to the input: if ($value) echo ' value="' . htmlspecialchars($value) . '"'; // Check for additional options: if (!empty($options) && is_array($options)) { foreach ($options as $k => $v) { echo " $k=\"$v\""; } } // Complete the element: echo '>'; // Show the error message, if one exists: if (array_key_exists($name, $errors)) echo '<span class="help-block">' . $errors[$name] . '</span>'; } elseif ($type === 'textarea') { // Create a TEXTAREA. // Show the error message above the textarea (if one exists): if (array_key_exists($name, $errors)) echo '<span class="help-block">' . $errors[$name] . '</span>'; // Start creating the textarea: echo '<textarea name="' . $name . '" id="' . $name . '" class="form-control"'; // Check for additional options: if (!empty($options) && is_array($options)) { foreach ($options as $k => $v) { echo " $k=\"$v\""; } } // Complete the opening tag: echo '>'; // Add the value to the textarea: if ($value) echo $value; // Complete the textarea: echo '</textarea>'; } // End of primary IF-ELSE. // Complete the DIV: echo '</div>'; } // End of the create_form_input() function. // Omit the closing PHP tag to avoid 'headers already sent' errors!

Sorry, the missing bracket is in the script (I just missed it when I copied the code and pasted here). However, I did find the error log whic says: PHP Fatal error: Cannot redeclare create_form_input() previously declared in ---webroot path---/includes/form_functions.inc.php: 13 in ---webroot path---includes/form_functions.inc.php on line 87

Hi daviddawn, Thanks for you quick reply and advice. Here is the code for add_page.php. I was able to follow the tutorial in the book until this point. Then, when I uploaded this file, the form would show up and I cannot see what is wrong. I uploaded it as is from the author's source files: ?php // This page is used by an administrator to create a specific page of HTML content. // This script is created in Chapter 5. // Require the configuration before any PHP code as the configuration controls error reporting: require('./includes/config.inc.php'); // If the user isn't logged in as an administrator, redirect them: redirect_invalid_user('user_admin'); // Require the database connection: require(MYSQL); // Include the header file: $page_title = 'Add a Site Content Page'; include('./includes/header.html'); // For storing errors: $add_page_errors = array(); // Check for a title: if (empty($_POST['title'])) { $t = escape_data(strip_tags($_POST['title']), $dbc); } else { $add_page_errors['title'] = 'Please enter the title!'; } // Check for a category: if (filter_var($_POST['category'], FILTER_VALIDATE_INT, array('min_range' => 1))) { $cat = $_POST['category']; } else { // No category selected. $add_page_errors['category'] = 'Please select a category!'; } // Check for a description: if (!empty($_POST['description'])) { $d = escape_data(strip_tags($_POST['description']), $dbc); } else { $add_page_errors['description'] = 'Please enter the description!'; } // Check for the content: if (!empty($_POST['content'])) { $allowed = '<div><p><span><br><a><img><h1><h2><h3><h4><ul><ol><li><blockquote>'; $c = escape_data(strip_tags($_POST['content'], $allowed), $dbc); } else { $add_page_errors['content'] = 'Please enter the content!'; } if (empty($add_page_errors)) { // If everything's OK. // Add the page to the database: $q = "INSERT INTO pages (categories_id, title, description, content) VALUES ($cat, '$t', '$d', '$c')"; $r = mysqli_query($dbc, $q); if (mysqli_affected_rows($dbc) === 1) { // If it ran OK. // Print a message: echo '<div class="alert alert-success"><h3>The page has been added!</h3></div>'; // Clear $_POST: $_POST = array(); // Send an email to the administrator to let them know new content was added? } else { // If it did not run OK. trigger_error('The page could not be added due to a system error. We apologize for any inconvenience.'); } } // End of $add_page_errors IF. } // End of the main form submission conditional. // Need the form functions script, which defines create_form_input(): require('includes/form_functions.inc.php'); ?> <h1>Add a Site Content Page</h1> <form action="add_page.php" method="post" accept-charset="utf-8"> <fieldset><legend>Fill out the form to add a page of content:</legend> <?php create_form_input('title', 'text', 'Title', $add_page_errors); // Add the category drop down menu: echo '<div class="form-group'; if (array_key_exists('category', $add_page_errors)) echo ' has-error'; echo '"><label for="category" class="control-label">Category</label> <select name="category" class="form-control"> <option>Select One</option>'; // Retrieve all the categories and add to the pull-down menu: $q = "SELECT id, category FROM categories ORDER BY category ASC"; $r = mysqli_query($dbc, $q); while ($row = mysqli_fetch_array($r, MYSQLI_NUM)) { echo "<option value=\"$row[0]\""; // Check for stickyness: if (isset($_POST['category']) && ($_POST['category'] == $row[0]) ) echo ' selected="selected"'; echo ">$row[1]</option>\n"; } echo '</select>'; if (array_key_exists('category', $add_page_errors)) echo '<span class="help-block">' . $add_page_errors['category'] . '</span>'; echo '</div>'; create_form_input('description', 'textarea', 'Description', $add_page_errors); create_form_input('content', 'textarea', 'Content', $add_page_errors); ?> <input type="submit" name="submit_button" value="Add This Page" id="submit_button" class="btn btn-default" /> </fieldset> </form> <?php /* PAGE CONTENT ENDS HERE! */ // Include the footer file to complete the template: include('./includes/footer.html'); ?> Thanks in advance for your help!

Hi, I cannot get add_page.php to display. I am on pages 116 - 132. I used the author's file (rather than create my own) and followed along in the book. I can't figure out what the problem is so I have been stuck on this part for 6 hours. Any advise please? I am on a deadline (yikes). Thanks so much! Zie
