Can't Get Add_Page To Display Pg. 116-132

[Zie]

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

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!

[daviddawn]

at the very start of the script you are missing an angle bracket ' < ' i dont know whether this was just a mistake in your posting or in the script, is the page throwing back any errors ?

[Zie]

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

[daviddawn]

i think you are including the same file twice, please check lines 13 and 87, also change to require_once rather than include.

[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!

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

[daviddawn]

Glad its working for you buddy, however, line 87  "} // End of the create_form_input() function." is not all one comment, the curly brace is still interpreted by php but the text that follows the forward slash's "//" is read as a comment.
