Missing validation message in cakephp application - php

Question

I'm trying to add a layout for a cakephp application but now my validation message is no longer being displayed. When validating a comment on a blog entry, the validation message thats suppose to be at the top is not displayed.

Answer 1

If you changing the layout means that you missed to add
<?php
if ($this->Session->check('Message.flash')){
echo $this->Session->flash();
}
?>
before the
Other possible place is in the current controller.
Search if you have code like:
$this->Session->setFlash('...');
The first code is responsible for displaying the message, while the second one is responsible for setting the message.
But the code definitely will help more :)

Here is my add function in comments_controller.php
function add(){
debug($this->data);
//if the user submitted a comment post
if (!empty($this->data)){
//display the 'add view'
$this->Comment->create();
if ($this->MathCaptcha->validates($this->data['Comment']['security_code'])) {
if ($this->Comment->save($this->data)){
$this->Session->setFlash(__('The Comment has been added.', true));
$this->redirect('/posts/index/'.$this->data['Comment']['post_id']);
}
//failed validation
else{
debug($this->data);
$this->Session->setFlash(__('Comment could not be saved. Please try again.', true));
}
}
else {
$this->Session->setFlash(__('Please enter the correct answer to the math question.', true));
$this->redirect('/posts/index/'.$this->data['Comment']['post_id']);
}
Here is my entry.ctp where my posts and comments reside:
<div id="article">
<h2><?php echo $entry[0]['Post']['title']; ?></h2>
<p class="date"><em>Modified:</em> <?php $date = new DateTime($entry[0]['Post']['modified']);
echo $date->format('Y-m-d');?></p>
<p class="date"><em>Author:</em> <?php echo $entry[0]['User']['username']; ?></p>
<p class="intro"><?php echo $entry[0]['Post']['content']; ?></p>
<h2>Comments:</h2>
<div id="comments_success"></div>
<!-- show the comment -->
<?php
echo $form->create('Comment', array('action' => 'add'));
echo $form->input('name', array('class' => 'validate[required] text-input'));
echo $form->input('email', array('class' => 'validate[required,custom[email]] text-input'));
echo $form->input('text', array('id' => 'commenttext', 'type' => 'textarea', 'label' => 'Comment:', 'rows' => '10', 'class' => 'validate[required] text-input'));
//captcha
echo $form->input('security_code', array('label' => 'Please Enter the Sum of ' . $mathCaptcha));
echo $form->input( 'Comment.post_id', array( 'value' => $entry[0]['Post']['id'] , 'type' => 'hidden') );
echo $form->end('Submit');
?>
<!-- comments -->
<ol>
<?php
foreach ($entry[0]['Comment'] as $comment) :
?>
<li>
<h3><?php echo $comment['name']; ?></h3>
<p class="date"><em>Date:</em> <?php echo $comment['created']; ?></p>
<p class="text"> <?php echo $comment['text']; ?></p>
</li>
<?php
endforeach;
?>
</ol>
</div>
This is the index function in my posts_controller
function index($entry_id = null) {
if (isset($entry_id)){
$entry = $this->Post->findAllById($entry_id);
$comments = $this->Post->Comment->getCommentsFromPostID($entry_id);
$this->set('entry' , $entry);
$this->set('mathCaptcha', $this->MathCaptcha->generateEquation());
$this->render('entry');
}
else{
$posts = $this->Post->find('all');
$this->set(compact('posts'));
}
}

I know this is old, but ust make sure you have the following code somewhere visible in your app/views/layouts/default.ctp (or whatever is your layout for this application)
<?php echo $this->Session->flash(); ?>
It will echo nothing if there is no message to be displayed, but if there is a message, then it will be output accordingly.
