CakePHP : Validation message not displaying - php

Question

I'm new to cakePHP and I've made a simple form following some tutorial. On this html form I've used validation. Now the problem is that the validation is working but the message is not displaying what I want it to display. I tried the code below.
Model
public $validate = array(
'title' => array(
'title_required' => array(
'rule' => 'notEmpty',
'message' => 'This is required field'
),
'title_unique' => array(
'rule' => 'isUnique',
'message' => 'This should be unique title'
)
)
);
Controller
public function add() {
if ($this->request->data) {
if ($this->Post->save($this->request->data)) {
$this->Session->setFlash('Post has been added successfully');
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash('Error occured, Please try agan later!');
}
}
}
View
<h2>Add New Post</h2>
<?php
echo $this->Form->create('Post', array('action'=>'add'));
echo $this->Form->input('title');
echo $this->Form->input('body');
echo $this->Form->end('Create Post');
?>
The validation error which I've seen is not the message I mentioned in my controller.

Answer 1

That's built-in browser validation.
Since 2.3 the HTML5 required attribute will also be added to the input based on validation rules.
Your title has the notEmpty rule, so Cake is outputting
<input type="text" required="required" ..
and your browser is triggering that message.
Edit: to override this behaviour, you can do:
$this->Form->input('title', array('required'=>false));
or
$this->Form->submit('Submit', array('formnovalidate' => true));
When you submit the form, your model validation will fire.

Answer 2

From your code what i can see is that you havent included helpers.
public $helpers = array('Html', 'Form', 'Session');
public $components = array('Session');
Just add to your controllers and try..

Answer 3

Your Form-create() options are invalid, first argument is the model-name, second is for options:
<h2>Add New Post</h2>
<?php
echo $this->Form->create('Post', array('action'=>'add'));
echo $this->Form->input('title');
echo $this->Form->input('body');
echo $this->Form->end('Create Post');
?>
If the form-helper does not know which 'model' it is creating a form for, I won't check for field validation in the right place, hence, it won't output the validation errors for 'title'
[update] solution above didn't solve the problem. OP has modified the question
Some ideas:
Be sure to enable 'debug' (App/Config/core.php set Configure::write('debug', 2); Otherwise CakePHP may be using a 'cached' version of your model.
If you've named your Model incorrectly, Cake may be automatically generating a model for you, in which case your own model is never actually used, try this for debugging to see if we even 'get' to your model:
Add this to your model;
public function beforeValidate($options = array())
{
debug($this->data); exit();
}
