How to display cakephp 2.5.3 model validation message.By default it shows html 5 validation message - html

Question

How to display the validation message which is defined in CakePHP model.When I submit the form , CakePHP model validation works.But validation message for input field is not displayed. It shows HTML 5 validation Message. I want to display CakePHP model validation message. I am using CakePHP 2.5.3
Following is my code block:
Controller:
$this->User->set($this->request->data);
if ($this->User->validates()) {
if ($this->User->save($this->request->data)) {
$Email->send();
$this->Session->setFlash(__('The user has been created'));
if ($this->Auth->login()) {
$this->Session->setFlash(__('Welcome, ' . $this->Auth->user('username')));
$this->redirect($this->Auth->redirectUrl());
}
} else {
$this->Session->setFlash(__('The user could not be created. Please, try again.'));
}
}
Model:
public $validate = array(
'username' => array(
'nonEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'A username is required',
'allowEmpty' => false
),
'unique' => array(
'rule' => array('isUniqueUsername'),
'message' => 'This username is already in use'
),
'alphaNumericDashUnderscore' => array(
'rule' => array('alphaNumericDashUnderscore'),
'message' => 'Username can only be letters, numbers and underscores'
),
)
View:
<div id="divfirstname" class="input text required">
<label for="UserFirstname">First Name <span style="color:#FF0000">*</span></label>
<?php echo $this->Form->text('firstname');?>
</div>
<div id="divlastname" class="input text required">
<label for="UserLastname">Last Name <span style="color:#FF0000">*</span></label>
<?php echo $this->Form->text('lastname');?>
</div>
<div class="input text required">
<label for="UserUsername">Username <span style="color:#FF0000">*</span></label>
<?php echo $this->Form->text('username');?>
</div>

Answer 1

You don't need to wrap the validation-block around your save call.
So this is enough:
if ($this->User->save($this->request->data)) {
$Email->send();
$this->Session->setFlash(__('The user has been created'));
if ($this->Auth->login()) {
$this->Session->setFlash(__('Welcome, ' . $this->Auth->user('username')));
$this->redirect($this->Auth->redirectUrl());
}
} else {
$this->Session->setFlash(__('The user could not be created. Please, try again.'));
}
CakePHP handles automatically the validation when Model->save() is called and displays the error under your input fields. So if $this->save fails because of a validation error, cakephp adds <div class="error-message">Message Text from your model validation array</div> under the right input field.

You are left with 2 options :
Either dont use validation rule in cakePHP which validates on Client side.
On DOM ready , call $("#formId").removeAttr('novalidate'); Like
$(document).ready(function(){
$("#formId").removeAttr('novalidate');
});
