CakePHP login function for ajax call - cakephp

Question

So here is situation:
I'm using Js helper to create ajax login form in CakePHP and this is placed in my view:
<?php
$data = $this->Js->get('#UserLoginForm')->serializeForm(array('isForm' => true, 'inline' => true));
$this->Js->get('#UserLoginForm')->event(
'submit',
$this->Js->request(
array ('controller' => 'users', 'action' => 'login'),
array (
'update' => '#messagediv',
'before' => '$("#loading").fadeIn()',
'complete' => '$("#loading").fadeOut()',
'data' => $data,
'async' => true,
'dataExpression'=>true,
'method' => 'POST',
)
)
);
?>
Then below this I have my form included and below form I have:
<?php echo $this->Form->create('User');
echo $this->Form->input('username');
echo $this->Form->input('password');
echo $this->Form->end('submit);
?>
<?php echo $this->Js->writeBuffer(); ?>
Now I don't know how to make proper function in controller to check for login and redirect if successfull or display error if not..
I was able to make something that check for login and echo 1 if login deatils are correct and echo 0 if not but whenever I try to use redirect in controller function it just load "whole login page" in div #messagediv...
This is how my controller action looks now:
public function login() {
if ($this->request->isAjax()) {
$this->layout = 'ajax';
if ($this->Auth->login()) {
$this->Session->setFlash('Login Successfull');
} else {
$this->Session->setFlash('Login Incorrect');
}
}
}
Can anyone tell me what I'm doing wrong?
So how to redirect after login successfull and how to output error message to #messagediv if wrong username or pw?

Answer 1

If I understand correctly what you're trying to do (load only the flash message and not the whole page), change your action like this:
public function login() {
if ($this->request->isAjax()) {
$this->layout = 'ajax';
if ($this->Auth->login()) {
$this->Session->setFlash('Login Successfull');
$this->redirect('wherever');
} else {
$this->Session->setFlash('Login Incorrect');
$this->render('messagediv');
}
}
}
Then create a View at View/Users/messagediv.ctp that only contains echo $this->Session->flash();
There might be other ways of doing this that might be better, though I'm not sure depending on your exact use for it. This should solve what you're trying to do (if I'm not mistaken).

Try adding RequestHandler to your $components array.
var $components = array("RequestHandler");
