Question

I create a function in CakePHP controller class to process AJAX request. But I found different result when using CakePHP function and simple (Non-MVC) PHP code. My problem is when it goes to submit() process. When using CakePHP function it returns blank page.

Here is the AJAX request code that I use:

var userdata = {username : $("#UserUsername").val()};
        $.ajax({
            type:'POST',
            url: 'http://localhost/mycakephp/users/login',
            data: userdata,                     
            success: function(data){                                    
                if(data==0){
                    alert("empty");                 
                } else {
                    $("#UserLoginForm").submit();                       
                }
            }               
        });     

But when I pointed the url to external site like this:

url: ‘http://localhost/test/test.php’

Which test.php is a simple PHP code to handle request, submit process works fine.

According to your comment, if you use the SecurityComponent, you could disable POST validation on the login action. In your UsersController, add this:

function beforeFilter()
{
    parent :: beforeFilter();

    switch($this->request->params['action'])
    {
        case 'login':
            $this->Security->validatePost = false;
            $this->Security->csrfCheck    = false;
            break;
    }
}

But off course you loose the value added by the SecurityComponent on the login action.
