title: CakePHP - Empty $this->request->data array after Ajax POST
body: <p>I'm trying to save data which comes from an AJAX POST request in JSON but 
  There is empty <code>$this-&gt;request-&gt;data</code> in controller.</p>
  
  <p>My AJAX call:</p>
  
  <pre><code>$.ajax({
      type: "POST",
      url: 'localhost/pages/register',
      dataType: 'json',
      data: pass_data,
  
  });
  </code></pre>
  
  <p>JSON data:</p>
  
  <pre><code>var email = $("#email").val();  
  var verifyemail = $("#verifyemail").val();  
  var password = $("#password").val();
  var confirm_password = $("#vPassword").val();
  var pass_data = {
      'data[User][email]':email,
      'data[User][verifyemail]':verifyemail,
      'data[User][password]':password,
      'data[User][confirm_password]':confirm_password,
  }
  </code></pre>
  
  <p>I'm use CakePHP 2.3. and jQuery 1.7.</p>
  
  <p>Do you have any ideas?</p>
