failed to send post data from phonegap app to RESTful lib

Question

I'm trying to send data from a phonegap mobile app to my server using $.ajax method I use this code :

var form_data = {parm: 1, token: "2fa7e7e5e76005ffd8bfa5082da9f2f9"};
$.ajax({
    url: "http://example.com/index.php/register_devices/register/format/json",
    type: 'POST',
    data: form_data,
    //dataType:"jsonp",
    success: function(data){
            alert(data);
    },
    error: function(xhr, textStatus, errorThrown){
       alert('request failed: '+ errorThrown);
    }
});
return false;

I also put this line in my config.xml file :

<access origin="*" />

And in the server side I use codeigniter framework with RESTful library like this code :

require(APPPATH.'/libraries/REST_Controller.php');
class Register_devices extends REST_Controller  {
    public function register_post()
    {
        $parm = $this->input->post('parm');
        $token = $this->input->post('token');
        echo $token;
    }
}

when I use GET method it works successfully but the problem is when I use POST method I receive :

"internal server error"

.. Any solve ?

Answer 1

The problem was because this config option :

$config['csrf_protection'] = FALSE;

I just put it FALSE and it works prefect .
