Angular and CodeIgniter Validation Library

Question

I'm trying to us CodeIgniter's validation library on json data posted from Angularjs. The problem is when I go to set the validation rule the json object is not recognized as a post value by Codeigniter. Anybody know how to set a Codeigniter validation rule for a json object?

    $data = json_decode(file_get_contents("php://input"));
    //die($data->name); = "Bob"
    $this->form_validation->set_rules($data->name, 'Name', 'trim|required|min_length[3]');
       if($this->form_validation->run() == FALSE) { 
          $this->output->set_output(validation_errors()); 
       }

If Angular sends the data by POST, they should be available. Try var_dump($_POST) to see if there's anything in there (maybe it's malformed?).

If not, you can try this "hack":

 $_POST = json_decode(file_get_contents("php://input"), true);

before your validation.

So, do something like:

$_POST = json_decode(file_get_contents("php://input"), true);
$this->form_validation->set_rules($data->name, 'Name', 'trim|required|min_length[3]');
if(!$this->form_validation->run()) { 
   $this->output->set_output(validation_errors()); 
}
