laravel 4 returning validation message error

Question

I am currently just testing laravel 4, but i have a problem, in the laravel docs returning error messages is described this way $messages->first('email');should return the message, but no matter what methog id try on the messages i get error

my cobtroller

public function postSignup()
    {
        $rules = array(
            'display_name'     => 'required|unique:users',
        );

        $messages = array(
            'display_name.required' => 'Felhasználónév kötelező',
            'display_name.unique'   => 'Ez a Felhasználónév foglalt',
        );

        $val = Validator::make(Input::all(), $rules, $messages);

        if ($val->passes()) 
        {
            $data = array('msg' => 'yay');
        }
        else
        {
            print_r($messages->first('display_name'));
        }

        return Response::json($data);
    }

{"error":{"type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","message":"Call to a member function first() on a non-object"

if i try with all just for a test print_r($messages->all()); im getting the following

{"error":{"type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","message":"Call to a member function all() on a non-object"

could please someone point out what i am doing wrong?

You may try this

if ($val->passes()) 
{
    $data = array('msg' => 'yay');
}
else
{
    $messages = $validator->messages();
    $data = array('msg' => $messages->first('display_name'));
}
return Response::json($data);

print_r(...); in the controller will print the output outside of the template. On the client side you can check the msg something like this (using jQuery for example)

$.get('url', function(data){
    if(data.msg == 'yay')
    {
        // success
    }
    else
    {
        // failed, so data.msg contains the first error message
    }
});

Validator::make method only accepts two arguments.

No, Validator::make method accepts three arguments. Third one is optional.

You are accessing the messages array you passed into the validator, not the error messages the validator created. Change your code to this:

$val->messages()->first('email')

NOTE: The validator::make method accepts 3 arguments:

/**
 * Create a new Validator instance.
 *
 * @param  array  $data
 * @param  array  $rules
 * @param  array  $messages
 * @return \Illuminate\Validation\Validator
 */
public function make(array $data, array $rules, array $messages = array())
