Validation errors in AJAX mode

Question

Currently I use this to display validation errors via ajax:

            if (data.validation_failed == 1)
            {
                var arr = data.errors;
            


        

Answer 1

The easiest way is to leverage the MessageBag object of the validator. This can be done like this:

// Setup the validator
$rules = array('username' => 'required|email', 'password' => 'required');
$validator = Validator::make(Input::all(), $rules);

// Validate the input and return correct response
if ($validator->fails())
{
    return Response::json(array(
        'success' => false,
        'errors' => $validator->getMessageBag()->toArray()

    ), 400); // 400 being the HTTP code for an invalid request.
}
return Response::json(array('success' => true), 200);

This would give you a JSON response like this:

{
    "success": false,
    "errors": {
        "username": [
            "The username field is required."
        ],
        "password": [
            "The password field is required."
        ]
    }
}
