Validation request with Laravel 5 - validation

Question

I am trying to make validation with Laravel 5 on right way:
Here is my working code in model:
public function apiAddNewComment() {
if (Input::get("task") == 'addComment') {
$user = Auth::id();
$inputs = array(
'comment' => Input::get('comment'),
'projectID' => Input::get('projectID'),
'order' => Input::get("order"),
'level' => Input::get("level"),
);
$rules = array(
'comment' => 'required|between:15,600',
'projectID' => "required|exists:project_group,project_id,user_id,$user|numeric",
'order' => "required|numeric",
'level' => "required|numeric"
);
$validator = Validator::make($inputs, $rules);
if ($validator->fails()) {
return json_encode(array('err' => true, 'errors' => $validator->messages()->all()));
} else {
return $this->createNewComment();
}
}
}
here is my controller:
public function update($id, Comment $update)
{
return $update->apiUpdateComment();
}
How can I make validation with request?
And can someone explain me how this method works inside request:
public function authorize()
{
return false;
}
?

Answer 1

The Request has to basic functions: rules() and authorize()
rules returns an array that is used for the validation.
The authorize method can for example check if the user is allowed to do this request.
public function authorize() {
return Auth::check();
}
So you don't have to check it each time when you use the request in a controller.
If you need no check just return true.
UPDATE:
Generate a request File with artisan
php artisan make:request CommandRequest
then edit the generate file like this:
class CommandRequest extends FormRequest
{
public function rules()
{
return [
'comment' => 'required|between:15,600',
'projectID' => "required|exists:project_group,project_id,user_id,$user|numeric",
'order' => "required|numeric",
'level' => "required|numeric"
];
}
public function authorize()
{
return true;
}
}
Also update the controller method:
public function update($id, Comment $update, CommandRequest $request)
{
// create your comment here like:
return Comment::create($request->all());
}

You are using a Laravel 4 code I guess, you need to translate it to L5 where Input::get('var') turns into $request->input('var') for instance:
public function apiAddNewComment(Illuminate\Http\Request $request) { //Remember to add the Request as a parameter of the method
if ($request->input("task") == 'addComment') {
...
Then the validation part looks fine
