php - Structure of $errors with Laravel 4 -

in laravel 4 whenever on every request there variable $errors show errors have happened in request. has structure this:

object(illuminate\support\messagebag)#120 (2) {   ["messages":protected]=>   array(1) {     ["email"]=>     array(1) {       [0]=>       string(40) "the email must valid email address."     }   }   ["format":protected]=>   string(8) ":message" } 

i figured put code on header of app give output user, listing relevant message, this:

@if (count($errors->messages))     <div class="error-box">         <ul>             @foreach ($errors->messages $error)                 <li>{{{ $error }}}</li>             @endforeach         </ul>     </div> @endif 

but apparently cant access messages this.

can please explain me structure of messagebar $errors, , more importantly, how loop through error messages, display them?

you cannot $errors->messages directly because illuminate\support\messagebag has messages property ["messages":protected].

what need use all() this:

@foreach ($errors->all() $error)      <li>{{{ $error }}}</li> @endforeach 

or in fact, since messagebag can behave array, can count() , foreach on directly like:

@if (count($errors)) // or $errors->count()     <div class="error-box">         <ul>             @foreach ($errors $error)                 <li>{{{ $error }}}</li>             @endforeach         </ul>     </div> @endif 

you can see full list of methods can perform laravel's messagebag at:

• laravel 4.1: http://laravel.com/api/4.1/illuminate/support/messagebag.html
• laravel 4.2: http://laravel.com/api/4.2/illuminate/support/messagebag.html
