How to return custom error message from controller method validation
to get custom error message you need to pass custom error message on third parameter,like that
$this->validate( $request, ['thing' => 'required'], ['thing.required' => 'this is my custom error message for required']);
For Multiple Field, Role and Field-Role Specific Message
$this->validate( $request, [ 'uEmail' => 'required|unique:members', 'uPassword' => 'required|min:8' ], [ 'uEmail.required' => 'Please Provide Your Email Address For Better Communication, Thank You.', 'uEmail.unique' => 'Sorry, This Email Address Is Already Used By Another User. Please Try With Different One, Thank You.', 'uPassword.required' => 'Password Is Required For Your Information Safety, Thank You.', 'uPassword.min' => 'Password Length Should Be More Than 8 Character Or Digit Or Mix, Thank You.', ] );
https://laravel.com/docs/5.3/validation#working-with-error-messages
$messages = [ 'required' => 'The :attribute field is required.',];$validator = Validator::make($input, $rules, $messages);
"In most cases, you will probably specify your custom messages in a language file instead of passing them directly to the Validator. To do so, add your messages to custom array in the resources/lang/xx/validation.php language file."
