Answer by Can Celik for Login only if user is active using Laravel

You don't have to override the whole function. You can just change the Validator in AuthController to achieve that adding "exists:table,column" validation.

Let's assume that you have a users table with email,password and active fields.

'email' =>'exists:users,email,active,1'

Here is the validotor function should look like in AuthController.php

protected function validator(array $data){    return Validator::make($data, ['email' => 'required|email|max:255|exists:users,email,active,1','password' => 'required|confirmed'    ]);}

or if you are using soft deletes this should work too.

'email' =>'exists:users,email,deleted_at,NULL'

You can also check out the validation rule at this link http://laravel.com/docs/5.1/validation#rule-exists
