Laravel 5.5 validator

Question

Is there a way in laravel on how I can choose an email that is stored in the database?

For example, if I want a unique email, you use "unique:users" like this:

$validator = Validator::make($request->all(), [
        'email' => 'required|unique:users',
        'password' => 'required'
        ]);

But what I want to know is if it can check if the given email is stored in the database or not. Is it possible to do this with the validator?

Answer 1

If you want to be sure it doesn't exist in DB, use the unique rule:

unique:table

If you want to be sure the record exists in DB, use the exists rule:

exists:table

Answer 2

You can use exists ( https://laravel.com/docs/5.5/validation#rule-exists ) key word as :

$validator = Validator::make($request->all(), [
    'email' => 'required|unique:users|exists:users',
    'password' => 'required'
]);

Or you can do something like that :

$validator = Validator::make($request->all(), [
    'email' => 'required|unique:users',
    'password' => 'required'
]);

if ($validator->fails()) {
    echo 'That email address is already registered';
}
