How to validate passwords with Laravel 5.1

Question

I would like to validate a password so that it meets the following:

• is at least 8 characters long
• contains at least 1 uppercase letter
• contains at least 1 lowercase letter
• contains at least 1 special character
• matches a confirmation field

Currently i have:

$validator = \Validator::make($request, [
    'password' => 'min:8|confirmed'
],[
    'password.confirmed' => 'Both `password` and `password_confirmation` are required',
    'password.min' => 'The password must contain at least 8 characters'
]);

This will take care of the min length and the confirmation but i can find a good way to do the other check. Any help will be appreciated.

Answer 1

I think you can use a regex to do the trick: http://laravel.com/docs/5.1/validation#rule-regex

You can use like this:

['password' => ['regex:^(?=.{8,})(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=!?]).*$']]

Hope it helps in someway!

Try this it works :)

   $rules = array(
        'username' => 'required',
        'email' => 'required | between:5,100 | email ',
        'password' => 'required | confirmed |regex:/^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*()+]+.*)[0-9a-zA-Z\w!@#$%^&*()+]{8,}$/'
    );

    $input = Input::all();

    $validation = Validator::make($input, $rules);

    if ($validation->fails()){
        //if validation fails redirect with inputs
        return redirect()->route('/')->withInput()
            ->withErrors($validation);
    }
