Allow login using username or email in Laravel 5.4

Question

Now I've followed the Laravel documentation on how to allow usernames during authentication, but it takes away the ability to use the email. I want to allow users to use their username or email to login. How do I go about this?

I've added this code to the LoginController as per Laravel's Documentation and it only allows username for login. I want it to accept username or email for login.

public function username () {     return 'username'; } 

Answer 1

I think a simpler way is to just override the username method in LoginController:

public function username() {    $login = request()->input('login');    $field = filter_var($login, FILTER_VALIDATE_EMAIL) ? 'email' : 'username';    request()->merge([$field => $login]);    return $field; }

Follow instructions from this link: https://laravel.com/docs/5.4/authentication#authenticating-users

Then you can check for the user input like this

$username = $request->username; //the input field has name='username' in form  if(filter_var($username, FILTER_VALIDATE_EMAIL)) {     //user sent their email      Auth::attempt(['email' => $username, 'password' => $password]); } else {     //they sent their username instead      Auth::attempt(['username' => $username, 'password' => $password]); }  //was any of those correct ? if ( Auth::check() ) {     //send them where they are going      return redirect()->intended('dashboard'); }  //Nope, something wrong during authentication  return redirect()->back()->withErrors([     'credentials' => 'Please, check your credentials' ]); 

This is just a sample. THere are countless various approaches you can take to accomplish the same.
