Modify existing Authorization module (email to username) - laravel

Question

I would like to modify the existing Authorization module provided by Laravel 5, instead of asking for the email it will ask for the username field in the database.

Answer 1

Laravel search the variable $username in the file :
Illuminate\Foundation\Auth\AuthenticatesUsers
public function loginUsername() {
return property_exists($this, 'username') ? $this->username : 'email';
}
As you can see, by default it will be named as 'email'.
However you can override it in your AuthController by adding :
protected $username = 'username';

Answer 2

You do not need to modify the Auth module to do this, simply pass the user's identifier in the attempt. Use the field name in the attempt array as such:
if (Auth::attempt(['username' => $username, 'password' => $password]))
{
return redirect()->intended('dashboard');
}

Answer 3

You can try to check the file Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers just to get the idea.
Then add an override of postLogin on your AuthController:
public function postLogin(Request $request)
{
$this->validate($request, [
'username' => 'required',
'password' => 'required',
]);
$credentials = $request->only('username', 'password');
if ($this->auth->attempt($credentials, $request->has('remember')))
{
return redirect()->intended($this->redirectPath());
}
return redirect($this->loginPath())
->withInput($request->only('username', 'remember'))
->withErrors([
'username' => 'These credentials do not match our records.',
]);
}
You also need to add use Illuminate\Http\Request; to your AuthController.

Answer 4

you can just override auth username function from LoginController.php in laravel 5.3
public function username(){
return 'username';
}

Answer 5

in controllers\auth\logincontroller add this
protected $username = 'user_name';//user_name field name
then go to Illuminate\Foundation\Auth\AuthenticatesUsers and change
public function username()
{
return 'email';//change this with "return $this->username;"
}
with this method You can have different log in type in different controller for example in another controller controllers\admin_auth\logincontroller
protected $username = 'phone_number';
