Modify existing Authorization module (email to username)

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

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

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';

Answer 5

you can just override auth username function from LoginController.php in laravel 5.3

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