How add a custom field to Laravel 5.4 default login controller.

In this php example (app/Http/Controllers/Auth/LoginController.php) my model is called Client and the custom field for login validation is status. (Client->status)

Add in your resources/lang/en/auth.php file :

    'failed_status' => 'Your account is inactive yet. Please confirm your e-mail address.',

Feel free to customize!

LoginController.php

<?php

namespace App\Http\Controllers\Auth;

use App\Client;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest', ['except' => 'logout']);
    }

    /**
     * Handle a login request to the application.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\RedirectResponse|\Illuminate\Http\Response
     */
    public function login(Request $request)
    {
        $this->validateLogin($request);

        // If the class is using the ThrottlesLogins trait, we can automatically throttle
        // the login attempts for this application. We'll key this by the username and
        // the IP address of the client making these requests into this application.
        if ($this->hasTooManyLoginAttempts($request)) {
            $this->fireLockoutEvent($request);

            return $this->sendLockoutResponse($request);
        }

        // Customization: Validate if client status is active (1)
        if ($this->attemptLogin($request)) {
            return $this->sendLoginResponse($request);
        }

        // Customization: Validate if client status is active (1)
        $email = $request->get($this->username());
        // Customization: It's assumed that email field should be an unique field 
        $client = Client::where($this->username(), $email)->first();

        // If the login attempt was unsuccessful we will increment the number of attempts
        // to login and redirect the user back to the login form. Of course, when this
        // user surpasses their maximum number of attempts they will get locked out.
        $this->incrementLoginAttempts($request);

        // Customization: If client status is inactive (0) return failed_status error.
        if ($client->status === 0) {
            return $this->sendFailedLoginResponse($request, 'auth.failed_status');
        }

        return $this->sendFailedLoginResponse($request);
    }

    /**
     * Get the needed authorization credentials from the request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    protected function credentials(Request $request)
    {
        $credentials = $request->only($this->username(), 'password');
        // Customization: validate if client status is active (1)
        $credentials['status'] = 1;
        return $credentials;
    }

    /**
     * Get the failed login response instance.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  string  $field
     * @return \Illuminate\Http\RedirectResponse
     */
    protected function sendFailedLoginResponse(Request $request, $trans = 'auth.failed')
    {
        $errors = [$this->username() => trans($trans)];

        if ($request->expectsJson()) {
            return response()->json($errors, 422);
        }

        return redirect()->back()
            ->withInput($request->only($this->username(), 'remember'))
            ->withErrors($errors);
    }
}

Thanks this worked for me but, I had to change few things
($client->status === 0) to ($client->status == 0) and there is a need to check for the existence of the user before comparing
if($client){ if ($client->status == 0) { return $this->sendFailedLoginResponse($request, 'auth.failed_status'); } }
without this it will throw an error if the email or username does not exist in the database.

Awesome, Thanks

good ... its work!

App\Client not found

If email is not exist the its not working

good! Awesome, Thanks !

good! Awesome,
I'll try it in my production site.
Thanks !

Thanks you !

For laravel 5.5 above use
throw ValidationException::withMessages([ $this->username() => [trans('auth.failed_status')], ]);

You're The Best , Many Thanks For Your Efforts

@webtamizhan
For Laravel 5.5 or above use

`protected function sendFailedLoginResponse(Request $request, $trans = 'auth.failed')

{

    throw ValidationException::withMessages([ $this->username() => [trans($trans)], ]);

}`
