How to redirect back to previous page after login success?

Use-

return redirect()
        ->back();

Normally, after successfully logged in, the best way to redirect to protected page is intended().

in the LoginController.php there is a line of code that control this login success redirect protected $redirectTo = '/home';

where should I put this into? what is file name?

return redirect()
        ->back();

and this one, where should I put it? what is the file name?

return redirect()->intended('defaultpage');

Go to Login Controller and update this code-

if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return redirect()->back();
}

Hi I have watch this video from Laravel 5.4 From Scratch (But Jeffrey didn't really teach about it)

• Rapid Authentication and Configuration
• Associating With Users
• Associating With Users: Part 2

(I use Lav 5.4) I have check my LoginController.php, but i can't find this line of code

if (Auth::attempt(['email' => $email, 'password' => $password])) {

and I simply put your code to my LoginController.php and it crashed

My LoginController.php

<?php

namespace App\Http\Controllers\Auth;

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

class LoginController extends Controller
{
    use AuthenticatesUsers;
    
    protected $redirectTo = '/home';
    
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    protected function credentials(Request $request) {
        return $request->only($this->username(), 'password') + ['verified' => true];
    }
}

@tisuchi Little tip, these do the same thing :)

return back();

// same as

return redirect()->back();

Hi tisuchi, any help man? I still can't figure it out

Go to app/Http/Controllers/Auth/AuthController.php.

You will get something like this-

<?php
namespace App\Http\Controllers\Auth;
use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;
class AuthController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Registration & Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users, as well as the
    | authentication of existing users. By default, this controller uses
    | a simple trait to add these behaviors. Why don't you explore it?
    |
    */
    use AuthenticatesAndRegistersUsers, ThrottlesLogins;
    /**
     * Where to redirect users after login / registration.
     *
     * @var string
     */
    protected $redirectTo = '/';

Now, in this last line of my code, you can see-

    protected $redirectTo = '/';

Here, you can change where ever you want to redirect after successfully login. It can be like this-

protected $redirectTo =  'your-url';

protected $redirectTo =  'your-url';

Yes, I understand that line of code but the problem is that code is static, you can only redirect back to your predifined url It can't redirect back to previous page

and I found this solution by Scott Byers, but it is not working too

Laravel >= 5.3 The Auth changes in 5.3 make implementation of this a little easier, and slightly different than 5.2 since the Auth Middleware has been moved to the service container. Modify the new Middleware auth redirector

/app/Http/Middleware/RedirectIfAuthenticated.php

Change the handle function slightly, so it looks like:

public function handle($request, Closure $next, $guard = null)
{
    if (Auth::guard($guard)->check()) {
        return redirect()->intended('/home');
    }

    return $next($request);
}

(Solution) I managed to solve it (but I'm not that sure if this is the correct way to do it) in the AuthenticatesUsers.php file

    /**
     * The user has been authenticated.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  mixed  $user
     * @return mixed
     */
    protected function authenticated(Request $request, $user)
    {
        return back(); //add this line of code
    }

and btw I found this RedirectsUsers.php file, but I have no idea how it work so I don't touch it

<?php

namespace Illuminate\Foundation\Auth;

trait RedirectsUsers
{
    /**
     * Get the post register / login redirect path.
     *
     * @return string
     */
    public function redirectPath()
    {
        if (method_exists($this, 'redirectTo')) {
            return $this->redirectTo();
        }

        return property_exists($this, 'redirectTo') ? $this->redirectTo : '/';
    }
}
