laravel login modification

Laravel is a very popular open source PHP framework that is widely used in web application development. Among them, implementing the user login function is a basic requirement for Web applications. In this article, we will discuss how to modify the login functionality in a Laravel application to meet specific needs or improve user experience.

Modify routing

First, we need to modify the login route. By default, the login route for Laravel applications is /auth/login. However, we may want to change it to some custom path. In Laravel, this can be achieved by modifying the routes/web.php file.

The following is an example to modify the login route from /auth/login to /login:

Route::get('/login', 'AuthLoginController@showLoginForm')->name('login');
Route::post('/login', 'AuthLoginController@login');

Modify the login form view

Next, we can modify the login form view To meet specific needs or improve user experience. In Laravel, the login form view is defined by the resources/views/auth/login.blade.php file.

Here is an example where we add a "Remember Me" checkbox to a form to allow the user to choose whether to stay logged in:

<form method="POST" action="{{ route('login') }}">
    @csrf

    <div class="form-group">
        <label for="email">{{ __('E-Mail Address') }}</label>
        <input id="email" type="email" class="form-control @error('email') is-invalid @enderror" name="email" value="{{ old('email') }}" required autocomplete="email" autofocus>

        @error('email')
            <span class="invalid-feedback" role="alert">
                <strong>{{ $message }}</strong>
            </span>
        @enderror
    </div>

    <div class="form-group">
        <label for="password">{{ __('Password') }}</label>
        <input id="password" type="password" class="form-control @error('password') is-invalid @enderror" name="password" required autocomplete="current-password">

        @error('password')
            <span class="invalid-feedback" role="alert">
                <strong>{{ $message }}</strong>
            </span>
        @enderror
    </div>

    <div class="form-group form-check">
        <input type="checkbox" class="form-check-input" id="remember" name="remember">
        <label class="form-check-label" for="remember">{{ __('Remember Me') }}</label>
    </div>

    <button type="submit" class="btn btn-primary">{{ __('Login') }}</button>
</form>

Modify Login Controller

Finally, we need to modify the login controller to respond to form submission and perform specific actions. In Laravel, the default login controller is app/Http/Controllers/Auth/LoginController.php.

Here is an example where we have added a redirectTo() method to automatically redirect the user to a specific page after successful login:

<?php

namespace AppHttpControllersAuth;

use AppHttpControllersController;
use IlluminateFoundationAuthAuthenticatesUsers;

class LoginController extends Controller
{
    use AuthenticatesUsers;

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

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

    /**
     * Get the post login redirect path.
     *
     * @return string
     */
    public function redirectTo()
    {
        if (auth()->user()->isAdmin()) {
            return '/admin/dashboard';
        }

        return '/dashboard';
    }
}

In the above example, the redirectTo() method is used auth() helper function to check the user role and then redirect to the appropriate page. This provides greater flexibility and scalability to Laravel login functionality.
