Laravel is arguably the most used and popular PHP Framework for Web Artisans.
Laravel has its own in-built functionality for Auth (User Registration and Login). If you think you feel satisfied with the in-built functionality, you can make use of it and your application will work well. But, if you want to go further to have your own custom Auth function, this article is for you. Let's get started!
In this article, I will be showing you how you can write custom login form validation and authentication without reloading the browser.
STEP 1: Create Users
I want to assume you already have users created in your users database table.
STEP 2: Create Login Page
This our our short code for our login page view
<body>
<div class="col-lg-4 col-md-4">
<form action="{{ route('login') }}" method="POST" id="login_form"
class="request-form ">
@csrf
<h2>Login</h2>
<div id="show_error" style="color: red"> </div>
<div class="form-group mr-2">
<label for="" class="label">Email</label>
<input type="email" name="email" class="form-control" >
<span class="text-danger error-text email_error"
style="color: red"></span>
</div>
<div class="form-group mr-2">
<label for="" class="label">Password</label>
<input type="password" name="password" class="form-control"
>
<span class="text-danger error-text password_error"
style="color: red"></span>
</div>
<div class="form-group">
<input type="submit" value="Login" class="btn py-3 px-4"
style="background-color: #5f76e8; color:#ffffff">
</div>
</form>
</div>
//add javascript with ajax here
<script src="[place you jquery source here...]"></script>
<script>
$("#login_form").submit(function(e){
e.preventDefault();
var all = $(this).serialize();
$.ajax({
url: $(this).attr('action'),
type: "POST",
data: all,
beforeSend:function(){
$(document).find('span.error-text').text('');
},
//validate form with ajax. This will be communicating
with your LoginController
success: function(data){
if (data.status==0) {
$.each(data.error, function(prefix, val){
$('span.'+prefix+'_error').text(val[0]);
});
}
// redirect the user to [another page] if the
login cred are correct. Remember this is
communicating with the LoginController which we
are yet to create
if(data == 1){
window.location.replace(
'{{route("dashboard.index")}}'
);
}else if(data == 2){
// Show the user authentication error if the
login cred are invalid. Remember this is
communicating with the LoginController which we
are yet to create
$("#show_error").hide().html("Invalid login
details");
}
}
})
});
</script>
</body>
Login View Sample : login.blade.php
NOTE: You can customize this to your desire
STEP 3: Create LoginController
Open your command prompt interface, cd to your project
directory and paste the below command there
php artisan make:controller LoginController
namespace App\Http\Controllers;
use Illuminate\Support\Facades\Auth;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Session;
use Illuminate\Support\Facades\Validator;
class LoginController extends Controller{
public function login(Request $request){
$validator = Validator::make($request->all(), [
'email' => 'required',
'password' => 'required',
]);
// validate all requests and it sends output to your
login.blade.php
if(!$validator->passes()){
return response()->json([
'status'=>0,
'error'=>$validator->errors()->toArray()
]);
}
$user_cred = $request->only('email', 'password');
if (Auth::attempt($user_cred)) {
//if user is logged in and the role is user
if(Auth()->user()->role=='user'){
return response()->json([ [1] ]);
}
}else{
//if user isn't logged in
return response()->json([ [2] ]);
}
return redirect("/");
}
}
STEP 4: Modify your route:web.php
add your controller to your web.php; as the case maybe
Route::post('/login'[App\Http\Controllers\LoginController::class, 'login'])->name('/login');
Hello friends, in this article we successfully created a login form with Laravel and AJAX without reloading the browser. I hope you enjoy it.
