Laravel 5.8 jQuery Form Validation

In this tutorial you will learn about the Laravel 5.8 jQuery Form Validation and its application with practical example.

Input validation is a process where we check whether the input data provided by user or client is in correct format or not. If the input data fails to satisfy the validation rules then the user is responded with an error response code and the user is requested to resubmit the form with correct information. Generally Form validation is performed at server side, but can be performed at both the server and client side.

In this simple example, I’ll show you how to implement client side validation in laravel using Jquery Form Validation plugin. In this tutorial, you will learn to validate the form data in the client side before it is submitted to server. When the form data satisfies the validation it will submitted to server for further processing.

Create Laravel View Files

In this step, we will create laravel view/blade file to perform display form. Lets create a blade file “index.blade.php” in “resources/views/jqueryFormValidation/” directory and put the following code in it respectively.

resources/views/jqueryFormValidation/contact_form.blade.php

Load JS and CSS file

For that first, we need to load jQuery Form validation plugin along with jQuery to validate input fields and also use bootstrap css file.

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>  
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/js/bootstrap.min.js"></script>  
<script src="https://cdn.jsdelivr.net/jquery.validation/1.16.0/jquery.validate.min.js"></script>

Create Laravel Controller

Next, we have to create a controller to display contact form and to handle form validation and submit operations. Lets Create a controller named ContactController using command given below –

php artisan make:controller jqueryFormValidation/ContactController

1	php artisan make:controller jqueryFormValidation/ContactController

Once the above command executed, it will create a controller file ContactController.php in app/Http/Controllers/jqueryFormValidation directory.

Open the jqueryFormValidation/ContactController.php file and put the following code in it.

app/Http/Controllers/jqueryFormValidation/ContactController.php

<?php

namespace App\Http\Controllers\jqueryFormValidation;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class ContactController extends Controller
{
    public function index()
    {
        return view('jqueryFormValidation.index');
    }       

    public function store(Request $request)
    {  
   		//
    }

}

<?php

namespace App\Http\Controllers\jqueryFormValidation;

use Illuminate\Http\Request;

use App\Http\Controllers\Controller;

class ContactController extends Controller

{

public function index()

{

return view('jqueryFormValidation.index');

}

public function store(Request $request)

{

}

Define Laravel Route

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

Route::get('jquery-form-validation', 'jqueryFormValidation\ContactController@index');

1	Route::get('jquery-form-validation', 'jqueryFormValidation\ContactController@index');

Start Development Server

Now we are ready to run our example so lets start the development server using following artisan command –

php artisan serve

1	php artisan serve

Now, open the following URL in browser to see the output –

http://localhost:8000/jquery-form-validation

Output 1:-

laravel-5-8-jquery-form-validation-1

Output 2:-

Validate form data and display error messages.

laravel-5-8-jquery-form-validation-2
