Laravel 11 Client Side Form Validation using JQuery

By Hardik Savani September 4, 2024 Category : Laravel

In this example, I will show you how to add client side form validation using jquery in laravel 11 application.

We must have to implement server side validation, But sometime we need to implement client side validation for user. If you add client side validation then they don't need to submit form and back with validation. So in this example, we will use JQuery form validation JS to add client side validation. we will create simple form with Name, Email, Password and Confirm Password fields. user can fill data and create user. So, let's see the simple example code:

laravel 11 form validation

Step for Laravel 11 JQuery Client Side Validation Example

  • Step 1: Install Laravel 11
  • Step 2: Create Controller
  • Step 3: Create Routes
  • Step 4: Create Blade File
  • Run Laravel App

Step 1: Install Laravel 11

This step is not required; however, if you have not created the Laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Create Controller

In this step, we will create a new `FormController` for adding form validation. In this controller, we will add two methods called `create()` and `store()`. So let's create a new controller using the following command.

php artisan make:controller FormController

Next, let's update the following code in that file.

app/Http/Controllers/FormController.php

<?php
    
namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;
   
class FormController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create(): View
    {
        return view('createUser');
    }
        
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request): RedirectResponse
    {
  
        $validatedData = $request->validate([
                'name' => 'required',
                'password' => 'required|min:5',
                'email' => 'required|email|unique:users'
            ]);
    
        $validatedData['password'] = bcrypt($validatedData['password']);
        $user = User::create($validatedData);
          
        return back()->with('success', 'User created successfully.');
    }
}

Step 3: Create Routes

Furthermore, open `routes/web.php` file and add the routes to manage GET and POST requests for calling views and adding form validation.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\FormController;
  
Route::get('users/create', [ FormController::class, 'create' ]);
Route::post('users/create', [ FormController::class, 'store' ])->name('users.store');

Step 4: Create Blade File

Now, here we will create createUser.blade.php file and here we will create a bootstrap simple form with error validation messages. we will use jquery-validate js file to add client side validation. So, let's create the following file:

resources/views/createUser.blade.php
