Form Validation using jQuery in Laravel 8
Step 1 – Install Laravel 8 Application

Step 1 – Install Laravel 8 Application
In step 1, open your terminal and navigate to your local web server directory using the following command:
Then install laravel 8 latest application using the following command:
Step 2 – Configuring Database using Env File
In step 2, open your downloaded laravel 8 app into any text editor. Then find .env file and configure database detail like following:DB_CONNECTION=mysqlDB_HOST=127.0.0.1DB_PORT=3306DB_DATABASE=db nameDB_USERNAME=db user nameDB_PASSWORD=db password
Step 3 – Create Model & Migration File For Product Add Form
In step 3, open command prompt and navigate to your project by using the following command:
Then create model and migration file by using the following command:
The above command will create two files into your laravel 8 form validation application, which is located inside the following locations:
LaraveljQuery/app/Models/Product.php
LaraveljQuery/database/migrations/create_products_table.php
So, find create_products_table.php file inside LaravelForm/database/migrations/ directory. Then open this file and add the following code into function up() on this file: public function up() { Schema::create('products', function (Blueprint $table) { $table->id(); $table->string('title'); $table->string('code'); $table->text('description'); $table->timestamps(); }); }
Now, open again your terminal and type the following command on cmd to create tables into your selected database:
Step 4 – Create Routes
In step 4, open your web.php file, which is located inside routes directory. Then add the following routes into web.php file:<?phpuse Illuminate\Support\Facades\Route;use App\Http\Controllers\ProductController;/*|--------------------------------------------------------------------------| Web Routes|--------------------------------------------------------------------------|| Here is where you can register web routes for your application. These| routes are loaded by the RouteServiceProvider within a group which| contains the "web" middleware group. Now create something great!|*/Route::get('/', function () { return view('welcome');});Route::get('jquery-validation', [ProductController::class, 'index']);Route::post('store-product', [ProductController::class, 'store']);
Step 5 – Creating Controller
In step 5, create form controller by using the following command:
The above command will create ProductController.php file, which is located inside LaraveljQuery/app/Http/Controllers/ directory.
The following laravel validation rules will validate form data on server side in laravel: $validatedData = $request->validate([ 'title' => 'required|unique:posts|max:255', 'code' => 'required|unique:posts|max:255', 'description' => 'required', ]);
So open ProductController.php file and add the following code into it:<?phpnamespace App\Http\Controllers;use Illuminate\Http\Request;use App\Models\Product;class ProductController extends Controller{ public function index() { return view('product'); } public function store(Request $request) { $validatedData = $request->validate([ 'title' => 'required|unique:posts|max:255', 'code' => 'required|unique:posts|max:255', 'description' => 'required', ]); $product = new Product; $product->title = $request->title; $product->code = $request->code; $product->description = $request->description; $product->save(); return redirect('jquery-validation')->with('status', 'Product Has Been Added'); }}
Step 6 – Create Blade File For Product Add Form
In step 6, create new blade view file that named product.blade.php inside resources/views directory for add add product form.
The following code display error message in laravel forms. So do not forget to add the following code along laravel forms fields: @error('title') <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div> @enderror
And the following jQuery code will validate form data on client side or before submit to controller or database:<script> if ($("#product-add").length > 0) { $("#product-add").validate({ rules: { title: { required: true, maxlength: 50 }, code: { required: true, }, description: { required: true, }, }, messages: { title: { required: "Please enter title", }, code: { required: "Please enter valid email", }, description: { required: "Please enter message", }, }, }) } </script>
Don’t worry i have already added the jQuery and server side validation error message display code along with each form fields.
So, you can add the following php and html form code into product.blade.php:<!DOCTYPE html><html><head> <title>Laravel 8 jQuery Validation Example Tutorial</title> <meta name="csrf-token" content="{{ csrf_token() }}"> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"> <script src="//cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.19.0/jquery.validate.min.js"></script> <style> .error{ color: #FF0000; } </style></head><body><div class="container mt-4"> @if(session('status')) <div class="alert alert-success"> {{ session('status') }} </div> @endif <div class="card"> <div class="card-header text-center font-weight-bold"> <h2>Laravel 8 jQuery Form Validation Before Submit</h2> </div> <div class="card-body"> <form name="product-add" id="product-add" method="post" action="{{url('store-product')}}"> @csrf <div class="form-group"> <label for="exampleInputEmail1">Title</label> <input type="text" id="title" name="title" class="@error('title') is-invalid @enderror form-control"> @error('title') <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div> @enderror </div> <div class="form-group"> <label for="exampleInputEmail1">Product Code</label> <input type="text" id="code" name="code" class="@error('code') is-invalid @enderror form-control"> @error('code') <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div> @enderror </div> <div class="form-group"> <label for="exampleInputEmail1">Description</label> <textarea name="description" class="@error('description') is-invalid @enderror form-control"></textarea> @error('description') <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div> @enderror </div> <button type="submit" class="btn btn-primary">Submit</button> </form> </div> </div></div><script> if ($("#product-add").length > 0) { $("#product-add").validate({ rules: { title: { required: true, maxlength: 50 }, code: { required: true, }, description: { required: true, }, }, messages: { title: { required: "Please enter title", }, code: { required: "Please enter valid email", }, description: { required: "Please enter message", }, }, }) } </script></body></html>
