In this post example, i will create add blog post form with validation and insert form data to database using laravel 8 version. As well as And validation form data before store into database.

### How to Validate Form Data in Laravel 8

* Step 1 – Install **Laravel 8** Application
* Step 2 – Configuring Database using Env File
* Step 3 – Create Model & Migration File For Form
* Step 4 – Create Routes
* Step 5 – Creating Controller
* Step 6 – Create Blade File For Form

#### Step 1 – Install Laravel 8 Application

In step 1, open your terminal and navigate to your local web server directory using the following command:

```
//for windows user
cd xampp/htdocs

//for ubuntu user
cd var/www/html
```

Then install laravel 8 latest application using the following command:

```
composer create-project --prefer-dist laravel/laravel LaravelFormValidation
```

#### 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 Form

In step 3, open command prompt and navigate to your project by using the following command:

```
cd / LaravelFormValidation
```

Then create model and migration file by using the following command:

```
php artisan make:model Post -m
```

The above command will create two files into your laravel 8 form validation application, which is located inside the following locations:

* LaravelForm/app/Models/Post.php
* LaravelForm/database/migrations/2020\_09\_09\_025857\_create\_posts\_table.php

So, find **create\_posts\_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('posts', function (Blueprint $table) { $table->id(); $table->string('title'); $table->text('description'); $table->timestamps(); }); }

Now, open again your terminal and type the following command on cmd to create tables into your selected database:

```
php artisan migrate
```

#### 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\PostController;/\*|--------------------------------------------------------------------------| 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('add-blog-post-form', \[PostController::class, 'index']);Route::post('store-form', \[PostController::class, 'store']);

#### Step 5 – Creating Controller

In step 5, create form controller by using the following command:

```
php artisan make:controller PostController
```

The above command will create **PostController.php** file, which is located inside **LaravelForm/app/Http/Controllers/** directory.

The following laravel validation rules will validate form data before store into database in laravel: $validatedData = $request->validate(\[ 'title' => 'required|unique:posts|max:255', 'description' => 'required', ]);

So open PostController.php file and add the following code into it:\<?phpnamespace App\Http\Controllers;use Illuminate\Http\Request;use App\Models\Post;class PostController extends Controller{ public function index() { return view('add-blog-post-form'); } public function store(Request $request) { $validatedData = $request->validate(\[ 'title' => 'required|unique:posts|max:255', 'description' => 'required', ]); $post = new Post; $post->title = $request->title; $post->description = $request->description; $post->save(); return redirect('add-blog-post-form')->with('status', 'Blog Post Form Data Has Been inserted'); \}}

#### Step 6 – Create Blade File For Form

In step 6, create new blade view file that named add-blog-post-form.blade.php inside **resources/views directory** for add blog post 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

Don’t worry i have already added the validation error message display code along with each form fields.

So, you can add the following php and html form code into add-blog-post-form.blade.php:\<!DOCTYPE html>\<html>\<head> \<title>How to Validate Form Data in Laravel 8\</title> \<meta name="csrf-token" content="\{{ csrf\_token() \}}"> \<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">\</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 Form Validation Example Tutorial\</h2> \</div> \<div class="card-body"> \<form name="add-blog-post-form" id="add-blog-post-form" method="post" action="\{{url('store-form')\}}"> @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">Description\</label> \<textarea name="description" class="@error('title') is-invalid @enderror form-control">\</textarea> @error('title') \<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>\</body>\</html>

#### Step 7 – Start Development Server

Finally, open your command prompt again and run the following command to start development server for your laravel 8 form application:

```
php artisan serve
```

#### Step 8 – Run Laravel 8 Form Validation App On Browser

In step 8, open your browser and fire the following url into your browser:

```
http://127.0.0.1:8000/add-blog-post-form
```
