#laravel

Originally posted @ https://codeanddeploy.com visit and download the sample code: https://codeanddeploy.com/blog/laravel/laravel-8-form-validation-example

In this post, I will show you an example of how to implement a Laravel 8 form validation. W know that this is one of the most important to implement before storing or updating records from your Laravel 8 application. So that we saved a record that is clean and secured to our database. For more information about Laravel validation and their supported rules kindly visit their official documentation.

Below is the step-by-step process on how to implement Laravel validation.

Step 1: Laravel Installation

Before we start we need to install the Laravel 8 application in our local environment. In this example, I'm using XAMPP via Windows. But you're free to use any machine and OS.

In your HTDOCS folder run this command:

composer create-project laravel/laravel laravel-validation --prefer-dist
Enter fullscreen mode Exit fullscreen mode

Once done above command run the below command to point our Laravel 8 project directory.

cd laravel-valdation
Enter fullscreen mode Exit fullscreen mode

Step 2: Database Configuration

If your Laravel project is fresh then you need to update your database credentials. Just open the .env file in your Laravel 8 project.

.env

DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=your_database_name_here DB_USERNAME=your_database_username_here
Enter fullscreen mode Exit fullscreen mode

Step 3: Generate Model, Controller, and Migration

To generate model, controller, and migration for our Laravel ajax example kindly run the following command:

php artisan make:model Project -m -c
Enter fullscreen mode Exit fullscreen mode

Step 4: Migration Setup

Let's set up the migration of our projects table see below example code:

<?php use Illuminate\Database\Migrations\Migration; use Illuminate\Database\Schema\Blueprint; use Illuminate\Support\Facades\Schema; class CreateProjectsTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create('projects', function (Blueprint $table) { $table->id(); $table->string('title'); $table->string('description'); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists('projects'); } }
Enter fullscreen mode Exit fullscreen mode

Now let's run the following command below:

php artisan migrate
Enter fullscreen mode Exit fullscreen mode

Step 5: Setup Model

Here is the code of our project.php model.

<?php namespace App\Models; use Illuminate\Database\Eloquent\Factories\HasFactory; use Illuminate\Database\Eloquent\Model; class Project extends Model { use HasFactory; protected $fillable = [ 'title', 'description' ]; }
Enter fullscreen mode Exit fullscreen mode

Step 6: Setup Controller

Below is the code of our ProjectController.php as you can see we are using Response when responding to the successful request.

<?php namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Models\Project; use Response; class ProjectController extends Controller { /** * Display a listing of the resource. * */ public function index() { $projects = Project::orderBy('id','desc')->get(); return view('projects.index')->with(compact('projects')); } /** * Show the application dashboard. * * @return \Illuminate\Http\Response */ public function create() { return view('projects.create'); } /** * Store a newly created resource in storage. * */ public function store(Request $request) { $data = $request->validate([ 'title' => 'required|max:70', 'description' => 'required' ]); $project = Project::create($data); return redirect('projects')->with('success', 'Project created successfully.'); } }
Enter fullscreen mode Exit fullscreen mode

Step 7: Setup Routes

Now let's code our routes.php see the whole code below.

<?php use Illuminate\Support\Facades\Route; use App\Http\Controllers\ProjectController; /* |-------------------------------------------------------------------------- | 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('/', [ProjectController::class, 'index']); Route::resource('projects', ProjectController::class);
Enter fullscreen mode Exit fullscreen mode

Step 8: Create Project Layout

Below we create a new folder inside resources/views then create a projects folder. Then create index.blade.php and create.blade.php.

index.blade.php

Enter fullscreen mode Exit fullscreen mode

create.blade.php
