Laravel 8.0 Form Validation Example

Hello Artisan,

Today we will make form validation strategies to make input data validated.

Our final output looks like 

"laravel form validation before submit" "laravel custom validation" "laravel custom validation error messages" "laravel validation rules list" "laravel email validation" "laravel api validation" "laravel email validation regex" "image validation in laravel"

Create a Laravel Project first, run this command

composer create-project –prefer-dist laravel/laravel blog

Make databse Connection , create a database in the Mysql database after that go to the .env file and set the values,

Make Database Connection

and add the code to .env file
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_blog
DB_USERNAME=root
DB_PASSWORD=

Create your custom route,

routes/web.php
Route::get('user/create',[UserController::class,'create']);
Route::post('user/store',[UserController::class,'store']);

After creating a brand new laravel project you have already the User model and UserController in your project directory. If not then add

Create Model

Models/User.php
<?php

namespace App\Models;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable
{
    use HasFactory, Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
}

Create Controller

app/Http/controllers/UserController.php
<?php

namespace App\Http\Controllers;

use App\Models\User;
use Illuminate\Http\Request;

class UserController extends Controller
{

    public function create(){
        return view('user.create_user');
    }
    public function store(Request $request){

//        dd($request);

        $validatedData = $request->validate([
            'name' => 'required',
            'password' => 'required|min:5',
            'email' => 'required|email|unique:users'
        ], [
            'name.required' => 'User Name is required',
            'password.required' => 'User Password is required'
        ]);

        $validatedData['password'] = bcrypt($validatedData['password']);
        $user = User::create($validatedData);

        return back()->with('success', 'User created successfully.');

    }
}

Also you have migration file, if not then add

database/migrations/2014_10_12_000000_create_users_table.php
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('users');
    }
}

Run Migrate command to Create table to the database

php artisan migrate

Create your view
