Install Laravel App

First of we need to download laravel fresh setup. Use the below command and download fresh new laravel setup :

composer create-project --prefer-dist laravel/laravel FormValidation

Setup Database

After successfully install laravel 5.7 Application, Go to your project .env file and set up database credential and move next step :

 DB_CONNECTION=mysql 
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=here your database name here
DB_USERNAME=here database username here
DB_PASSWORD=here database password here
Migration

If You will download laravel fresh setup. It has default available CreateUsersTable migration file. Go to app/database/create_users_table.php and put the below code here :

<?php

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

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

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

Next migrate the table using the below command :

php artisan migrate

Now go to app/User.php file and add the fillable of mobile_number like this

protected $fillable = [ 'name', 'email', 'mobile_number', ];

Make Route

We will create two routes in web.php file. Go to app/routes/web.php file and create two below routes here :

 Route::get('form', '[email protected]');
Route::post('save', '[email protected]');

Create Controller

We need to create a controller name FormController. Use the below command and create Controller :

php artisan make:controller FormController

After successfully create controller go to app/controllers/FormController.php and put the below code :

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Validator,Redirect,Response;
use App\User;

class FormController extends Controller
{

    public function index()
    {
    
        return view('form');

    }

    public function save(Request $request)
    {

        request()->validate([
        'name' => 'required',
        'email' => 'required|email|unique:users',
        'mobile_number' => 'required|unique:users'
        ]);

        $data = $request->all();
        $check = User::create($data);

        return Redirect::to("form")->withSuccess('Great! Form successfully submit with validation.');

    }
}

Create Blade view

In this step we need to create blade view file. Go to app/resources/views and create one file name form.blade.php .

<!doctype html>
<html lang="en">
  <head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
  <meta name="csrf-token" content="{{ csrf_token() }}">

      @csrf
      <div class="form-group">

        <input type="text" name="name" class="form-control" id="formGroupExampleInput" placeholder="Please enter name">
        <span class="text-danger">{{ $errors->first('name') }}</span>
      </div>

        <span class="text-danger">{{ $errors->first('password') }}</span>

      </div>
          
      <div class="form-group">
        <label for="formGroupExampleInput2">Mobile Number</label>
        <input type="text" name="mobile_number" class="form-control" id="formGroupExampleInput2" placeholder="Please enter mobile number">
