Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Controller

Open project into terminal and run this command.

$ php artisan make:controller DataController

It will create a DataController.php file inside /app/Http/Controllers folder.

Open DataController.php file and write this code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class DataController extends Controller
{
    public function index()
    {
        return view("form");
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function formSubmit(Request $request)
    {
        $request->validate([
            'photo' => 'required',
        ]);

        if ($request->hasFile('photo')) {

            dd($request->photo);
        }
    }
}

Concept

if ($request->hasFile('photo')) {
