We all are know files upload is a very important part in any web application. because most of application has required files uploading functionality. in this article we will see how to done it and also see some laravel files uploading validation like max file size, min file size, file type, etc...

Just follow the below steps and you can easily upload multiple files with validation in laravel application:

• Step - 1 : Create Laravel Fresh New Project
• Step - 2 : Setup Database Credentials
• Step - 3 : Create Migration & Model
• Step - 4 : Create Route
• Step - 5 : Create Controller
• Step - 6 : Create Blade View

Step - 1 : Create Laravel fresh New Project

First, we need to create one fresh laravel application help of composet command. just run the following command in your terminal and create one laravel application.

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

Step - 2 : Configure Database Setting.

Now, into the second step we should configure database setting in .env file just open your .env file and make the following changes. set youe database name, username and password.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=databasename
DB_USERNAME=root
DB_PASSWORD=root	

Step - 3 : Create Migration & Model

Now, we need to create migration for transactions table. run the following command in your terminal.

php artisan make:migration create_documents

After run this command, then open that created file which will created on database/migrations folder. just open it and put the following code into that migration file.

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateDocuments extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('documents', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('file');
            $table->timestamps();
        });
    }
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('documents');
    }
}	

Next, run the php artisan migrate command in the terminal for create documents table.

After, run the migration then we need to create Document model for store files data. run the following command in the terminal for create model.

php artisan make:model Document
    

Now open the app/Document.php file and write the following code into it.

namespace App;
use Illuminate\Database\Eloquent\Model;
class Document extends Model
{
    protected $table = 'documents';
    protected $guarded = array();
    public function storeData($input)
    {
        return static::create($input);
    }
}
    

Step - 4 : Create Routes

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

Route::get('document', '[email protected]')->name('document');
Route::post('documentstore', '[email protected]')->name('documentstore');
	

Step - 5 : Create Controller

Now, we need to create DocumentController.php file in app\Http\Controllers folder. just run the following command in your terminal and create your controller.

php artisan make:controller DocumentController

Just, open your DocumentController.php file and write the following code into this controller.

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Validator,Redirect,Response,File;
Use App\Document;
class DocumentController extends Controller
{
    public function index()
    {
        return view('document');
    }
    public function store(Request $request)
    {
        request()->validate([
            'file' => 'required',
            'file.*' => 'mimes:doc,pdf,docx,txt,zip,jpeg,jpg,png'
        ]);
        if($request->hasfile('file')) { 
            foreach($request->file('file') as $file)
            {
                $fileName = time().rand(0, 1000).pathinfo($file->getClientOriginalName(), PATHINFO_FILENAME);
                $fileName = $fileName.'.'.$file->getClientOriginalExtension();
                $file->move(public_path(),$fileName);
                $input['file'] = $filename;
                Document::create($input);
            }
        }         
        \Session::put('success', 'Document will be uploaded.');
        return redirect()->route('document'); 
    }
}   
    

Step - 6 : Create Blade View

Now, the last step we need to create one simple HTML blade file in resources/views/document.blade.php file and write the following code into it.

<html lang="en" class="">
<head>
<meta charset="UTF-8">

                    <strong>{{ $message }}</strong> 
                </div>
            @endif 
            @if (count($errors) > 0)
                <div class="alert alert-danger">
                    <strong>Whoops!</strong> There were some problems with your input.<br><br>
                    <ul>
                        @foreach ($errors->all() as $error)
                            <li>{{ $error }}</li>
                        @endforeach
                    </ul>
                </div>
            @endif 
            <form action="{{ route('documentstore') }}" method="post" enctype="multipart/form-data">
                @csrf
                <div class="form-group">
                    <input type="file" class="form-control-file" name="file[]" multiple>                   
                </div>
                <button type="submit" class="btn btn-primary">Submit</button>
            </form> 
         </div>
     </div>
