CakePHP - File upload | Adglob Infosystem Pvt Ltd

To work on file upload in cakePHP we are going to use the form helper. Here, is an example for file upload of cakephp.

Example

Make Changes in the config/routes.php file, as shown in the following program.

config/routes.php

<?php
use Cake\Http\Middleware\CsrfProtectionMiddleware;
use Cake\Routing\Route\DashedRoute;
use Cake\Routing\RouteBuilder;
$routes->setRouteClass(DashedRoute::class);
$routes->scope('/', function (RouteBuilder $builder) {
   $builder->registerMiddleware('csrf', new CsrfProtectionMiddleware([
      'httpOnly' => true,
   ]));
   $builder->applyMiddleware('csrf');
   //$builder->connect('/pages',['controller'=>'Pages','action'=>'display', 'home']);
   $builder->connect('fileupload',['controller'=>'Files','action'=>'index']);
   $builder->fallbacks();
});

Create a FilesController.php file at src/Controller/FilesController.php. Copy the following code in the controller file. Ignore, if already created.

Create uploads/ directory in src/. The files uploaded will be saved in uploads/ folder.

src/Controller/FilesController.php

<?php
   namespace App\Controller;
   use App\Controller\AppController;
   use Cake\View\Helper\FormHelper;
   class FilesController extends AppController {
      public function index(){
         if ($this->request->is('post')) {
            $fileobject = $this->request->getData('submittedfile');
            $uploadPath = '../uploads/';
            $destination = $uploadPath.$fileobject->getClientFilename();
            // Existing files with the same name will be replaced.
            $fileobject->moveTo($destination);
         }
      }
   }
?>

Create a directory Files at src/Template and under that directory create a View file called index.php. Copy the following code in that file.

src/Template/Files/index.php

<?php
   echo $this->Form->create(NULL, ['type' => 'file']);
   echo $this->l;Form->file('submittedfile');
   echo $this->Form->button('Submit');
   echo $this->Form->end();
   $uploadPath ='../uploads/';
   $files = scandir($uploadPath, 0);
   echo "Files uploaded in uploads/ are:<br/>";
   for($i = 2; $i < count($files); $i++)
      echo "File is - ".$files[$i]."<br>";
?>
