To work on file upload we are going to use the form helper. Here, is an example for file upload.
Make Changes in the config/routes.php file, as shown in the following program.
<?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']); $builder->fallbacks(); });
Create a FilesController.php file at src/Controller/FilesController.php. Copy the following code in the controller file. Ignore, if already created.
Create uploads/ directory in src/. The files uploaded will be saved in uploads/ folder.
<?php namespace App\Controller; use App\Controller\AppController; use Cake\View\Helper\FormHelper; class FilesController extends AppController { public function index(){ if ($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.
<?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>"; ?>
The files saved in uploads/ folder is listed for the user. Execute the above example by visiting the following URL −
http://localhost/cakephp4/fileupload −
When you execute the above code, you should see the following output −
