CakePHP - File upload

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

Example

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

config/routes.php

<?php
use CakeHttpMiddlewareCsrfProtectionMiddleware;
use CakeRoutingRouteDashedRoute;
use CakeRoutingRouteBuilder;
$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 AppController;
   use AppControllerAppController;
   use CakeViewHelperFormHelper;
   class FilesController extends AppController {
      pubpc function index(){
         if ($this->request->is( post )) {
            $fileobject = $this->request->getData( submittedfile );
            $uploadPath =  ../uploads/ ;
            $destination = $uploadPath.$fileobject->getCpentFilename();
            // 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-&gtl;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 psted for the user. Execute the above example by visiting the following URL −
