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 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>"; ?>
The files saved in uploads/ folder is listed for the user. Execute the above example by visiting the following URL ?
http://localhost/cakephp4/fileupload ?
Output
When you execute the above code, you should see the following output ?

You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.

The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
