为了进行文件上传,我们将使用表单助手。这是文件上传的示例。
在 config/routes.php 文件中进行更改,如以下程序所示。
<?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']); $builder->fallbacks(); });
在 src/Controller/FilesController.php 创建 FilesController.php 文件。 将以下代码复制到控制器文件中。如果已经创建,请忽略。
在 src/ 中创建 uploads/ 目录。上传的文件将保存在 uploads/ 文件夹中。
<?php namespace App\Controller; use App\Controller\AppController; use Cake\View\Helper\FormHelper; class FilesController extends AppController { public function index(){ if ($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); } } } ?>
在 src/Template 处创建一个目录 Files 并在该目录下创建一个 View 文件,名为 index.php。 复制以下代码位于该文件中。
<?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>"; ?>
为用户列出保存在 uploads/ 文件夹中的文件。通过访问以下 URL 来执行上述示例 -
http://localhost/cakephp4/fileupload -
当您执行上述代码时,您应该看到以下输出 -
