CakePHP 文件上传

为了处理文件上传,我们将使用表单助手。这是一个文件上传示例。

示例

在config/routes.php文件中进行修改,如下程序所示。

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();
});

src/Controller/FilesController.php 中创建一个 FilesController.php 文件。 将以下代码复制到控制器文件中。忽略(如果已创建)。

在 src/中创建 uploads/目录。上传的文件将保存在uploads/文件夹中。

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);
         }
      }
   }
?>

src/Template 中创建一个目录 Files,然后在该目录下创建一个名为 index.php 的 View 文件。 b> 在该文件中复制以下代码。

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>";
?>

为用户列出了保存在uploads/文件夹中的文件。通过访问以下 URL 执行上述示例:

http://localhost/cakephp4/fileupload:

输出

当你执行上面的代码时,你应该看到下面的输出:
