要进行文件上传,我们将使用表单助手。这是文件上传的示例。
更改config / routes.php文件,如以下程序所示。
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。上载的文件将保存在上载/文件夹中。
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上创建目录Files ,然后在该目录下创建一个名为index.php的View文件。将以下代码复制到该文件中。
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:
";
for($i = 2; $i < count($files); $i++)
echo "File is - ".$files[$i]."
";
?>
为用户列出了保存在uploads /文件夹中的文件。通过访问以下URL执行以上示例-
http:// localhost / cakephp4 / fileupload-
当执行上述代码时,您应该看到以下输出-
