CakePHP move_uploaded_file 返回 false

Question

我是 CakePHP 新手，正在尝试文件上传，move_uploaded_file 总是返回 false。这是我的代码：

编辑：第一行出了什么问题

// This line was wrong, should be done after uploading.
$this->request->data['Post']['image'] = $this->request->data['Post']['image']['name']


if($this->Post->save($this->request->data)) {
    $filename = basename($this->request->data['Post']['image']['name']);
    $filePath = WWW_ROOT . DS . 'files' . DS . $filename;

    if(move_uploaded_file(
        $this->request->data['Post']['image']['tmp_name'],
        $filePath
    ))
        $this->Session->setFlash(__('Your post has been saved'));

    else
        $this->Session->setFlash(__('Your post has been saved, but image failed'));
}

为什么它不起作用？

//move_uploaded_file() stuff...

$this->request->data['Post']['image'] = $filename;

if($this->Post->save($this->request->data)) { //...
