Cakephp图片上传

Question

我正在使用cakephp Qimage组件进行图片上传。

public  function img_uploads(){
    $data['file']= $this->request->data['Basicprofile']['photo'];
    $data['path']= WWW_ROOT . 'img/uploads/teachers/';
    unset($this->request->data['Basicprofile']['photo']);
    $this->request->data['Basicprofile']['photo']=$this->Qimage->copy($data);
}

// Qimage复制功能

public function copy($data){

    // Verify file and path
    if (!isset($data['file']) || !isset($data['path']) || !is_array($data['file'])){
        $this->errors[] = 'Name or path not found!';
        return false;
    }

    if (!is_writable($data['path'])){
        $this->errors[] = 'Destination path is not writable!';
        return false;
    }

    if (!$this->_verifyMime($data['file']['name'])){
        $this->errors[] = 'The file must be an jpg, gif or png image!';
        return false;
    }

    // Generate filename and move file to destination path
    $filename_array = explode('.', $data['file']['name']);
    $ext = end($filename_array);
    $ext = strtolower($ext);
    $name = uniqid() . date('dmYHis') . '.' . $ext;
    $complete_path = $data['path'] . DIRECTORY_SEPARATOR . $name;

    if (!move_uploaded_file($data['file']['tmp_name'], $data['path'] . $name)){
        $this->errors[] = 'Error while upload the image!';
        return false;
    }

    // Return image filename
    return $name;
}

问题是路径不可写。我给了777上传文件夹的权限。静止图像无法上传。有什么建议吗？
