CakePHP:保存数据时出错

所以我在用CakePHP保存数据时遇到了问题

如果我上传一个图像（意味着['PictureForm']['file']['name']存在），一切正常，数据被保存。但是，如果['PictureForm']['file']['name']为空，并且['PictureForm']['url']存在，则映像已正确保存在磁盘上，但$this->PictureForm->save（$this->data）失败

有人看到我的代码有任何明显的错误吗

if (isset($this->data['PictureForm'])) {
                            ///////////////////////////////////////////////////////DEV
                            if(!$this->data['PictureForm']['file']['name']) {
                                    if (!$this->data['PictureForm']['url']) {
                                            $this->Session->setFlash('Error: no image URL or file given!');
                                            $this->redirect(array('action' => '/'));
                                    } else {
                                            $fileExtension = getExtension($this->data['PictureForm']['url']);
                                            $this->request->data['PictureForm']['filename'] = randFilename() . "." . $fileExtension;

                                    }
                            } else { //file was uploaded
                                    $fileExtension = getExtension($this->data['PictureForm']['file']['name']);
                                    if (!$fileExtension) {

                            }

                                    $this->Session->setFlash('Picture <a href="/spootur/media/p/' . $this->data['PictureForm']['filename'] . '">saved</a>');
                                    $this->redirect(array('action' => 'p/' . $this->data['PictureForm']['filename']));
                            } else {
                                    $this->Session->setFlash('Error: could not save to db' . $this->data['PictureForm']['filename']);

}

如果保存失败，请在else块中尝试查看验证错误，而不是重定向：

if ($this->PictureForm->save($this->data)) {
    // code
} else{
    debug($this->PictureForm->validationErrors);
}

直接将代码粘贴到问题中，不要链接到网站外。这使得回答起来更容易，也便于以后阅读的人。好的，谢谢。我从来都不知道如何使用debug（），所以这肯定会派上用场。
