我正在使用YII Framework，但是当我更新信息（不包括图像）时，它会抛出图像类型无效的错误，即使我有有效的iamge类型。 它引发错误 请修复以下输入错误： 图像不能为空。 请选择正确的文件格式Yii Image上传无法正常工作更新
public function actionUpdate($id) {
$model = $this->loadModel($id);
$oldImage = $model->image;
if (isset($_POST['Product'])) {
$model->attributes = $_POST['Product'];
$rnd = rand(0, 9999); // generate random number between 0-9999
$uploadedFile = CUploadedFile::getInstance($model, 'image');
if (!empty($uploadedFile)) {
$fileName = "{$rnd}" . time() . "{$uploadedFile}"; // random number + file name
$model->image = $fileName;
$uploadedFile->saveAs(Yii::app()->basePath . '/../images/product/' . $fileName);
@unlink(Yii::app()->basePath . "\\..\\images\\product\\" . $oldImage);
} else {
$model->image = $oldImage;
}
if ($model->save())
$this->redirect(array('view', 'id' => $model->id));
}
$this->render('update', array(
'model' => $model,
));
}
