我想在一个脚本块上方添加一小段脚本，在同一文件的同一块下添加另一个脚本。（我无法进行替换，因为该块也被另一个扩展修改）。

如果我有两次相同的文件，我会在安装扩展程序时收到消息“修改需要唯一的 ID 代码”（请注意，如果我删除其中一个文件部分，它会正常上传，因此问题实际上与代码 ID 无关）在这里是我所拥有的：

我曾尝试在同一操作中使用两次，甚至使用搜索并在一次操作下添加两次，但我得到了同样的错误：

我已更改index="1"为index="0" 当您使用第二个添加index="1"时，您在下一个函数（public function copyProduct($product_id) {）中关闭您的条件。我假设你需要这个例外，public function editProduct($product_id, $data) {如果你需要它用于第二个功能，你必须单独添加你的条件。
