如何在 OCMOD 文件中为 opencart 2.3

问题描述

我想在同一文件中的一个脚本块上方添加一小段脚本,并在同一块下添加一个脚本。 (我无法进行替换,因为该块也被另一个扩展修改了)。

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,它会上传正常,因此问题实际上不在于代码ID) 这是我所拥有的:

我曾尝试在同一个操作中使用两次,甚至使用搜索并在一次操作下添加两次,但我遇到了相同的错误

我已将 index="1" 更改为 index="0" 当您使用第二个 add index="1" 时,您将在下一个函数 (public function copyProduct($product_id) {) 中关闭您的条件。我假设您只需要 public function editProduct($product_id,$data) { 的这个例外如果您需要它的第二个功能,您必须单独添加您的条件。
