我需要更改一个主题组件的模板中的一个字符串。可以说这是在header.php中。在我的孩子主题中，我创建了一个header.php文件来覆盖父母的主题header.php。Wordpress儿童主题非常小变化
我的问题是我在header.php中写什么？我是否复制粘贴父母版本中的所有内容并更改字符串？如果'是'，那么我如何确保我得到更新，因为现在和将来我都会使用这个版本的header.php，因为它总是会覆盖父版本。如果“不”比我做什么？其中一个文件只是一个模板，但我必须在hook.php文件中做一个小的字符串更改......我该如何处理？
示例：这是来自父母主题的示例文件。我想改变的是“阅读更多”到“更多更好”。

所以孩子的主题工作流程是：我创建一个header.php文件，并把它放在相同的相对路径。我复制原始header.php的内容，更改文本并保存。当主题得到更新时，我比较我的header.php和新的。如果有我再次手动复制粘贴应用修改？ – mp3por
