Question

我在wordpress主题的function.php文件中进行了更改。当我尝试更新funtion.php文件时，它会出错：

致命错误：在第45行的/hermes/waloraweb088/b1248/moo.armaan815/Voga/fp/wp-content/themes/enterweb/functions.php中调用未定义的函数add_action（）。

我不确定如何修复它。我真的很感激反馈/帮助。感谢。

这是function.php文件代码。行号“45”表示侧栏功能后的第一个呼叫。

Answer 1

我已将这个functions.php代码复制到测试环境中，并且无法产生相同的错误（唯一的问题是在开始时缺少打开的php标记。

作为一个稍微单独的注释，我会使用'widgets_init'钩子将侧边栏注册添加到他们自己的函数中。像

这样的东西

add_action('widgets_init','register_my_sidebars');

您不需要测试register_sidebar是否存在。关于该主题的This is a good article。
