我几乎完成了一个成功的第一次插件，但不幸的是，我无法将更新后的值提交到我在register_activationhook上创建的数组中。
我需要一些关于Wordpress如何处理所有脏活的见解——或者$_POST会是更好的方法吗？
下面你会看到我的admin.php，它处理所有与管理相关的东西。

非常欢迎对替代方法的反馈！
我提前感谢大家，祝大家度过美好的一天！：）
我有更新功能clsc_html_page()，并添加了操作'admin_init'来保存和注册您的设置字段。

您可以在使用表单时继续使用POST方法，因此在提交时使用update_option更新选项值
参考URL:
https://codex.wordpress.org/Function_Reference/update_option
如何使用update_option:
function my_option_function() {
update_option('option_value','none');
}
add_action('update_option', 'my_option_function'); ?>
