在主题和插件开发中，我喜欢全面运行所有内容，以确保没有问题，也不会出现任何错误。只有在开发中，我才能在footer.php 要查看正在发生的事情：
if (is_user_logged_in()) :
// GET POST META
// https://developer.wordpress.org/reference/functions/get_post_meta/
global $wp_query;
$post_meta = get_post_meta($post->ID);
echo \'<h1>Post Meta</h1>\';
echo \'<pre>\';
var_dump($post_meta);
echo \'</pre>\';
wp_reset_query();
// SEE WHAT IS ASSIGNED
$queried_object = get_queried_object();
echo \'<h1>Quered Object</h1>\';
echo \'<pre>\';
var_dump($queried_object);
echo \'</pre>\';
wp_reset_query();
endif;
然而，由于我一直在尝试实现更多的设置页面，而不是小部件，所以我想在构建设置页面时测试我得到了什么，这样就不用调用每个设置页面了
get_option(\'whatever\'); 我想转储所有内容，以便查看正在收集的内容以及是否出现任何错误。然而，当我这样做时：
echo \'<h1>Get Options</h1>\';
echo \'<pre>\';
var_dump(get_option());
echo \'</pre>\';
wp_reset_query();
我被抛出了一个错误。当我研究时
get_option() 我没有看到任何关于垃圾场的讨论，而且我在查看时也没有找到解决方案
get-option. 有什么方法可以把所有东西都扔掉吗
get_option()?
编辑：
澄清一下，这在设置页面开发时很有用，那么有没有办法从设置中转储选项？例如：
function wpse_267354() {
add_submenu_page(
\'options-general.php\',
\'Foobar Page\', // $page_title
\'PAGE NAME\', // $menu_title
\'manage_options\', // $capability
\'wpse_267354_slug\', // $menu_slug
\'wpse_267354_function\' // $function
);
}
add_action( \'admin_menu\', \'wpse_267354\' );

您需要一种管理设置的方法。你可以使用任何你认为合适的管理方法。然而，我想出了一个相当“简单”的设置PHP Class, 您可以使用它作为具有属性的对象来检索插件的设置。
对象是插件的设置。对象的属性包含实际设置本身。
很容易进行自定义和扩展。希望这能帮助您更轻松地维护插件和/或主题。

要对此进行自定义，可以根据需要设置每个属性。将属性视为“组名”或“节名”。然后相应调整：
set_default_settings();,
set_user_settings();, 和
set_settings();.
Note: 此类仅处理检索插件设置。此类不处理插件设置的更新。
