get_term 或 get_term_by 不起作用 - 我在分类法之外，也不在 single.php 内

检查此 link 关于 ACF 插件选项。 https://www.advancedcustomfields.com/resources/get_field/

此示例显示了各种 $post_id 值，以从 post、用户、术语和选项中获取值。

$post_id = false; // current post
$post_id = 1; // post ID = 1
$post_id = "user_2"; // user ID = 2
$post_id = "category_3"; // category term ID = 3
$post_id = "event_4"; // event (custom taxonomy) term ID = 4
$post_id = "option"; // options page
$post_id = "options"; // same as above

$value = get_field( 'my_field', $post_id );
