Я пытаюсь remove_filter из этого плагина, так как WordPress refrenceЧто такое имя глобального класса в этом плагине php wordpress?
global $my_class;
remove_filter('the_content', array($my_class, 'class_filter_function'));
В этом коде есть 'add_filter('bp_core_fetch_avatar', array($this, 'set_buddypress_avatar'), 10, 1);', что я хотел бы remove_filter, большая проблема здесь, что $this? Я не могу глобальный $this, так что же такое $my_class в следующем коде?
Я пробовал global $BuddyPress_First_Letter_Avatar и global BuddyPress_First_Letter_Avata, Это дало мне ошибку.
