Currently the automatic forum subscription on course purchase works at a Forums level only and not at topic level.
Also, note that for courses running for several months might have a lot of topics and it would not be useful for a new student to get automatically subscribed to all the topics in the forum. So unfortunately we can not add this request in the main product.
But if you want a specific fix for your site then we can share a code fix/tip which would enable this feature for you.
sure,please share code to fix,thanks.
Please try adding the given code in your wplms-customizer.php file in wplms customizer plugin :
add_action('wplms_front_end_save_course_components','course_forum_instrcutor_subscription',10,2);
function course_forum_instrcutor_subscription($course_id,$settings){
$user_id=get_current_user_id();
if(!empty($settings[1]->id) && $settings[1]->id=='vibe_forum'){
bbp_add_user_forum_subscription( $user_id, $settings[1]->value);
}
}
It will auto-subscribe instructor to course forum as soon as instructor save components .
