Hello community,
I have created an additional field in the activity form with the following code:

add_action ('bp_after_activity_post_form', 'ibdnet_publicar_anonimo'); 
function ibdnet_publicate_anonymous () { 
$ html = '<div class = "checkbox ibdnet-chek-anonymous"> 
<label> 
<input type = "checkbox" name = "ibdnet-chek-anonymous" id = "ibdnet-chek-anonymous" > 
Publish anonymous 
</ label> 
</ div> ';

echo $ html; 
}

and I’m saving the id of the activity in the usermeta table with the following code:

add_action ('bp_activity_posted_update', 'add_anonymous_to_activity', 10, 3); 
function add_anonymous_to_activity ($ content, $ user_id, $ activity_id) {

if ($ _POST ['ibdnet-chek-anonymous']): 
$ anonymous_activity = get_user_meta ($ user_id, 'ibdnet_anonymous_activity'); 
$ anonymous_activity = empty ($ anonymous_activity)? $ activity_id: $ anonymous_activity. ','. $ activity_id; 
update_user_meta ($ user_id, 'ibdnet_anonymous_activity', $ anonymous_activity); 
endif; 
}

How can I make the names of the authors appear as anonymous if they select the field that I created as anonymous if they select the option?

Try with the hook bp_core_get_userlink but it does not work, any idea of ​​how to do it? Thank you.
