@nicola: Thanks a bunch for looking at the code!!! And anyways for your work at bp-dev.org!!!

___

below is the code, it doesn’t work. th error message is:

Warning: Invalid argument supplied for foreach() in ../mu-plugins/ng-who_is_online_2_friends_ver0001.php on line 17

i am getting the feeling the project is way over my head. because i have really no experience in coding my self or on my own. until now i only worked with the given code of word- and buddypress, without diving deeply into php-programing.

therefor i am not even sure if it’s the right way to begin. my thought process was that the friends widget i have is identifying friends by their id’s. so the thing to do is comparing these id’s to those of the users online.

maybe that thought apart is over simplified. otherwise it could just as well be the case that my understanding for php isn’t enough.

possibly the best idea would be to buy a book about php. learn more about it and then begin to build widgets. otherwise it might be not that complicated, if you have the skills.
