When are you wanting things to be deleted?  If you're just doing general cleanup, you'll need to create a PHP file, include engine/start.php, and then call that function with the proper GUIDs of objects for which you want the river items to be removed.

Yeah, just general cleanup, so if i add this to my new php file:

function remove_from_river_by_object($object_guid) {
// Sanitise
$object_guid = (int) $object_guid;
// Load config
global $CONFIG;
// Remove
return delete_data("delete from {$CONFIG->dbprefix}river where object_guid = {$object_guid}");


and call that file in the riverdashboard start file...how can i call it?

this remove_from_river_by_object ( $ object_guid ) will remove definitle the entry for everybody right ? is there something for remove from river but only for the user who remove it ?

A bit like facebook, exemple i see an entry on the river, i remove it with a remove button for exemple but other user them still have this entry, is that possible ? is there something like that in elgg ?

Yes, what we're referring to above will delete all activity, I'm interested in the function your speaking of as well. 

Anyone have any clues or insight?

+1 for a delete from river button..

anyone know the code for this? a plugin even?

This is a good idea, and I have always wanted to bring up thr topic.. Sometime the whole column is filled with repeated update (profile/icon) of a single person. Both user and admin must have the Delete option.

esto es lo que yo e tratado de decir pero no encontré una ayuda.

el the wire si tiene un botón eliminar e copiado su código pero no a funcionado alguna solución ?
