Hi guys,

I want to add a small trick to my BP site, which is to add an activity that contains a user profile field value when a user signs up, it is kind of an introduction.
I tried to add the field value to the new_member activity but it didn’t work, so I thought I could do it like this.

Here’s the code snippet I added to my bp-custom.php, can you please check?

$bp = buddypress();
$bp->activation_complete = true;

function xprofile_bio_field_activity() {
global $bp;
if ( !function_exists( 'bp_activity_add' ) )
return false;

// $user_id = HOW_TO_GET_THE_USER_ID();
$userlink = bp_core_get_userlink( $user_id );

bp_activity_add( array(
'user_id' => $user_id,
'action' => apply_filters( 'xprofile_bio_field_action', sprintf( __( '%s has just registered for this website', 'buddypress' ), $userlink ), $user_id ),
'content' => bp_member_profile_data('field=Bio'),
'component' => 'profile',
'type' => 'new_user_bio'
) );
}

add_action( 'bp_core_activated_user', 'xprofile_bio_field_activity' );

when a user registers now, I get such an activity:
“has just registered for this website 10 seconds ago”

there’s no username, no user avatar and no profile field value as I do not have user_id.

can you please tell me how to get the user_id? and also is this correct or not?

Thank you,
Leo
