This is the function that the regular wpmu registration process uses to add the user to wp_usermeta:

function update_usermeta( $user_id, $meta_key, $meta_value ) {

global $wpdb;

if ( !is_numeric( $user_id ) )

return false;

$meta_key = preg_replace('|[^a-z0-9_]|i', '', $meta_key);



/** @todo Might need fix because usermeta data is assumed to be already escaped */

if ( is_string($meta_value) )

$meta_value = stripslashes($meta_value);

$meta_value = maybe_serialize($meta_value);



if (empty($meta_value)) {

return delete_usermeta($user_id, $meta_key);

}



$cur = $wpdb->get_row( $wpdb->prepare("SELECT * FROM $wpdb->usermeta WHERE user_id = %d AND meta_key = %s", $user_id, $meta_key) );

if ( !$cur )

$wpdb->insert($wpdb->usermeta, compact('user_id', 'meta_key', 'meta_value') );

else if ( $cur->meta_value != $meta_value )

$wpdb->update($wpdb->usermeta, compact('meta_value'), compact('user_id', 'meta_key') );

else

return false;



wp_cache_delete($user_id, 'users');



return true;

}

Is this function also used by Buddypress or does Buddypress replace it with something else?

Where do meta_key and meta_value come from? Data from Buddypress xprofile field_1 is not included at this point…

What would happen if I just added $bp as global? Trying that now… EDIT: Does nothing.

I see xprofile_sync_wp_profile() uses this same function….
