Forget the previous post for now. I’m now assuming $user_id is in fact an ID number. So something like this should cover the two most important of the four usernames in the database:

function synchro_wp_usermeta($user_id, $password, $meta) {

global $bp, $wpdb;



$fullname = $meta[field_1];

$space = strpos( $fullname, ' ' );



if ( false === $space ) {

$firstname = $fullname;

$lastname = '';

} else {

$firstname = substr( $fullname, 0, $space );

$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );

}



$lowercase = strtolower($fullname);

$autousername = str_replace(' ', '', $lowercase);



update_usermeta( $user_id, 'nickname', $fullname );

update_usermeta( $user_id, 'first_name', $firstname );

update_usermeta( $user_id, 'last_name', $lastname );



$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_login = %s WHERE ID = %d", $autousername, $user_id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_nicename = %s WHERE ID = %d", $autousername, $user_id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $user_id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $user_id ), $user_id ) );

}

add_action( 'wpmu_activate_user', 'synchro_wp_usermeta', 10, 3);

I’ll try that and look into the bp_core_get_user_domain() function after lunch…
