damn it – badly formated the code – try this:

<?php
/*
Plugin Name: XProfile to username
Plugin URI: http://
Description: Created for a specific project, this plugin copies a field from the user's Xprofile to their username, ensuring first that it is unique by adding a  digit to te end
Version: 0.1

*/

function xprofile_to_username($xp) {
	global $wpdb;

	$field_id = BP_XProfile_Field::get_id_from_name('Name/Company Name');
	if(!$field_id || $xp==null) {
		return;
	}
	if($field_id == $xp->field_id) { // cover me, I'm going in
		$new_username=strtolower(preg_replace('/[^\w\d]/','-', $xp->value));
		$existing_user_by_that_username=get_user_by('login', $new_username);
		if($existing_user_by_that_username && ($existing_user_by_that_username->ID !== $xp->user_id )) { // another user already has that login
			$i=1;
			while(get_user_by('login', $new_username."-$i")) {
				$i+=1;
			}
			$new_username.="-$i";
		}
		$wpdb->update($wpdb->users, array('user_login' => $new_username), array('ID' => $xp->user_id));
		return;
	}	
}
add_action('xprofile_data_after_save','xprofile_to_username');

?>

Well I have a plugin – except that I can’t be arsed to release it as a plugin at the moment so I’ll just cut&paste the code here.

2 things:
1. it doesn’t replace the wp-email-login plugin or the login for hack above – it adds to them by simply forcing the username to be the same a field pulled from the Xprofile.
2. It’s hardwired to a specific field name in @applegateian’s project. You’ll need to edit the code to use your own field name because, like I say, I haven’t got time to turn it into a proper plugin. When I find the enthusiasm to do it properly I’ll create a plugin settings menu and stuff.

<?php

/*

Plugin Name: XProfile to username

Plugin URI: http://

function xprofile_to_username($xp) {

global $wpdb;

$field_id = BP_XProfile_Field::get_id_from_name(‘Name/Company Name’);

	if(!$field_id || $xp==null) {

return;

	}

if($field_id == $xp->field_id) { // cover me, I’m going in

		$new_username=strtolower(preg_replace('/[^\w\d]/','-', $xp->value));

$existing_user_by_that_username=get_user_by(‘login’, $new_username);

		if($existing_user_by_that_username && ($existing_user_by_that_username->ID !== $xp->user_id )) { // another user already has that login

$i=1;

			while(get_user_by('login', $new_username."-$i")) {

$i+=1;

			}

$new_username.=”-$i”;

		}

$wpdb->update($wpdb->users, array(‘user_login’ => $new_username), array(‘ID’ => $xp->user_id));

		return;

}

}

add_action(‘xprofile_data_after_save’,’xprofile_to_username’);

?>

Just put this is a file called xprofile-to-username.php in a folder called xprofile-to-username, activate it and Bob’s your uncle. Every time the user’s profile gets updated, their username will mirror the xprofile field (with hyphen instead of funny characters and numbers to remove any duplicates).

Enjoy.
