[Plugin: ALO EasyMail Newsletter] EasyMail Newsletter multi-site compatibility fix

Hi,

I am currently testing this plugin on a WP3.0 multi-site installation. Apart from the fact that the plugin seems to need to create new database tables, it appears to function fine.

Except…

One big NO when in multi-site mode is the following issue. The plugin allows import from registered users. Nice feature but when WP is in multi-site mode the plugin takes ALL registered users, including those that are registered to other sites in the network!

I suggest the following patch to prevent this. Tested on WP 3.0.2 in multi-site mode but should work on regular mode too :

Change the function starting on line 688 of alo-easymail_functions.php from

function ALO_em_get_recipients_registered () {
	global $wpdb;
	return $wpdb->get_results( "SELECT ID AS UID, user_email FROM $wpdb->users" );
}

to

function ALO_em_get_recipients_registered() {
	$wp_user_search = new WP_User_Search();
	foreach ( $wp_user_search->get_results() as $reg_user )
		$reg_users[] = (object) array_merge( array('UID' => $reg_user), (array) get_userdata($reg_user) );
	return $reg_users;
}
