Hide mt_rand

Hi

I'm a noob and I know this will be a stupid question to many of you but I am desperate.

I aneed to append a random number to a name to keep it unique, however I do not want the number to be displayed. The code below is what I am trying but It doesn't seem to work. Could some one please give any tip/s?

The code I am using so far is:

$userData['userName'] = type="hidden" value="<?php echo mt_rand(100000, 999999) $this->trimUserName($user->get('name'));


Any help on this would be really appreciated


thanks in advance

kind reagrds
