adding a hidden / pre set field to the register page

Permalink July 10, 2013 at 9:00 AM

I'm trying to add a couple of additional fields to the register page which are hidden and have preset values.

This is what I've got so far:

<input type="hidden" value="<?php echo time(); ?>" name="uName" />
      <input type="hidden" value="mascot" name="akID[<?php echo UserAttributeKey::getByHandle('mascot')->getAttributeKeyID(); ?>][value]" />

The username is working perfectly but the 'mascot' field isn't adding the value to the user.
Can anyone help or tell me what I'm doing wrong?
Thanks in advance.
