Hi! I would need some help to solve a problem on my website.

I want to add a link with php, that became the name of the customer, when he/she login.
I’m writing this code in the pavillion control pannel, but it doesn’t recognize the php code. It only works with html.

text_welcome; else echo $tbData->text_logged; ?>

Could anybody tell me in which line and file, should I add my code to appear in the right side of the top menu?

OC: 2.0.2.0
Pavilion: 1.2.5
