forcing uppercase variable

[dizzie]

hi all...
Hello

I'm adding an offer code to a shopping cart, customers will be sent a code by mail to get 10% off on the checkout
so i have a code set as a variable something like

$offercode = 'WFTP67';

on the form that sends the order the user puts this code in a field, called $offer

I want to make sure that the variables match so i need to force the form feild to send it in uppercase, it shows it in uppercase on the form because of my css, but it doesn't match the code unless i have caps on my keyboard

can this be done easily?
