How can I add a sidebar to the various order form pages?

[userpie]

I'm trying to add a sidebar to my order form pages, but I don't want to modify each template file individually. Is there some kind of container template that I could modify that would affect all order form related pages?

Hello,

 

You could use the following code in your footer.tpl file:

 

{if $filename eq "cart"}

Sidebar HTML goes here

{/if}
