Hi, With check markup I was wondering if there was any way of passing additional data through to the php filter. What I would like to do is in E-Commerce I would like to turn the emails into filtered fields, so you can use php to really make you email look really good. The problem is that most of the time I will not know what the transaction is, and would like to pass it. Also is it possible to have a filter that is allowed only in certain situations as I would like to turn all the ecommerce emails into filtered fields, but this does not really relate to a node at all. I did think of changing it so that I can have a subroutine like drupal_set_title() which I can call and set the current transaction and then I can get the transaction if I need it. Thanks for any assistance. Gordon.
