Thank you -- based on all of your input I'm having another stab at
using T2.
Two more questions:
- How do you pass variables to T2-enabled pages without breaking T2
behaviors? For instance, I have a page where person X buys product P;
prod_id is passed as a var or an arg in the query string. The T2 form
shows person X's details, including an inline image (very nice ;-)),
but the #zoom anchor doesn't work because the prod_id in the URL gets
in the way. What's the best practice here?? I can sneak prod_id into
the session vars, but that doesn't seem very RESTful -- apart from it
being a pain not being able to embed the prod_id in a link...
- Call me stupid, I can't find the way to rename the submit button on
T2 update/create forms? I know you can do this with submit_button= in
SQLFORM, but this doesn't seem to get passed into T2 forms. The only
way is to manipulate the components[..] stuff -- eg, through the new
elements interface?
Cheers again...
