Forum OpenACS Q&A: Response to newbie templating question...

The way I would enable similar behaviour with the templating system would be to have an ad_page_contract in your master.tcl file:

ad_page_contract {
} {
  {print_p:notnull,optional f}
}

then at the end of the master.tcl you can ad_return_template with either the printable version or the standard version.

if {[string equal $print_p "t"]} {
  ad_return_template "master-print"
} else {
  ad_return_template "master"
}
