[Zope] Request data and form data

[Li Dongfeng]

Calling a DTML method/document with
argument is easy, like:

  <A HREF="say_hello?who=<dtml-id>">Say hello</A>

This uses URL link to call a DTML document/method.
But if I use form submit to call, like

<FORM ACTION="say_hello?who=<dtml-id>">
<INPUT TYPE='TEXT' NAME="name" SIZE=20>
<INPUT TYPE='submit'>
</FORM>

then the "say_hello" document will respond with
"Name Error: who not found". It seems that using
form submit cannot transmit request data like "?who=...".
Then how can I supply argument to the responding
DTML document, in addition to the form data?
