[Zope] subpath in dtml?

[Dylan Reinhardt]

I don't think there's a "keep-it-simple" answer that will let you use 
http://something.com/reg/b6ac3fe9  the way you want to..

In Zope, the URL  somesite/foo/bar  means "use bar in the context of foo," 
_not_ "pass bar to foo"

In typical usage, bar is a _method_ of foo or is _contained by_ foo.

Since what you want to do is to pass an arbitrary value to a specific 
object, the very most straightforward ways would be to roll them up in the 
URL, use POST, or put the value in a cookie.

Thus, you can try:

<form action=reg method=post>
<input type=hidden name=my_id value=<dtml-var some_value>>
<input type=submit value="Finish Registration">
</form>

Or:

<dtml-call "RESPONSE.setCookie('my_id', some_value)">

Either one will allow you can catch my_id in reg thus:

<dtml-var my_id>

and your URL will be the ultra-nice  http://something.com/reg

That's about it for uncomplicated solutions.  You *could* write a 
registration product that trapped unbound methods and used them as passed 
values... but not only did you say you didn't want to write a product, I'm 
not sure it would be such a great idea to do something like that anyway.  :-)

HTH,

Dylan
