[Zope-DB] Reference DTML-sqlvar in ZPT?
Dear list, I have a ZPT that lists results from a Z SQL Method. It has one argument: dropdown-department. Everything works fine, except I cannot find a way to include the passed SQL argument as a string in the ZPT document! To explain it in another way, a user selects a value from a drop-down list. This value is passed to a Z SQL Method. My ZPT displays these results, and I need to include the passed value (DTML-sqlvar) in a heading in the ZPT. Any help would be much appreciated.

All I want to do is use the dtml-sqlvar argument as a string in my ZPT. My ZPT is simply a report containing the results of the SQL query; I need to use the argument as a title for the page.

Re: [Zope-DB] Reference DTML-sqlvar in ZPT?
I guess my questions are confusing since I am new to Zope. The dtml-sqlvar is already defined; the results from the Z SQL Method are already presented; I just want to remind the user of what they passed to the Z SQL Method. In other words, I only want to print what they selected from a drop-down list and passed to the Z SQL Method. I just want to print an already defined variable. The problem is: how to print a dtml-sqlvar in ZPT? I tried p tal:replace=dtml-sqlvar/dropdown-selectiondropdown-selection goes here/p Which did not work.

SQL Method.
You can't get sql query parameters from it's results. It's like calling
a function. You pass some parameters to it and get results...

I think you're looking at this from the wrong side ;)
When you submit a form that contains your select list, then you have
chosen option at REQUEST object. You may get this with:
context.REQUEST.get('name-of-your-parameter')
and pass it into PageTemplate with results.
For example (may be buggy):
Your form with selection list (PageTemplate):
form action=results.html
select name=my_item
option value=1blablabal1/option
option value=2blablabal2/option
/select
/form
results.html (ScriptPython):
my_item = context.REQUEST.get('my_item')
results = context.mySQL(my_item=my_item)
return context.resultPageTemplate(my_item=my_item, results=results)
resultPageTemplate (PageTemplate):
div tal:define=myitem python: options.get('my_item', 0);
results python: options.get('results', 0)
You've chosen: span tal:replace=my_item/span
div tal:repeat=item results tal:content=item/name/div
/div
