Brent,
Yes, it's great!
If memory serves, it's as easy as putting this in the rest of your
template form:
<INPUT TYPE="HIDDEN" NAME="trip" VALUE="[trip]">
Only issue is you might want an initialization value at startup,
which you could pass in as a GET parameter in the page opening link.

gidday,
I have a mapfile picking up a parameter from the html from a select
list, to
choose a value in an Postgis SQL to restrict the returned values.
If I zoom,
however, I lose the value.
Is there any way to pass an html variable to the html template to
"remember"
the selected member in the select list (without having to resort to
mapscript)?
ie: HTML select returns trip=tan0601
mapfile data statement has:
select the_geom from (select * from stations where trip="%trip%")
as myquery
using unique oid using SRID=4326
This works perfectly, and displays just the selected data but when
I zoom,
the selection is lost. Is there any way I can set up the mapfile &
html
template to retain the selected value?
Thanks,
Brent Wood
