Hi.
The output of the form is supposed to be a value to pass to a filter
specified in my mapfile.
Actually, I think I am close to the solution, but I also think I
misunderstood the way I am supposed to do what I need.
Basically, the output of the form should replace the value '%vitigni%'
in the string:
FILTER ('[vitigni]' = '%vitigni%') # MAPFILE
I also forgot to mention I am doing everything with openlayers, so I
think I should use ol API rather than ms templating.
Am I on the right track?
Actually, by my last tests I got something positive by specifying the
'params' option using ol's " ol.source.ImageWMS"
(http://openlayers.org/en/latest/apidoc/ol.source.ImageWMS.html).
The thing I need I guess is to get user choice from the form and pass it
in the filter updating the 'params' option (using the "updateParams()"
method?, see
http://openlayers.org/en/latest/apidoc/ol.source.ImageWMS.html#updateParams).
Do you think this is correct?
Sorry for messing up a bit but it's really new stuff for me...

The error you're getting is because no mode is set. That's the output from the
form supposed to be? If it's just the resulting map then add a hidden variable
called mode with a value of map. The filter and validation look ok to me.

Subject: [mapserver-users] R: understanding runtime substitution usage
I tried that but that did not do the trick.
I removed it from the HTML, but I keep it in the mapfile (as if I remove it
it does not work anymore).
So, what I am trying to do is showing my WMS filtered with the value
specified in the form.
From what I've read in the docs
(http://www.mapserver.org/cgi/runsub.html#filters), VALIDATION is also
mandatory from version 6 onward, so I've included it.
I simplified my testcase to this:
mapfile
LAYER
NAME zone
...
FILTER ('[vitigni]' = '%vitigni%')
VALIDATION
"vitigni" "^[a-zA-Z\-]+$"
END
END
Form
<form name="mapserv" method="GET"
action="http://localhost/cgi-bin/mapserver/mapserv.exe?";>
<input type="hidden" name="map"
value="//nbgis01/mapserver/umbe/mapfile/test10_runtimesubstitution.map">
<select name="vitigni">
<option value="Groppello"> Groppello
</option>
</select>
<br><br>
<input type="submit" value="Click Me">
</form>
When I click "Click Me" I receive:
mapserv(): Web application error. Traditional BROWSE mode requires a
TEMPLATE in the WEB section, but none was provided.
And the URL looks like (obviously wrong):
http://localhost/cgi-bin/mapserver/mapserv.exe?map=%2F%2Fnbgis01%2Fmapserver
%2Fumbe%2Fmapfile%2Ftest10_runtimesubstitution.map&vitigni=Groppello

Try to remove the brackets from the parameter name
<select name="[vitigni]">
should be
<select name="vitigni">
