[mapserver-users] R: understanding runtime substitution usage

[Lime, Steve D (MNIT)]

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. --Steve

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">
