[mapserver-users] using &viewparams

[Rahkonen Jukka]

Hi,

I guess that you are mixing two great software by trying to use the Geoserver "viewparams" vendor option with Mapserver. Instead, with Mapserver you will need to use the run-time substitution system. Read for example http://mapserver.org/cgi/runsub.html#runsub and http://linfiniti.com/2011/09/making-the-most-of-umn-mapserver-runtime-variable-substitution/.

You are almost there but you must add validation for your "id" parameter and use &id=1 syntax in the WMS requests.

In my mapfile I have one layer called streets. The streets are stored in postgis database and in my mapfile I have that:

".... DATA "the_geom from streets using unique id WHERE id = %id% .. "

Next, i have added to the URL GetMap request this:

&viewparams=id:1


But I get all the layer, and not only the feature with id 1...

I'm doing something wrong?

Thanks
