CGI Qlayer,Qstring variables usage

[Daniel Goetz]

Hi,
I have two suggestions (but I am not quiet sure whether this is right):

first I think you should put the value for "mode" from "map" to "query" or "itemquery" or itemnquery" or something like that.

Second: I could not understand your qstring expression. In my little mapserver project I have the possibility to search for features that have the same values in a special database column. For example: When I want to search for all objects that have the value "13" in the database-column "TM_NR" then my qstring looks like this: "qstring=TM_NR=13". Very simple, but it works.

Perhaps you could try this. But as I mentioned I don't really know whether it works or not.


Good luck and bst regards

Daniel
