[Mapserver-users] qstring - multiple values

[Fawcett, David]

I figured out the syntax for the expression.  Here is an example that works for me:

The relevant parts of the URL are ...mode=itemnquery&qlayer=basemap&qstring=('[FIPS]'+IN+'27001,27003,27005')


This is an example where I wanted to select records with a value of 27001, 27003, or 27005 in the FIPS field.  (string type field)

You can see that I also was able to omit qitem=FIPS from the URL because it is contained in the expression in the qstring.  (It works with it there too, but I assume that it is ignored)

Thanks for the help Steve!
