[mapserver-users] Itemquery problem

Thu Aug 1 06:47:06 EDT 2002

Hi all,
I'm having problems using the itemquery mode of Mapserver 3.6.1. I'm wanting
to have a text box which the user enters a postcode, which then queries a
shapefile containing postcode points. This then returns a query map of that
area. At least to start anyway.

Whatever I do and whatever is entered, itemquery returns the first record,
and itemnquery returns all the records.

What am I doing wrong? Any help would be appreciated, especially if it
includes examples of how to do it right!!
