Question relating to queries

You can do it a couple of ways. One is to use frames. The other is to
embed a normal mapserver form in a query template. The image in that
form has to be created with another call to the mapserver (i.e. <img src="/cgi-bin"...>
or <input type="image" src="/cgi-bin"...>. With 3.2 there is no way to isolate
the returned shapes (eg. hilite) but you can create a map of the queried area.
You could even save a reference to the last image using hidden variables
and passing the image url through to the query page. I have several apps
that embed maps on the query results. Here's an example:

The Recreation Compass at the DNR, zoom into the SE portion of the
state and click on any of the yellow-orange polygons. I use the extent of
the shape to build a map with different data than is on the compass. I even
go so far as to compute scales for the map to be created and if the area
is too small I recompute with some minimum scale an recompute. Use MSIE
to actually view the code. http://www.dnr.state.mn.us/compass 

Here's an example with frames: http://www.dnr.state.mn.us/minerals/testing/

Map activies happen in one frame, mapserver query results are in another and
hits on msql in yet another. Works pretty nice.

Hope this helps.

Paul,

   I've been thinking of doing this too.    I'm going to try frames
instead of a table to create several "panes" on the web page,
one of which will be for query results.
