CGI Query Mode Variables

[ANDY CANFIELD]

You need to make a template for each layer. When you query the it will use
the template you specify for that layer.

Say you do a query like:
mode=QUERY&layer=AnyGivenLayer

Mapserver is going to look at the map file definition of "AnyGivenLayer" and
use the template specified in the layer definition for the display of the
returned query information.

You can use the same template for multiple layers if they have similar
attributes. For instance I have about twent eqpuitment layers in one of my
maps but all of them have the same five attribute fields so in the map file
I specify the same template for each of those layers.

When I use Mapserver in CGI mode I generally have about 75% of the amount of
templates as I do layers so for a map of 100 layers I have 75 specific
templates.

Does this help?
