Thanks!
Here is more details on what I need to do
Suppose I have one layer which contains the province in canada and their
cities.
When the user hover or click on a province, I want this information in a
popup or a div (the client is openlayers and I use
OpenLayers.Control.WMSGetFeatureInfo)
If the user click on the province of Quebec....
There are 2000 cities in Quebec
1: city name 1
2: city name 2
...
2000: city name 2000
So In this case I think a field name should be supported in a header
template
But the problem with what you ask is that when the header is processed,
there is no active data record yet. The header is global to the layer,
not specific to any data record. If for instance, your query selected
cities from three provinces, which data field value should show up in
the header for [provincename]? Only the value corresponding to the first
record?
You'd get something like:
There are 2000 cities in Quebec
1: city name 1 (Quebec)
2: city name 2 (Ontario)
3: city name 3 (Ontario)
4: city name 4 (Ontario)
2: city name 5 (New-Brunswick)
...
2000: city name 2000
How do you ensure that your queries return results only from a single
province at a time? The answer to this question may point us to the way
to solve your problem.
