[mapserver-users] record element in query header

[Steve.Toutant at inspq.qc.ca]

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

Perhaps I misunderstood what should be managed by the client or the 
server??

thanks again
Steve

I'm not exactly sure if a field name should be supported in the header 
template, but based on a quick browse of the code there are two other 
ways you could possibly pass the information (depending on what you have 
on the client side):

1- You can use parameters from the URL in a template tag. e.g. if you 
pass myprov=Quebec in the URL then you should be able to use [myprov] in 
your template.

2- You can reference layer-level metadata in query templates using 
[metadata_...]

(Those are untested hints based on a quick browse of the source)
