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 OK, I got to find another solution
The client I use is openlayers I configured this control OpenLayers.Control.WMSGetFeatureInfo So when I click on a province, this query is launched /cgi-bin/mapserv.exe?map=PORTAL&&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&LAYERS=RSSavertissements&QUERY_LAYERS=RSSavertissements&STYLES=&BBOX=-8882077.807097%2C5589075.535908%2C-6925289.883347%2C7545863.459658&FEATURE_COUNT=10&HEIGHT=400&WIDTH=400&FORMAT=image%2Fgif&INFO_FORMAT=text%2Fhtml&SRS=EPSG%3A900913&X=333&Y=277 The text returned is defined by the template that is why I though the solution would be on mapServer side. thanks steve Daniel Morissette <[email protected]>@lists.osgeo.org Envoyé par : [email protected] 07/04/2010 03:46 PM A [email protected] cc Objet Re: [mapserver-users] record element in query header [email protected] wrote: > > 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.
