[OpenLayers-Users] [mapserver-users] record element in query header

[Arnd Wippermann]

Hi,
 
you can try to use javascript in your template. Below an example (it's the
whole template, nothing cut out) I use to get different colors for my table
rows.
 
<script>
 
var idx = parseInt("[lrn]")%2;
var myClass = "tdBody" + idx;
 
//that should only be written for the first row
if([lrn]==1)
document.write("[provincename]<hr>");

document.write("<tr class='tblBody'>");
document.write("    <td class='" + myClass + "'>[PROJEKTNUMMER]</td>");
document.write("    <td class='" + myClass + "'>[PROJEKTBEZEICHNUNG]</td>");
document.write("    <td class='" + myClass + "'>[ART][lrn]</td>");
document.write("    <td class='" + myClass + "'>[AGNR]</td>");
document.write("    <td class='" + myClass + "'>[AG]</td>");
document.write("</tr>");
 
</script>

Betreff: Re: [mapserver-users] record element in query header



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)
