Unless you have some crazy old version of Geoserver, you do NOT need to create
a template on the server side. Just make the infoformat parameter “JSON” to get
back GeoJSON rather than text/html.
I’ve accomplished what you are trying to do on several projects. Keep in mind
that the GeoExt popup inherits from Ext.Window so you should configure the
contents just as you would for that.
What I do is:
1. create XTemplates, either in hidden markup or in a separate js file
2. key the templates by the featureType (either as the div id or as a
javascript object key)
3. apply the appropriate template for each feature returned
4. create a GeoExt popup with the HTML created in step 3 inserted in the
correct place
So your GFI handler would be something like this:
> getfeatureinfo: function(e) {
if(e.features && e.features.length){
var results = {};
//Loop through the different features, apply templates, and store results in a
featureType keyed object
Ext.each(e.features,function(feat){
var type = feat.fid.split(‘.’)[0];
if(!results[type]){results[type]=[]}
results[type].push(MyTemplates[type].apply(feat.attributes));
});
var popItems = [];
//Loop through returned featureTypes and create a panel for each one to put
into the
//popup’s accordion layout
Ext.iterate(results,function(ftype,vals){
var panel = {
title:ftype,
html:’<div>’+vals.join(‘</div><div>’)+’</div>’,
width:400}
popItems.push(panel)
});

I wrote this on the fly, so beware of typos and not quite complete logic, but
that should at least get you started on the right path

Hi Robert,
What you can do in fact is:
- Make a geoserver template that will return your data in JSON format
- Then, process the data as you wish on the client side (this is, using GeoExt)
Below you can find an example of content.ftl that is returning the data in JSON
format.
[{
<#assign i = 0 />
<#list type.attributes as attribute>
<#if (i >= 0) && (!attribute.isGeometry)>
"${attribute.name}":
<#list features as feature>
<#assign k = 0 />
<#list feature.attributes as attribute>
<#if (k = i) && (!attribute.isGeometry)>
"${attribute.value}"
</#if>
<#assign k = k+1 />
</#list>
<#if attribute_has_next>
,
</#if>
</#list>
</#if>
<#assign i = i+1 />
</#list>
}]
hope this helps.
Cheers,
Hugo

Hi,
Standard format... text/html as defined in the Parameter tab in Firebug.
I have read that if the format is changed, then the attributes can be
manipulated ie fields can be left out. I haven´t seen any code fór it though.
I have tried with the content.ftl file in the geoserver workspaces, but the
results are pretty grim! I would rather do it in javascript so that everything
is kept in my app and not spread around different applications.
yours,
Rob
