Hi,
your request looking fine in the OpenLayers code.
When you looking for the link in your first mail you have the style
example for heatmap.
You have to replace in line 21 <ogc:Literal>pop2000</ogc:Literal> with
<ogc:Function name="env">
<ogc:Literal>weightAttr</ogc:Literal>
<ogc:Literal>population</ogc:Literal> --> this is an optional
default value
</ogc:Function>
The same you have to use for pixelsPerCell in line 32
<ogc:Function name="env">
<ogc:Literal>pixelsPerCell</ogc:Literal>
<ogc:Literal>10</ogc:Literal> --> this is an optional default value
</ogc:Function>
In radiusPixels the funcionality is already implemented in the example.
outputBBox and outputWidth already uses the predefinend values, you not have to
integrate in the env parameter on request.
Hope that helps.
Regards
Nikolai
