I suggest that you do it manually and follows the way the widget works.  
First the features are downloaded in GML format and then they are 
converted in shape file format using the php_ogr library.

You can get the URL request by printing szURL in getGML in the 
chameleon/htdocs/widgets/LayerAttributes.php file.  You can check if 
there are any features and save them in a file.   Then you can call the 
ogr2ogr function  through a PHP script on you GML file (e.g.:  
ogr2ogr(myGMLfile, output.shp, "ESRI Shapefile").  The ogr2ogr.php 
script can be found in chameleon/htdocs/common/ogr.

This is just an idea on how it could be tested.
