[Chameleon] Custom Query Results

Hi Tracy,
I have enabled this functionality for MapServer WMS Sources. If this is
your primary datasource then the following lines of code shold suffice:
LINE 958 QueryResults.phtml
if( stristr( $szValue, 'http://' ) )
$szResult .= "<td><p
class=\"CWCQueryResultsValue\"><a href='".$szValue."'
target='_blank'>Click here for more information</a></p></td>\n";
else
$szResult .= "<td><p
class=\"CWCQueryResultsValue\">".$szValue."</p></td>\n";
If you are using local datasources (eg, shp, OGR-based, etc.) then some
additional coding will be required. Essentially you must mimick the WMS
version of the code. QueryResults.phtml handles three different
datasources - local, MapServer WMS, and CubeServ WMS. Find the
appropriate loop for printing out Attribute values and replacestrings as
necessary. I hope to have this functionality integrated within the
Query widget for various protocols in the near future.
Hope this helps,
Jason
