[Tiemens, Gerben]

Hi,

Your mapserver url can be extended with this paramter.. Try:
   "http://yourserv/mapserv?userid=" + customuserid + "&"

Hi,

I tried as :

var quakes = new OpenLayers.Layer.WMS( "custom", "http://gis.rtbi-iitm.in/cgi-bin/mapserv?",

{map:'/var/www/html/customisation/mapfile/tnroad.map',transparent:true},{isBaseLayer:false});
 map.addLayer(quakes);
 quakes.mergeNewParams({layers:'tnroad',userid:'2'});

But mergeNewParams is not taking any value other than defaults for map (like in this case userid ). So %userid% is not replaced  in

  DATA "the_geom from ( select * from customised_poly AS f where f.subcat_id IN (select subcat_id from subcat_info where maincat_id =0) AND user_id=%userid% )AS foo1 USING UNIQUE gid"


Thanks,
Reena.
