I've tried a lot of times to use the OpenLayers CQL example but nothing changes. Is there any way to use CQL or filter.

which example are you trying to use? what goes wrong? – iant Jan 8 '13 at 10:06
Are you using Geoserver? CQL filters don't work with any other WMS service. – user1702401 Jan 8 '13 at 10:07

You have CQL in example:


Try to change B to A and you will see change


BTW OpenLayers supports less function then GeoServer but you can read

try to use this code:

lyr = new OpenLayers.Layer.WMS(yourLayerName, yourLayerService,{
      'VERSION' : '1.1.0',
      'layers' : yourLayerNum,
      format: 'image/png',
      transparent: true,

      isBaseLayer: false


dont forget VERSION is important for getting true result.

i hope it helps you...
