[OpenLayers-Users] CQL queries with WFS

[Brenningmeyer, Todd]

Bart,
I tried escaping the quotes around the value of the nomos but unfortunately it didn't change the returned results.  I used backslashes in front of the single quotes around Eleia.  Is this what you had in mind?  It may be that I'm not escaping the right part of the filter.
Thanks,
Todd
           wfsLayer = new OpenLayers.Layer.WFS( "villages",
                http://localhost/cgi-bin/mapserv.exe?map=../htdocs/amap/sites_wfs.map&CQL_FILTER=nomos=\'Eleia\'&typename=villages&request=getfeature&version=1.0.0&service=wfs,{
               { 
                styleMap: oStyleMap
                }
            );

Have you tried escaping the value of your parameter CQL_FILTER?

Best regards,
Bart
