[OpenLayers-Users] Correct format for cql_filter in WMSgetFeatiureInfo

[Asle Benoni]

Thanks! Clear enough but not for a newbie like me :-) Could you supply a
sample code for this? I have all the layers in an array layers[n]. How
would I write the code? I have a cql_filter that I apply a search filter
and I use a function like this:

var mLayers = map.layers;
for(var a = 4; a < (mLayers.length); a++ ){
    mLayers[a].mergeNewParams({'CQL_FILTER': param});
    mLayers[a].setVisibility(true);
}}
