[Hans Palmborg]

Hello!

How to zoom in and color the match/matches of the question with
queryByAttributes?

//CODE IN PHP
if ( $http_form_vars["Querystring"] )
 {
 $szQuerystring = $http_form_vars["Querystring"];
 $oParcelLayer = $oMapSession->oMap->getLayerByName("Layername");
 $oParcelLayer->queryByAttributes("Columnname", "$szQuerystring",
        MS_MULTIPLE );
 }

Please help!!
