[OpenLayers-Users] Style WFS layer by attributes

[Jerome Freyre]

Try to apply a stylemap to your vector layer.

// Creation of a stylemap
myStyles = new OpenLayers.StyleMap({
        "default": new OpenLayers.Style({
            strokeColor: "${getFillColor}",
            fillColor: "${getFillColor}",
            strokeWidth: 2,
            strokeOpacity: 1,
            fillOpacity: 0.7,
            pointRadius: 5
        },{
            context: {
                getFillColor:function(feature) {
                    if (feature.attributes.state == true)
                        return '#00FF00';
                    else if (feature.attributes.state == false)
                        return '#FF0000';
                }
            }
        })
        ,"select": new OpenLayers.Style({
            fillColor: "#00000FF",
            strokeColor: "#0000FF",
            pointRadius: 6
        }),
        "hover": new OpenLayers.Style({
            fillColor: "#CCCCCC",
            strokeColor: "#999999",
            pointRadius: 6
        })
    });

// Create a vector layer and give it your style map.
var points = new OpenLayers.Layer.Vector(
                 'Points', {styleMap: myStyles}
             );

if you still have problems, please send you script, i'll try to debug
