[OpenLayers-Dev] Add Vector attributes

[geojoe]

What I really need to know is how to is (1, 2, and 4):
    1. Select features from a (PostgreSQL) layer where ownerID = myID
    2. Draw the result set as a vector layer with a siteID attribute.
    3. Add and enable a drag drop control.
    4. After a feature is moved 'onComplete', update the feature geom in the
(PostgreSQL) layer
    5. Refresh the layer 'layer.redraw(true)'.


function init() {
...
	if( myID>0 ) {
		mySiteVectors = new OpenLayers.Layer.Vector("My Sites", 
				{style: result_style, 'displayInLayerSwitcher': true});
		map.addLayer(mySiteVectors); 

                map_controls = {
	              drag: new OpenLayers.Control.DragFeature( mySiteVectors,	
			{	'onComplete': updateGeom	})
                };

                for(var key in map_controls) {
                    map.addControl(map_controls[key]);
                }

		createSiteFeatures(myID);
	}
...
}

/* Should be getting info from "all_sites" (PostGres) layer where ownerID =
myID. */
function createSiteFeatures(myId) {
    var colors = ["red", "orange", "yellow", "green", "blue", "purple",
"black", "black"];
    var features = new Array(20); 
    var x,y, fill;
    var cnt, layers, layer,siteID;
    var cosLat = Math.cos(44*Math.PI/180);
    var cX = mapExtent[0];  //lower left X  google 900913
    var cY = mapExtent[1];  //lower left Y
    var dY = Math.abs( (mapExtent[3] - mapExtent[1])/2 );
    var dX = Math.abs( (mapExtent[2] - mapExtent[0]) ) / cosLat;

    layers = map.getLayersByName("My Sites");
    if( layers ) {
        layer = layers[0];
    } else {return false;};

    for(var i=0; i<features.length; i++) { 
	x = cX + (Math.random()*dX);
	y = cY + (Math.random()*dY);
        siteID = '"'+i+'"';
        fill = colors[5];//colors[Math.round((colors.length - 1) *
Math.random())]; 
	features[i] = new OpenLayers.Feature.Vector(
             new OpenLayers.Geometry.Point(x, y),null, {fillColor: fill,
pointRadius: 8, "siteId":siteID}
        );
    }

    layer.addFeatures(features); 
    layer.setOpacity(0.5);
    toggleControl("drag");

    return 1;
}
