Hello,
You can define your own onComplete method for your drag control. It
will be call everytime a feature is done dragging :
http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Control/DragFeature-js.html#OpenLayers.Control.DragFeature.onComplete
In it, you can save your features to your DB. If you look at the
HTTP protocol, you'll see a commit method you can use for this purpose.
You can start there :
http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Protocol/HTTP-js.html#OpenLayers.Protocol.HTTP.commit
HTH,
Alexandre

Hello! How to keep new coordinates in db when the user moved a point?
So I create points:
/ var layerNodes = new OpenLayers.Layer.Vector("Nodes", {//
// strategies : [new
OpenLayers.Strategy.BBOX({resFactor: 1.1})],//
// protocol : new OpenLayers.Protocol.HTTP({//
// url : "get_layers.php?mode=GetNodesMarkers",//
// format : new OpenLayers.Format.Text()//
// })//
// });//
// map.addLayer(layerNodes);/
And how to make line change (it is necessary, that the user could
extend line) and to keep new coordinates in a DB?
So i create the line:
/lineLayer = new OpenLayers.Layer.Vector("Lines");//
// map.addLayer(lineLayer);//
// var line = new OpenLayers.Geometry.LineString(points);//
// line.transform(new OpenLayers.Projection("EPSG:4326"), new
OpenLayers.Projection("EPSG:900913"));//
// var lineFeature = new OpenLayers.Feature.Vector(line, null,
style_arr[CableLine_arr[k]['style']]);//
// lineLayer.addFeatures([lineFeature]);/
Movement of lines and points I plan to do, as here:

Thanks for answers!
