Thanks for the idea.
I am currently using something like this:
vectors.onFeatureInsert=
function(feature) {
var wktwriter=new OpenLayers.Format.WKT();
var wkt=wktwriter.write(feature);
}
vectors being the vector layer obviously.
Not sure if the above is correct but at least the output is something I can
use to store and retrieve from the DB.
I am probably going to save the output temporarily in the variable and save
it in the DB when the user is done editing the map.
Now on to deleting/removing a feature...
Thanks again.
