[Qgis-developer] Update Fields Selected Features.

[Luís Miguel Royo Pérez]

Hello everyone,

I'm trying to modify the values of some selected features. I have 
written this small script, but nothing happens when I run it. Is there 
something that I've missed? Here is my code.

/lyr = qgis.utils.iface.activeLayer()//
//features = lyr.selectedFeatures()//
//
//lyr.startEditing()//
//lyr.updateFields()//
//for f in features://
//    fid= f.id()//
//    lyr.changeAttributeValue(fid,12,"0")//
//    lyr.updateFeature(f)//
//    print "elemento alterado"//
//
//lyr.commitChanges()/

Thanks per advance!!
