[Qgis-developer] Getting and setting attribute field names and values for vector layers

[Giuseppe Sucameli]

Hi Ole,
to get the field names you have to use the vector data provider.

If vl contains the vector layer than:


provider = vl.dataProvider()  # QgsVectorDataProvider
fields = provider.fields()  # QMap<int, QgsField>

... # vl.select(), feat = QgsFeature(), while vl.nextFeature(feat):

    attrs = feat.attributeMap()
    for (k,attr) in attrs.iteritems():
        name = fields[ k ].name()
        print "%s: %s" % (name, attr.toString())


Regards.
