[Qgis-user] Get layer-id by layer (not by acive layer)

[Nathan Woodrow]

layer.id() returns the id

http://qgis.org/api/classQgsMapLayer.html#a710f27dec806d3bcd5ae14701c2e6fd7

layer.name() returns the name

http://qgis.org/api/classQgsMapLayer.html#aff7fb3990b6c736fbe41643666b027e5

If you have a layerid and you want to look up the layer object for it you
can use:

QgsMapLayerRegistry.instance().mapLayers[layerid]

if you have a name and would like the layers objects:

maplayers = QgsMapLayersRegistry.instance().mapLayersByName(name)
