This looks ok to me. I aim to let the user select a feature from first layer in only dataframe. Then click the button on the addin tool bar. Using the selection and the MAP_NUMBER field concatenate a path and add the appropriate feature class. Can anyone tell me why the layers are not being added.
import arcpy
import pythonaddins
class ButtonClass1(object):
"""Implementation for add_Layers_addin.button (Button)"""
def __init__(self):
self.enabled = True
self.checked = False
def onClick(self):
#set the map document reference
mxd = arcpy.mapping.MapDocument("CURRENT")
#set the dataframe reference using the map document and the first data frame in the list
df = arcpy.mapping.ListDataFrames(mxd)[0]
#set the layer reference using the map document reference and the second layer in the list of layers
layer1 = arcpy.mapping.ListLayers(mxd)[0]
#create a search cursor to get relevant information about a parcel
sc = arcpy.SearchCursor(layer1)
#for loop to get the selected data
for row in sc:
#select the relevant fields to be put on the map
ap = row.getValue("MAP_NUMBER")
addLayer = r'G:\Texas\Potter-Randall\Database' + '\\' + str(ap) + '\\' + str(ap) + ".gdb" + '\\' + str(ap)
arcpy.mapping.AddLayer(df, addLayer, "BOTTOM")
#refresht the active view
arcpy.RefreshActiveView()
#delete search cursor and row variables
del sc
del row
