Script tool multiple input fields parameter...HELP!

MatthewRusso

I have a script tool where it takes an input table and "MULTIPLE INPUT FIELDS"

It then runs a cursor and all i want to do is print out each row with the 3 field values.  If i do 3 parameters for the fields, it works.  If i do the mutliple it wont.  I tried printing out the value and it looked like this:  fields = "ID;Lat:Long"

I guess it needs to be in list format to run through the cursor as a row?

Here is my code

inFeat = arcpy.GetParameterAsText(0)
fields = arcpy.GetParameterAsText(1)

with arcpy.da.SearchCursor(inFeat, [fields]) as cursor:
     for row in cursor:
     arcpy.AddMessage(row[0], row[1], row[2])

The list of fields depends on the way you read your parameter.

If you use "arcpy.GetParameterAsTekst()", then the list will be a single string where the different items are separated by semicolons. To avoid this you could use "arcpy.GetParameter()", this will yield a list of field objects. Neither one of them is directly useful for specifying the fields in a cursor.

# use:
fldstekst = arcpy.GetParameterAsText(1)
flds = fldstekst.split(';')
# or:
lst_flds = arcpy.GetParameter(2)
flds = [fld.name for fld in lst_flds]

# then use:
with arcpy.da.SearchCursor(inFeat, flds) as cursor:
    for row in cursor:
        arcpy.AddMessage(row[0], row[1], row[2])

Be aware that if less than 3 fields have been selected that this will yield an error (index out of range).
