Shipping Director introduced a Sort Expression in version 1.07. The sort expression should evaluate to a string that represents an 'ordering clause'. The ordering clause is one or more (comma separated) shipping option fields: Rate, Name, Description. Each field can optionally be followed by ASC or DESC (the default is ASC = Ascending).
Examples (Don't forget, it's a string Expression, so it's typically enclosed in double quotes):
"Rate ASC"
"Name DESC"
Example using ternary if-then-else - If the cart weight <= 150, then sort by Rate, otherwise use the default sort. (The default is used when the expression results in blank string):
[$TotalWeight] <= 150 ? "Rate ASC" : ""
In this example, we'd like to sort by Rate, but we want the "Pick up ..." option at the end, so sort by Name "prefix" then Rate:
"Name.SubstringBefore("" ""), Rate"
FedEx Ground ($15.23)
FedEx Express Saver ($51.51)
FedEx Standard Overnight ($88.95)
FedEx Priority Overnight ($108.35)
Pick up at our warehouse ($0.00)
UPDATE 2020-09-17 More example sort expressions:
Explicit sort of names (using ' ? : ' if-then-else operator):
"Name = ""Ground"" ? 1 : Name = ""Priority"" ? 2 : Name = ""Special"" ? 3 : 4"
