I am using AMPscript in Salesforce Marketing Cloud to parse serialized JSON data for hotel reservations. Each entry contains start and end dates along with a daily rate. I need to calculate and display rates for each day of the stay, excluding the rate for the checkout day.
Data example:
[{"start":"2024-08-22","end":"2024-08-24","amount":546.4}, {"start":"2024-08-24","end":"2024-08-25","amount":581.68}]Desired Output:
• August 22, 2024: $546.40• August 23, 2024: $546.40• August 24, 2024: $581.68However, my current implementation incorrectly includes an entry for the checkout day and duplicates the rate for the transition day:
AMPscript Snippet:
%%[Set @json = AttributeValue("serializedresdata")Set @rows = BuildRowsetFromJSON(@json, "$[*]", true)For @row = 1 TO RowCount(@rows) do Set @rowData = Row(@rows, @row) Set @start = Field(@rowData, "start") Set @end = Field(@rowData, "end") Set @amount = Field(@rowData, "amount") Set @startDate = DateParse(@start) Set @endDate = DateParse(@end) Set @dateDiff = DateDiff(@startDate, @endDate, "D") For @i = 0 TO @dateDiff - 1 do Set @currentDate = DateAdd(@startDate, @i, "D") Set @formattedDate = FormatDate(@currentDate, "MMMM dd, yyyy") Output(Concat("<p>", @formattedDate, ": $", FormatCurrency(@amount, "en-US"), "</p>")) next @inext @row]%%Issue:The output incorrectly displays:
• August 22, 2024: $546.40• August 23, 2024: $546.40• August 24, 2024: $546.40 (should not include as start of new reservation)• August 24, 2024: $581.68• August 25, 2024: $581.68 (checkout day, should not display)How can I adjust the AMPscript to avoid duplicating the daily rate for the transition day and exclude the checkout day’s rate?
Any assistance would be greatly appreciated!
