Salesforce Asked on January 4, 2022
Thanks for taking your time to review my question. We have a complex situation that we need to use ampscript to display different content based on the webinar attendance. The data is stored in Three data extensions named "audience"(send data),"event(event_ID and Email)","Webinar names(Event_ID,EVent_name)". We have our var set and used "IF" statement for different content display.
The issue is when certain audience who has multiple IDs(watched multiple webinar), we are not able to us "IF"statement to display multiple content. I am just wondering if we can achieve this with LOOP function ?
Our desired email would be:
Hello %%=v(@firstname)%%
Thanks for watching %%=v(@event_name)%%
(multiple)
Here is more content you might like (Multiple based on the event.
Here’s the code we have so far `
%%[ var @subkey, @Fname, @email, @event_id, @rows, @row, @rowCount, @subKey, @counter, @Event_name
set @subKey = subscriberkey
set @Fname = FirstName
set @email = EmailAddress
set @event_id = lookup("event","Event_ID","Email_address", @email)
set @Event_name = Lookup("Webinar names", "Event_Name", "Event_ID", @event_id)
]%%`
%%[IF @event_id != "54321" and @event_id != '135135' THEN]%%
CONTENT FOR A
%%[ENDIF]%%
<br>
%%[IF @event_id != "12345" and @event_id != '135135' THEN]%%
CONTENT FOR B
%%[ENDIF]%%
<br>
%%[IF @event_id != "12345" and @event_id != '54321' THEN]%%
CONTENT FOR C
%%[ENDIF]%%
Here's how I'd approach this -- loop twice through the subscriber's events with the first loop qualifying the events with a matching event_name
and looping again to build the output string.
In the recommendation section, you can use the indexOf() function to determine if a person has attended a particular series of events or not and then output the content that's in line with your requirements.
%%[
set @debug = 1
/* pull email address from system string */
set @EmailAddress = AttributeValue("emailaddr")
set @firstName = AttributeValue("FirstName")
set @attendedEvents = LookupRows('event','Email_address', @EmailAddress)
set @rowCount = rowcount(@attendedEvents)
if @debug == 1 then
output(concat("<br>rowCount: ", @rowCount))
endif
set @attendedEventNames = ""
set @attendedEventIds = ""
set @qualifiedEventCount = 0
/* qualified event loop -- events with a webinar names match */
for @i = 1 TO @rowCount do
set @row = row(@attendedEvents,@i)
set @eventID = field(@row,'Event_ID')
set @event_name = Lookup("Webinar names", "event_name", "Event_ID", @eventID)
if @debug == 1 then
output(concat("<br>eventID: ", @eventID))
output(concat("<br>event_name: ", @rowCount))
endif
if not empty(@event_name) then
set @qualifiedEventCount = add(@qualifiedEventCount,1)
set @attendedEventNames = concat(@attendedEventNames, "|", @event_name)
set @attendedEventIds = concat(@attendedEventIds, "|", @eventId)
/* strip leading delimiter from first element */
if @qualifiedEventCount == 1 then
set @attendedEventNames = replace(@attendedEventNames,"|","")
set @attendedEventIds = replace(@attendedEventIds,"|","")
endif
endif
next @i
if @debug == 1 then
output(concat("<br>qualifiedEventCount: ", @qualifiedEventCount))
output(concat("<br>attendedEventNames: ", @attendedEventNames))
output(concat("<br>attendedEventIds: ", @attendedEventIds))
endif
if @qualifiedEventCount == 0 then
raiseError("No qualifed events for subscriber", 1) /* skip the send to this subscriber */
endif
set @attendedEventNamesOutput = ""
set @qualifiedEventNamesRowset = buildrowsetfromstring(@qualifiedEventNamesRowset,"|")
set @rowcount = rowCount(@qualifiedEventNamesRowset)
if @debug == 1 then
output(concat("<br>rowCount (2): ", @rowCount))
endif
/* qualified event output loop -- build a punctuated output string */
for @i = 1 to @rowcount do
set @row = row(@qualifiedEventNamesRowset, @i)
set @eventName = field(@row,1)
if @i == 1 then
set @attendedEventNamesOutput = @eventName
elseif @i == @qualifiedEventCount then
set @attendedEventNamesOutput = concat(@attendedEventNamesOutput, " and ", @eventName)
else
set @attendedEventNamesOutput = concat(@attendedEventNamesOutput, ", ", @eventName)
endif
next @i

Hello, %%=properCase(@firstName)=%%. Thanks for watching %%=v(@attendedEventNamesOutput)=%%.
<br><br>Here is more content you might like:
%%[ /* output content based on events attended */ ]%%
%%[ if indexOf(@attendedEventIds, "12345") > 0 and indexOf(@attendedEventIds, "23456") == 0 and indexOf(@attendedEventIds, "9876") == 0 then ]%%
%%[ /* attended 12345, but not 23456 and 9876 */ ]%%
<p>CONTENT HERE</p>
%%[ elseif indexOf(@attendedEventIds, "2345") == 0 and indexOf(@attendedEventIds, "789") == 0 then ]%%
%%[ /* attended 2345, but not 789 */ ]%%
<p>CONTENT HERE</p>
%%[ endif ]%%
