Multiple single inserts

I have a booking form that inserts a booking into the database using a single insert. On the same page I also want to optionally add 6 other booking options. Each option is stored in a seperate table with a foreign key to the main booking table.
2 questions

1 - do I need to set up a relational table for each of these or can I simply add the stored session id of the main insert in the foreign key field?
2- Only the main booking table is guaranteed a value. The others are optional. If I create single inserts for all the other optional bookings using the insert button on the main booking form blank values will be added to all the tables.
I can see a way around this by creating repeat regions for all of the optional bookings and setting the repeat to 1. Then I can specify if a field is blank don't insert the record. Is this the only work around or is there an easier way. Also can you name the repeats as I have 6 repeats all named Repeat selection (1) and it is a little confusing when trying to create the insert records.

No, you do not need to set up a relational table for each option. the first insert record behavior will create a session variable that contains the ID number of the last inserted record, use this session in each of the insert record behavior.


each additional option form element should have a unique name, in the insert record behavior, you can click the lightning bolt next to the trigger and select the appropriate form element so the insert will only take place if that element has a value.

I have multiple single inserts on a page. I have the main insert that creates a SESSION value and then the other inserts use that as a foreign key. The problem is all the other tables have an auto increment primary key and when click the insert button it inserts a record for each table even if they are blank. How do I stop this as I am getting a huge amount of blank records.

set the triggers for the other inserts to use the form elements their data is coming from.

Click the lightning bolt next to trigger and select the appropriate form element.
