Duplicate RSVP’s

Hey there @mattmccomas!

Thanks for reaching out.

Give this snippet a shot in your child theme’s functions.php file:

/**
 * Disable just the Submit button of the Event Tickets form after initial click to protect against sending data multiple times
 * From https://gist.github.com/cliffordp/8bceb54b440fbe9de1d42df6f231cc7a
 * By Matt B.
 * Updated 2017-01-13 for latest versions of ET/ET+
