Problem:
When I submit my cred form with id#23 I want data picked from my data custom field "wpcf-end-data-time-tour" to be also submitted to another field "_expiration-date" (in format Unix timestamp)

Solution:
Please replace line #6 with this line of code:

update_post_meta($post_id, '_expiration-date', $end_tour_data);

Please double check custom field slug is correct, if it's types field then wpcf- needs to be added.
