This shortcode will return the content of a custom field from the current contact’s record in your ActiveCampaign application.
[mbr_db_email] [mbr_db_id] [mbr_db_first_name] [mbr_db_last_name] [mbr_db_my_custom_field] [mbr_db_some_other_field]
For security reasons [mbr_db_password] will not return any value.
To use this shortcode in your own PHP code, please use as follows:
$my_custom_field = mbr_get_contact_field('my_custom_field');
