$_POST data on account submit

Hello,

I have a basic hook into action ‘um_after_account_general’ which simply outputs info based from custom fields.

add_action('um_after_account_general', function() { echo "..."; }

I wish to access the $_POST data for fields on this page, when the page is submitted using the “Update Account” button.

Upon checking the $_POST value, it never sends through the data. Probably because there’s a redirect but I need to access this data before the success message.

Many thanks
