Hello John.

Thank you for reaching out to us.

For sending emails, you can use this:

https://www.a2hosting.com/kb/installable-applications/optimization-and-configuration/wordpress2/sending-e-mail-in-wordpress#:~:text=To%20send%20an%20e%2Dmail,authentication%20settings%20you%20defined%20above

And to take values after Apply is hit, there's this hook:

wpdatatables_after_frontent_edit_row( $formdata, $rowId, $tableId ) This action is executed after editing action is applied.

$formdata is the array of keys and values for editing.

$rowId is the ID field of the row in MySQL table that was edited.

$tableId is the table identifier from the MySQL plugin table (wp_wpdatatables).

For example:

function sendEmailAfterEdit( $formdata, $rowId, $tableId ){ // create logic for sending emails } add_action('wpdatatables_after_frontent_edit_row', 'sendEmailAfterEdit',10,3);

will be triggered in both cases when you edit or adding a new row in the table from front-end. Please note that data is already saved in database.
