hook to display value in donation meta

You should be able to add additional personal information into that metabox with this action: give_payment_personal_details_list

Thanks!

A really useful tool for finding things like that is our own version of “Show Only Hooks” which we call “Give Hook Helper”. You can install it from here:

Thanks. Could you give an example snippet of how this hook can be used to display a payment meta field?

This is what I added in my functions.php, it did not work.

/**
 * Show Phone No. in Payment Details
 *
 * @param $payment_meta
 * @param $user_info
 */
function give_show_phone_no( $payment_meta, $user_info ) {
    $give_phone = give_get_meta( $payment_id, '_give_phone', true );
        if ( $give_phone ) : ?>
        <b><?php _e( 'Phone No:', 'give' ); ?></b>
        <?php echo $give_phone; ?>
    </div>
        <?php endif;
 }

add_action( 'give_payment_personal_details_list', 'give_show_phone_no', 10, 2 );

^ That worked. Thanks!
