add_action( 'wpcf7_mail_sent', function ( $contact_form ) use ( $wpide_cf7_slack_fields ) {

        $value = $submission->get_posted_data( $name );
        if ( null !== $value && '' !== $value ) {
            $value   = is_array( $value ) ? implode( ', ', $value ) : (string) $value;
            $lines[] = sprintf( '*%s:* %s', $name, wp_html_excerpt( str_replace( array( '<', '>', '&' ), array( '&lt;', '&gt;', '&amp;' ), $value ), 500, '…' ) );
        }
