Vendor Email Notification

Yeah possible, where you want to show this? At top or bottom?

Please add this code snippet to your site and take a look –

add_action ( 'wcfm_order_totals_after_total', function( $order_id ) {
	$order = wc_get_order( $order_id );
	if ( WC()->payment_gateways() ) {
		$payment_gateways = WC()->payment_gateways->payment_gateways();
	} else {
		$payment_gateways = array();
	}
	$payment_method = ! empty( $order->get_payment_method() ) ? $order->get_payment_method() : '';
	
	$td_style = '';
	if( $payment_method ) {
		?>
		<tr>
			<th class="label" colspan="2" style="text-align:right; <?php echo $td_style; ?>"><?php _e( 'Payment Method', 'wc-frontend-manager' ); ?>:</th>
			<td class="total" style="text-align:center; <?php echo $td_style; ?>">
				<div class="view">
					<?php 
					echo isset( $payment_gateways[ $payment_method ] ) ? esc_html( $payment_gateways[ $payment_method ]->get_title() ) : esc_html( $payment_method );
					?>
				</div>
			</td>
		</tr>
		<?php
	}
}, 50 );
