I’am trying to use woocommerce_get_order_item_totals filter hook to add some extra information into the order totals (on orders and email notifications).
JavaScript
x
add_filter( 'woocommerce_get_order_item_totals', 'display_email_topay', 10, 2 );function display_email_topay( $total_rows, $order ) { $total_rows['recurr_not'] = array( 'label' => __( '2nd Installment:', 'woocommerce' ), 'value' => 'DATA NEEDS TO GO HERE' // <=== ); return $total_rows;}I have access to $order which contains the data I want to display but I have no idea how to get it.
Below is a var_dump (formatted) of $order variable:

JavaScript

Is this possible? Any idea on how to get this specific order item meta data?

Answer
To get order item custom meta data, first you need to loop through order items, to be able to get that complex custom protected meta data using WC_Data method get_meta(). Then you will be able to get and calculate your “2nd installment cost as follows:
JavaScript
add_filter( 'woocommerce_get_order_item_totals', 'display_email_topay', 10, 2 );function display_email_topay( $total_rows, $order ) { $second_installment_cost = 0; // Initializing // Loop through order items foreach( $order->get_items() as $item ) { // Try to get "_event_ticket_info" item meta value (array) $event_ticket_data = $item->get_meta('_event_ticket_info'); // Get the data from the array if( ! empty($event_ticket_data) ) { // extract / Import variables into the current symbol table from an array extract($event_ticket_data); } // if cost and quantity variables exist and have a value more than zero if( isset($ticket_price) && $ticket_price > 0 && isset($ticket_qty) && $ticket_qty > 0 ) { // Calculating and adding 2nd Installment cost item $second_installment_cost += $ticket_price * $ticket_qty; } } if ( $second_installment_cost > 0 ) { $total_rows['recurr_not'] = array( 'label' => __( '2nd Installment', 'woocommerce' ), 'value' => wp_strip_all_tags( wc_price($second_installment_cost) ) ); } return $total_rows;}Code goes in functions.php file of your active child theme (or active theme). It should works.
