First you should use woocommerce_add_cart_item_data
action hook, to store your Custom Post Type (CTP) Id on add to cart… But for that you will need to display, on your CTP pages, inside the add to cart form, a hidden field with the CTP Id like:
<input type="hidden" name="ctpost_id" value="<?php echo get_the_id(); ?>">
Now you can add this hooked function, that will add as custom cart item data your CTP Id:
add_filter( 'woocommerce_add_cart_item_data', 'add_custom_cart_item_data', 10, 3 );
function add_custom_cart_item_data( $cart_item_data, $product_id, $variation_id ){
if( isset( $_POST['ctpost_id'] ) ) {
$cart_item_data['ctpost_id'] = wc_clean( $_POST['ctpost_id'] );
}
return $cart_item_data;
}
The Second hook to be used is woocommerce_checkout_create_order_line_item
action hook, to add custom order item meta data (or to make changes to order item data). This hook is triggered before payment gateways process during order creation.
You can use WC_data
add_meta_data()
method to save your CTP Id as a custom CTP ID like:
add_action( 'woocommerce_checkout_create_order_line_item', 'save_cpt_id_to_order_item_data', 10, 4 );
function save_cpt_id_to_order_item_data( $item, $cart_item_key, $cart_item, $order ){
if( isset($cart_item['ctpost_id']) && $cart_item['ctpost_id'] > 0 ) {
// Add the custom CTP post ID
$item->add_meta_data('_ctpost_id', $cart_item['ctpost_id'] );
}
// And here for example you add seats as custom cart item data
if( isset($cart_item['quantity']) ) {
$item->add_meta_data( 'Seats', $cart_item['quantity'], true );
}
}
When the order will get paid, you will be able to update everything required, as you will have your CTP post ID as custom order item data.
Then finally, you can use woocommerce_payment_complete
as follow:
add_action( 'woocommerce_payment_complete', 'action_payment_complete_callback', 10, 1 );
function action_payment_complete_callback( $order_id ){
$order = wc_get_order();
// Loop through order items
foreach ( $order->get_items() as $item_id => $item ) {
$ctp_id = $item->get_meta('_ctpost_id'); // Get the CTP post ID
// Your code goes here
}
}
Or woocommerce_order_status_changed
hooks like:
add_action( 'woocommerce_order_status_changed', 'action_order_status_changed_callback', 10, 4 );
function action_order_status_changed_callback( $order_id, $status_from, $status_to, $order ){
if( in_array( $status_to, ['processing','completed'] ) ) {
// Loop through order items
foreach ( $order->get_items() as $item_id => $item ) {
$ctp_id = $item->get_meta('_ctpost_id'); // Get the CTP post ID
// Your code goes here
}
}
}
