在Woocommerce中访问和显示订单商品元数据

Question

In Woocommerce I am trying to display the results of order item object and to access it:

$product_meta = $item->get_meta_data();
print_r ($product_meta);

This is what I am trying to pull:

EDIT: This is the output that I get using $item->get_formatted_meta_data( '', true ):

To get all order item meta data, you will use WC_Order_Item get_formatted_meta_data() method with specific arguments, this way:

// Accessible non protected Order item meta data
$item_meta_data = $item->get_formatted_meta_data( '', true );

// Formatted raw Output
echo '<pre>'; print_r($item_meta_data); echo '</pre>';

To access some order item properties, you can use any WC_Order_Item_Product method like:

$item->get_product(); // Get the WC_Product object

$item->get_product_id(); // Get the Product ID

$item->get_variation_id(); // Get the Variation ID

$item->get_name(); // Get the Product name

$item->get_quantity(); // Get the item quantity 

// and so on …

Then if you need to access a specific "custom" order item data value, you will use WC_Data get_meta() method:

$custom_value = $item->get_meta("_custom_key");

See: Get Order items and WC_Order_Item_Product in Woocommerce 3

Update (displaying your required custom order item meta data)

The data you need can be accessed and displayed this way:

if( $lessons = $item->get_meta('lessons') ) {
    echo '<p>Lessons: '.$lessons.'</p>';
}

if( $tour_guide = $item->get_meta('tour guide') ) {
    echo '<p>Tour Guide: '.$tour_guide.'</p>';
}

I hope that this works now.
