php 在 WooCommerce 3 中获取订单项目和 WC_Order_Item_Product

Get Order items and WC_Order_Item_Product in WooCommerce 3

提问by Solomon Closson

Ok, reading up on the changes in WooCommerce 3.0+, it seems that you can not access this class directly anymore, so I would assume that this code needs to be changed, since it is spitting out an error:

好的，阅读 WooCommerce 3.0+ 中的更改，您似乎无法再直接访问此类，因此我认为需要更改此代码，因为它正在吐出错误：

$order_item_id = 15;
$order_item = new WC_Order_Item_Product($order_item_id);
$return = $order_item->get_id() ? $order_item : false;

But, embarrassingly, I'm not sure how to change this code to use the correct new getter and setter functions in the newest version of this class, which no longer has a construct. How to do this properly? I don't see any getfunction on getting the order item in the same way as the above.

但是，令人尴尬的是，我不确定如何更改此代码以在该类的最新版本中使用正确的新 getter 和 setter 函数，该版本不再具有构造。如何正确地做到这一点？我没有看到get以与上述相同的方式获取订单项目的任何功能。

Maybe I am overlooking something here?

也许我在这里忽略了一些东西？

If you use the get_id()method, you get your item ID which is 15in your code.

如果您使用该get_id()方法，您将获得您15的代码中的项目 ID 。

Get The WC_Productobject from the order item ID:

WC_Product从订单商品 ID 中获取对象：

$order_item_id = 15;
$item = new WC_Order_Item_Product($order_item_id);

// The product ID
$product_id = $item->get_product_id(); 

// The variation ID
$variation_id = $item->get_variation_id(); 

// The WC_Product object
$product = $item->get_product(); 

// The quantity
$quantity = $item->get_quantity(); 

// The order ID
$order_id = $item->get_order_id(); 

// The WC_Order object
$order = $item->get_order(); 

// The item ID
$item_id = $item->get_id(); // which is your $order_item_id

// The product name
$product_name = $item->get_name(); // … OR: $product->get_name();

// Get the product SKU (using WC_Product method)
$sku = $product->get_sku();

// Get line item totals (non discounted)
$total     = $item->get_subtotal(); // Total without tax (non discounted)
$total_tax = $item->get_subtotal_tax(); // Total tax (non discounted)

// Get line item totals (discounted when a coupon is applied)
$total     = $item->get_total(); // Total without tax (discounted)
$total_tax = $item->get_total_tax(); // Total tax (discounted)

Get the order items from the WC_Orderobject(and use theWC_productObject):

从WC_Order对象中获取订单项（并使用WC_product对象）：

$order_id = 156; // The order_id

// get an instance of the WC_Order object
$order = wc_get_order( $order_id );

// The loop to get the order items which are WC_Order_Item_Product objects since WC 3+
foreach( $order->get_items() as $item_id => $item ){
    //Get the product ID
    $product_id = $item->get_product_id();

    //Get the variation ID
    $variation_id = $item->get_variation_id();

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

    // The quantity
    $quantity = $item->get_quantity();

    // The product name
    $product_name = $item->get_name(); // … OR: $product->get_name();

    //Get the product SKU (using WC_Product method)
    $sku = $product->get_sku();

    // Get line item totals (non discounted)
    $total     = $item->get_subtotal(); // Total without tax (non discounted)
    $total_tax = $item->get_subtotal_tax(); // Total tax (non discounted)

    // Get line item totals (discounted when a coupon is applied)
    $total     = $item->get_total(); // Total without tax (discounted)
    $total_tax = $item->get_total_tax(); // Total tax (discounted)
}

Accessing data and custom meta data:

访问数据和自定义元数据：

1) unprotecting WC_Order_Item_Productdataand custom meta data:

1）取消保护WC_Order_Item_Product数据和自定义元数据：

You can use all WC_Order_Item_Product datamethods or you can unprotect the data using WC_Datafollowing methods:

您可以使用所有WC_Order_Item_Product data方法，也可以使用WC_Data以下方法取消保护数据：

$order_id = 156; // The order_id

// get an instance of the WC_Order object
$order = wc_get_order( $order_id );

// The loop to get the order items which are WC_Order_Item_Product objects since WC 3+
foreach( $order->get_items() as $item_id => $item ){

    // Get the common data in an array: 
    $item_product_data_array = $item->get_data();

    // Get the special meta data in an array: 
    $item_product_meta_data_array = $item->get_meta_data();

    // Get the specific meta data from a meta_key: 
    $meta_value = $item->get_meta( 'custom_meta_key', true );

    // Get all additional meta data (formatted in an unprotected array)
    $formatted_meta_data = $item->get_formatted_meta_data( ' ', true );


    // Get line item totals (non discounted)
    $total     = $item->get_subtotal(); // Total without tax (non discounted)
    $total_tax = $item->get_subtotal_tax(); // Total tax (non discounted)

    // Get line item totals (discounted when a coupon is applied)
    $total     = $item->get_total(); // Total without tax (discounted)
    $total_tax = $item->get_total_tax(); // Total tax (discounted)
}

2) The Array Accessis still possible (for backwards compatibility with legacy arrays)to get the common data directly:

2) Array Access仍然可以（为了与遗留数组向后兼容）直接获取公共数据：

$order_id = 156; // The order_id

// get an instance of the WC_Order object
$order = wc_get_order( $order_id );

// The loop to get the order items which are WC_Order_Item_Product objects since WC 3+
foreach( $order->get_items() as $item_id => $item ){


    $product_id    = $item['product_id']; // Get the product ID
    $variation_id  = $item['variation_id']; // Get the variation ID

    $product_name  = $item['name']; // The product name
    $item_qty      = $item['quantity']; // The quantity

    // Get line item totals (non discounted)
    $line_total     = $item['subtotal']; // or $item['line_subtotal'] -- The line item non discounted total
    $line_total_tax = $item['subtotal_tax']; // or $item['line_subtotal_tax'] -- The line item non discounted tax total

    // Get line item totals (discounted)
    $line_total2     = $item['total']; // or $item['line_total'] -- The line item non discounted total
    $line_total_tax2 = $item['total_tax']; // The line item non discounted tax total

    // And so on ……
}

WC_Order_Item_Product inherits from WC_Order_Item, which has get_order_id(), so you can get the Order ID with

WC_Order_Item_Product 继承自 WC_Order_Item，它有 get_order_id()，所以你可以用

$order_item->get_order_id();
