WooCommerce 根据其他变体库存的数量更新产品变体库存状态

Question

早安，

我的产品有 4 种变体（由“尺寸”属性制成的变体）：小号、中号、大号和全套（全部 3 种尺寸）。人们可以选择只购买单一尺码或购买包含全部 3 种尺码的套装（所有 4 种款式的价格不同）。

我只为 3 种尺寸变体（小、中、大）选择了库存管理（允许延期交货），而对于设置变体，我只选择了库存状态为“有货”。我需要根据尺寸变化的库存数量自动更改设置变化库存状态。

当我有 1 个小号、1 个中号和 1 个大号时，我显然还有一套库存。但是，例如，当有人购买小的时，我就没有全套了。我想自动将 Set 变体的库存状态更新为“延期交货”。此外，另一种方法是，当有人购买完整的 Set 时，会自动将 Small、Medium 和 Large 的库存数量更新为 -1。

SMALL - 1x in stock
MEDIUM - 1x in stock
LARGE - 1x in stock
FULL SET - stock status: 'in stock' (only 'in-stock' when there is at least 1 of each; small, medium, large)

当有人购买全套时：

SMALL - 1x in stock -1 = 0x in stock
MEDIUM - 1x in stock -1 = 0x in stock
LARGE - 1x in stock -1 = 0x in stock
FULL SET - stock status: 'on backorder' (only 'in-stock' when there is at least 1 of each; small, medium, large)

所有产品都使用了这些变体，它们不会改变。

虚拟代码可能是这样的（这绝对行不通，我只是想从很多互联网搜索中收集一些东西）：

设置全套库存状态：

function fullset_custom_stockstatus (){
    global $product;
    // Get the available variations
    $available_variations = $product->get_available_variations();

    // Get the term slugs
    $attribute_slug = $values['attributes']['attribute_pa_headcover-size'];
    $wp_term = get_term_by( 'slug', $attribute_slug, 'pa_headcover-size' );
    $term_slug = $wp_term->slug; // Headcover Size Slug 

    // Get the variation quantity
    $variation_obj = wc_get_product( $values['variation_id'] );
    $stock_qty = $variation_obj->get_stock_quantity(); // Stock qty

    //Seperate variation stock data
    $var_small = $term_slug['small'].$stock_qty;
    $var_medium = $term_slug['medium'].$stock_qty;
    $var_large = $term_slug['large'].$stock_qty;

    $var_fullset = $term_name['full-set'].$stock_status;
    
    //Check if each variation stock is 1 or more
    if ($var_small == 0 || $var_medium == 0 || $var_large == 0){
        $var_fullset = 'on-backorder';
    }
    else{
        $var_fullset = 'in-stock';
    }
}
add_action( 'woocommerce_order_item_quantity', 'fullset_custom_stockstatus');

购买全套时更新变化数量：

function update_stockqty_after_fullset_order (){

    //Get the order information
    $order = wc_get_order( $order_id );
    foreach( $order->get_items() as $item ){
        $order_product_id = $item->get_product_id();
        $order_variation_id = $item->get_variation_id();

        //Get the order variation information
        $order_variation = wc_get_product($order_variation_id);
        $order_variation_attribs = $order_variation->get_variation_attributes();
        
        //Check if order variation is 'full-set'
        if ($order_variation_attribs !== 'full-set' ){

            //Get the order product variation information
            $product = wc_get_product( $order_product_id );
            $variations = $product->get_available_variations();

            // Get the term slugs
            $attribute_slug = $values['attributes']['attribute_pa_headcover-size'];
            $wp_term = get_term_by( 'slug', $attribute_slug, 'pa_headcover-size' );
            $term_slug = $wp_term->slug; // Headcover Size Slug 

            // Get the variation quantity
            $variation_obj = wc_get_product( $values['variation_id'] );
            $stock_qty = $variation_obj->get_stock_quantity(); // Stock qty

            //Seperate variation stock data
            $var_small = $term_slug['small'].$stock_qty;
            $var_medium = $term_slug['medium'].$stock_qty;
            $var_large = $term_slug['large'].$stock_qty;

            //Update the stock quanities
            wc_update_product_stock( $var_small, 'decrease' ); 
            wc_update_product_stock( $var_medium, 'decrease' ); 
            wc_update_product_stock( $var_large, 'decrease' ); 

            // Clear/refresh the variation cache (optionally if needed)
            wc_delete_product_transients($variation['variation_id']);

        } else {
         return;
        }
    }
}
add_action( 'woocommerce_order_status_processing', 'update_stockqty_after_fullset_order');

任何帮助将不胜感激。

您可以使用woocommerce_order_status_processing钩子，当订单状态更改为wc-processing时激活。

更新

“全套”变体仅在以下情况下更新：

1. 至少购买了一种“小”、“中”或“大”变体
2. “小”、“中”、“大”变体的最小库存量小于“全套”变体的库存量

这样，根据“小”、“中”、“大”的库存数量，“全套”变体的库存数量将等于最低可售数量变化。

当“全套”变体的库存数量小于或等于零时，启用延期交货。

add_action( 'woocommerce_order_status_processing', 'update_stock_quantity_product', 999, 2 );
function update_stock_quantity_product( $order_id, $order ) {

    foreach ( $order->get_items() as $item_id => $item_data ) {

        if ( ! $product->is_type( 'variation' ) ) {
            continue;
        }

        // initializes the array that will contain the quantity stocks of "small", "medium" and "large" products
        $min_stock = array();

        foreach ( $variation_attributes as $attribute_value ) {

我已经测试了代码并且它可以工作。代码进入主题的functions.php。
