如何在WooCommerce中设置和更新同类产品的动态库存

Question

问题:我有三个产品相似的类型或他们是相同的(相同的产品，不同的名称)。如果这些产品应该有相同的库存。我不确定这是否可能？

例如：

Product One Stock= 10
Product Two Stock= 10
Product Three Stock= 10

目标：希望为这些产品设置/更新相同的库存(如果其中任何一个是有序的)

结果1:产品1 qty 5按顺序更新新库存

Product One Stock = 10-5 =5
Product Two Stock  = 10-5=5
Product Three Stock = 10-5=5

结果2:产品1 qty 5和产品2 qty 2按顺序排列，因此同类产品=5+2=7的总数量如此更新

Product One Stock = 10-7 =3
Product Two Stock = 10-7=3
Product Three Stock = 10-7=3

为了实现这一点，我在一个选项中设置了所有类似的产品，比如12,45,133 (产品ID)，用逗号ANd分隔，这是公共数量的一个选项字段。

我的密码，我正在尝试的

add_action( 'woocommerce_thankyou', 'set_dynamic_quantity');
function set_dynamic_quantity_having_product_id_in_order($order_id){
    $order  = wc_get_order( $order_id );    
    $items = $order->get_items();
    //getting options value 
    $similar_product_options = get_option( 'similar_product_options_name' ); // Array of All Options
    $vpm_similar_product = $similar_product_options['vpm_similar_product']; //get similar product
    $vpm_similar_product_qty = $similar_product_options['vpm_similar_product_qty']; //get dynamic qty = 100


    $similar_id = explode( ",", $vpm_similar_product );


    //auto update qty if product in order 
    if(in_array( $order->get_items() , $similar_id )){
        foreach ( $items as $item => $value ) {
            $quantity = $item->get_quantity();
            $new_qty = $vpm_similar_product_qty - $quantity;
            //set new quantity to all similar product set in 
            $vpm_similar_product_qty['vpm_similar_product_qty'] = $new_qty;

            foreach ( $similar_id as $item_id => $item_data ) {
                update_meta_data( '_qty', $new_qty, $item_id );
                update_option('vpm_similar_product_qty',$same_type_product);
            }
        }
    }
}

Answer 1

我假设$vpm_similar_product_qty是一个逗号分隔的产品ID。我还假设您只需使用options数组通过update_option更新此值。

这里提出的逻辑是：

1. 循环遍历订单项
2. 对于每一项订单，请检查是否在“双胞胎”列表中。
3. 累积订购量
4. 从同步数量设置值中减少总数量
5. 循环“双胞胎”并相应地更新其数量

这是一个提供的解决方案：

add_action( 'woocommerce_thankyou', 'set_dynamic_quantity_having_product_id_in_order');
function set_dynamic_quantity_having_product_id_in_order($order_id){
    $order  = new WC_Order( $order_id );

    # This protect from double reduction on the same order
    if (get_post_meta($order->get_id(), 'shared_products_quantities_updated', true)) return;


    $similar_product_options = get_option( 'similar_product_options_name' ); // Array of All Options
    $vpm_similar_product = $similar_product_options['vpm_similar_product']; //get similar product
    $shared_stock_products = explode( ",", $vpm_similar_product );

    // Local Testing $shared_stock_products = array(48, 45, 41);

    # First time, set stock level
    if (!get_option('vpm_similar_product_qty')) update_option('vpm_similar_product_qty', 100);

    # Get Shared stock level
    $vpm_similar_product_qty = get_option('vpm_similar_product_qty');

    # Count how many twin products bought
    $reduce_quantity = 0;
    foreach ($order->get_items() as $key => $item){
        if ( in_array($item['product_id'], $shared_stock_products ) ){
            $reduce_quantity += $item->get_quantity();
        }
    }

    # Sync stock levels according to the shared stock level setting
    $updated_quantity = $vpm_similar_product_qty - $reduce_quantity;
    foreach ($shared_stock_products as $product_id){
        $product = new WC_Product($product_id);
        $product->set_stock_quantity(  $updated_quantity );
        $product->save();
    }


    # Prevent duplicate qty deduction
    add_post_meta($order->get_id(), 'shared_products_quantities_updated', true);


    # Sync back the quantity to the shared quantity
    update_option('vpm_similar_product_qty', $updated_quantity);

}

--有一个问题你没有报道：

共享股票为10。两种“孪生”产品在购物车中，一种是8的，一种是5的。这将产生一个负的股票价值。但是，由于这个问题不在这个范围之内，我将不谈这个问题。
