将变量产品添加到全局允许延期交货命令

Question

是否可以将可变产品添加到延期交货命令中？我以前使用过这个Allow backorders and notify customer for parent product categories in Woocommerce，它工作正常，但代码似乎不适用于可变产品。请帮忙谢谢

要处理产品变化，请尝试以下方法：

// Custom conditional function that checks for parent product categories
function has_parent_term( $product_id ) {
    // HERE define the parent products categories SLUGS in the array
    $categories = array("clothing", "posters"); //  <===  <===  <=== HERE YOUR CATEGORIES SLUGS

    $parent_term_ids = $categories_ids = array(); // Initializing

    // Convert categories term slugs to categories term ids
    foreach ( $categories as $category ){
        $categories_ids[] = get_term_by('slug', $category, 'product_cat')->term_id;
    }

    // Loop through the current product category terms to get only parent main category term
    foreach( get_the_terms( $product_id, 'product_cat' ) as $term ){
        if( $term->parent > 0 ){
            $parent_term_ids[] = $term->parent; // Set the parent product category
        } else {
            $parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
        }
    }
    return array_intersect( $categories_ids, $parent_term_ids ) ? true : false;
}



add_filter( 'woocommerce_product_is_in_stock', 'filter_product_is_in_stock', 10, 2 );
function filter_product_is_in_stock( $is_in_stock, $product ){
    // Here set the products categories in the array (can be terms ids, slugs or names)
    $categories = array("clothing");

    // For product variations
    $product_id = $product->is_type('variation') ? $product->get_parent_id() : $product->get_id();


    if( has_parent_term( $product_id ) ){
        $is_in_stock = true;
    }
    return $is_in_stock;
}

add_filter( 'woocommerce_product_backorders_allowed', 'filter_products_backorders_allowed', 10, 3 );
function filter_products_backorders_allowed( $backorder_allowed, $product_id, $product ){
    // Here set the products categories in the array (can be terms ids, slugs or names)
    $categories = array("clothing");

    // For product variations
    $product_id = $product->is_type('variation') ? $product->get_parent_id() : $product_id;

    if( has_parent_term( $product_id ) ){
        $backorder_allowed = true;
    }
    return $backorder_allowed;
}

add_filter( 'woocommerce_product_backorders_require_notification', 'filter_product_backorders_require_notification', 10, 2 );
function filter_product_backorders_require_notification( $notify, $product ){
    // Here set the products categories in the array (can be terms ids, slugs or names)
    $categories = array("clothing");

    // For product variations
    $product_id = $product->is_type('variation') ? $product->get_parent_id() : $product->get_id();

    if( has_parent_term( $product_id ) ){
        $notify = true;
    }
    return $notify;
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。
