WooCommerce中特定类别的子类别的最小购物车数量

问题描述

我正尝试只允许特定类别（具有一些子类别）或最多4个子类别（coffee1，流行混合，订阅，chaiandchocolate）组合的订单，最高限额为$ 32。

基于Minimum cart amount for specific product categories in WooCommerce的答案代码，这是我的代码：

add_action( 'woocommerce_check_cart_items','check_cart_coffee_items' );
function check_cart_coffee_items() {
    $categories = array('coffee'); // Defined targeted product categories
    $threshold  = 32; // Defined threshold amount

    $cart       = WC()->cart;
    $cart_items = $cart->get_cart();
    $subtotal   = $cart->subtotal;
    $subtotal  -= $cart->get_cart_discount_total() + $cart->get_cart_discount_tax_total();
    $found      = false;

    foreach( $cart_items as $cart_item_key => $cart_item ) {
        // Check for specific product categories
        if ( has_term( $categories,'product_cat',$cart_item['product_id'] ) ) {
            $found = true; // A category is found
            break; // Stop the loop
        }
    }

    if ( $found && $subtotal < $threshold ) {
        // Display an error notice (and avoid checkout)
        wc_add_notice( sprintf( __( "You must order at least %s of coffee" ),wc_price($threshold) ),'error' );
    }
}

但是我无法使它适用于整个咖啡类别或任何单个子类别。欢迎提供帮助。

解决方法

请尝试以下操作，它将检查“咖啡”主类别的所有子类别中的项目（以及包括该子类别中的税款在内的非折扣小计）：

add_action( 'woocommerce_check_cart_items','minimum_order_amount_for_subcategories' );
function minimum_order_amount_for_subcategories() {
    $term_slug   = 'coffee'; // <==  Define the targeted main product category slug
    $threshold   = 32; // <==  Define the minimum amount threshold

    $taxonomy    = 'product_cat'; // WooCommerce product category taxonomy
    $subtotal    = 0; // Itintializing
    $found       = false; // Itintializing
    
    // Get the children terms Ids from the main product category term slug
    $main_term   = get_term_by( 'slug',$term_slug,$taxonomy );
    $childen_ids = get_term_children( $main_term->term_id,$taxonomy );
    $terms_ids   = array_merge( array($main_term->term_id),$childen_ids);
    
    foreach( WC()->cart->get_cart() as $cart_item ) {
        // Check for specific product category children term ids
        if ( has_term( $terms_ids,$taxonomy,$cart_item['product_id'] ) ) {
            $found = true; // At least subcategory is found
            
            // Get non discounted subtotal including taxes from subcategories
            $subtotal += $cart_item['line_subtotal'] + $cart_item['line_subtotal_tax']; 
        }
    }

    if ( $found && $subtotal < $threshold ) {
        // Display an error notice (and avoid checkout)
        wc_add_notice( sprintf(
            __( "You must order at least %s of %s","woocommerce" ),wc_price($threshold),'"<strong>' . ucfirst($term_slug) . '</strong>"' 
        ),'error' );
    }
}

代码进入活动子主题（或活动主题）的functions.php文件中。应该可以。
