php - 在 WooCommerce 中设置除产品标签外的最小订单值

Question

我目前有一个 wordpress 网站，为我的 WooCommerce 商店设置了最低订单值，在我的functions.php 中设置，它运行良好。我现在想设置一个产品标签作为此规则的异常(exception)，并且没有最低订单值(value)……这可能吗？
我实际上正在使用 Set a minimum order amount in WooCommerce答案代码。
不确定更改为“wc 最小订单量”等插件是否可以解决问题，或者是否可以将其添加到现有代码中？
非常感谢任何建议!

要使此代码对特定产品标签无效，请使用以下内容:

add_action( 'woocommerce_check_cart_items', 'required_min_cart_subtotal_amount' );
function required_min_cart_subtotal_amount() {

    $minimum_amount = 35; // HERE Set minimum cart total amount
    $product_tags   = array('Lewis'); // HERE set the product tags (term names, slugs or Ids)
    $cart_subtotal  = WC()->cart->subtotal; // Total (before taxes and shipping charges)
    $tag_found      = false;
    
    // Loop through cart items
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        // Check for product tag
        if( has_term( $product_tags, 'product_tag', $cart_item['product_id'] ) ) {
            $tag_found = true;
            break;
        }
    }

    // Add an error notice is cart total is less than the minimum required
    if( $cart_subtotal < $minimum_amount && ! $tag_found ) {
        // Display an error message
        wc_add_notice( '<strong>' . sprintf( __("A minimum total purchase amount of %s is required to checkout."), wc_price($minimum_amount) ) . '<strong>', 'error' );
    }
}

或者，如果您想从购物车小计使用中排除特定产品标签:

add_action( 'woocommerce_check_cart_items', 'required_min_cart_subtotal_amount' );
function required_min_cart_subtotal_amount() {

    $minimum_amount = 35; // HERE Set minimum cart total amount
    $product_tags   = array('Disc'); // HERE set the product tags (term names, slugs or Ids)
    $cart_subtotal  = 0; // Total (before taxes and shipping charges)

    // Loop through cart items
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        // Check for product tag
        if( ! has_term( $product_tags, 'product_tag', $cart_item['product_id'] ) ) {
            $cart_subtotal += $cart_item['line_subtotal'] + $cart_item['line_subtotal_tax'];
        }
    }

    // Add an error notice is cart total is less than the minimum required
    if( $cart_subtotal < $minimum_amount ) {
        // Display an error message
        wc_add_notice( '<strong>' . sprintf( __("A minimum total purchase amount of %s is required to checkout."), wc_price($minimum_amount) ) . '<strong>', 'error' );
    }
}

代码位于事件子主题(或事件主题)的 functions.php 文件中。测试和工作。
