特定Woocommerce产品类别项目的强制性优惠券代码 [英] Mandatory Coupon code for specific Woocommerce product category items

问题描述

在Woocommerce中，我试图为特定类别的所有产品强制设置优惠券代码。

In Woocommerce, I'm trying to make a Coupon Code mandatory for all Products from a specific Category.

以下代码（放置在functions.php中）效果很好，但是无论产品类别如何，所有产品都必须使用优惠券代码：

The following code (placed in functions.php) works well, but makes Coupon Codes mandatory for all Products regardless of the product category:

add_action('woocommerce_check_cart_items', 'make_coupon_code');

function make_coupon_code()
{
    global $woocommerce;
    if(is_cart() || is_checkout()){
        $my_coupon = $woocommerce->cart->applied_coupons;
        echo $woocommerce->cart->get_applied_coupons;
        if(empty($my_coupon))
        {
            wc_add_notice( '<strong>' . $btn['label'] . '</strong> ' . __( 'insert coupon code', 'woocommerce' ), 'error' );
        }
    }
}

有什么想法吗？

（我要定位的产品类别是'chef-masterclass'）

推荐答案

已更新：下面的代码将防止结帐需要用于特定产品类别的强制性优惠券代码：

Updated: The code below will prevent checkout for a mandatory coupon code that need to be applied for a specific product category:

add_action( 'woocommerce_check_cart_items', 'mandatory_coupon_code' );
function mandatory_coupon_code() {
    // HERE below -- Your settings
    $mandatory_coupon   = 'summer'; // <== Coupon code
    $product_categories = array( 'chef-masterclass' ); // <== Product category (Id, slug or name)

    $applied_coupons = WC()->cart->get_applied_coupons();

    // If coupon is found we exit
    if( in_array( $mandatory_coupon, $applied_coupons ) ) return;

    $found = false;

    // Loop through cart items to check for the product category
    foreach ( WC()->cart->get_cart() as $cart_item ){
        if( has_term( $product_categories, 'product_cat', $cart_item['product_id'] ) ){
            $found = true; // cart item from the product category is found
            break; // We can stop the loop
        }
    }

    // Coupon not applied and product category found
    if( $found ){
        // Display an error notice preventing checkout
        $coupon_html = '<strong>"' . ucfirst( $mandatory_coupon ) . '"</strong>';
        $message = sprintf( __( 'Please enter the coupon code %s to checkout.', 'woocommerce' ), $coupon_html );
        wc_add_notice( $message, 'error' );
    }
}

代码会出现在您活跃孩子的function.php文件中主题（或活动主题）。经过测试并有效

Code goes in function.php file of your active child theme (or active theme). Tested and works
