在 WooCommerce 3 中将产品添加到购物车时有条件地添加订阅

Question

您好，我正在寻找一个代码，如果添加了普通产品但 NOT，则可以将我的订阅 ID (2282) 添加到购物车如果用户已经是订阅者。

欢迎提问。我在 GMT+1 时区

WordPress - 4.8.1
WooCommerce – 3.1.1
WooCommerce 订阅 - 2.2.11
WooCommerce 会员资格 – 1.8.8
主题 - 店主 - 2.2.3

我已经看过并试图用它来搞笑。没有成功

// add item to cart on visit
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
    if ( ! is_admin() ) {
        $product_id = 2282;
        $found = false;
        //check if product already in cart
        if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
            foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
                $_product = $values['data'];
                if ( $_product->id == $product_id )
                    $found = true;
            }
            // if product not found, add it
            if ( ! $found )
                WC()->cart->add_to_cart( $product_id );
        } else {
            // if no products in cart, add it
            WC()->cart->add_to_cart( $product_id );
        }
    }
}

当产品添加到非活跃订阅者的购物车时，如何有条件地添加订阅？

Answer 1

对于 WooCommerce 订阅我没有找到任何功能来检查当前用户是否有有效订阅。

所以我做了这个仍然适用于 WooCommerce 3+ 和最后一个 WC 订阅插件的答案：

因此，使用挂接到 woocommerce_add_to_cart 操作挂钩中的自定义函数并使用我旧答案中的条件函数代码，您将使其正常工作：

// Conditional function detecting if the current user has an active subscription
function has_active_subscription( $user_id=null ) {
    // if the user_id is not set in function argument we get the current user ID
    if( null == $user_id )
        $user_id = get_current_user_id();

    // Get all active subscrptions for a user ID
    $active_subscriptions = get_posts( array(
        'numberposts' => -1,
        'meta_key'    => '_customer_user',
        'meta_value'  => $user_id,
        'post_type'   => 'shop_subscription', // Subscription post type
        'post_status' => 'wc-active', // Active subscription
    ) );
    // if user has an active subscription
    if(!empty($active_subscriptions)) return true;
    else return false;
}


// Conditionally checking and adding your subscription when a product is added to cart
add_action( 'woocommerce_add_to_cart', 'add_subscription_to_cart', 10, 6 );
function add_subscription_to_cart( $cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data ) {

    // Here define your subscription product
    $subscription_id = 2282;
    $found = false;

    if ( is_admin() || has_active_subscription() || $product_id == $subscription_id ) return;  // exit

    // Checking if subscription is already in cart
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        if ( $cart_item['product_id'] == $subscription_id ){
            $found = true;
            break;
        }
    }
    // if subscription is not found, we add it
    if ( ! $found )
        WC()->cart->add_to_cart( $subscription_id );
}

代码进入任何插件 php 文件（钩子可以在活动主题的 function.php 文件中使用）。

代码已经过测试并且有效。

如果订阅从购物车中删除，我们将在结帐时重新检查：

add_action( 'woocommerce_before_checkout_form', 'check_subscription_in_checkout', 10, 0 );
function check_subscription_in_checkout() {

    // Here define your subscription product
    $subscription_id = 2282;
    $found = false;

    if ( is_admin() || has_active_subscription() || ! is_checkout() ) return;  // exit

    // Checking if subscription is already in cart
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        if ( $cart_item['product_id'] == $subscription_id ){
            $found = true;
            break;
        }
    }
    // if subscription is not found, we add it
    if ( ! $found )
        WC()->cart->add_to_cart( $subscription_id );
}
