检查客户是否购买了东西并将产品添加到 WooCommerce 中的购物车

Check if customer has purchased something and add product to cart in WooCommerce

下面的代码在 WooCommerce 中自动将产品添加到购物车:

add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
    if ( ! is_admin() ) {
        $product_id = 64;
        $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->get_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 );
        }
    }
}

答案 允许使用自定义条件函数检查用户是否已经进行购买 has_bought()

所以我想检查客户之前是否订购过并且:

但是我没有找到在我的代码中使用它的方法。

任何帮助将不胜感激。

下面的代码使用了。它会为新客户和已确认客户自动将不同的产品添加到购物车:

add_action( 'template_redirect', 'add_product_to_cart_conditionally' );
function add_product_to_cart_conditionally() {
    if ( is_admin() )  return; // Exit

    // Below define the product Id to be added:
    $product_A = 37; // <== For new customers that have not purchased a product before (and guests)
    $product_B = 53; // <== For confirmed customers that have purchased a product before

    $product_id = has_bought() ? $product_B : $product_A;

    // If cart is empty
    if( WC()->cart->is_empty() ) {
        WC()->cart->add_to_cart( $product_id ); // Add the product
    }
    // If cart is not empty
    else {
        // Loop through cart items (check cart items)
        foreach ( WC()->cart->get_cart() as $item ) {
            // Check if the product is already in cart
            if ( $item['product_id'] == $product_id ) {
                return; // Exit if the product is in cart
            }
        }
        // The product is not in cart: We add it
        WC()->cart->add_to_cart( $product_id );
    }
}

代码进入活动子主题(或活动主题)的 functions.php 文件。已测试并有效。
