wc\u打印\u通知在购物车和迷你购物车刷新时重复?(Woocommerce | Wordpress)

1076

我的代码清除了购物车中的任何其他产品,并在将包添加到购物车时只保留包。然后,当包装在购物车中时,它将禁用所有产品的“添加到购物车”按钮。最后,当人们点击灰色的addtocart按钮时,它会改变弹出的错误消息。

我如何确保 wc_print_notice() 在购物车页面只输出一次通知?

// Remove conditionally cart items based on a specific product (item)
    function remove_cart_items_conditionally( $cart ) {
    // HERE define your specific product ID
    $specific_product_id = 1076; 

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $cart_items  = $cart->get_cart(); // Cart items array
    $items_count = count($cart_items); // Different cart items count

    // Continue if cart has at least 2 different cart items
    if ( $items_count < 2 )
        return;

    $last_item    = end($cart_items); // Last cart item data array
    $is_last_item = false; // Initializing

    // Check if the specific product is the last added item
    if ( in_array($specific_product_id, array( $last_item['product_id'], $last_item['variation_id'] ) ) ) {
        $is_last_item = true;
    }

    // Loop through cart items
    foreach ( $cart_items as $cart_item_key => $cart_item ) {
        // Remove all others cart items when specific product ID is the last added to cart
        if ( ! in_array($specific_product_id, array( $cart_item['product_id'], $cart_item['variation_id'] ) ) && $is_last_item ) {
            $cart->remove_cart_item( $cart_item_key );
            wc_print_notice( 'Individual resources have been removed as the full pack already contains all the resources', 'notice' );
        }
    }
}
add_action( 'woocommerce_before_calculate_totals', 'remove_cart_items_conditionally', 10, 1 );

// Disable the add to cart button if specified product is in the cart
function disable_add_to_cart_if_product_is_in_cart ( $is_purchasable, $product ){

    $specific_product_id = 1076;

    // Loop through cart items checking if the product is already in cart
    foreach ( WC()->cart->get_cart() as $cart_item ){
        if ( in_array($specific_product_id, array( $cart_item['product_id'], $cart_item['variation_id'] ) ) ) {
            return false;

        }
    }
    return $is_purchasable;
}
add_filter( 'woocommerce_is_purchasable', 'disable_add_to_cart_if_product_is_in_cart', 10, 2 );

// Change disabled add to cart button popup message to something relevant
function customizing_product_variation_message( $translated_text, $untranslated_text, $domain )
{
    if ( in_array($specific_product_id, array( $cart_item['product_id'], $cart_item['variation_id'] ) ) ) {
        if ($untranslated_text == 'Sorry, this product is unavailable. Please choose a different combination.') {
        $translated_text = __( 'The full pack in the cart already contains this resource', $domain );
        }
    }
    return $translated_text;
}
add_filter( 'gettext', 'customizing_product_variation_message', 10, 3 );

我的代码由以下答案组成:

Remove conditionally Woocommerce cart items based on a specific product

Disable Woocommerce add to cart button if the product is already in cart

Customizing product variations message on single product pages
