Woocommerce购物车通知显示多次

我有一个正常工作的功能,除了它在购物车中显示两次而不是一次。该功能适用​​折扣并显示通知。该函数查找特定类别的项目添加总计,如果它满足折扣金额,则应用折扣并显示通知。现在,即使购物车中只有一个商品,它也会显示两次通知。

我已尝试添加wc_clear_notices(),但这会清除我需要的其他通知,例如最小订单数量的最大通知。如果我在函数的开头或任何foreach语句中添加wc_clear_notices(),它将在它显示之前清除其他最小/最大通知。

以下是我已经看过的一些问题,但只是说使用wc_clear_notices()因为其他通知被清除而无法使用{<1}}:

WooCommerce Notice, run only once

Show wc_add_notice only one time

以下是我目前拥有的正确折扣商品和显示通知的代码,但会两次显示通知而不是一次:

//apply discounts to foil and seal product categories
add_action( 'woocommerce_before_calculate_totals', 'cart_count_foil_seal_items',10,1);

function cart_count_foil_seal_items( $cart_object ) {
$seal_prod_tally = 0;
$foil_prod_tally = 0;
// Iterating through each item in cart
foreach ( $cart_object->get_cart() as $item_values ) {
    //  Get cart item data
    $item_id = $item_values['data']->get_id(); // Product ID
    $item_qty = $item_values['quantity']; // Item quantity

    // Getting the object
    $product = new WC_Product( $item_id );
    $prod_cat = wp_get_post_terms($product->get_id(),'product_cat',array('fields'=>'slugs'));

    //tally total
    if (in_array('seal-stickers', $prod_cat)){
        $seal_prod_tally += $item_qty;
    }else if(in_array('foil-badges', $prod_cat)){
        $foil_prod_tally += $item_qty;
    }
}

 foreach ( $cart_object->get_cart() as $item_values ) {

    //Get cart item data
    $item_id = $item_values['data']->get_id(); // Product ID
    $item_qty = $item_values['quantity']; // Item quantity

    // Getting the object
    $product = new WC_Product( $item_id );
    $prod_cat2 = wp_get_post_terms($product->get_id(),'product_cat',array('fields'=>'slugs'));        

    //apply discount to each item within category

      if (in_array('seal-stickers',$prod_cat2)){

        switch ($seal_prod_tally){

当客户使用“更新购物车”按钮更新购物车时会导致多个通知,因此每次客户点击“更新购物车”按钮时,快速修复只是清除通知。

最好从源头解决问题,找到一种不同的方式来显示没有重复的通知,但在此之前,这会产生预期的效果。

//clear notices on cart update
function clear_notices_on_cart_update() { 
    wc_clear_notices();
}; 

// add the filter 
add_filter( 'woocommerce_update_cart_action_cart_updated', 'clear_notices_on_cart_update', 10, 1 );

我更喜欢使用 wc_has_notice 来查看消息是否尚未添加。
