Woocommerce 购物车通知多次显示 [英] Woocommerce cart notice showing multiple times

问题描述

我有一个正常工作的功能，除了它在购物车中显示两次通知而不是一次.该函数应用折扣并显示通知.该函数查找特定类别的项目添加总数，如果满足折扣金额，则应用折扣并显示通知.现在，即使购物车中只有一件商品，它也会显示两次通知.

我已经尝试添加 wc_clear_notices() 但这将清除我需要的其他通知，例如类别的最小订单量的最小最大通知.如果我在函数的开头或任何 foreach 语句中添加 wc_clear_notices() ，它会在显示之前清除其他最小/最大通知.

这里有一些我已经看过的问题，但只是说使用 wc_clear_notices() 这不起作用，因为其他通知被清除了:

解决方案

当客户使用更新购物车"按钮更新购物车时会引起多次通知，因此快速解决方法是在客户每次单击更新购物车"按钮时清除通知.

最好从源头解决问题，即找到一种不同的方式来显示通知而不会重复，但在此之前，这会得到预期的效果.

//清除购物车更新通知函数 clear_notices_on_cart_update() {wc_clear_notices();};//添加过滤器add_filter( 'woocommerce_update_cart_action_cart_updated', 'clear_notices_on_cart_update', 10, 1 );

I have a function that's working properly except for it displays the notice twice in the cart instead of once. The function applies a discount and also shows a notice. The function looks for items of a particular category adds the total and if it meets the discount amount it applies the discount and shows a notice. Right now, even if there's only one item in the cart, it's showing the notice twice.

I've tried adding wc_clear_notices() but that will clear other notices I need like min max notices for minimum order amounts on categories. If I add in wc_clear_notices() at the beginning of the function or in any of the foreach statements it will clear the other min/max notice before it even shows.

Here are some questions I've already looked at but just say to use wc_clear_notices() which isn't working because other notices get cleared:

WooCommerce Notice, run only once

Show wc_add_notice only one time

Here's the code I currently have that correctly discounts items and displays notices but displays the notices twice instead of once:

//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)){

解决方案

The multiple notices were caused when the customer updated the cart with the Update Cart button so a quick fix was simply clearing notices every time the customer clicked the Update Cart button.

It would be better to solve the problem at its source which would be finding a different way to display notices without duplication but until then this gets the desired effect.

//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 );
