問題描述

基于"woocommerce 在結(jié)帳和購(gòu)物車中更改價(jià)格頁面" 回答更改結(jié)帳頁面總價(jià)的代碼，我添加了一些額外的代碼來計(jì)算用戶在購(gòu)物車中擁有的產(chǎn)品，如果用戶在購(gòu)物車中有 9 個(gè)產(chǎn)品，則添加一些價(jià)格總計(jì):

Based on "woocommerce change price in checkout and cart page" answer code that change the total price in checkout page, I have added some extra code to count the products that user have in cart and if user had like 9 products in cart then add some price to total:

add_action( 'woocommerce_before_cart_totals', 'custom_cart_total' , 'get_cart_contents_count');
function custom_cart_total() {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
            return;
    if (WC()->cart->get_cart_contents_count() == 9){
        WC()->cart->total += 15;
    }
    elseif(WC()->cart->get_cart_contents_count() == 6){
       WC()->cart->total += 14; 
    }
    elseif(WC()->cart->get_cart_contents_count() == 4){
       WC()->cart->total += 13; 
    }

}

但它不起作用.這張圖片將說明一切:

如果有人可以更正代碼并告訴我如何顯示圖片中的消息，我將不勝感激

I will appreciate if anyone could correct the code and tell me how can I display the message like in the picture

推薦答案

你最好改用 FEE API，這樣:

You should better use the FEE API instead, this way:

// Add a custom packing fee based on item count
add_action( 'woocommerce_cart_calculate_fees', 'custom_packing_fee', 10, 1 );
function custom_packing_fee( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( did_action( 'woocommerce_cart_calculate_fees' ) >= 2 )
        return;

    $count = $cart->get_cart_contents_count();

    if ( $count >= 9 ){
        $fee = 15;
    }
    elseif( $count >= 6 && $count < 9 ){
        $fee = 14;
    }
    elseif( $count >= 4 && $count < 6 ){
        $fee = 13;
    }

    if ( isset($fee) && $fee > 0 ) {
        $label = sprintf( __('Box fee (%d items)'), $count);
        $cart->add_fee( $label, $fee, false );
    }
}

代碼位于您的活動(dòng)子主題(或活動(dòng)主題)的functions.php 文件中.經(jīng)測(cè)試有效.

Code goes in functions.php file of your active child theme (or active theme). Tested and works.

如果您想為包裝費(fèi)啟用稅金，請(qǐng)將第三個(gè)參數(shù)從 false 更改為 true.

If you want to enable taxes for the packing fee, change the third argument from false to true.
