問題描述

我的 WP 網站銷售定制 T 恤.定制插件使每件定制襯衫成為 woocommerce 購物車中的一個行項目.如果訂購了 2 件一件設計的襯衫(該訂單項的數量為 2 件)，我想打折.但如果每行只有 1 件商品，我不想打折.

我找到了這個解決方案

要顯示折扣產品價格而不是原始產品價格，只需刪除woocommerce_cart_item_price()函數(和鉤子)...

最新類似: Woocommerce 3 中的購物車項目數量累進百分比折扣

My WP site sells customized t-shirts. The customization plugin makes each customized shirt a line item in the woocommerce cart. If there are 2 shirts ordered of one design (quantity of 2 on that line item) I want to discount. But if there is just 1 item per line I dont want to discount.

I found this solution

Adding a discount by cart items conditionally based on the item quantity

But this seems to change the product price in the db, so after the discount kicks in for say 2 blue shirts because there were 2 ordered on 1 line, if I add a 3rd shirt on a separate line it also gets the discount, which I dont want.

Since woocommerce version 3+ the linked answer code doesn't work. It needs something different and can even be done in a better way.

The code will apply a cart item discount based on the cart item quantity. In this code example, it will apply a discount of 5% on the cart item, when the quatity is equal or more than 2 (two).

The cart item unit price displayed is always the real product price. The discount will be effective and displayed on the cart item subtotal.

Additionally the product name will be appended with a discount mention.

The code:

add_filter('woocommerce_add_cart_item_data', 'add_items_default_price_as_custom_data', 20, 3 );
function add_items_default_price_as_custom_data( $cart_item_data, $product_id, $variation_id ){
    $product_id = $variation_id > 0 ? $variation_id : $product_id;

    ## ----- YOUR SETTING ----- ##
    $discount_percentage = 5; // Discount (5%)

    // The WC_Product Object
    $product = wc_get_product($product_id);

    // Only for non on sale products
    if( ! $product->is_on_sale() ){
        $price = (float) $product->get_price();

        // Set the Product default base price as custom cart item data
        $cart_item_data['base_price'] = $price;

        // Set the Product discounted price as custom cart item data
        $cart_item_data['new_price'] = $price * (100 - $discount_percentage) / 100;

        // Set the percentage as custom cart item data
        $cart_item_data['percentage'] = $discount_percentage;
    }

    return $cart_item_data;
}

// Display the product original price
add_filter('woocommerce_cart_item_price', 'display_cart_items_default_price', 20, 3 );
function display_cart_items_default_price( $product_price, $cart_item, $cart_item_key ){
    if( isset($cart_item['base_price']) ) {
        $product        = $cart_item['data'];
        $product_price  = wc_price( wc_get_price_to_display( $product, array( 'price' => $cart_item['base_price'] ) ) );
    }
    return $product_price;
}

// Display the product name with the discount percentage
add_filter( 'woocommerce_cart_item_name', 'append_percetage_to_item_name', 20, 3 );
function append_percetage_to_item_name( $product_name, $cart_item, $cart_item_key ){
    if( isset($cart_item['percentage']) && isset($cart_item['base_price']) ) {
        if( $cart_item['data']->get_price() != $cart_item['base_price'] )
            $product_name .= ' <em>(' . $cart_item['percentage'] . '% discounted)</em>';
    }
    return $product_name;
}

add_action( 'woocommerce_before_calculate_totals', 'custom_discounted_cart_item_price', 20, 1 );
function custom_discounted_cart_item_price( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

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

    ## ----- YOUR SETTING ----- ##
    $targeted_qty = 2; // Targeted quantity

    // Loop through cart items
    foreach ( $cart->get_cart() as $cart_item ) {

        // For item quantity of 2 or more
        if( $cart_item['quantity'] >= $targeted_qty && isset($cart_item['new_price']) ){

            // Set cart item discounted price
            $cart_item['data']->set_price($cart_item['new_price']);
        }
    }
}

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

To display the discounted product price instead of the original product price, just remove woocommerce_cart_item_price() function (and hook)…
