更改 woocommerce 订单总重量 [英] Change total woocommerce order weight

问题描述

我需要更改 woocommerce 网站中订单的总重量.

I need change total weight of order in woocommerce website.

例如:我的购物车中有 3 个产品:1 - 30g；2 - 35；3 - 35 克；总计 = 30+35+35 = 100g，但我想将包裹重量添加到总重量(占总重量的 30%).

For example: I have a 3 product in a cart: 1 - 30g; 2 - 35; 3 - 35g; total = 30+35+35 = 100g, but I want to add package weight to total weight (30% from total weight).

示例:((30+35+35) * 0.3) + (30+35+35) = 130g

Example: ((30+35+35) * 0.3) + (30+35+35) = 130g

我可以计算出来，但是如何将总重量从 100g 更改为 130g.

I can calculate it, but how change total weight from 100g to 130g.

为了获得总重量，我使用 get_cart_contents_weight()，但我不知道如何设置新值.

For getting total weight I use get_cart_contents_weight(), but I don't know how to set new value.

推荐答案

Hook in the right filter action

让我们看看函数get_cart_contents_weight():

public function get_cart_contents_weight() {
    $weight = 0;

    foreach ( $this->get_cart() as $cart_item_key => $values ) {
        $weight += $values['data']->get_weight() * $values['quantity'];
    }

    return apply_filters( 'woocommerce_cart_contents_weight', $weight );
}

我们可以使用一个过滤器钩子:woocommerce_cart_contents_weight

There is a filter hook we can use: woocommerce_cart_contents_weight

所以我们可以给这个过滤器添加一个函数:

So we can add a function to this filter:

add_filter('woocommerce_cart_contents_weight', 'add_package_weight_to_cart_contents_weight');

function add_package_weight_to_cart_contents_weight( $weight ) {        
    $weight = $weight * 1.3; // add 30%     
    return $weight;     
}

要单独为每个产品添加包裹重量，您可以试试这个:

---

To add the package weight to every product separately, you can try this:

add_filter('woocommerce_product_get_weight', 'add_package_to_product_get_weight');

function add_package_to_product_get_weight( $weight ) {
    return $weight * 1.3;
}

但不要同时使用这两种解决方案.

But do not use both solutions together.
