Change cart item prices in Woocommerce 3
提问by Archana
I am trying to change product price in cart using the following function:
我正在尝试使用以下功能更改购物车中的产品价格：
add_action( 'woocommerce_before_shipping_calculator', 'add_custom_price'
);
function add_custom_price( $cart_object ) {
foreach ( $cart_object->cart_contents as $key => $value ) {
$value['data']->price = 400;
}
}
It was working correctly in WooCommerce version 2.6.x but not working anymore in version 3.0+
它在 WooCommerce 2.6.x 版中正常工作，但在 3.0+ 版中不再工作
How can I make it work in WooCommerce Version 3.0+?
我怎样才能让它在 WooCommerce 3.0+ 版中工作？
Thanks.
谢谢。

With WooCommerce version 3.0+you need:
使用WooCommerce 3.0+ 版，您需要：
- To use
woocommerce_before_calculate_totalshook instead. - To use WC_Cart
get_cart()method instead - To use WC_product
set_price()method instead
- 改用
woocommerce_before_calculate_totals钩子。 - 改用WC_Cart
get_cart()方法 - 改用WC_product
set_price()方法
Here is the code:
这是代码：
add_action( 'woocommerce_before_calculate_totals', 'add_custom_price', 20, 1);
function add_custom_price( $cart ) {
// This is necessary for WC 3.0+
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Avoiding hook repetition (when using price calculations for example)
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Loop through cart items
foreach ( $cart->get_cart() as $item ) {
$item['data']->set_price( 40 );
}
}
The Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
代码位于活动子主题（或主题）的 function.php 文件中或任何插件文件中。
This code is tested and works.
此代码经过测试并有效。
Note:you can increase the hook priorityfrom
20to1000(or even2000)when using some few specific plugins or others customizations.
注意：您可以将钩子优先级从
20to （甚至10002000)当使用一些特定的插件或其他自定义。

With WooCommerce version 3.2.6, @LoicTheAztec's answer works for me if I increase the priority to 1000.
使用 WooCommerce 3.2.6 版，如果我将优先级提高到 1000，@LoicTheAztec 的答案对我有用。
add_action( 'woocommerce_before_calculate_totals', 'add_custom_price', 1000, 1);
add_action( 'woocommerce_before_calculate_totals', 'add_custom_price', 1000, 1);
I tried priority values of 10,99and 999but the price and total in my cart did not change (even though I was able to confirm with get_price()that set_price()had actually set the price of the item.
我试过的优先级值10，99并且999但在我的车的价格和总没有变化（即使我能够证实与get_price()那set_price()实际上已经设置的项目的价格。
I have a custom hook that adds a fee to my cart and I'm using a 3rd party plugin that adds product attributes. I suspect that these WooCommerce "add-ons" introduce delays that require me to delay my custom action.
我有一个自定义挂钩，可以向我的购物车添加费用，并且我正在使用添加产品属性的 3rd 方插件。我怀疑这些 WooCommerce“附加组件”会导致延迟，需要我延迟自定义操作。
