获取woocommerce购物车总金额 [英] Get woocommerce carts total amount

问题描述

我正在尝试对购物车的总价施加折扣，但是我只能对商品的基本价格而不是总价进行折扣.我在Google上搜索了一下，发现其中的此帖子 wordpress stackoverflow:

I am trying to apply a discount to a carts total price, but I can only do it to the item base price and not the over all price. I Googled and came across this post in the wordpress stackoverflow:

$ amount = floatval(preg_replace('#[^ \ d.]#'，''， $ woocommerce->购物车-> get_cart_total())); preg_replace消除了 除十进制字符和冒号外的所有内容.

$amount = floatval( preg_replace( '#[^\d.]#', '', $woocommerce->cart->get_cart_total() ) ); The preg_replace eliminates everything but decimal characters and colons.

如果您想用它做数学运算，则floatval会转换值 从字符串到数字.

Should you care to do math with it, the floatval converts the value from a string to a numeric one.

我尝试添加:

$amount2 = floatval( preg_replace( '#[^\d.]#', '', $woocommerce->cart->get_cart_total() ) );

并更改

$discount = round( (($discounting_amount / 100 ) *  $this->amount)*-1, WC()->cart->dp);

到

$discount = round( (($discounting_amount / 100 ) *  $amount2)*-1, WC()->cart->dp);

但是出现以下错误:

Fatal error: Call to a member function get_cart_total() on a non-object in...

推荐答案

您需要调用全局变量以确保其获取正确的值.

You need to call the global variable to ensure that it gets the correct values.

如果添加

 global $woocommerce;

就在

 $amount2 = floatval( preg_replace( '#[^\d.]#', '', $woocommerce->cart->get_cart_total() ) );

应该可以解决您的问题.

that should solve your problem.
