我试图根据我在Woocommerce购物车上进行的一些计算来增加费用,但我想将其从增值税中排除.这是我的代码:
I try to add fees based on some calculations I do on Woocommerce cart, but I want to exclude it from VAT. This is my code:
function woo_add_cart_fee( $cart ) { global $woocommerce; $bookable_total = 0; foreach(WC()->cart->get_cart() as $cart_item_key => $values) { $_product = $values['data']; //doing my stuff to calculate $fee variable WC()->cart->add_fee( 'Fees: ', $fee, false, '' ); //WC()->cart->add_fee( 'Fees: ', $fee, true, '' ); //WC()->cart->add_fee( 'Fees: ', $fee, false, 'zero rate' ); //WC()->cart->add_fee( 'Fees: ', $fee, true, 'zero rate' ); } add_action( 'woocommerce_cart_calculate_fees', 'woo_add_cart_fee' );我尝试了所有评论版本,每个版本也都包含有增值税的费用.
I have tried all the commented versions and each of them includes a VAT on Fees too.
有什么想法可以实现吗?
Any idea how I can achieve it?
推荐答案(更新):带有 add_fee()方法
(Update): TAX OPTIONS with add_fee() method
重要提示:使用 add_fee()方法 取决于woocommerce中的您的第一笔税收设置.由于您的问题不知道,您的税金设置是什么,因此无法帮助您(每个电子商务的税金设置可能会大不相同网站).
IMPORTANT: The fact that TAX is working or not with add_fee() method depends first of your tax settings in woocommerce. As you have not tell in your question what are your TAX settings, It's not possible to help you (Tax settings can be much more different for each e-commerce web site).
例如,如果您要使用零税率"税种,但您尚未为客户所在国家/地区定义正确的零税率"税种,则尝试使用此方法将不起作用配合使用: WC()->cart->add_fee( 'Fees: ', $fee, true, 'zero rate' ); …取决于您的全局税设置.
For example if you want to use 'zero rate' tax class, but you haven't defined the correct 'zero rate' tax class for the customer country, this will not work if you try to use it with: WC()->cart->add_fee( 'Fees: ', $fee, true, 'zero rate' ); … depending on your global tax settings.
以下是真实结帐总计的屏幕截图,其中购物车中有3件商品(使用下面的代码):
Here is a screenshot of REAL checkout totals, for 3 items in cart (using the code below):
类WC_Cart add_fee()方法,向购物车添加了额外费用. add_fee( string $name, float $amount, boolean $taxable = false, string $tax_class = '' )
Parameters: $name Unique name for the fee. Multiple fees of the same name cannot be added. $amount Fee amount. $taxable (default: false) Is the fee taxable? $tax_class (default: '') The tax class for the fee if taxable. A blank string is standard tax class.
原始答案 (更新代码):
您的主要问题位于此行: global $woocommerce, $bookable_total = 0;
Your main problem is in this line: global $woocommerce, $bookable_total = 0;
我们现在可以在函数外定义 $bookable_total变量值.
We can defined now $bookable_total variable value outside the function.
这是您的代码的有效示例:
// This variable value is passed to our function $bookable_total = 1; function woo_add_cart_fee( $bookable_total = 0 ) { global $bookable_total; if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return; // just for this example $item_count = 0; $item_fee = 5; // going through each cart items foreach( WC()->cart->get_cart() as $values ) { $item = $values['data']; if ( empty( $item ) ) break; // getting the cart item_id $item_id = $item->id; $item_count++; // your calculations } // We test $bookable_total value, defined to '1' outside our function // and to 'O' if not defined outside (in this case the fee will be '0') $fee = $item_count * $bookable_total * $item_fee; // add_fee method (TAX will NOT be applied here) WC()->cart->add_fee( 'Fees: ', $fee, false ); } add_action( 'woocommerce_cart_calculate_fees','woo_add_cart_fee' );此代码已经过测试,可以正常工作. 它会出现在您活动的子主题或主题的function.php文件中.
如果未在外部定义 $bookable_total变量,则该值为 0 .
If the $bookable_total variable is not defined outside, the value will be 0.
注意:最好通过以下方式获取$ items ID: $item = $values['data']; $item_id = $item->id;
Note: is better to get the $items ids with: $item = $values['data']; $item_id = $item->id;
参考: Class WC_Cart- add_fee( $name, $amount, $taxable = false, $tax_class = '' ) 方法
Reference: Class WC_Cart - add_fee( $name, $amount, $taxable = false, $tax_class = '' ) method
