我已经在WooCommerce上创建了一个产品,并使用挂钩woocommerce_before_add_to_cart_button
.在产品详细信息页面上添加了two options现在,当客户从产品详细信息页面将产品添加到购物车时,他们有两个选项。他们可以从这两个选项中选择一个。
然后,我使用woocommerce钩子woocommerce_add_cart_item_data将用户选择的值存储在购物车meta中。
我使用了这个答案中的代码:Save product custom field radio button value in cart and display it on Cart page
这是我的代码:
// single Product Page options
add_action("woocommerce_before_add_to_cart_button", "options_on_single_product");
function options_on_single_product(){
$dp_product_id = get_the_ID();
$product_url = get_permalink($dp_product_id);
?>
<input type="radio" name="custom_options" checked="checked" value="option1"> option1<br />
<input type="radio" name="custom_options" value="option2"> option2
<?php
}
//Store the custom field
add_filter( 'woocommerce_add_cart_item_data', 'save_custom_data_with_add_to_cart', 10, 2 );
function save_custom_data_with_add_to_cart( $cart_item_meta, $product_id ) {
global $woocommerce;
$cart_item_meta['custom_options'] = $_POST['custom_options'];
return $cart_item_meta;
}
这就是我尝试过的:
add_action( 'woocommerce_before_calculate_totals', 'add_custom_price', 10, 1);
function add_custom_price( $cart_obj ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
foreach ( $cart_obj->get_cart() as $key => $value ) {
$product_id = $value['product_id'];
$custom_options = $value['custom_options'];
$coupon_code = $value['coupon_code'];
if($custom_options == 'option2')
{
if($coupon_code !='')
{
global $woocommerce;
if ( WC()->cart->has_discount( $coupon_code ) ) return;
(WC()->cart->add_discount( $coupon_code ))
//code for second discount
}
else{
$percentage = get_post_meta( $product_id , 'percentage', true );
//print_r($value);
$old_price = $value['data']->regular_price;
$new_price = ($percentage / 100) * $old_price;
$value['data']->set_price( $new_price );
}
}
}
}
现在我想从最后一段代码中得到的是:
但它并没有像预期的那样工作,因为更改后的产品价格是maid之前,并且在更改后的价格上应用优惠券折扣。
我想要的是,优惠券折扣将首先适用于产品的常规价格,然后改变这个价格与我的自定义产品折扣。
这个是可能的吗?我怎样才能做到这一点呢?
谢谢。

使用WC_Cart->add_fee()
方法添加负费用对我来说是行不通的。当我检查WC Cart类时,它甚至指出您不允许使用负的ammount。
我做了以下工作:
woocommerce_get_shop_coupon_data
,并将您想要的该filter的所有优惠券数据设置到woocommerce_before_calculate_totals
中,然后将您的自定义优惠券设置到购物车中。woocommerce_cart_totals_coupon_label
对其进行更改。示例函数:
/**
* NOTE: All the hooks and filters below have to be called from your own
* does_it_need_custom_discount() function. I used the 'wp' hook for mine.
* Do not copy/paste this to your functions.php.
**/
add_filter('woocommerce_get_shop_coupon_data', 'addVirtualCoupon', 10, 2);
function addVirtualCoupon($unknown_param, $curr_coupon_code) {
if($curr_coupon_code == 'custom_discount_fjgndfl28') {
// possible types are: 'fixed_cart', 'percent', 'fixed_product' or 'percent_product.
$discount_type = 'fixed_cart';
// how you calculate the ammount and where you get the data from is totally up to you.
$amount = $get_or_calculate_the_coupon_ammount;
if(!$discount_type || !$amount) return false;
$coupon = array(
'id' => 9999999999 . rand(2,9),
'amount' => $amount,
'individual_use' => false,
'product_ids' => array(),
'exclude_product_ids' => array(),
'usage_limit' => '',
'usage_limit_per_user' => '',
'limit_usage_to_x_items' => '',
'usage_count' => '',
'expiry_date' => '',
'apply_before_tax' => 'yes',
'free_shipping' => false,
'product_categories' => array(),
'exclude_product_categories' => array(),
'exclude_sale_items' => false,
'minimum_amount' => '',
'maximum_amount' => '',
'customer_email' => '',
'discount_type' => $discount_type,
);
return $coupon;
}
}
add_action('woocommerce_before_calculate_totals', 'applyFakeCoupons');
function applyFakeCoupons() {
global $woocommerce;
// $woocommerce->cart->remove_coupons(); remove existing coupons if needed.
$woocommerce->cart->applied_coupons[] = $this->coupon_code;
}
add_filter( 'woocommerce_cart_totals_coupon_label', 'cart_totals_coupon_label', 100, 2 );
function cart_totals_coupon_label($label, $coupon) {
if($coupon) {
$code = $coupon->get_code();
if($code == 'custom_discount_fjgndfl28') {
return 'Your custom coupon label';
}
}
return $label;
}
请注意:我从一个处理更多的类中复制了这些函数,它只是为了帮助你开始。
