我希望你回答
我使用钩子在购物车中的产品名称旁边显示变量

add_filter( 'woocommerce_product_variation_title_include_attributes', '__return_true' );

字符串
但如果一个产品有2个以上的变量，它将只显示前2个变量
true => product：变量1和变量2和变量3
false => product：变量1和变量2
路径：/wp-content/plugins/woologce/includes/data-stores/class-wc-product-variation-data-store-cpt.php

我注意到一件事：enter image description here
如果添加gender-one -> Blue -> Short到购物车，不显示Short产品标题，我必须创建2个变量来显示Short
性别一->蓝色->短
性别一->蓝色->高
