为了方便那些以后发现这一点,这里是@David 的方便代码,其中包含我的修改,以支持具有 WooCommerce 变体和 Gravity Forms Addons 变体的产品。
/**
* WooCommerce Gravity Forms Add-on: Add support for removing a field from the product description in the cart.
* This handy code came from: https://gist.github.com/spivurno/6951662 as a result of this
* discussion: https://gravitywiz.com/how-to-hide-gravity-forms-product-fields/
*
* It's used to remove the calulational fields in product forms from the cart.
