WordPress插件WooCommerce支持Custom Fields。
可以在“屏幕选项”下切换自定义字段:
但是,这些自定义字段不会被product variations隔离。只有一组自定义字段适用于WooCommerce界面中的所有产品变体,这是不合适的,因为不同的产品变体可能具有不同的产品MPN,例如,这是我为自己设置的自定义字段之一。
我找到的closest off-site solution没有链接到自定义字段。下面显示的代码显示了如何在“产品变体”界面中设置输入字段。如何修改以下解决方案以将“产品变体”界面链接到自定义字段?
这个问题不同于与高级自定义字段有关的问题,因为我没有使用该插件。此外,至少one other similar question on Stack Overflow,但我不熟悉PHP,我不理解它,也不知道它是否相关 - 但我会指出OP和我没有接受解决方案不想在那里筑巢。
