Wordpress 自定义帖子类型 - 相同的帖子名称，不同的帖子类型 [英] Wordpress Custom Post Type - Same Post Name, Different Post Type

问题描述

我有 4 种自定义帖子类型:

I have 4 Custom Post Types:

服务常见问题价格之前和之后

Services FAQs Prices Before and After

我希望能够在每种帖子类型中使用相同的帖子名称，例如:

I want to be able to have the same post names within each of these post types, example:

服务
皮肤 (example.com/Services/skin)
奶油(example.com/Services/cream)
正文(example.com/Services/body)

Services
Skin (example.com/Services/skin)
Cream (example.com/Services/cream)
Body (example.com/Services/body)

常见问题
皮肤 (example.com/FAQs/skin)
奶油(example.com/FAQs/cream)
正文(example.com/FAQs/body)

FAQs
Skin (example.com/FAQs/skin)
Cream (example.com/FAQs/cream)
Body (example.com/FAQs/body)

价格
皮肤 (example.com/Prices/skin)
奶油(example.com/Prices/cream)
正文(example.com/Prices/body)

Prices
Skin (example.com/Prices/skin)
Cream (example.com/Prices/cream)
Body (example.com/Prices/body)

之前和之后
皮肤 (example.com/before-and-after/skin)
奶油(example.com/before-and-after/cream)
正文(example.com/before-and-after/body)

Before and After
Skin (example.com/before-and-after/skin)
Cream (example.com/before-and-after/cream)
Body (example.com/before-and-after/body)

我该怎么做?现在，如果我创建一个与当前帖子同名的新帖子，它会在帖子 slug 的末尾添加一个-2"或-3":

How can I do this? Right now if I make a new post with the same name as a current one, it adds a "-2" or "-3" to the end of the posts slug:

糟糕:

example.com/services/body

example.com/services/body

example.com/faqs/body-2

example.com/faqs/body-2

example.com/prices/body-3

example.com/prices/body-3

example.com/before-and-after/body-4

example.com/before-and-after/body-4

请有人帮忙！！！！！！

我编写了一个函数，可以添加到您主题的functions.php 文件中，该文件包含 mboynes 在这张票中编写的补丁:http://core.trac.wordpress.org/ticket/18962#comment:14

I wrote a function that can be added to your theme's functions.php file that includes the patch written by mboynes in this ticket: http://core.trac.wordpress.org/ticket/18962#comment:14
