如何编写插件/固定链接：定制贴子类型->定制分类和定制贴子类型->定制分类(一个CPT和多个分类)？

时间：2020-03-04 作者：Sioban

这是我的第一篇帖子，所以我可能会错过一些信息，抱歉：鞠躬。

我的问题和Paul T几乎一样(Permalinks: custom post type -> custom taxonomy -> post), 即：

我有一个自定义的post类型，名为sioban\\u cpt，它有一个自定义的分类法sioban\\u taxo。

sioban\\U cpt可以more than one sioban\\u taxo。

我希望我的URL以这种方式路由：

www.mysite.com/sioban_cpt/  =>  archive-sioban-cpt.php
www.mysite.com/sioban_cpt/%sioban_taxo%/ => taxonomy-sioban_taxo.php
**www.mysite.com/sioban_cpt/%postname%/ => single-sioban_cpt.php**
因此：

www.mysite.com/sioban_cpt/ => shows all posts with sioban_cpt post-type (this works)
www.mysite.com/sioban_cpt/foo/ => shows all posts with the foo taxonomy(this works)
www.mysite.com/sioban_cpt/bar => shows the indivual post under the sioban_cpt post-type (this doesn\'t work, it display the error template, although www.mysite.com/sioban_cpt/bar is the shown permalink in the WP admin post edition page)
作为PaulT，我尽量避免使用插件。

我不知道解决方案是否可行，因为我希望分类法和CPT的帖子都是CPT的后代，相反，我不希望CPT的帖子是taxo的子类。

这是我的函数代码。php：

/**
 * create new custom taxonomy (has to be called before CPT declaration)
 *
 * @return void
 */
function si0b_ct_year()
{
    /* Property Type */
    $labels = array(

将参数传递给自定义帖子类型Single，同时保持URL干净

我正在将get参数传递给干净url中的单个自定义帖子类型。因此，例如，将有定制的职位类型“服务”，其中将有单个职位“园艺”。/services/gardening/leeds 这将转换为以下内容，以便可以在模板上访问变量：/services/gardening?location=leeds 但在浏览器中仍显示以下内容：/services/gardening/leeds 我只是想知道在使用自定义帖子类型之前是否有人这样做过？谢谢
