自定义 Post 类型单页显示 404 错误

Question

我正在使用自定义 Post 类型永久链接通过 Toro_Unit 用于自定义 url 的插件。

这是我的自定义 post 类型

<?php

/**
 * Post Type: our-products.
 */
function cptui_register_my_cpts_our_products() {



    $labels = array(
        "name" => __("Our Products", "twentynineteen"),

        'rewrite' => array('slug' => 'tag'),
    ));
}

add_action('init', 'wpdocs_register_private_taxonomy1', 0);


flush_rewrite_rules( false );

我想制作自定义分类的 url

site_url/our-products/custom-taxonomy-name

单页

site_url/our-products/custom-taxomony-name/single-page-url

所以设置的时候

Url 工作正常。但它显示 404 错误。

试过：根本不起作用

设置刷新的永久链接-->永久链接-->自定义结构-->保存
flush_rewrite_rules( false ) 在 functions.php 和创建时自定义 post 类型
已提供解决方案here
也尝试了this解决方案
.htaccess 文件：检查没有问题。
在经历了所有的挫折之后，安装了一个新的设置，创建了一个自定义 post 类型并将永久链接设置为 /%category%/%postname%/ ，而不是为自定义 post 类型工作。

仅供参考，我使用的是wordpress 5.3.1，与主题或插件没有冲突。已测试。

Answer 1

注册自定义 post 类型时将此添加到您的自定义 post 类型

"taxonomies" => [ "category", "product-category" ],

当时有效

Answer 2

问题出在这一行：

register_taxonomy('tag', 'our-products', array(

当您使用“tag”关键字时，事情会发生冲突。

您可以重命名您的自定义分类法，但您将丢失已添加的术语。

您可以使用自定义 query_var 参数来解决这个问题，不要将其设置为 true。该参数还接受一个字符串：

'query_var' => 'a'
