自定义分类返回 404，仅最后创建分类 200

Question

我有自定义帖子类型和此自定义帖子类型的 3 个自定义分类。我重写了分类学的 slug。但是所有分类归档都返回 404 错误，但最后一个分类归档返回 200。如果我创建新分类，最后分类也返回 404 错误，新分类有代码 200。如何解决？

我的代码：

add_action('init', 'main_avto_post_type');


function main_avto_post_type(){

    register_post_type('main_avto', array(
        'labels'             => array(
            'name'               => 'Schools', // Основное название типа записи
            'singular_name'      => 'School', // отдельное название записи типа Book
            'add_new'            => 'Add new',
            'parent_item_colon'  => '',
            'menu_name'          => 'Schools'

        ),
        'public'             => true,
        'publicly_queryable' => true,
        'show_ui'            => true,
        'show_in_menu'       => true,
        'query_var'          => true,
        'rewrite' => array( 'slug' => '/%main-city%', 'with_front' => false ),
        'has_archive' => 'avtoschools',
        'capability_type'    => 'post',
        'hierarchical'       => false,
        'menu_position'      => null,
        'supports'           => array('title','editor','author','thumbnail','excerpt','comments')
    ) );
}



add_action( 'init', 'create_main_avto_taxonomies' );

function create_main_avto_taxonomies(){


    register_taxonomy('main-city', array('main_avto'), array(

        'rewrite' => array( 'slug' => '/', 'with_front' => false ),
  
    ));

    register_taxonomy('main_subway', array('main_avto'), array(
        'hierarchical'  => true,
        'labels'        => array(
              'name'              => _x( 'Subway', 'taxonomy general name' ),

} 

Answer 1

当您使用任何东西时，添加自定义帖子类型或自定义分类...等。您应该始终使用flush_rewrite_rules() 重置重写规则。

删除重写规则，然后重新创建重写规则。此功能在与自定义帖子类型一起使用时很有用，因为它允许自动刷新 WordPress 重写规则（对于新的自定义帖子类型通常需要手动完成）。

• 来源@https://developer.wordpress.org/reference/functions/flush_rewrite_rules/

将以下内容添加到您的 function.php 文件的顶部。它应该可以解决您的404.php 错误问题。

<?php /**
* flush_rewrite_rules( bool $hard = true )
* Remove rewrite rules and then recreate rewrite rules.
* $hard (bool) (Optional) Whether to update .htaccess (hard flush) or just update rewrite_rules option (soft flush). Default is true (hard).
* Must be removed before pushing to live.

*/
flush_rewrite_rules(); ?>

在类似的问题上，将register_taxonomy() 移动到register_post_type() 之前作为suggested here 帮助了我。
