自定义帖子类型和分类的WordPress重写规则

过去，由于对我遇到的问题进行了大量的Google搜索，因此我发现该位置过去是很好的信息来源。我的问题与WordPress使用的详细重写规则有关。

我已经建立了一个自定义后类型，称为项目，而且我已经注册了一个名为自定义分类项目。除了rewrite slug选项，所有其他方法都很有效，因为它们最终会发生冲突-很有可能是由于rewrite规则所致。

基本上，这就是我要实现的结构：

• example.com/work/%taxonomy%/%post_name%/ （用于帖子）
• example.com/work/%taxonomy%/ （列出属于特定分类术语的帖子）
• example.com/work/ （转到包含taxonomy.php的page-work.php，以列出与该分类法相关的所有帖子）

这是我到目前为止的代码，但是我需要编写WP_Rewrite规则的帮助，因为这有点让我感到困惑。

$labels = array(
    'name' => _x('Projects', 'post type general name'),
    'singular_name' => _x('Project', 'post type singular name'),
    'add_new' => _x('Add New', 'project item'),
    'add_new_item' => __('Add New Project'),
    'edit_item' => __('Edit Project'),
    'new_item' => __('New Project'),
    'view_item' => __('View Project'),
    'search_items' => __('Search Projects'),
    'not_found' =>  __('Nothing found'),
    'not_found_in_trash' => __('Nothing found in Trash'),
    'parent_item_colon' => ''
);

$args = array(
    'labels' => $labels,
    'public' => true,
    'publicly_queryable' => true,
    'hierarchical' => true,
    'rewrite' => array('slug'=>'work', 'with_front'=>false),
    'show_ui' => true,
    '_builtin' => false, // It's a custom post type, not built in!
    'capability_type' => 'post',
    'query_var' => "project", // This goes to the WP_Query schema
    'menu_position' => null,
    'supports' => array('title','editor','thumbnail', 'comments', 'author', 'excerpt')
);

register_post_type('project' , $args);

// Showcase Taxonomy
register_taxonomy('projects', array('project'), array(
    'public' => true,
    'hierarchical' => true,
    'label' => 'Project Categories', 
    'singular_label' => 'Project Category',
    'query_var' => true,
    'rewrite' => array('slug'=>'work', 'with_front'=>false, 'hierarchical'=>true)
    )
);

非常感谢您的帮助！:-)

希望这可以解决您的问题

function my_custom_post_type() {
$labels = array(
    'name' => _x('Projects', 'post type general name'),
    'singular_name' => _x('Project', 'post type singular name'),
    'add_new' => _x('Add New', 'project item'),
    'add_new_item' => __('Add New Project'),
    'edit_item' => __('Edit Project'),
    'new_item' => __('New Project'),
    'view_item' => __('View Project'),
    'search_items' => __('Search Projects'),
    'not_found' =>  __('Nothing found'),
    'not_found_in_trash' => __('Nothing found in Trash'),
    'parent_item_colon' => '',
    'menu_name' => 'Projects'

    'menu_position' => null,
    'supports' => array('title','editor','thumbnail', 'comments', 'author', 'excerpt')
);

register_post_type( 'work' , $args );

}
function my_custom_taxonomies() {

    $labels = array(
        'name' => __( 'Taxonomy', 'taxonomy general name' ),
        'singular_name' => __( 'Taxonomy', 'taxonomy singular name' ),
        'search_items' =>  __( 'Search Taxonomy' ),
        'all_items' => __( 'All Taxonomy' ),
        'parent_item' => __( 'Parent Taxonomy' ),
        'parent_item_colon' => __( 'Parent Taxonomy:' ),

        'new_item_name' => __( 'New Taxonomy Name' ),
        'menu_name' => __( 'Taxonomy' ),
    );  

    register_taxonomy( 'taxonomy', array('work'), array (
                    'labels' => $labels,
                    'hierarchical' =>false,

                    'show_in_nav_menus' => true,
                    'public' => true,
            ));
}

add_action('init', 'my_custom_post_type', 0);
add_action('init', 'my_custom_taxonomies', 10);

您需要创建的是archive-work.php（您的帖子类型存档）和taxonomy.php，它们将用于显示您的自定义分类存档。

我遇到了同样的问题，经过很多努力，最终还是得到了这个解决方案。
只需将其添加到您的代码中

global $wp_rewrite;
$wp_rewrite->flush_rules(); 

function my_custom_post_type() {
    $labels = array(
        'name' => _x('Projects', 'post type general name'),
        'singular_name' => _x('Project', 'post type singular name'),
        'add_new' => _x('Add New', 'project item'),
        'add_new_item' => __('Add New Project'),
        'edit_item' => __('Edit Project'),
        'new_item' => __('New Project'),
        'view_item' => __('View Project'),
        'search_items' => __('Search Projects'),
        'not_found' =>  __('Nothing found'),
        'not_found_in_trash' => __('Nothing found in Trash'),
        'parent_item_colon' => '',
        'menu_name' => 'Projects' 
    );

    $args = array(
        'labels' => $labels,
        'public' => true,
        'publicly_queryable' => true,
            'hierarchical' => false,
            'has_archive' => true,
        'rewrite' => array('slug'=>'work', 'with_front'=>false),
        'show_ui' => true,
        '_builtin' => false, // It's a custom post type, not built in!
        'capability_type' => 'post',
            'query_var' => true, // This goes to the WP_Query schema
        'menu_position' => null,
        'supports' => array('title','editor','thumbnail', 'comments', 'author', 'excerpt')
    );

    register_post_type( 'work' , $args );

    global $wp_rewrite;   
    $wp_rewrite->flush_rules();    // this should help 
}

更详细的解释在另一篇文章中，但这是您需要添加的基本部分：

1. 注册您的分类法和cpt。确保分类单元的重写段为“ basename”，而cpt的重写段为“ basename /％tax_name％”。

2. 像这样告诉wordpress如何处理“％tax_name％”：

   function filter_post_type_link($link, $post)
   {
   if ($post->post_type != 'custom_post_type_name')
       return $link;
   
   if ($cats = get_the_terms($post->ID, 'taxonomy_name'))
   {
       $link = str_replace('%taxonomy_name%',array_pop($cats)->term_id, link); // see custom function defined below
   }
   return $link;
   }
   add_filter('post_type_link', 'filter_post_type_link', 10, 2);
