自定义固定链接结构:/%custom-post-type%/%custom-taxonomy%/%post-name%/ [英] Custom permalink structure: /%custom-post-type%/%custom-taxonomy%/%post-name%/

问题描述

我正在尝试创建一个自定义永久链接结构，以便我完成以下操作.

I'm trying to create a custom permalink structure that will allow me to accomplish the following.

1. 我有一个名为项目"的自定义帖子类型
2. 我有一个名为project-category"的自定义分类法，它被分配给 CPTprojects"

我希望我的永久链接结构如下所示:

I want my permalink structure to look like this:

项目/类别/项目名称

或

/%custom-post-type%/%custom-taxonomy%/%post-name%/

/%custom-post-type%/%custom-taxonomy%/%post-name%/

我已经能够成功地将/%category%/用于普通的、现成的 WP 帖子的永久链接，但不能用于 CPT.

I've been able to succesfully use /%category%/ in permalinks for normal, out-of-the-box WP posts, but not for CPTs.

创建这样的永久链接结构将如何影响 URL 或其他页面?是否可以定义自定义永久链接结构并将其限制为单个 CPT?

How would creating such a permalink structure affect the URLs or other pages? Is it possible de define a custom permalink structure and restrict it to a single CPT?

谢谢

推荐答案

你很幸运，我只是不得不为一个客户项目做这件事.我使用 WordPress Stackexchange 上的这个答案 作为指南:

Lucky for you, I just had to do this for a client project. I used this answer on the WordPress Stackexchange as a guide:

/**
 * Tell WordPress how to interpret our project URL structure
 *
 * @param array $rules Existing rewrite rules
 * @return array
 */
function so23698827_add_rewrite_rules( $rules ) {
  $new = array();
  $new['projects/([^/]+)/(.+)/?$'] = 'index.php?cpt_project=$matches[2]';
  $new['projects/(.+)/?$'] = 'index.php?cpt_project_category=$matches[1]';

  return array_merge( $new, $rules ); // Ensure our rules come first
}
add_filter( 'rewrite_rules_array', 'so23698827_add_rewrite_rules' );

/**
 * Handle the '%project_category%' URL placeholder
 *
 * @param str $link The link to the post
 * @param WP_Post object $post The post object
 * @return str
 */
function so23698827_filter_post_type_link( $link, $post ) {
  if ( $post->post_type == 'cpt_project' ) {
    if ( $cats = get_the_terms( $post->ID, 'cpt_project_category' ) ) {
      $link = str_replace( '%project_category%', current( $cats )->slug, $link );
    }
  }
  return $link;
}
add_filter( 'post_type_link', 'so23698827_filter_post_type_link', 10, 2 );

在注册自定义帖子类型和分类时，请务必使用以下设置:

When registering the custom post type and taxonomy, be sure to use the following settings:

// Used for registering cpt_project custom post type
$post_type_args = array(
  'rewrite' => array(
    'slug' => 'projects/%project_category%',
    'with_front' => true
  )
);

// Some of the args being passed to register_taxonomy() for 'cpt_project_category'
$taxonomy_args = array(
  'rewrite' => array(
    'slug' => 'projects',
    'with_front' => true
  )
);

当然，完成后一定要刷新重写规则.祝你好运！

Of course, be sure to flush rewrite rules when you're done. Good luck!
