自定义永久链接结构:/%custom-post-type%/%custom-taxonomy%/%post-name%/

Question

我正在尝试创建一个自定义永久链接结构,这将允许我完成以下操作.

1. 我有一个名为"项目"的自定义帖子类型
2. 我有一个名为"项目类别"的自定义分类,分配给CPT"项目"

我希望我的永久链接结构看起来像这样:

项目/分类/项目名称

要么

/%自定义后类型%/%自定义分类%/%-名哨%/

我已经成功地在永久链接中使用/%category%/来获得正常的,开箱即用的WP帖子,但不能用于CPT.

如何创建这样的永久链接结构会影响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？

谢谢

幸运的是,我只需为客户项目做这件事.我在WordPress Stackexchange上使用这个答案作为指南:

/**
 * 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 );

注册自定义帖子类型和分类时,请务必使用以下设置:

// 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,确保在完成后刷新重写规则.祝好运!
