如何设置永久链接以在wordpress中使用父帖子获取所有儿童自定义帖子？

Question

我为自定义帖子类型创建父子关系.

通用:www.example.com/parent/parent_post

示例:www.example.com/projects/project-one

在上面的URL中,父级是自定义帖子类型,父级帖子是其单个帖子.我可以将父母的所有帖子和单个帖子分别显示为archive-parent.php和single-parent.php.

正如我之前提到的,我创建了父子关系,并将子帖子存储为'post_parent'作为父ID.

通用:www.example.com/child/parent_post/child_post

样本:www.example.com/project_article/project-one/first-article

对于特定的子帖子,URL将如上所述.

下面的代码是为了获得特定的子邮件.它工作正常.

function my_add_rewrite_rules() {
    add_rewrite_tag('%child%', '([^/]+)', 'child=');
    add_permastruct('child', 'child/%parent%/%child%', false);
    add_rewrite_rule('^child/([^/]+)/([^/]+)/?','index.php?child=$matches[2]','top');
}
add_action( 'init', 'my_add_rewrite_rules' );

function my_permalinks($permalink, $post, $leavename) {
    $post_id = $post->ID;
    if($post->post_type != 'child' || empty($permalink) || in_array($post->post_status, array('draft', 'pending', 'auto-draft')))
        return $permalink;
    $parent = $post->post_parent;
    $parent_post = get_post( $parent );
    $permalink = str_replace('%parent%', $parent_post->post_name, $permalink);
    return $permalink;
}
add_filter('post_type_link', 'my_permalinks', 10, 3);

通用:www.example.com/child/parent_post

示例:www.example.com/project_article/project-one

现在我想要所有带有父帖的子帖,如上面的URL.

我是新手,请按指南.

Answer 1

假设parent作为父自定义帖子类型，child作为子自定义帖子类型，并希望您需要子帖子 URL，例如http://www.example.com/parent/parent-post/child/child-post而不是http://www.example.com/child/parent-post/child-post.

将您的功能更改my_add_rewrite_rules()为以下内容。

function my_add_rewrite_rules() {
    add_rewrite_tag('%child%', '([^/]+)', 'child=');
    add_permastruct('child', '/parent/%parent%/child/%child%', false);
    add_rewrite_rule('^parent/([^/]+)/child/([^/]+)/?','index.php?child=$matches[2]','top');
}
add_action( 'init', 'my_add_rewrite_rules' );

更新后，不要忘记通过“设置 > 永久链接”刷新永久链接。
