WordPress的：當我添加一篇文章，這個詞將自動創建？

Question

我有一個自定義帖子類型稱爲「產品」與自定義分類「作者」。現在我有另一種稱爲「作者」的自定義帖子類型。

我想這樣：當我在我的文章類型「作者」中發佈新帖子時，將在我的分類「作者」中自動創建一個具有相同標題的新詞語。可能嗎？

感謝您的幫助。

請試試這可能會對你有幫助。

function update_custom_terms($post_id) { 

    // only update terms if it's a authors post 
    if ('authors' != get_post_type($post_id)) { 
    return; 
    } 

    // don't create or update terms for system generated posts 
    if (get_post_status($post_id) == 'auto-draft') { 
    return; 
    } 

    /* 
    * Grab the post title and slug to use as the new 
    * or updated term name and slug 
    */ 
    $term_title = get_the_title($post_id); 
    $term_slug = get_post($post_id)->post_name; 

    /* 
    * Check if a corresponding term already exists by comparing 
    * the post ID to all existing term descriptions. 
    */ 
    $existing_terms = get_terms('author', array(
    'hide_empty' => false 
    ) 
); 

    foreach($existing_terms as $term) { 
    if ($term->description == $post_id) { 
     //term already exists, so update it and we're done 
     wp_update_term($term->term_id, 'author', array(
     'name' => $term_title, 
     'slug' => $term_slug 
     ) 
    ); 
     return; 
    } 
    } 

    /* 
    * If we didn't find a match above, this is a new post, 
    * so create a new term. 
    */ 
    wp_insert_term($term_title, 'author', array(
    'slug' => $term_slug, 
    'description' => $post_id 
    ) 
); 
} 

//run the update function whenever a post is created or edited 
add_action('save_post', 'update_custom_terms');
