如何让wordpress自动添加特色图片？

Question

我正在尝试让 wordpress 在新帖子中自动添加特色图片。

条件：

• 帖子类别 ID 必须为 3
• 每个作者/用户都有自己的形象。
• 图像（已上传）具有以下名称格式： [名字作者]-[姓氏作者].jpg。

例如；当 Steve Jobs 提交帖子时，提交的帖子类别 id 应为 3，为该帖子设置的特色图片应为 'steve-jobs.jpg'。

最终工作代码：

function set_featured_image_blog_post() {
    global $post;
    $already_has_thumb = has_post_thumbnail( $post->ID );
    $post_category = get_the_category( $post->ID );
    if ( !$already_has_thumb && $post_category[0]->cat_ID  == 3 )  {
        if( $post->post_author == 3 ){
            set_post_thumbnail( $post->ID, 165 );
        }
        else if( $post->post_author == 4 ){
            set_post_thumbnail( $post->ID, 166 );
        }       
    }
}

add_action('the_post', 'set_featured_image_blog_post');
add_action('save_post', 'set_featured_image_blog_post');
add_action('draft_to_publish', 'set_featured_image_blog_post');
add_action('new_to_publish', 'set_featured_image_blog_post');
add_action('pending_to_publish', 'set_featured_image_blog_post');
add_action('future_to_publish', 'set_featured_image_blog_post');
