我正在创建一个自定义的帖子表单，该表单将获取外部图像并将其上载到媒体库，然后将其附加到该帖子。这应该可以通过使用media\\u sideload\\u image实现，但我得到的是一个空白页面，而不是正常工作，也没有错误。我的代码：

// Add the content of the form to $post as an array
        $new_post = array(
            \'post_title\'    => $title,
            \'post_content\'  => $description,
            \'tags_input\'    => $tags,
            \'post_type\'     => \'link_submit\',
            \'post_status\'   => \'publish\'
        );
        //save the new post and return its ID
        if ($stop == false){
            $pid = wp_insert_post($new_post);
            update_post_meta($pid,\'Link\',$link,true);
            update_post_meta($pid,\'Type\',$type,true);
                    // attach image
            set_time_limit(300);
            $upload = media_sideload_image($link, $pid, "test");
            if ( is_wp_error( $upload ) ){
            die( \'Nope\' );
            }

            $link = get_permalink( $pid );
            wp_redirect( $link."?posted" );
            die();
        }   

谢谢，丹尼斯

编辑：新代码：

if (is_page(\'Upp\')){
    require_once(ABSPATH . \'wp-admin/includes/file.php\');
    require_once(ABSPATH . \'wp-admin/includes/media.php\');
    set_time_limit(300);
    $upload = media_sideload_image("http://29.media.tumblr.com/tumblr_lmp1tbiYwh1qzlfumo1_500.jpg", "202", "my description");
    die ( $upload );
}
