檢查我們是否在新媒體上傳或媒體 - >添加新/ WordPress

Question

我工作的一個新的插件，可以在上傳到自定義文件夾後立即上傳圖片/文件。我有一個新的媒體上傳器（來自WP 3.5）的問題。我有移動上傳文件並生成附件元數據的功能。我通過add_action(add_attachment, '_the_function')調用這個函數。問題是，爲完成此操作，經典媒體庫需要在該功能的末尾打印附件ID：echo $post_ID，新媒體上傳器需要返回json數據return wp_send_json_success($attachment)。

如何檢查是否通過新媒體上傳器或媒體 - >添加新媒體上傳媒體。

add_action('add_attachment', array($this, 'up_move_media_after_add_attachment')); 

function up_move_media_after_add_attachment($post_ID) { 

    //... foregoing code (moving to custom folder) ... 

    # generates metadata for an image attachment and creates a thumbnail and other intermediate sizes of the image attachment 
    $metadata = wp_generate_attachment_metadata($post_ID, get_attached_file($post_ID)); 
    wp_update_attachment_metadata ($post_ID, $metadata); 

    if (___???????___) { 
     # upload from post via new media uploader, since 3.5 
     $attachment = wp_prepare_attachment_for_js($post_ID); 
     return wp_send_json_success($attachment); 

    } else { 
     # upload from media library 
     echo $post_ID; 

     # don't forget 
     exit; 

    } 

}

好吧，我發現以下解決方案：

if (basename($_SERVER['HTTP_REFERER']) == 'media-new.php'): 
    # upload from media library 
    echo $post_ID; 
    # don't forget 
    exit; 
else : 
    # upload from post via new media uploader, since 3.5 
    $attachment = wp_prepare_attachment_for_js($post_ID); 
    return wp_send_json_success($attachment); 
endif;
