从文章中How to use WordPress 3.5 Media Uploader in Theme Options （由codestag.com提供），如中所示Using the WordPress 3.5 Media Uploader within plugins （由mikejolley.com提供）<迈克·乔利的文章有一些很好的技巧

Important note: 如果要使用上载程序的页面doesn\'t already have 所有媒体JS API，然后wp_enqueue_media() 必须打电话。

因此，假设我们在自定义元框中有这样一个按钮：

<div class="uploader">
      <input type="text" name="settings[_wpse_82857]" id="_wpse_82857" />
      <input class="button" name="_wpse_82857_button" id="_wpse_82857_button" value="Upload" />
</div> 

jQuery(document).ready(function($)
{
    var _custom_media = true,
        _orig_send_attachment = wp.media.editor.send.attachment;

    // ADJUST THIS to match the correct button
    $(\'.uploader .button\').click(function(e) 
    {
        var send_attachment_bkp = wp.media.editor.send.attachment;
        var button = $(this);
        var id = button.attr(\'id\').replace(\'_button\', \'\');
        _custom_media = true;
        wp.media.editor.send.attachment = function(props, attachment)
        {
            if ( _custom_media ) 
            {
                $("#"+id).val(attachment.url);
            } else {
                return _orig_send_attachment.apply( this, [props, attachment] );
            };
        }

        wp.media.editor.open(button);
        return false;
    });

    $(\'.add_media\').on(\'click\', function()
    {
        _custom_media = false;
    });
});
