Wordpress 媒体设置界面

WordPress 3.5以上的版本,隐藏了后台的媒体(Media)设置页面 上传路径(upload_path)和文件 URL 地址(upload_url_path)的设定。

将下面的代码添加到主题的 functions.php 即可恢复设置界面:

if(get_option('upload_path')=='wp-content/uploads' || get_option('upload_path')==null) {
	update_option('upload_path',WP_CONTENT_DIR.'/uploads');
}

默认输出的 InnerXml 显示在一行,看起来非常痛苦,特别是复杂XML文档,输出格式化后的 InnerXml 可以方便快速的查看。

public string GetFormattedInnerXml(XmlDocument doc)
{
    StringBuilder builder = new StringBuilder();
    using (StringWriter sw = new StringWriter(builder))
    {
        using (XmlTextWriter xtw = new XmlTextWriter(sw))
        {
            xtw.Formatting = Formatting.Indented;
            xtw.Indentation = 1;
            xtw.IndentChar = '\t';
            doc.WriteTo(xtw);
        }
    }
    return builder.ToString();
}
