dede文章页面如何显示作者的头像默认只能显示作者用户名
<p><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>dede在文章页面显示作者只是显示其用户名，但是假如我想把dede改造成较为社交化的网站，我觉得是有必要显示作者的<u>头像</u>的，但是官方并没有相应的模版标签。 </span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>在网上看到解决这个问题的办法基本上是直接在模版页面调用runphp的程序段，的确这种办法是可行的。 </span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>但是我不倾向于这么做，因为很多时候我们都需要差异化的功能，每次都这样夹杂着php代码看起来很乱。 </span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>我是直接在php文件里面修改的，让文章模版可以调用几个新的标签。 </span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>找到/include/arc.archives.class.php文件 </span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>搜索“$this->addTableRow = $this->dsql->GetOne($query);”，跳转到大概154行，在else{ $this->Fields['templet'] = $this->Fields['redirecturl'] = '';}下面添加如下代码： </span></p>
