Answer 1

我是这样写的，麻烦你帮我看看，应该怎么修改呢？你指的是修改后台还是前台呀？
前台：<?php
 /*
  +-----------------------------------------------------------
  *这是日记的类，它显示的是日记相关的内容
  +-----------------------------------------------------------
  */
 class DiaryAction extends Action{
 
  public function index(){
  $this->assign('title','日记');
  $diary = M('diary');
  $list = $diary->select();
  $this->assign('list',$list);
  $this->display();   
  }
 }
 ?>前台：<volist id='vo' name='list'>
  <li>
  <div class="post-title"><span class="diary_title">{$vo['content']}</span></div>
  <div class="post-details">发表于 <a href="###">{$vo['mtime']|date='Y年m月d日 H:i:s',###}</a>&nbsp;|&nbsp;
                             <a href="###">赞({$vo['zan']})</a>&nbsp;|&nbsp;
                             <a href="###">阅读({$vo['read']})</a>&nbsp;|&nbsp;
                             <a href="" onclick="rediary_open({$vo['id']});return false;">评论(22)</a>
                             <a href="" id="s{$vo['id']}" style="display:none;" onclick="rediary_close({$vo['id']});return false;">&nbsp;|&nbsp;收起评论</a>
                             </div>
                             <div class="post-details" style="display:none;" id="d{$vo['id']}">
                             <span class="rediary_name">王文敏</span>：你说得很好，很对。&nbsp;&nbsp;<a href="###">1小时前</a><br />
                             <span class="rediary_name">沈洪松</span>：哈哈，这个笑话真好笑，你成了鸭了~&nbsp;&nbsp;<a href="###">3小时前</a><br />
                             <span class="rediary_name">邵书军</span>：这个笑话很久以前就见过啦，你OUT了，要与时俱进啊！这个笑话很久以前就见过啦，你OUT了，要与时俱进啊！这个笑话很久以前就见过啦，你OUT了，要与时俱进啊！&nbsp;&nbsp;<a href="###">{$vo['mtime']|mdate=###}</a><br />
                             <input type="text" size="15" name="comment" value="名字" style="vertical-align:middle;"/>&nbsp;
                             <input type="text" size="50" name="comment" value="我也说一句" style="vertical-align:middle;"/>&nbsp;
                             <input type="submit" value="发表" style="height:29px; vertical-align:middle;border:0px none;"/>
                             </div>
  </li>
  </volist>
