The example describes the infinite reply comment function implemented by the thinkPHP framework. Share it with everyone for your reference, the details are as follows:

If it is just a simple single reply comment, the operation is very simple. But the problem is how to achieve unlimited reply comments! So if there is only a single reply, many data tables need to be built, which is simply impossible to achieve. Then use the TP framework to achieve unlimited reply to comments, and pay attention to the use of the database.

control controller part:

function CommentList($pid = 0, &$commentList = array(), $spac = 0) {
    static $i = 0;
    $spac = $spac + 1; //初始为1级评论
    $List = M('comment')->
        field('id,add_time,author,content,pid')->
        where(array('pid' => $pid))->order("id DESC")->select();
    foreach ($List as $k => $v) {
      $commentList[$i]['level'] = $spac; //评论层级
      $commentList[$i]['author'] = $v['author'];
      $commentList[$i]['id'] = $v['id'];
      $commentList[$i]['pid'] = $v['pid']; //此条评论的父id
      $commentList[$i]['content'] = $v['content'];
      $commentList[$i]['time'] = $v['add_time'];
      // $commentList[$i]['pauthor']=$pautor;
      $i++;
      $this->CommentList($v['id'], $commentList, $spac);
    }
    return $commentList;
}

view view part:

<volist name="commentList" id="vo">
 <eq name="vo.pid" value="0"><hr class="solidline"/><else/><hr class="dottedline"/></eq>
 <p class="commentList " style="padding-left:{$vo[&#39;level&#39;]-1}cm">
   <p><span class="user">
   <if condition="($vo.pauthor eq NULL)">{$vo.author}
  <else /> {$vo.author}<span class="black" style="color: #000101">回复</span>{$vo.pauthor}
   </if>
 </span><a class="hf" id="{$vo.id}" style="float: right">回复</a><span class="hftime">{$vo.time|date="Y-m-d",###}</span></p>
   <p class="content">{$vo.content|reFace}</p>
 </p>
