Example of unlimited reply comment function implemented by thinkPHP framework

In this paper, an example is given to describe the unlimited reply and comment function realized by thinkPHP framework. Share it for your reference, as follows:

If it is just a simple comment with a single reply, it is very simple to do so. But the question is how to achieve unlimited reply comments! So if it is only a single reply, it is impossible to build a lot of data tables. Then use TP framework to realize unlimited reply comments (GitHub source code download address: https://github.com/Jonybin/responsemessage). Pay attention to the use of database after downloading.

control controller section:

function CommentList($pid = 0, &$commentList = array(), $spac = 0) {
    static $i = 0;
    $spac = $spac + 1; // Initially 1 Level comments 
    $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; // Comment hierarchy 
      $commentList[$i]['author'] = $v['author'];
      $commentList[$i]['id'] = $v['id'];
      $commentList[$i]['pid'] = $v['pid']; // The father of this comment 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 section:

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