Thinkphp无限级分类实现程序代码

public $listall = array();

$listmessage = $message->where('article_id = '.$list['artid'].'')->order('id DESC')->select(); //暂且你的表名字为message

foreach( $listmessage as $v){
if($v['pid'] == 0){
echo $v['username']."
";
$this->listall[] = $v;
$this->wuxian_f($v['id'] ,$nb );
}
}

//无限极分类测试
protected function wuxian_f( $fid ,$nb){
$message = M('message');
$hf = $message->where('pid = "'.$fid.'"')->select();
if($hf){
foreach($hf as $c){
$nb = $nb . "----";
echo  $nb.$c['username']."
";
$this->listall[] = $c;
$hc = $message->where('pid = "'.$c['id'].'"')->find();
if($hc){
$nb = $nb . "----";
echo $nb.$hc['username']."
";
$this->listall[] = $hc;
$this->wuxian_f( $hc['id'] ,$nb);
}
}
}
}
