public function jigui(){
$mode=M('xb6f');
$jgmode=M('jigui');
$jgbh=$jgmode->select();
foreach ($jgbh as $key => $value) {
$jgbh[$key]['list']=$mode->where ("jgbh = '".$jgbh[$key]['jgbh']."'")->order('jgbh')->select();
}
$this->assign("list",$jgbh);
$this->display();
}然后模板显示方式<volist name="list" id="data">
<p>{$data.jgbh}</p>
<volist name="data['list']" id="ldata">
<p>{$ldata.IP}</p>
</volist>
</volist>请问我如何判断{$ldata.IP}这个值为空的时候输出无IP？ 最佳答案
