public function NewsList(){
$this->assign('title','news');
$p = I('page',1);
$listRows = 6;
$News = M('news');
$info = $News->field('id,title,subtitle,publish_date,img,detail,typename')->where(array('type'=>'news','status'=>'1'))->order('flag desc,sort_no desc')->page($p,$listRows)->select();
if(!empty($info)){
foreach($info as $k=>$v){
$info[$k]['detail']=mb_substr($v['detail'],0,130,'utf-8');
}
}
$this->assign('news',$info);
$count = $News->where(array('type'=>'news','status'=>'1'))->count();
$Page = new Page($count,$listRows);
$show = $Page->show();
$this->assign('page',$show);
$this->display();
}

前端获取数据:



{$new.detail}......


thinkphp读取数据库数据:


<?php
//读取一行数据
$user=M("user");
$data=$user->where("status=1 AND name="thinkphp"")->find();
dump($data);
//读取数据集合
$User=M("user");
$list = $user->where('status=1')->order("create_time")->limit(10)->select();
//读取字段值
$user=M("user");
$nickname=$user->where("id=3")->getFild('nickname');
//如果传入多个字段
$user=M("user");
$list=$user->getFild('id,nickname');
//两个字段的情况下返回的是array(`id`=>`nickname`)的关联数组,以id的值为key,nickname字段值为value。
