ThinkPHP框架
index的
class IndexAction extends Action{
  public function index() { 
  $Demo = new Model('thinkphp'); // 实例化模型类 
  print_r($Demo);
  $list = $Demo->select(); // 查诟数据 
  $this->assign('list',$list); // 模板发量赋值 
  $this->display(); // 输出模板 
  }

?>

 
编号:{$vo.id}
 
标题: {$vo.text}
 
内容: {$vo.nr}


 
 

为啥不显示数据呢

------解决方案--------------------
这个你自己配debug调试下吧,笨点就在几个位置print出来看看是哪里出了问题
------解决方案--------------------
Runtime/log文件夹下有日志,你看看里面的sql语句神马的,看看哪错了,还不知道就把日志贴出来看看。
------解决方案--------------------
最简单的方法是
$list = M('Thinkphp')->select();

如果想要判断sql是否正确
直接打印 echo $dao->getLastSql();
------解决方案--------------------
你要先定位错误, 看哪个变量没有需要的值,编程基本功啊
------解决方案--------------------
$vo['id']
$vo['text']
试试、、
以前我好像也试过类似的错误,忘记了……
