是不是不能在 spModel子类 里面用 spClass() 其他的 spModel 类？我调用后，说findAll等函数不存在没声明.
class user_group extends spModel {
var $pk = "id"; // 每个留言唯一的标志，可以称为主键
var $table = "user_group"; // 数据表的名称
/**
* 根据ID删除分组信息
*
* @param int $id
*/
function deleteGroupById($id){
//获得组信息
$group = $this->getGroupMsgById($id);
if(!$group) Tips('抱歉，此用户组不存在！',0);
//查询这个组下面有多少人
$userNum = spClass('user');
$condistions = array('group'=>$id);
$num = $userNum -> findCount($condistions);//---------------------报错，说这个方法不存在
if($num >0 ) Tips('警告，此组下还有['.$num.']位用户，不能删除',0);
return $this -> deleteByPk ($id);
}
}
?>
看看报错：

类的调用是不区分在那里的，只要定义能载入。
楼主的问题，我看应该是user这个类，没有extends spModel吧？

回复 2 jake 定义了，而且我还dump()出了对象。

#4 jake
$userNum = spClass('user');
dump($userNum);
如果能dump出对象，那么有没有看到该对象的方法函数呢?

是控制器有个user类，这里建议一下model类都给个前缀就好。
