 //调方法显示页面：如果为空显示

 

<?php
namespace Home\Model;
use Think\Model;
class ZhucCeModel extends Model
{
    protected $tablePrefix="";//表示表名没有加前缀
    protected $trueTableName="zhuce";//表示真实表名
    
     protected $_validate = array(
    array("uid","require","用户名不能为空"),//验证用户名不能为空
    array('pwd','pw1','两次输入的密码不一致',0,'confirm'),//验证两次输入的密码是否相同
    array("youxiang","email","邮箱格式不正确"),//email是已经封装好的通过（email）
    array("shengfenzheng",'/^(\d{15}$|^\d{18}$|^\d{17}(\d|X|x))$/','身份证号不正确',0,'regex'),//通过正则（regex）来验证
    array('age','18,50','年龄不在范围内',0,'between'),//验证年龄
    );
    
    
        
}
