验证器操作,个人理解
有助于用户提交的数据的二次验证
Validate实例
<?php /** * 验证 */ namespace app\index\model; use think\Validate as Zhang; class Validate extends Zhang { // 验证规则 protected $rule =[ 'name' =>'require|length:2,20', 'sex' =>'in:0,1', 'age' =>'require|between:18,29', 'money' =>'require|gt:2500', ]; //错误信息 protected $message =[ 'name.require' =>'员工姓名不能为空', 'name.leength' =>'姓名长度不够', 'sex.in' =>'只能输入男或者女', 'age.require' =>'年龄不能为空', 'age.leength' =>'注册年龄不满足', 'name.require' =>'员工姓名不能为空', 'name.leength' =>'姓名长度不够', 'money.require' =>'员工工资不能为空', 'money.gt' =>'工资必须大于2500']; }
