自动验证是thinkphp模型层提供的一种数据验证方法,可以在使用create创建数据对象的时候自动进行数据验证。分为静态验证和动态验证。
一、静态验证
(1)在home/controller/路径下新建index控制器。indexcontroller
indexcontroller.class.php页面
注意:静态定义方式因为必须定义模型类,所以只能用d函数实例化模型
create方法是对表单提交的post数据进行自动验证

<?php namespace home\controller; use think\controller; class indexcontroller extends controller { public function yanzheng(){ $u = d( "users" ); //造一个子类对象 if ( empty ( $_post )){ $this ->show(); } else { if ( $u ->create()){ //验证 echo "验证通过" ; } else { echo $u ->geterror(); //获取错误信息 } } } } |
(2)在view/index文件夹下做yanzheng.html页面

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd" > <html xmlns= "http://www.w3.org/1999/xhtml" > <head> <meta http-equiv= "content-type" content= "text/html; charset=utf-8" /> <title>无标题文档</title> <script src= "__root__/public/js/jquery-3.2.0.min.js" ></script> </head> <body> <h1>验证界面</h1> <form action= "__action__" method= "post" > <div>用户名:<input type= "text" name= "uid" /></div> <div>密码:<input type= "password" name= "pwd1" /></div> <div>确认密码:<input type= "password" name= "pwd2" /></div> <div>年龄:<input type= "text" name= "age" /></div> <div>邮箱:<input type= "text" name= "email" /></div> <div><input type= "submit" value= "验证" /></div> </form> </body> </html> |
效果图:
(3)在model层写静态验证的验证:(路径如图)
usersmodel.class.php

<?php namespace home\model; use think\model; class usersmodel extends model{ //添加验证条件 protected $_validate = array ( array ( "uid" , "require" , "用户名不能为空!" ), //默认情况下用正则进行验证 array ( "pwd1" , "require" , "密码不能为空!" ), array ( "pwd2" , "require" , "密码不能为空!" ), array ( "pwd2" , "pwd1" , "两次输入的密码不一致" ,0, "confirm" ), // 验证确认密码是否和密码一致 array ( "age" , "18,50" , "年龄不在范围内" ,0, "between" ), array ( "email" , "email" , "邮箱格式不正确" ), ); } |
依次验证效果图:
当全部为空时,点击验证
会跳转
输入用户名,其他不输入时,会跳转
两次密码输入不一致时,会提示;年龄不在范围内会提示;邮箱格式不正确时会提示;
输入正确格式内容后
二、动态验证
(1) indexcontroller.class.php页面

<?php namespace home\controller; use think\controller; class indexcontroller extends controller { public function yz(){ $u = m( "users" ); //造一个父类对象 if ( empty ( $_post )){ $this ->show(); } else { $rules = array ( array ( "uid" , "require" , "用户名不能为空!" ), ); if ( $u ->validate( $rules )->create()){ //验证 $this ->ajaxreturn( "ok" , "eval" ); } else { $this ->ajaxreturn( "no" , "eval" ); } } } } |

看一下效果:
当文本框失去焦点时:
当文本框有内容时,再失去焦点:
