### thinkphp5提交form表单内容校验规则代码整理 ###

*   *  校验规则validate代码
     *  调用校验类
     *  提交form表单校验

## 校验规则validate代码 ##

我们在application目录中创建公用函数存放目录common，新建校验目录validate，创建校验提交的管理员登录信息校验规则php文件  
AdminUser.php

<?php
    namespace app\common\validate;
    use think\Validate;
    class AdminUser extends Validate
    { 
        //校验规则
        protected $rule = [
            'username' => 'require|max:10|min:4',
            'password' => 'require|max:12|min:6',
        ];
    }

## 调用校验类 ##

<?php
    namespace app\admin\controller;
    use think\Controller;
    class Admin extends Controller
    { 
        public function add()
        { 
            //判断是否为post提交
            if (request()->isPost()) { 
                //得到post提交的数据
                $data = (input('post.'));
                //实例化校验规则类库
                $validate = validate('AdminUser');
                //校验
                if (!$validate->check($data)) { 
                    $this->error($validate->getError());
                }
            } else { 
                //加载视图文件
                return $this->fetch();
            }
        }
    }
