php think make:validate index/User

namespace app\index\validate; use think\Validate; class User extends Validate { protected $rule = [ ‘name‘ => ‘require|max:25‘, ‘age‘ => ‘number|between:1,120‘, ‘email‘ => ‘email‘, ]; protected $message = [ ‘name.require‘ => ‘名称必须‘, ‘name.max‘ => ‘名称最多不能超过25个字符‘, ‘age.number‘ => ‘年龄必须是数字‘, ‘age.between‘ => ‘年龄只能在1-120之间‘, ‘email‘ => ‘邮箱格式错误‘, ]; }

事实上控制器类提供了一个validate方法可以更方便的进行验证，如下： 推荐使用 namespace app\index\controller; use think\Controller; class Index extends Controller { public function index() { $result = $this->validate( [ ‘name‘ => ‘thinkphp‘, ‘email‘ => ‘[email protected]‘, ], ‘app\index\validate\User‘); if (true !== $result) { // 验证失败 输出错误信息 dump($result); } } }

自定义验证规则 系统内置了一些常用的规则（参考后面的内置规则），如果不能满足需求，可以在验证器重添加额外的验证方法，例如： namespace app\index\validate; use think\Validate; class User extends Validate { protected $rule = [ ‘name‘ => ‘checkName:thinkphp‘, ‘email‘ => ‘email‘, ]; protected $message = [ ‘name‘ => ‘用户名必须‘, ‘email‘ => ‘邮箱格式错误‘, ]; // 自定义验证规则 protected function checkName($value,$rule,$data=[]) { return $rule == $value ? true : ‘名称错误‘; } } 验证方法可以传入的参数共有5个（后面三个根据情况选用），，依次为： 验证数据 $value 验证规则 $rule 这两个字段常用 全部数据（数组） 字段名 字段描述

$rule = [ ‘name‘ => ‘require|max:25‘, ‘age‘ => ‘number|between:1,120‘, ‘email‘ => ‘email‘, ]; $msg = [ ‘name.require‘ => ‘名称必须‘, ‘name.max‘ => ‘名称最多不能超过25个字符‘, ‘age.number‘ => ‘年龄必须是数字‘, ‘age.between‘ => ‘年龄只能在1-120之间‘, ‘email‘ => ‘邮箱格式错误‘, ]; $data = [ ‘name‘ => ‘thinkphp‘, ‘age‘ => 10, ‘email‘ => ‘[email protected]‘, ]; $validate = Validate::make($rule,$msg); $result = $validate->check($data); if(!$result) { dump($validate->getError()); }

Validate::extend(‘checkTitle‘,function ($value,$rule){ return strstr($value,$rule)? ‘字符中不能出现:‘.$rule : true; }); $rule = [‘title‘ => ‘require|min:2|checkTitle:张三‘, ‘content‘ => ‘require|min:10‘]; $msg = [‘title.require‘ => ‘标题必须‘, ‘content.require‘ => ‘内容必须‘, ‘title.min‘ => ‘标题长度最小为2个字符‘, ‘content.min‘ => ‘内容长度最小为10个字符‘, ]; $validate = Validate::make($rule, $msg); $ret = $validate->check($request->post());
