composer require w7/engine-validate




try {
    $data = Validate::make([
        'user' => 'required|email',
        'pass' => 'required|lengthBetween:6,16',
    ], [
        'user.required'      => '请输入用户名',
        'user.email'         => '用户名格式错误',
        'pass.required'      => '请输入密码',
        'pass.lengthBetween' => '密码长度为6~16位',
} catch (ValidateException $e) {
    echo $e->getMessage();





class LoginValidate extends Validate
    protected $rule = [
        'user' => 'required|email',
        'pass' => 'required|digits_between:6,16',
    protected $message = [
        'user.required'       => '请输入用户名',
        'user.email'          => '用户名格式错误',
        'pass.required'       => '请输入密码',
        'pass.digits_between' => '密码长度为6~16位',


$data = [
    'user' => '123@qq.com',
    'pass' => ''
$validate = new LoginValidate();


$data = [
    'user' => '123@qq.com',
    'pass' => '123456'
$validate = new LoginValidate();
$data = $validate->check($data);



验证表单的输入为数组的字段也不难。你可以使用 「点」方法来验证数组中的属性。例如,如果传入的 HTTP 请求中包含search[keyword]字段, 可以如下验证:

protected $rule = [
    'search.order'   => 'numeric|between:1,2',
    'search.keyword' => 'chsAlphaNum',
    'search.recycle' => 'boolean',

你也可以验证数组中的每个元素。例如,要验证指定数组输入字段中的每一个 id 是唯一的,可以这么做:

protected $rule = [
    'search.*.id' => 'numeric|unique:account'


protected $message = [
    'search.order.numeric'       => '排序参数错误',
    'search.order.between'       => '排序参数错误',
    'search.keyword.chsAlphaNum' => '关键词只能包含中文,字母,数字',
    'search.recycle.boolean'     => '参数错误:recycle',




// 类中定义
protected $rule = [
    'user' => 'required'

// 使用方法定义
    'user' => 'required'



// 类中定义
protected $message = [
    'user.required' => '账号必须填写'

// 使用方法定义
    'user.required' => '账号必须填写'



// 类中定义
protected $scene = [
    'login' => ['user', 'pass']

// 使用方法定义
    'login' => ['user', 'pass']



protected $event = [


定义验证字段的名称,也可以通过setCustomAttributes方法来进行设置,此方法为叠加,如果参数为null则为清空全部字段名称, 错误消息中的:attribute会使用下面的值对应的替换

protected $customAttributes = [
    'user' => '账号',
    'pass' => '密码'



protected $default = [
    'name' => '张三'




protected $filter = [
    'name' => 'trim'




 protected $ruleMessage = [





  • 验证规则中存在filled, nullable, accepted, present,required, required_if, required_unless, required_with,required_with_all, required_without, required_without_all规则
  • 验证规则存在extendImplicit定义的规则
  • 验证规则存在extendImplicitRule定义的规则
  • 验证规则实现了Itwmw\Validation\Support\Interfaces\ImplicitRule标记接口
protected bool $filled = true;



protected $regex = [
    'number' => '/^\d+$/'



protected $group = [
    'username' => 'alpha_num|min:5|max:10'

protected $rule = [
    'username' => 'required|username'
