laravel 自定义验证规则

1.扩展

public function modifyPwd()
{
    $this->checkPwd();
    return [
        'oldPwd' => 'required|check_pwd',
        'password' => 'required|between:6,16|confirmed',
        'password_confirmation' => 'required',
    ];
}

public function messages()
{
    return [
       
        'oldPwd.check_pwd'=>'原始密码不正确'
    ];
}

public function checkPwd()
{
    Validator::extend('check_pwd', function ($attribute, $value, $parameters, $validator) {
        $pwd = Auth::user()->password;
        return bcrypt($value) == $pwd;
    });
}
