tp5的validate的使用

一：利用validate函数例如  $validate = validate（'验证器名称，首字母大写'）；还可以有验证场景

   if(!validate->check('post.')){

    $this->error($validate->getError());

}else{

}

二

         $data            = $this->request->only(['username', 'password', 'verify']); 
            $validate_result = $this->validate($data, 'Login');

            if ($validate_result !== true) {
                $this->error($validate_result);
            }

验证器的写法

 1.

 protected $rule = [
        'username' => 'require',
        'password' => 'require',
        'verify'   => 'require|captcha'
    ];

    protected $message = [
        'username.require' => '请输入用户名',
        'password.require' => '请输入密码',
        'verify.require'   => '请输入验证码',
        'verify.captcha'   => '验证码不正确'
    ];

2.连写

 protected  $rule = [
        ['username', 'require|max:1000', '用户名必须传递|分类名不能超过10个字符'],
        ['password','require|confirm','密码必须传递|两次密码不一致'],
        ['mobile','require|number','手机号必填写|手机号必须是数字'],
        ['email', 'require|email','邮箱必填写|邮箱格式错误'],
    ];

    /**场景设置**/
    protected  $scene = [
        'add' => ['name', 'parent_id', 'id'],// 添加
        'listorder' => ['id', 'listorder'], //排序
        'status' => ['id', 'status'],
    ];
