验证场景问题

Question

/application/admin/validate/Category.php 代码

<?php
namespace app\admin\validate;
use think\Validate;
class Category extends Validate{
    protected $rule = [
         ['name','require|max:10','分类不能为空！|分类名不能超过10！'],
         ['parent_id','number'],
         ['id','number'],
         ['status','number|in:-1,0,1','状态必须为数字|状态范围不合法！'],
         ['listorder','number'],
    ];
    /*验证场景设置*/
    protected $sence = [
        'add' => ['name','parent_id','id'],
        'listorder' => ['id', 'listorder'],
        'status' => ['id', 'status'],
    ];
}
?>

/application/admin/controller/Category.php 代码

<?php
namespace app\admin\controller;

        }
        //把$data数据提交给model层
        $res = $this->obj->add($data);
        if($res){

        }else{
            $this->error('新增失败！');
        }
    }
    public function edit($id = 0){
        if(intval($id)<1){
            $this->error('参数不合法');
        }
        $category = $this->obj->get($id);
        $categorys = $this->obj->getNormalFirstCategory();
        $this->assign('category', $category);
        $this->assign('categorys', $categorys);
        return $this->fetch();
    }

    public function update($data){
        $res = $this->obj->save($data,['id' => intval($data['id'])]);
        if($res){
            $this->success('更新成功');
        }else{
            $this->error('更新失败');
        }
    }
    public function listorder($id,$listorder){
        $res = $this->obj->save(['listorder'=>$listorder],['id'=>$id]);
        if($res){
            $this->result($_SERVER['HTTP_REFERER'],1,'更新成功');
        }else{

删除和修改状态时总是提醒：分类不能为空！

亲爱的同学您好。遇到这种问题 ，老师教您下排查问题的思路

1、 您应该在 删除和修改状态的控制器入口 打印 传递的这个分类出来看看 输出什么内容？

  好的。。

  点击审核按钮：Array ( [id] => 6 [status] => 0 ) 
  点击删除按钮：Array ( [id] => 6 [status] => -1 ) 
  我感觉是这个代码没生效：
  $validate = validate('Category');
  $validate->scene('status')->check($data);
  
  删除以下代码就可以正常更新状态了，
          $validate = validate('Category');
          $validate->scene('status')->check($data);
          if(!$validate->scene('status')->check($data)){
              $this->error($validate->getError());
          }
  所以我判断是验证场景 配置出问题了，请老师指导指正
