本篇文章给大家带来的内容是关于thinkphp5编辑时验证唯一如何解决? 有一定的参考价值,有需要的朋友可以参考一下,希望对你有所帮助。

若定义了相关的验证规则,如:

namespace app\seller\validate;
use think\Validate;
class Goodsmtag extends Validate
{
    protected $rule = [
        'name'  =>  'require|max:25|unique:goodsmtag',
        'sort'  =>  'require|number|unique:goodsmtag',
        'pic'   =>  'require',
    ];

    protected $message  =   [
        'name.require' => '类别名称必须填写',
        'name.max' => '类别名称长度不得大于25位',
        'name.unique' => '类别名称不得重复',
        'sort.require' => '排序数字必须填写',
        'sort.number' => '排序必须为数字',
        'sort.unique' => '排序数字不得重复',
        'img.require' => '必须上传图片',
    ];

    protected $scene = [
        'add'  =>  [
            'name'=>'require|max:25|unique:goodsmtag',
            'sort'=>'require|number|unique:goodsmtag',
            'img'=>'require',
        ],
        'edit'  =>  [
            'name'=>'require|max:25|unique:goodsmtag',
            'sort'=>'require|number|unique:goodsmtag',
        ],
    ];
}

在添加界面验证的时候,提交自身的数据验证正常。
然而在编辑修改的页面验证时,提交自身数据会提示数据重复。

解决方法:
在编辑页面表单把主键id也作为数据传入到验证器中(name要和主键同名)。如:

 public function editOne($id){
        $data = [
            'name' => input('name'),
            'isshow' => $_POST['isshow'],
            'create_time' => time(),
            'sort' => input('sort'),
            'id' => input('id')
        ];
        $file = request()->file('pic');
        if($file){
            $info = $file->move(ROOT_PATH . 'public' . DS . 'uploads');
            if($info){
                $img_src = '/uploads/'.$info->getSaveName();
                $img_src = str_replace('\\','/',$img_src);
                $data['img'] = $img_src;
            }
        }else{
            $old = $this->getOneById($id);
            $data['img'] = $old['img'];
        }
        $validate = \think\Loader::validate('Goodsmtag');
        if(!$validate->scene('edit')->check($data)){
            return $validate->getError();
        }else{
            $res = db("goodsmtag")->where("id=$id")->update($data);
            if($res)
                return true;
            else
                return false;
        }
    }
