我需要在model里讀取到這個(gè)值，讀到的為null

控制器里是這樣賦值的
$goods = new GoodsModel();

$goods->_user = 1231;//賦值用戶(hù)數(shù)據(jù)

$detail = $goods->getGoodsDetail($goods_id);

model里

namespace app\api\v1\model;
use think\Model;

class Goods extends Model
{
protected $name = 'skus';//定義表名
public $_user;//定義用戶(hù)數(shù)據(jù)

public function getPriceAttr($value)
{

    $value = $this->_user;  //取值

    return $value;

}

}

$goods = new GoodsModel();

$goods->_user = 1231;//賦值用戶(hù)數(shù)據(jù)

$detail = $goods->getGoodsDetail($goods_id);
$detail->price; // 值是什么

$detail->_user = 1231;
$detail->price; // 值是什么

商品價(jià)格，浮點(diǎn)型的

你能否照我上面的代碼跑一下,看看輸出的值?
你能否貼貼你這個(gè)getGoodsDetail的具體代碼?

好像是在模型里里定義變量，就沒(méi)辦法夸方法讀取

是用think-orm的獲取讀取$_user然后對(duì)價(jià)格重新計(jì)算

大哥您這個(gè)問(wèn)題我解決不了,您另請(qǐng)高明吧

控制器代碼
public function getGoodsDetail(Request $request)
{

$source = $request->post('source',9);

$goods_id = $request->post('goods_id');

switch ($source) {

    case 1:

        break;
    default:

        $goods = new GoodsModel();

        $goods->_user = 1231;

        $detail = $goods->getGoodsDetail($goods_id);

        break;
}

return json(['code'=>0,'data'=>$detail,'msg'=>'獲取成功']);

}
模型代碼
<?php
namespace app\api\v1\model;
use Exception;
use think\Model;

class Goods extends Model
{

 protected $name = 'skus';

 public $_user;

public function getGoodsDetail($goods_id)
{

  try {

      $detail =$this->where(['sku'=>$goods_id])->withoutField('state,status_id,created_at,,created_at')->find();

      return $detail;

  } catch (Exception $e) {

       return json(['code'=>-1,'data'=>null,'msg'=>'服務(wù)異常，請(qǐng)聯(lián)系管理員處理！']);

  }

}

public function getPriceAttr($value)
{

    $value =$value * $this->user;
    return $value;

 }

}

user 放到初始化看看行不

getGoodsDetail($goods_id) 打印這個(gè)看看是不是模型實(shí)例的（原始）數(shù)據(jù),如果不是 獲取器是不生效的. 用動(dòng)態(tài)獲取器
User::withAttr('name', function($value, $data) {
return strtolower($value);
})->select();
這樣的試試 . 還不行就手動(dòng)吧

你在getGoodsDetail()里返回的是一個(gè)新的model,不是你上面的new GoodsModel(), $_user沒(méi)賦值當(dāng)然是null;

$goods = new GoodsModel();
$goods->_user = 1231;  // 這里賦值針對(duì)的是$goods

$detail = $goods->getGoodsDetail($goods_id);  // 這里是新的model.即$detail
$detail->_user = 1231; // 這樣才算給model(即$detail)賦值
$detail->price; 

你可以嘗試把getGoodsDetail改成,不用ThinkORM,沒(méi)做測(cè)試驗(yàn)證

public function getGoodsDetail($goods_id)
 try {

      $detail =$this->where(['sku'=>$goods_id])->withoutField('state,status_id,created_at,,created_at')->find();
      $detail->_user = $this->_user;

      return $detail;

  } catch (Exception $e) {

       return json(['code'=>-1,'data'=>null,'msg'=>'服務(wù)異常，請(qǐng)聯(lián)系管理員處理！']);

  }
}
// 控制器
$goods = new GoodsModel();
$goods->_user = 1231;
$detail = $goods->getGoodsDetail($goods_id);
echo $detail->price;

下次問(wèn)問(wèn)題盡量貼全代碼,不要弄得語(yǔ)焉不詳,溝通起來(lái)累得不行,本來(lái)幾分鐘的事情,浪費(fèi)大家那么多時(shí)間
