【问题描述】：

$this->db->select("*");
$this->db->from("panTab");         
$this->db->where("QCJobPanelTestId = ",$TestId);
$query = $this->db->get();
$data['get_JobPan_Data'] = $query->result();

for($i = 0; $i < sizeof($data['get_JobPan_Data']);$i++)
{
$table = "Form1";
$whereField1 = "QC1TestId";
$whereField2 = "QC1JobPanelId";
$currDiv = "form1";
$this->db->select("*");
$this->db->from($table);
$this->db->where($whereField1." = ",$TestId); 
$this->db->where($whereField2." = ",$data['get_JobPan_Data'][$i]['QCJobPanelId']); //--This value gives an error . How to access it?
$query1 = $this->db->get();
$data['getTestData'] = $query1->result();
}

即将到来的数据

 Array ( 
        [get_JobPan_Data] => Array ( 
            [0] => stdClass Object( 
                [QCJobPanelId] => 293 [QCJobPanelNo] => 1 
                [QCJobPanelDesc] => Pan 1 
                [QCJobPanelJobId] => 3 
                [QCJobPanelPanelId] => 0 
                [QCJobPanelTestId] => 63 
            ) 
            [getTestData] => Array ( 
                [0] => stdClass Object ( 
                    [QC1Id] => 77 
                    [QC1JobId] => 3 
                    [QC1TestId] => 63 
                    [QCTestDesc] => 0 
                    [QC1DielectricACC_LC] => 0 
                    [QC1DielectricACC_IRA] => 0 
                    [QCRemark] => Completed 
                    [QCTestedBy] => aa 
                    [QCReviewedBy] => bb 
                    [QCWitnessedBy] => cc 
                    [QC1JobPanelId] => 293 
                    [QCTestCompletionDate] => 2016-07-29 00:00:00 
                    [QC1DateAdded] => 2016-07-29 
                ) 
           )
        )

也无法从$data['getTestData']获得价值：
尝试过：

$data['getTestData'][0]['TestDesc']
$data['getTestData'][0][0]['TestDesc']
$data['getTestData']['TestDesc']

【问题讨论】：

$query1 的输出是什么。是数组还是对象。请检查
如何检查？
$this->db->where("QCJobPanelTestId = $TestId");
尝试调试var_dump($data);，看看$data的格式
然后使用 $data['getTestData'][0]->['TestDesc'] 获取数据

【解决方案1】：

访问 $data 的答案，包括来自 @Anish 和 @Anant 的帮助：

$data['getTestData'][0]->TestDesc
ResultVariable[Array1][Array2]->对象变量

简而言之： - 如果是数组，则使用 []
- 如果是对象，则使用 ->

【解决方案2】：

是的，访问对象有错误

$this->db->where($whereField2." = ",$data['get_JobPan_Data'][$i]['QCJobPanelId']);

替换为

$this->db->where($whereField2." = ",$data['get_JobPan_Data'][$i]->QCJobPanelId);
