Question

我从数据库中获取表数据并将其显示在db中，但是出现问题。管理员添加测验标记时，动态创建数据库中的测验列。现在，当我无法显示针对测验标题的每一列的数据时。

我可以使用foreach在标记中显示测验编号，但是我无法针对该测验显示标记。请引导我。

var x = new String(variabledatahere)

//Manage Grades_model.php

public function GetAllQuizMarks()
    {
    	$this->db->select('*');
        $this->db->from('quizmarks');
        
        $query = $this->db->get();
       	return $query->result();
    }

//ManageGrades.php

//this is controller

public function GetAllQuizMarks()
    {
        $data['markslist']=$this->ManageGrades_model->GetAllQuizMarks();
        
        $this->load->view('Manage/GetAllQuizMarks',$data);
    }
