如何在codeigniter

Question

我希望能够在应用程序的任何位置显示表中的属性，并让用户对其进行编辑。这意味着数据将来自数据库中的一行。每列都有一个默认值，如果他们愿意，可以由用户更改。

表格列可能如下所示：

| id | admin_id |从业者|从业者|学生|学生|等等...

这是我的模特：

class Lang_trans_model extends CI_Model {

public function get_lang_trans($admin_id){
    $this->db->where('admin_id', $admin_id);
    $query = $this->db->get('lang_trans');
    return $query->row();
    } 

这是我的MY_Controller：

class MY_Controller extends CI_Controller {


public function __construct() {
    parent::__construct();

    $this->load->model('key_items_model');
    $this->load->model('lang_trans_model');

    foreach ($this->key_items_model->get_key_items() as $result){
        $this->label[$result->key] = $result->value;
    }

    //$admin_id = $this->session->userdata('admin_id');
    $admin_id = 3;

    $lang = $this->lang_trans_model->get_lang_trans($admin_id);
    //not sure what should go here????
    //I want to be able to use $lang->practitioner; to be able to have practitioner, or the edited attribute to show on the page

var_dump($lang);
// produces the following:
//object(stdClass)[26]
//public 'id' => string '3' (length=1)
//public 'admin_id' => string '3' (length=1)
//public 'practitioner' => string 'blah' (length=4)
//public 'practitioners' => string 'blahplural' (length=10)

如何完成MY_Controller以便能够在我的应用程序中的任何位置使用这些数据字段？

我不介意使用面向对象的语法或数组语法。哪个更容易。我无法弄清楚如何在每个视图中不使用foreach语句来显示字段。我想用$ lang-＆gt;从业者调用数据;视图中的格式。

提前致谢。

声明父类属性。比从子类中调用它：

class MY_Controller extends CI_Controller
{
    public $lang;//parent variable declared

    public function __construct() 
    {
        parent::__construct();

        $this->load->model('key_items_model');
        $this->load->model('lang_trans_model');

        foreach ($this->key_items_model->get_key_items() as $result) {
            $this->label[$result->key] = $result->value;
        }

        //$admin_id = $this->session->userdata('admin_id');
        $admin_id = 3;

        //dedicating value to variable
        $this->lang = $this->lang_trans_model->get_lang_trans($admin_id);
    }
}

儿童控制器：

class Practitioners extends MY_Controller
{
    public function __construct()
    {
        parent::__construct();
        // no need to call model if it is called in parent controller
    }

    public function index()
    {
        var_dump($this->lang);
    }
}
