在codeigniter现有数组中foreach一个模型

Question

在我的控制器上，我想为另一个模型添加结果到现有数组中。

我的控制器：

public function index()
{
    $getConcerts_previous = $this->concert_model->getAllConcerts('previous');

    foreach($getConcerts_previous as $concert) {
        $hallData = $this->hall_model->getHallbyID($concert->cHall_ID);
        $concert->hHall_ID = isset($hallData) ? $hallData->hID : 'No data';
    }

    $this->render_layout('concerts/index', $this->data);
}

实际上，当我在我看来 @varp_dump 我的“$getConcerts_previous”时，我有：

  public 'cID' => string '45' (length=2)
  public 'cBand_ID' => string '8' (length=1)
  public 'cDate' => string '2018-06-22' (length=10)

我想知道例如如何添加这个 var 转储

  public 'cID' => string '45' (length=2)
  public 'cBand_ID' => string '8' (length=1)
  public 'cDate' => string '2018-06-22' (length=10)
  public 'hHall_ID' => string '1' (length=1)

我的数据库：

Concerts: cID | cName | cPlaceType | cPlaceID
Festivals: fID | fName
Halls: hID | hName

如果cPlaceType = 1，选择cPlaceID的节日，如果cPlaceType = 2，选择cPlaceID的大厅，

Answer 1

试试这个

public function index()
{
$this->data['getConcerts_next'] = $this->concert_model->getAllConcerts('next');

$getConcerts_previous = $this->concert_model->getAllConcerts('previous');

foreach($getConcerts_previous as $concert) {
  if($concert->cPlaceType == 1) {
    $hallData = $this->hall_model->getHallbyID($concert->cPlaceID);        
     //$concert->hHall_ID = isset($hallData) ? $hallData->hID : 'No data';  
     $concert->hallData = $hallData;  
     $concert->festivalData = NULL;
  } else {
    $festivalData = $this->festival_model->getFestivalbyID($concert->cPlaceID);     
     //$concert->hHall_ID =  isset($festivalData) ? $festivalData->fID : 'No data';           
     $concert->hallData = NULL;  
     $concert->festivalData = $festivalData;
  } 
}
var_dump($getConcerts_previous);
//include below line and you can pass data to view;
 $this->data['getConcerts_previous'] = $getConcerts_previous;
 $this->render_layout('concerts/index', $this->data);
}

在模型中

public function getHallById($hallID) { 
  $this->db->where('hID', $hallID); 
  return $this->db->get($this->table)->row(); 
}

public function getFestivalById($hallID) { 
  $this->db->where('fID', $festivalID); 
  return $this->db->get($this->table)->row(); 
}
