foreach连接foreach并选择SUM

Question

如何在查询WHERE中使用另一个foreach连接foreach。 我已经在第二个Foreach中存储了带有第一个ID的ID的内容，并且希望在相应的列中显示它。 因此，如果在第二列db_buy.tb_buy_shop具有ID 2，本应显示在HTML的列，其中db_shop.tb_shop_id 2.

视图：

<?php 
    foreach ($shops_where_1 as $shop_where_1): 
     foreach ($buy_sums as $buy_sum): 
      if($buy_sum['tb_buy_shop']==$shop_where_1['tb_shop_id']) { 
       $gesamtsumme = $buy_sum['gesamtsumme']; 
      } 
     endforeach; 
?> 
     <tr> 
      <td><?php echo $shop_where_1['tb_shop_name']; ?></td> 
      <td></td> 
      <td><div class="input-group"><div class="input-group-addon">€</div><input type="text" class="form-control" value="<?php echo number_format($buy_sum['gesamtsumme'],2,",",".");?>" disabled></div></td> 
      <td><div class="input-group"><div class="input-group-addon">€</div><input type="text" class="form-control" value="<?php echo number_format($gesamtsumme,2,",",".");?>" disabled></div></td> 
      <td></td> 
      <td></td> 
     </tr> 
<?php 
     // endforeach; 
    endforeach; 
?> 

型号：

public function shops_where_1() 
{ 
    $this->db->select('*'); 
    $this->db->from('db_shop'); 
    $this->db->where('db_shop.tb_shop_buy = 1'); 
    $this->db->order_by('tb_shop_name'); 
    $query = $this->db->get(); 
    return $query->result_array(); 
} 

public function buy_sums() 
{ 
    $this->db->select('(SELECT SUM(db_buy.tb_buy_gesamt) FROM db_buy) AS gesamtsumme'); 
    $this->db->select('(SELECT SUM(db_buy.tb_buy_abbezahlt) FROM db_buy) AS abbezahlt', FALSE); 
    $this->db->select('tb_buy_shop'); 
    $this->db->from('db_buy'); 
    $query = $this->db->get(); 
    return $query->result_array(); 
} 

控制器：

public function buy_shop($slug) 
{ 
    // if (!$this->session->userdata('logged_in')) 
     // { 
      // redirect('users/login'); 
     // } 
    $data['get_shops'] = $this->Admin_model->get_shops($slug); 
    $data['shops_where_1'] = $this->Admin_model->shops_where_1(); 
    $this->load->view('templates/header_acp'); 
    $this->load->view('admin/buy_shop', $data); 
    $this->load->view('templates/footer'); 
} 

Answer 1

如果我在你所问的问题上正确，你似乎只是想知道如何格式化代码，以便它会建立表格。这将是如何做到这一点。

<?php 
foreach ($shops_where_1 as $shop_where_1): 
?> <tr> 
    <td><?php echo $shop_where_1['tb_shop_name']; ?></td> 
<?php 
    foreach ($buy_sums as $buy_sum): 
     if($buy_sum['tb_buy_shop']==$shop_where_1['tb_shop_id']) { 
      ?> 
     <td><div class="input-group"><div class="input-group-addon">€</div><input type="text" class="form-control" value="<?php echo number_format($buy_sum['gesamtsumme'],2,",",".");?>" readonly></div></td> 
<?php 
     } 
    endforeach; // endforeach 2 
    </tr> 
endforeach; // endforeach 1; 
?> 

Answer 2

不幸的是，没有。第二个foreach的总和不正确。从商店ID 3只有10.00出，但它来102.31 enter image description here
