PHP和SQL WHERE（更改變量）

Question

美好的一天，我在這段代碼中苦苦掙扎。
結果“ 10”設置為$ fod，但是需要替換它以顯示被調用行的ID，以便SQL WHERE可以在相關行中列出正確的數據。 請參閱圖像以獲得我得到的結果。

查看當前結果和所需結果
如您所見，我需要ROW ID 10來顯示10的項目，而ROW ID 11來顯示11的項目。 請幫幫我，我怎么稱呼這些行才能正確顯示？
調用函數：
Controller.php這樣

$data['order_list'] = $this->product->data_ordershalf();
$fod = 10;
$data['order_listfull'] = $this->product->data_ordersfull($fod);

的functions.php：

function data_ordershalf(){
    $this->db->select('*');
    $this->db->join('order_detail', 'order_detail.orderid=orders.id', 'left');
    $this->db->join('customers', 'customers.id=orders.customerid', 'left');
    $this->db->join('testshop_products', 'testshop_products.product_id=order_detail.productid', 'left');
    $this->db->from('orders');
    $this->db->group_by('orderid');
    $rs = $this->db->get();
    return $rs->result_array();
}
function data_ordersfull($fod){
    $this->db->select('*');
    $this->db->join('orders', 'orders.id=order_detail.orderid', 'left');
    $this->db->join('testshop_products', 'testshop_products.product_id=order_detail.productid', 'left');
    $this->db->from('order_detail');
    $this->db->where('orderid',$fod);
    $rs = $this->db->get();
    return $rs->result_array();

View.php：

<?php if(!$order_list){ ?>
<tbody>
    <tr>
        <th colspan="7"><center>No orders placed</center></th>
    </tr>
</tbody>
<?php } else { $sr = 1; ?>
<tbody>
    <?php foreach( $order_list as $row) { ?>
    <tr>
        <th scope="row"><?php echo $row['id']; ?></th>
        <td><?php echo $row['date']; ?></td>
        <td><?php echo $row['name']; ?></td>
        <td>
            <table>
                <?php foreach( $order_listfull as $row2) { ?>
                <tr>
                    <th scope="row"><?php echo $row2['id']; ?></th>
                    <td><?php echo $row2['product_name']; ?></td>
                    <td><?php echo $row2['quantity']; ?></td>
                    <td></td>
                    <td><?php echo $row2['price']; ?></td>
                 </tr>
                <?php } ?>
            </table>
        </td>
        <td><?php echo $row['quantity']; ?></td>
        <td><?php echo $row['price']; ?></td>
    </tr>
    <?php } ?>
</tbody>
<?php } ?>

您可以創建幫助程序並將其放在以下功能中。

function data_ordersfull($fod){
    $this->db->select('*');
    $this->db->join('orders', 'orders.id=order_detail.orderid', 'left');
    $this->db->join('testshop_products', 'testshop_products.product_id=order_detail.productid', 'left');
    $this->db->from('order_detail');
    $this->db->where('orderid',$fod);
    $rs = $this->db->get();
    return $rs->result_array();
}
