Question

我有3张桌子可购物。一个是购物车的购物表。第二是订单表。最后一个是ordersItem表。（这里是所有订单。）我想将id从订单表插入到ordersItem表多个。它有效，但仅在ordersItem上添加一行。我在购物车中添加了更多产品，但是当我添加insertId时，它仅将一行和一种产品添加到ordersItem表中。如果我在没有insertId的情况下使用它，它将正常工作。（它将添加多行）。我该如何正确执行此操作？

控制器：

public function insert(){


            $data = array (

                "ordersItem" => json_encode($this->input->post("serviceId")),

                "ordersCus" => $this->session->userdata('people_id'),

                "ordersStatus" => $this->input->post("status"),

                "ordersDate" => date('Y-m-d H:i:s'),
            );

        $this->db->insert("orders", $data);
        $ordersId = $this->db->insert_id();

        $cusId = $this->session->userdata('people_id');

        $checkout = $this->service_model->checkout($cusId);

        foreach ($checkout as $check) {

            $data = array (

                "ordersItemOrdersId" => $ordersId,

                "ordersItemServiceId" => $check->shoppingServiceId,

                "ordersItemEstateId" => $check->shoppingEstateId,

                "ordersItemVehicleId" => $check->shoppingVehicleId,

                "ordersItemPiece" => $check->shoppingPiece,

                "ordersItemAmount" => $check->shoppingPrice,
            );

            $insert = $this->db->insert("ordersItem", $data);

            if($insert) {

                $this->db->where('shoppingCusId', $cusId);
                $this->db->delete('shopping');

                redirect(base_url("checkout"));


            }else {

                echo "Hata!";

            }

        }


    }

您需要将redirect(base_url("checkout"));移动到foreach循环之外，因为它将运行循环迭代，然后重定向以防止添加更多的行。

伪代码示例：

foreach ($checkout as $check) {
    ...
}

redirect(...);

我还建议您使用事务：

$this->db->trans_start();
foreach ($checkout as $check) {

    $data = array(
        "ordersItemOrdersId" => $ordersId,
        "ordersItemServiceId" => $check->shoppingServiceId,
        "ordersItemEstateId" => $check->shoppingEstateId,
        "ordersItemVehicleId" => $check->shoppingVehicleId,
        "ordersItemPiece" => $check->shoppingPiece,
        "ordersItemAmount" => $check->shoppingPrice,
    );

    $this->db->insert("ordersItem", $data);
}
$this->db->trans_complete();
if ($this->db->trans_status()) {
    $this->db->where('shoppingCusId', $cusId);
    $this->db->delete('shopping');
    redirect(base_url("checkout"));
} else {
    echo "Hata!";
}
