我有一个看起来像这样的数组：
Array
(
[currency] => GBP
[shipping] => 3.5
[tax] => 0
[taxRate] => 0
[itemCount] => 3
[item_name_1] => Proletarian Sparrow
[item_quantity_1] => 2
[item_price_1] => 75
[item_name_2] => Guillemot Colony
[item_quantity_2] => 5
[item_price_2] => 20
[item_name_3] => Dandelion Clock
[item_quantity_3] => 2
[item_price_3] => 50
)
我正在尝试使用循环来提取单个项目的详细信息，并在数据库中为每个项目插入一行。我正在使用 Codeigniter。
我的模型如下所示：
public function set_order($cust_id, $order_data)
{
// Breaks up order information and creates a new row in the pn_orders tables for each item
// Get the last row in the orders table so we can work out the next order_id
$this->db->order_by('order_id', 'desc');
$this->db->limit(1);
$query = $this->db->get('pn_orders');
$row = $query->row_array();
// If the resulting array is empty, there are no orders so we can set the order_id to 1. If there is already an order_id, just add 1 to it.
if (empty($row)) {
$order_id = 1;
} else {
$order_id = $row['order_id'] + 1;
}
//echo "<pre>";
//print_r($order_data);
//echo "</pre>";
// The delivery message input has a placeholder. if the user's input is different to this, assign it to $delivery_message.
if ($this->input->post('delivery_message') == "e.g. if out, leave in porch") {
$delivery_message = NULL;
} else {
$delivery_message = $this->input->post('delivery_message');
}
// Set today's date for insertion into the DB
$date = date('Y-m-d');
// The order information is clumped together in a single array. We have to split out single items by looping through the array before inserting them into the DB.
for ($i = 1; $i <= $order_data['itemCount']; $i++) {
$item = array(
'order_id' => $order_id,
'cust_id' => $cust_id,
'date_ordered' => $date,
'item_name' => $order_data["item_name_{$i}"],
'item_quantity' => $order_data["item_quantity_{$i}"],
'item_price' => $order_data["item_price_{$i}"],
'payment_method' => $_POST['payment_method'],
'delivery_message' => $delivery_message
);
$this->db->insert('pn_orders', $item);
}
}
一切似乎都到位，但是，只插入了 1 行，我不知道为什么。看起来很简单。
它与 Activerecord 模式有关吗？
谢谢。
