我有一个网站，您可以在其中订购一些门票。如果有人下订单，我希望将订单发送到数据库。我也想把特定的购物车中的物品发送到数据库中。查看我使用的模型：
INSERT INTO DIM_REGION (TOWN, County, District, latitude)
SELECT p.town_city, p.county, p.district, d.latitude
FROM (
SELECT town_city, MAX(county) county, MAX(district) district
FROM DWH_PRICE_PAID_RECORDS
GROUP BY town_city
) p
join dwh_postcodes d on p.town_city = d.town;
这是我在表单中使用的代码：
ORDERS CART ITEMS
id* id
amount order_id*
product_id
quantity
当用户按下按钮转到<form action="index.php?page=cart" method="post" class="">
<table class=" table__nav">
<thead>
<tr>
<th class="p p--bold p--th th--ticket">Ticket</th>
<th class="p p--bold p--th th--name">Name</th>
<th class="p p--bold p--th th--quantity">Quantity</th>
<th class="p p--bold p--th th--price">Price per ticket</th>
<th class="p p--bold p--th th--itemtotal">Item Total</th>
</tr>
</thead>
<tbody>
<?php
$total = 0;
foreach($_SESSION['cart'] as $ticket) {
$ticketTotal = $ticket['ticket']['price'] * $ticket['quantity'];
$total += $ticketTotal;
?>
<tr>
<td>
<?php echo $ticket['ticket']['eye_cart']; ?>
</td>
<td>
<p class = "p--bold"><?php echo $ticket['ticket']['name']; ?></p>
</td>
<td>
<input class = "p td--quantity" type="number" name="quantity[<?php echo $ticket['ticket']['id'];?>]" value="<?php echo $ticket['quantity'];?>" class="replace" required />
</td>
<td>
<p>€<?php echo $ticket['ticket']['price'];?>,-</p>
</td>
<td>
<p>€<?php echo $ticketTotal;?>,-</p>
</td>
<td>
<td class="remove-item"><button type="submit" class="btn remove-from-cart" name="remove" value="<?php echo $ticket['ticket']['id'];?>">×</button></td>
</td>
</tr>
</tbody>
<?php } ?>
</table>
<div class="table__wrap">
<button type="submit" id="update-cart" class="btn btn--cart" name="action" value="update">
<img width="14" height="14" src="./assets/img/refresh.png" alt="refresh">
</button>
</img>
<p class="table__order--total"><span class="span--bold span--bold-no">Total:</span></p>
<p class="table__order--number"><span class="span--bold span--bold-no">€ <?php echo $total ?>,-</span></p>
</div>
<div class="table__wrap table__wrap--end">
<a class="p p__li p__li--light" href="index.php?page=register">
<button type = "submit" name ="action" value = "details" class="btn btn--big btn--big-2 btn--dark">your details -> </button></a>
</div>
</form>
时，我想保存一个订单，该订单的总金额+购物车物品的order_id和数量。
我正在为此使用"your details"模型，但我真的无法弄清楚。
这是我的控制器的外观：
MVC下一个代码是我的DAO：
if ($_POST['action'] == 'details') {
$data = array(
'amount' => $total,
);
$insertedOrder = $this->orderDAO->insertOrder($data);
$this->set('insertedOrder', $insertedOrder);
if (empty($insertedOrder)) {
$errors = $this->orderDAO->validate($data);
$this->set('errors', $errors);
}
}
if ($_POST['action'] == 'details') {
$dataB= array(
'order_id' => ?,
'product_id' => $_SESSION['cart']['id']['ticket']['id'],
'quantity' => $_SESSION['cart']['quantity'],
);
$insertedCartItem = $this->orderDAO->insertCartItem($data);
$this->set('insertedCartItem', $insertedCartItem);
if (empty($insertedCartItem)) {
$errors = $this->orderDAO->validateB($dataB);
$this->set('errors', $errors);
}
}
我遇到的主要问题是，我不知道如何将数据从$ _SESSION变量发送到数据库。我在控制器中遇到问题。如您所见，我正在使用$ data和$ dataB发送数据，但是我认为我在这里出错了。
