根据标题，我在将产品添加到购物车时遇到了一个问题：它会显示一个窗口消息，表明产品已添加，但实际上它不在那里。它给出以下错误：
致命错误：无法将stdclass类型的对象用作数组
the line is: <td><?php echo $value['item_name']; ?></td>下面是代码文件reserve.php：
<?php
session_start();
ini_set('display_errors', 1);
$connect = mysqli_connect('127.0.0.1', 'root', '***********', 'Community Garden List');
if (isset($_POST['add'])) {
if (isset($_SESSION['cart'])) {
$item_array_id = array_column($_SESSION['cart'], 'product_id');
if (!in_array($_GET['id'], $item_array_id)) {
$count = count($_SESSION['cart']);
$item_array = array(
'product_id' => $_GET['id'],
'item_name' => $_POST['hidden_name'],
'product_price' => $_POST['hidden_price'],
'item_quantity' => $_POST['quantity'],
);
$_SESSION['cart'][$count] = $item_array;
echo '<script>window.location="reserve.php"</script>';
} else {
echo '<script>alert("Product is already Added to Cart")</script>';
echo '<script>window.location="reserve.php"</script>';
}
} else {
$item_array = array(
'product_id' => $_GET['id'],
'item_name' => $_POST['hidden_name'],
'product_price' => $_POST['hidden_price'],
'item_quantity' => $_POST['quantity'],
);
$_SESSION['cart'][0] = $item_array;
}
}
if (isset($_GET['action'])) {
if ($_GET['action'] == 'delete') {
foreach ($_SESSION['cart'] as $keys => $value) {
if ($value['product_id'] == $_GET['id']) {
unset($_SESSION['cart'][$keys]);

}
}
}

?>html代码
<?php
$query = 'SELECT * FROM product ORDER BY serial ASC';
$result = mysqli_query($connect, $query);
if (mysqli_num_rows($result) > 0) {
while ($row = mysqli_fetch_array($result)) {
?>
<div class="col-md-4">
<form method="post" action="reserve.php?action=add&id='.$row['id'].">
<div style="border: 1px solid #eaeaec; margin: -1px 19px 3px -1px; box-shadow: 0 1px 2px rgba(0,0,0,0.05); padding:10px;" align="center">

</form>
</div>
}
}
?>
<?php
if(!empty($_SESSION["cart"])){
$total = 0;
foreach ($_SESSION["cart"] as $key => $value) {
?>
<tr>
<td><?php echo $value["item_name"]; ?></td>
<td><?php echo $value["item_quantity"]; ?></td>
<td>$ <?php echo $value["product_price"]; ?></td>
<td>
$ <?php echo number_format($value["item_quantity"] * $value["product_price"], 2); ?></td>
<td><a href="Cart.php?action=delete&id=<?php echo $value["product_id"]; ?>"><span
class="text-danger">Remove Item</span></a></td>
</tr>
<?php
$total = $total + ($value["item_quantity"] * $value["product_price"]);
}
?>
<tr>
<td colspan="3" align="right">Total</td>
<th align="right">$ <?php echo number_format($total, 2); ?></th>
<td></td>
</tr>
<?php
}
?>
</table>
</div>
</div>我试过了 print "<pre>"; var_dump($row); exit; 在这行之后： foreach e($_SESSION['cart'] as $key => $value) { 还有一张table NULL 在里面。那是什么意思？
在那之前，我试着改变 $value['item_name'] 与 $value->item_name ，我得到了以下错误：
注意：未定义的属性：stdclass:：$item\u name in
你能帮我弄明白怎么了吗？谢谢您。
