php - 使用 PHP PDO 插入多行

Question

我正在尝试使用 PHP PDO 将两行插入到 MySQL 表中。下面是我的代码

$bundleParams[] = array(
     ':bundle_contract_id' => $contract_id,
     ':bundle_clin' => $clin,
     ':constituent_clin' => $constituent_clin,
     ':constituent_quantity' => $constituent_quantity,
     ':constituent_price' => $constituent_price,
     ':base_clin' => 'Y'
);
$bundleParams[] = array(
     ':bundle_contract_id' => $contract_id,
     ':bundle_clin' => $clin,
     ':constituent_clin' => 'DELL-COMPONENTS',
     ':constituent_quantity' => $constituent_quantity,
     ':constituent_price' => 0.00,
     ':base_clin' => 'N'
);
$insertSQL = "INSERT INTO product_bundle(bundle_contract_id, bundle_clin, constituent_clin, constituent_quantity, constituent_price, base_clin) VALUES (:bundle_contract_id, :bundle_clin, :constituent_clin, :constituent_quantity, :constituent_price, :base_clin)";
$stmt = $pdo->prepare($insertSQL);
$stmt->execute($bundleParams);

当我执行代码时，出现错误

Fatal error: Uncaught exception 'PDOException'

有消息

SQLSTATE[HY093]: Invalid parameter number

这段代码有什么问题？谁能帮我跟踪这个问题吗？非常感谢您抽出宝贵的时间。

$stmt->execute($array); 想要一个与 PDO 绑定(bind)的关联数组，你给出一个这样的数组的数组 -> 你必须为每个数组执行此操作(如你的常识已经说过了):

foreach ($bundleParams as $row)
    $stmt->execute($row);
}
