php - SQLSTATE[HY093] : Invalid parameter number: parameter was not defined'

Question

我已经阅读了很多讨论这个问题的线程，但我找不到我的代码有什么问题。我有一个数组:

    $insert_arr["$key"]['customer']["$cust->Company"]['cpq_id'] = "$cust->CustomerId";
    $insert_arr["$key"]['customer']["$cust->Company"]['shop_cart_id'] = "$cust->ShopCartId";
    $insert_arr["$key"]['customer']["$cust->Company"]['user_id'] = "$cust->UserId";
    $insert_arr["$key"]['customer']["$cust->Company"]['company'] = "$cust->Company";
    $insert_arr["$key"]['customer']["$cust->Company"]['crm_id'] = empty("$cust->CRMAccountId") ? 0 : "$cust->CRMAccountId";

稍后，我有:

$q_customer = 'insert into customers
                                 (
                                   cpq_id, 
                                   shopping_cart_id,
                                   user_id,
                                   company_name,
                                   crm_id
                                  )
                                  values (?, ?, ?, ?, ?)';
$sc = $db2->prepare($q_customer);

稍后:

foreach ($insert_arr as $id => $arr) {
    foreach($arr['customer'] as $c) {
            $sc->execute($c);
    }
}

我总是收到标题中引用的错误。我以前从未使用过 PDO，我不知道出了什么问题。请帮忙!

如果您想使用关联数组作为 execute() 的参数，则必须使用命名占位符，而不是 ?。占位符名称必须与数组索引匹配。

$q_customer = 'insert into customers (cpq_id, shopping_cart_id, user_id, company_name, crm_id) values (:cpq_id, :shop_cart_id, :user_id, :company, :crm_id)';
$sc = $db2->prepare($q_customer);
foreach ($insert_arr as $id => $arr) {
    foreach($arr['customer'] as $c) {
            $sc->execute($c);
    }
}
