Question

我已经阅读了很多讨论这个问题的帖子，我无法找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);

后来还是：

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

我总是得到标题中引用的错误。我之前从未使用过PDO，但我无法弄清楚错误是什么。求救！

Answer 1

您必须先绑定参数才能调用execute方法。您的数组也是第三维类型，因此您需要添加foreach。

像这样：

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

Answer 2

如果要使用关联数组作为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);
    }
}
