SQLSTATE [HY093]：無效的參數號：參數沒有被定義的」

Question

我讀了一堆線程討論這個問題，我無法找到什麼毛病我code.I有一個數組：

$insert_arr["$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"; 

過了一會兒，我有：

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

後來還是：

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

我總是在T得到引用的錯誤書名。我以前從未使用PDO，但我無法弄清楚什麼是錯的。請幫助！

Answer 1

你必須在調用execute方法之前綁定你的參數。你的數組也是第三維類型，所以你需要添加一個foreach。

像這樣：

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

如果你想使用關聯數組作爲參數​​，你必須使用指定的佔位符，而不是?。佔位符名稱必須與數組索引匹配。

$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); 
    } 
}
