Insert multiple values from API into mysql databas

问题:

I am connected to an API that keeps track of customer orders. Some orders have one product but some orders have multiple products in one order. When I try and INSERT into my database I only get the first product. I would like to have all the products inserted in the cases where their are more than one. The API's XML to the productName is ->orderItems->orderItem->productName and I am trying to loop through all of them but I still only get the first product.

foreach ($customer_orders as $customer_order) {
    $chOrder = curl_init('https://' . $customer_order->reference);
    curl_setopt($chOrder, CURLOPT_USERPWD, "username" . ":" . "password");
    curl_setopt($chOrder, CURLOPT_HTTPHEADER, array('Content-Type: application/xml'));
    curl_setopt($chOrder, CURLOPT_RETURNTRANSFER, true);
    $orderResult = curl_exec($chOrder);
    curl_close($chOrder);

    $shouldContinue = true;
    try {
        $singleXML = new SimpleXMLElement($orderResult);
    } catch (Exception $e) {
        $shouldContinue = false;
        error_log($e);
        error_log('Failed to get history for ' . wp_get_current_user()->user_email . ' using refernece: ' .  $customer_order->reference);
    }

    if ($shouldContinue) {

        ++$orderCount;


        foreach ($singleXML->orderItems->orderItem as $item) {
            $product = htmlentities($item->productName, ENT_QUOTES, 'UTF-8');
        }


        $con = mysqli_connect('localhost', 'root', 'password', 'database');

        $query = "INSERT IGNORE INTO customer_product_list(`product`)VALUES('$product')";

        mysqli_query($con, $query);

        mysqli_close($con);
    }
}

回答1:

try put insert query inside foreach loop

$con = mysqli_connect('localhost','root','password','database');
foreach ( $singleXML->orderItems->orderItem as $item ) {
    $product = htmlentities($item->productName, ENT_QUOTES, 'UTF-8');
    $query = "INSERT IGNORE INTO customer_product_list(`product`) VALUES('$product')";

    mysqli_query($con,$query);     
}
mysqli_close($con);
