我正在使用PDO而且我找不到那里的错误,即使PDO的setAttribute设置为,也似乎无法收到错误。
$fields = $data['fields'];
$cartID = $data['cartID'];
$sql = "UPDATE ShoppingCart
SET shipToSameLocation_shippingLocationID = :shippingLocationID, shipToSameLocation_shippingMethod = :shippingMethod, shipToSameLocation = 1
WHERE cartID = :cartID";
$query = $conn->prepare($sql);
$query->bindValue(':shippingLocationID', $fields['shipToSameLocation_shippingLocationID'], PDO::PARAM_INT);
$query->bindValue(':shippingMethod', $fields['shipToSameLocation_shippingMethod'], PDO::PARAM_STR);
$query->bindValue(':cartID', $cartID, PDO::PARAM_INT);
$query->execute();
那里有什么问题与PDO有关吗?
答案 0 :(得分:0)
Proabaly,因为你明确地说这个值是int而不是将post值强制转换为int;
$fields = $data['fields'];
$cartID = (int) $data['cartID'];
$sql = "UPDATE ShoppingCart
SET shipToSameLocation_shippingLocationID = :shippingLocationID, shipToSameLocation_shippingMethod = :shippingMethod, shipToSameLocation = 1
WHERE cartID = :cartID";
$query = $conn->prepare($sql);
$query->bindValue(':shippingLocationID', $fields['shipToSameLocation_shippingLocationID'], PDO::PARAM_INT);
$query->bindValue(':shippingMethod', $fields['shipToSameLocation_shippingMethod'], PDO::PARAM_STR);
$query->bindValue(':cartID', $cartID, PDO::PARAM_INT);
$query->execute();
您绑定的其他值也是如此,因此将它们转换为正确的类型,或者更好,但不要使用绑定值。就个人而言,我从不打扰绑定参数或值,我只是将一个关联数组传递给PDO。
$locId = (int) $fields['shipToSameLocation_shippingLocationID'];
$method = $fields['shipToSameLocation_shippingMethod'];
$cartId = (int) $data['cartID'];
$params = array(
':shippingLocationID' => $locId ,
':shippingMethod' => $method,
':cartID' => $cartId
);
$query->execute($params);
每次都像魅力一样。我工作的大多数地方,其他人最终采用这种方法,因为编码和使用它的麻烦要少得多,但这取决于你。
