我在会话中从表单[]中存储了一些多个id值。
我尝试在mysql pdo数据库查询中使用这些id,如下所示:
$noot = str_repeat("?,", count($_SESSION['uniqueID'])-1) . "?";
$printen = 1;
$query = $db->prepare("SELECT DISTINCT ru.GB,g.Name,g.Address,g.Place,ri.Ricode,lo.nr,lo.uniqueID,GROUP_CONCAT(ru.control SEPARATOR '<BR>') AS control,GROUP_CONCAT(ru.BestEmail SEPARATOR '<BR>') AS email,GROUP_CONCAT(ru.ont_info SEPARATOR '<BR>') AS ont,GROUP_CONCAT(ru.sup SEPARATOR '<BR>') AS Lev,GROUP_CONCAT(ru.OrderID SEPARATOR '<BR>') AS orderID,GROUP_CONCAT(DISTINCT ru.rID SEPARATOR '<BR>') AS RID,GROUP_CONCAT(ru.Pack SEPARATOR '<BR>') AS packet FROM rutrans AS ru JOIN routes AS ri ON ru.rID = ri.rID
LEFT OUTER JOIN lock AS lo
ON ri.Ricode = lo.ricode AND ru.GB = lo.location
LEFT OUTER JOIN gbc AS g
ON ru.GB = g.CodeB
WHERE lo.uniqueID IN ($noot)");
$query->execute($_SESSION['uniqueID']);
//$data = $query->fetchAll();
尝试得到这样的结果:
foreach($queryRT as $rowRT) {
(I echo database results within a table for each row here,... or try to do this)
}
发生以下错误:
致命错误:带有消息的未捕获异常'PDOException' 'SQLSTATE [HY093]:
中的参数号无效
当我添加
$data = $query->fetchAll();
查询页面完全空白。
当我尝试这样的事情时:
print_r($data);
页面上仅显示以下内容:
Array()
当我尝试这样的事情时:
print_r($_SESSION['uniqueID']);
它显示如下数组:
Array ( [B1601222016164345] => B1601222016164345
[B1601222016161121] => B1601222016161121
[B1601262126474345] => B1601262126474345
[B1602011856554345] => B1602011856554345
[B1602101921434345] => B1602101921434345
[Z1602102002034345] => Z1602102002034345
[Z1602102026544345] => Z1602102026544345
)
显然我做错了。 是否有人有想法解决这个问题?
答案 0 :(得分:3)
$_SESSION['uniqueID']
作为占位符, ?
需要为其索引编号。
input_parameters中的键必须与SQL中声明的键匹配。在PHP 5.2.0之前,它被默默地忽略了。
试试这个:
$query->execute(array_values($_SESSION['uniqueID']));
