我正在使用jQuery和ajax有一個拖放式可排序表。Php查詢在循環中不更新數據庫
我的問題是,它只能工作大約10%的時間。
這是我的js代碼。
<script type="text/javascript">
// When the document is ready set up our sortable with it's inherant function(s)
$(document).ready(function() {
$("#test-list").sortable({
handle : '.handle',
update : function() {
var order = $('#test-list').sortable('serialize');
$("#info").load("tow_sort2.php?"+order);
}
});
});
</script>
這裏是tow_sort2.php頁:
<?php
include("../_includes/db_connection.php");
/**
* This is where you would inject your sql into the database
* but we're just going to format it and send it back
*/
$array =array();
foreach ($_GET['listItem'] as $position => $item)
{
$sql = "UPDATE tow SET tow_order = '$position' WHERE tow_id = '$item'";
$conn->query($sql);
$array[] = $sql;
}
print_r($array);
?>
這裏是正在打印數組:
Array ([0] => UPDATE tow SET tow_order = '0' WHERE tow_id = '5924' [1] => UPDATE tow SET tow_order = '1' WHERE tow_id = '5925' [2] => UPDATE tow SET tow_order = '2' WHERE tow_id = '5922' [3] => UPDATE tow SET tow_order = '3' WHERE tow_id = '5923')
當它不起作用時,您是否收到任何錯誤消息? –
什麼是數據庫提供者?如何管理交易? – soyuka
預期行爲是什麼?它究竟如何不工作? – BPS
