我正在使用jQuery和ajax有一个拖放式可排序表。Php查询在循环中不更新数据库
我的问题是,它只能工作大约10%的时间。
这是我的js代码。
<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>
这里是tow_sort2.php页:
<?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);
?>
这里是正在打印数组:
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')
当它不起作用时,您是否收到任何错误消息? –
