在php生成的表中，我使用拖放行来更改排序。 （第一张图片，第二张图片....）
如果我首先删除第4行，它将是第一行，但是我删除的行，它保持为第4行，行不会重新编号。
如何重新编号行，并将索引放在名为sorrend_hidden的隐藏输入中？

Jquery：
$("#table_2").tableDnD(
{
onDrop: function(table, row)
{
var rows = table.tBodies[0].rows;
var RowID = row.id.substr(3);
var RowIndex = $(row).index() + 1;
// name = sorrend_hidden
$.ajax({
data: { RowID:RowID, RowIndex:RowIndex },
type: 'POST',
url: 'files/update_slide_index.php',
success: function(data)
{
var result = $.trim(data);
$('#newsletterResult').html(result);
$('#newsletterModal').modal('show');
},
complete: function()
{
setTimeout(function()
{
location.reload();
}, 3000 );
}
});
}
});
Sql update：
<?php
include_once("../../files/connect.php");
if(isset($_POST['RowID']))
{
$RowID = intval($_POST['RowID']);
$RowIndex = intval($_POST['RowIndex']);
$sql = "UPDATE slideshow SET slide_sorrend = '$RowIndex' WHERE slide_id = '$RowID'";
/*if(mysqli_query($kapcs, $sql))
{
mysqli_query($kapcs, "UPDATE slideshow SET slide_sorrend = slide_sorrend + 1 WHERE slide_id != '$RowID'") or die(mysqli_error($kapcs));
}
else
{
die(mysqli_error($kapcs));
}*/
echo 'A kép sorrendje sikeresen megváltozott.';
}
else

echo 'Nincs ID';
}

几个月前我遇到过类似的问题。我最终使用了jQuery UI中包含的可排序功能。
