Question

I seen this solution for someones problem but what I dont understand is what should be written in the saveSortable.php file.

Anyone shed some light?

<ul id="sortable">
    <li id="1">elem 1</li>
    <li id="2">elem 2</li>
    <li id="3">elem 3</li>
    <li id="4">elem 4</li>
</ul>

$(document).ready(function(){
    $('#sortable').sortable({
        update: function(event, ui) {
            var newOrder = $(this).sortable('toArray').toString();
            $.get('saveSortable.php', {order:newOrder});
        }
    });
});

You can have something like this:

//do database connection here

$orders =  explode(',',$_GET['order']);
foreach ($orders as $key=>$value) {
$query = "UPDATE `tabel_name`
SET sort_order = {$value}
WHERE id = {$key}";
mysql_query($query) or die('Error, insert query failed');
}
