Why make it so hard? You can keep it as simple as it just is (this requires javascript for the drag-and-drop). I roll out (using PHP): <ul> <li><a href="http://link1">mylink #{$pos}</a> <input type="hidden" name="links[]"></li> <li><a href="http://link2">mylink #{$pos}</a> <input type="hidden" name="links[]"></li> <li><a href="http://link3">mylink #{$pos}</a> <input type="hidden" name="links[]"></li> <li><a href="http://link4">mylink #{$pos}</a> <input type="hidden" name="links[]"></li> <li><a href="http://link5">mylink #{$pos}</a> <input type="hidden" name="links[]"></li> </ul> Then the user modifies these by dragging and dropping them into the new order: <ul> <li><a href="http://link1">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> <li><a href="http://link3">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> <li><a href="http://link4">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> <li><a href="http://link2">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> <li><a href="http://link5">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> </ul> Then I use: $links = $_POST['links']; $sizeof = sizeof($links); for ($i = 0; $i < $sizeof; ++$i) { $id = $links[$i]; $query = "UPDATE links SET position = $i WHERE id = $id"; //.. } I roll out just like I did before: <ul> <li><a href="http://link1">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> <li><a href="http://link3">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> <li><a href="http://link4">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> <li><a href="http://link2">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> <li><a href="http://link5">mylink #{$pos}</a> <input type="hidden" name="links[]" value="{$id}"></li> </ul> The links in the new order.
