Move record up down

james182 · April 20, 2010

I am trying to get the script to insert the new order into the mysql db but don't know how any help.

below is the working up down list but i need it to save / update the new positions.

<title>test list sort</title>

<script type='text/javascript' src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

<script>
$(document).ready( function () {

   $('table tbody a.control').live('click', function (e) {
	e.preventDefault();

	var tr = $(this); // Start with this link and work upwards from there, this allows the TR element itself to be the control if desired
	var iterations = 0;
	while(tr.attr('tagName') != 'TR') {
		tr = tr.parent();
		iterations += 1;
		if (iterations == 100) {
			return false; // Bail out, surely something is wrong or there is lots and lots of html in there
		}
	}

	if ($(this).attr('rel') == 'up' && tr.prev().length)
		tr.fadeTo('medium', 0.1, function () {
			tr.insertBefore(tr.prev()).fadeTo('fast', 1);
			// If you want to do any more to the table after the move put it here, I am running the reorder function (defined below)
			reorder();

		});
	else if ($(this).attr('rel') == 'down' && tr.next().length)
	   // Same as above only this is for moving elements down instead of up
		tr.fadeTo('fast', 0.1, function () {
			tr.insertAfter(tr.next()).fadeTo('fast', 1);
			// If you want to do any more to the table after the move put it here, I am running the reorder function (defined below)
			reorder();
		});
	else
		//Can't do anything with these
		return false;
	return false;
});

function reorder () {
	var position = 1;
	$('table tbody tr').each(function () {
		// Change the text of the first TD element inside this TR
		$('td:first', $(this)).text(position);
		//Now remove current row class and add the correct one
		$(this).removeClass('row1 row2').addClass( position % 2 ? 'row1' : 'row2');
		position += 1;
	});
}
});

</script>

</head>
<body>


<?php
echo '<table>
	<thead>
		<tr>
   			<th>Position</th><th>Name</th><th>Controls</th>
		</tr>
	</thead>
	<tbody>';

	$con = mysql_connect("localhost", "*******", "*********") or die(mysql_error());	
	mysql_select_db("my_test", $con) or die(mysql_error());

	$sql = "SELECT * FROM tbl_items ORDER BY item_order ASC";
	$result = mysql_query($sql);

	$i = 1;
	while($r = mysql_fetch_assoc($result)):	

	echo '<tr class="'.$i.'">
		<td>'. $i .'</td><td>'. $r['item_name'] .'</td><td> <a href="#up" rel="up" class="control">Up</a> <a href="#down" rel="down" class="control">Down</a></td>
	</tr>';

	$i++;
	endwhile;

echo '</tbody></table>';

?>

</body>
</html>

db table:

item_id | item_name | item_order

---------|--------------|-------------

1 | green | 1

2 | blue | 2

3 | red | 3
