MYSQL - PHP Record Update problem

I have a MYSQL table called 'news' that has the following fields:



With the following code, I was hoping to be able to insert a new record and have the 'order' field automatically increment on any conflicting records and all other ascending records.  Basically allowing a reorder of the records during the insertion of a new record.  

By this, I mean, if the order already exists in the table, it and all other ascending records would be incremented by one before the new record is inserted.

The records are being inserted into the table but the reorder is not happening, what am I doing wrong?

The first function is addnews and is called from a submit.

<?php

function addnews($message, $order, $active) {
	$message = mysql_real_escape_string($message);
	$order = mysql_real_escape_string($order);
	if (orderexists($order, $active) === true) {
		$pass = orderrenum($order, $active);
	}
	$sql = "INSERT INTO news VALUES ('','$message', '$order', '1')";
	$result = mysql_query($sql);
	mysql_close();
	if (!empty($result)) {
		return true;
	} else {
		return $result;
	}
}

function orderexists($order, $active) {
	$sql = "SELECT order FROM news WHERE order= " . $order . " AND active = 1";
	$result = mysql_query($sql);
	$num = mysql_numrows($result);
	if ($num > 0) {
		return true;
	} else {
		return false;
	}
}

function orderrenum($order, $active) {
	$sql = "SELECT id, order FROM news WHERE order >= " . $order . " AND active = 1";
	$result = mysql_query($sql);
	while ($row = mysql_fetch_assoc($result)) {
		$sql = "UPDATE news SET order = " . $row['order']+1 . " WHERE id = " . $row['id'];
		$result = mysql_query($sql);
	}
}
?>
