Sorting Product Pages

Hi guys,

Long time troll. First time poster. Apologies if there is a thread for this. I’m working on a website for a friend and trying to get the product pages to sort alphabetically. I’ve tried using codes provided in other threads but to no avail.

I want these products to sort alphabetically in ascending order (I.E: 240, 260, 300, 400, Cyclone, etc).

<?php
    function getParents($id) {
	    global $wpdb;
	    $posts_table = $wpdb->prefix . "posts";
	    $parent_id = $wpdb->get_var("SELECT post_parent FROM $posts_table WHERE ID=$id");
	    if($parent_id == 0) return '';
	    $parent = get_post($parent_id);
	    return getParents($parent_id) . '<a href="'. get_permalink($parent_id) .
	    	"\" title=\"$parent->post_title\">$parent->post_title</a> > ";
    }
    ?>

	<!-- LOOP -->
<?php if (have_posts()) : ?>

		<?php while (have_posts()) : the_post(); ?>
				<h2><?php global $post; echo getParents($post->ID); ?>
						   <a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>

		<!-- Display Subpages & Products -->
				<ul id="productlist">
				<?php
				$children = get_children("post_type=page&post_parent=$post->ID&order=ASC");
				foreach ($children as $child):
				?>
					<li>
						<a href="<?php echo get_permalink($child->ID) ?>" title="<?php echo $child->post_title ?>">
						<img src="<?php echo get_post_meta($child->ID, "Product Image", true) ?>" />
						<span><?php echo $child->post_title ?></span></a>
					</li>
				<?php endforeach; ?>
				</ul>
		<?php endwhile; ?>

	<?php else : ?>

Any help would be much appreciated.
