Deal Widget for WordPress MU

I created a widget to display ads related to the posts on my deals blog. The purpose of this widget is to display my affiliate links on all the blogs sidebar

function kish_get_deals() {
	global $blog_id;
	$current_blog=$blog_id;
	$dealblogid=8;
	switch_to_blog($dealblogid);
	global $post;
	$myposts = get_posts('numberposts=5&orderby=rand');
	?>
<h4 class="widget">Deals - Check it out</h4>
<div style="margin: 5px;background: none transparent scroll repeat 0% 0%;padding: 5px">
	<?php
	foreach($myposts as $post) :
	   setup_postdata($post);
	?>
<div style="margin-top: 3px">
	<li><a href="<?php editable_post_meta($post->ID, " target="_blank">"><?php editable_post_meta($post->ID, "dtitle"); ?></a>

<?php editable_post_meta($post->ID, "ddesc"); ?>

<?php editable_post_meta($post->ID, "durl"); ?><a title="Permanent Link to <?php the_title(); ?>" rel="bookmark" href="<?php the_permalink() ?>"> ¶</a>

</li>
</div>
<?php endforeach;?></div>
<?php switch_to_blog($current_blog);
}

You need to manually add the post_meta fields (custom fields) for those particular blog posts. As I am using the front end editor, I have used the different function, you can change that to get_post_meta function instead. You can add this to your sidebar and if you are using thesis theme, add it to your custom functions.php
