Template For Articles Stored In DB - How do I get it out?

I have a template for my pages stored in DreamWeaver. The template uses a mixture of PHP, HTML, and Javascript. I also am creating articles, and each article has its own page created when the article is created (ex: mysite.com/users/exampleuser/2010/03/17/example-article-title.php) so that each article can be indexed by search engines.

In order to change the template of all articles without having to physically change each article, I have the template stored in a DB. Each article's code looks like this:

<?php
	require_once($_SERVER["DOCUMENT_ROOT"] . "/includes/db.php");

	$sql = "SELECT Above_Content, Below_Content FROM templates WHERE ID = '1'";
	$query = mysql_query($sql);
	if ($row = mysql_fetch_assoc($query)) {
		echo eval("?>".$row['Above_Content']);
		//INSERT CONTENT HERE
$sql = "SELECT article_title, article_intro, article_content, author_id, creation_date, last_modified_date FROM articles WHERE article_id = '234'";
				$query = mysql_query($sql);
				if ($row = mysql_fetch_assoc($query)) { ?>
				<div id="display_article">
    			<h1> <?php echo $row['article_title']; ?> </h1>    
   		 		<p><?php echo $row['article_content']; ?></p>
    			</div>
				<?php
				}
						$sql = "SELECT Above_Content, Below_Content FROM templates WHERE ID = '1'";
		$query = mysql_query($sql);
		if ($row = mysql_fetch_assoc($query)) {
			echo eval("?>".$row['Below_Content']);
		}
	}
?>

Code (markup):

Note the use of echo eval() to pull the template from the DB. Is there a better way to do this? I'm having a problem - the entire page (headers and below) are all being displayed "pushed down" from where they should be, as well as my Suckerfish drop-down menu won't work correctly - please note these errors are non-existent on the "real" template. Perhaps my javascript and other things aren't being evaluated properly? What other way can I approach this?

Thanks in advance!

 

/bump, anyone have an ideas as to how to do this? I'm sure its a common thing to do...
