Template help

[Serge]

Ok i'm having a bit of a problem. I tried to make my own template function to call my templates for my website where here is what I got:

The gettemplate function:

PHP Code:

/////////////////// Start Gettemplate //////////////////
function gettemplate($templatename) {
//Get template from database
$template = mysql_query("SELECT template FROM template WHERE title = '".addslashes($templatename)."'") or
        die (mysql_error());
$template_body = mysql_fetch_array($template);
return str_replace("\\'", "'", addslashes($template_body['template']));
} 


The call for the template inside a webpage:

PHP Code:

eval("\$header = \"".gettemplate('main_head')."\";"); 


I have that exact thing in index.php on my site but when I call up index.php it shows nothing.

Could anyone help me on why when I call the templates they arn't showing up?
