Function return a 'template call'

[cinq]

I am trying to use a function to return a template call into the main code.

Something along these lines but it does not seem to work ( doesnt seem to return anything )

This is the function

PHP Code:

function showarticle()
{
    global $globaltemplates,$DB_site;
 
$query= $DB_site->query("
        SELECT *
        FROM " . TABLE_PREFIX . "article
        ORDER BY date
    ");

while($art = $DB_site->fetch_array($query))
{
    eval('$artbit .= "' . fetch_template('artbit') . '";'); 
}

return $artbit;
} 


In the main code :

i have

PHP Code:

showarticle();

eval('print_output("' . fetch_template('main') . '");'); 


where in template main, $artbit is used.

But this does not display anything.

Seems simple enough but I am puzzled why it does not work ?
