  {include_php} tags are used to include a php script in your template.
  The path of the attribute file can be
   either absolute, or relative to
   $trusted_dir. If security is enabled, then the 
   script must be located in the $trusted_dir path of the securty policy.
   See the Security section for details.
 
  By default, php files are only included once even if called
  multiple times in the template. You can specify that it should be
  included every time with the once attribute.
  Setting once to FALSE will include the php script each time it is
  included in the template.
 
  You can optionally pass the assign attribute,
  which will specify a template variable name that the output of
  {include_php} will be assigned to instead of
  displayed.
 
  The smarty object is available as $_smarty_tpl->smarty within
  the PHP script that you include.

$this->assign('navigation', $db->getRows());
