doubt with controllers

[eluser]kmil0[/eluser]
Hi guys!


I am creating an application to understand how
CodeIgniter works, and I doubt has arisen.

Suppose that the application has a menu and a dynamic main <div>, in the menu the links are read
from a database, and this menu is constant except when it adds a new link from a form.

every time you reload the page (whatever the controller), I suppose that the menu should be read what is new in the database. but, how can I do this if CodenIgniter just let me load one controller?

can I execute a external function from the template (the main view) to show the "links" ?

something like.

<template>
<menu>
&lt;?php showLinks(); ?&gt;
</menu>

<dynamicdiv>
// dynamic content
</div>
</templte>

thanks for help.
excuse my bad english
