Mechanism

When a page is called:

• The script alahup/_main.php is called.

  It's responsible for displaying the main template.

  By default, it contains this :

  alahup/_main.php :
  $alahup->smarty->display('main.tpl');

  This line simply tells alahup! to proccess and display the template file called main.tpl.

  It's a good place to implement custom user identification, custom redirection, caching, template switching, ...

• The main template is processed and displayed.

  The content blocks invoked from the main template (with {$alahup->block()} function) are fetched and rendered recursively :

  • alahup! fetches each block from the database in an xml form.

  • The xml is turned into a tree of elements.

  • This tree is rendered recursively : each element is rendered with its specific dynamic template.
