| + | ===== Gathering of data ===== | ||
| + | This is not a requirement, but good advice: avoid passing PHPTAL object (or template abstraction wrapper) around your entire program. MVC programs should be independent of their views (mental exercise: would your application break if there was no view?). | ||
| + | |||
| + | Instead of setting variables directly on PHPTAL object, make your methods //return// all required information. You can also pass helper objects to PHPTAL which will load data on demand. | ||
| + | |||
| + | <code php><?php | ||
| + | $result_array = execute_my_page(); | ||
| + | $result_array['logged_in_user'] = find_logged_in_user(); | ||
| + | $result_array['sidebar'] = new SidebarHelper(); | ||
| + | |||
| + | $phptal = new PHPTAL($page_template); // create PHPTAL object *after* getting data | ||
| + | |||
| + | foreach($result_array as $k => $v) $phptal->set($k,$v);</code> | ||
