I would recommend another way. gwoo's solution means a request to the
db every time(!) the navigation is shown. IMHO too much db-action. I
would create a function in the controls controller like
function updateNavigation() {
$entries = $this->Control->findAll();
$string = '<ul>';
foreach ($entries as $key => $value) {
$string .= "<li><?php echo \$html->link('Link text', '/url/to/
page/') ?></li>\r\n";
}
$string = '</ul>';
// rewriting the thtml-file of the navigation-element.
$fp =
fopen(ROOT.DS.APP_DIR.DS.'views'.DS.'elements'.DS.'navigation.thtml',
'r+');
ftruncate($fp, 0);
fputs($fp, $string);
fclose($fp);
}
Call this function with every create and update (e.g. in add(),
edit()) and it rewrites your navigation element with the newest data.
so most of the request on the navigation do not need a db request.
I use this in several apps and it works pretty good and saves
ressources of your db.
