Re: Modification of a helper method?

Well, you could create a helper that doesn't modify the helper method,
but simply uses it.

E.g. in your views:
echo $myHelper->link('delete', $id); // generate a delete link for $id
for the active controller
echo $myHelper->link('edit', $id); // generate an edit link for $id
for the active controller
echo $myHelper->link('delete', $id, 'posts'); // generate a delete
link to another controller

Then in your helper, you just need to check the value of a view
variable and either generate the link or not generate it based on
that:
function link($action, $id = null, $controller = null) {
... // set default $id and $controller
$link = '';
$view =& ClassRegistry::getObject('view');
if ($view->viewVars['hasPrivilege']) { // check the controller-set
variable
$link = ... // generate the link
}
return $link;
}

Then in your controller you just need to set $hasPrivilege in the
view.
