I want to check that a url/id is valid in a before render function and was
wondering how to go about it.
So if a user types in an address site/posts/some_id_here
it will check the "some_id_here" against the db to see if it exists
i have
function beforeRender()
{
if ($this->Post->validURL($post_id) == false) {
$this->redirect(array('controller' => 'posts', 'action' =>
'index'));
}
}
but i get $post_id is undefined variable
How do I pass the $post_id to a before function? Much easier to verify it in
1 place than have to run the verify function in every action in the
controller.
