Background: i am trying to build a little database-driven 2-level
menu system that checks authorization to access menu pages and actions
*before* they are displayed. If you are not authorized to use the
"budgets" table in any way, you won't be presented with a "budgets"
menus option (I am using Authake for the auth function)
To stick with MVC convention, I figured I should put as much of the DB
access and auth in my "menus" controller. I would use find() with
some complex conditions to extract only the set of menus that I wanted
a user to get. I had problems with my conditions in find() and I
concluded I didn't understand it well enough -- maybe a fundamental
misunderstanding about variable scope and what could be sent in to a
query via find().
So I backed up and added
echo "<pre>"; print_r($this->viewVars);echo "</pre>";?>
to my default.ctp so I could see what vars were being set in my
controller:
I am using routes and using URL comparison to select menu records from
the database. I can set this in the controller:
$this->set('current_uri', $_SERVER[REQUEST_URI]);
The idea is to use URL to set parent menu and then query all parent
+child menu records.
But when I went to use $current_uri it in a find(all, [conditions])
the find simply failed So I did another test. I can set:
$this->set('menu_link', "/budgets" );
but when I subsequently try to do this set in the next line in the
controller:
$this->set('menu_name', $menu_link );
I see menu_name in viewVars, but it has no value. I get the same no-
value result if I use:
$this->set('menu_name', $this->menu_link );
All this tells me that there is something really basic this perpetual
n00b doesn't understand about scope of vars in viewVars and/or how
they can be compared or set in the controller.
Any thumps with the clue stick appreciated.
