#5935: Helpers should always be addressed by $this->Helper->func() instead of
$helper->func()

Reporter: euromark | Type: Enhancement

Version: 1.2 Final | Severity: Normal

--------------------------+-------------------------------------------------
Helpers that are included via $helpers = array(...) in AppController
should always be addressed by $this->Helper->func() instead of
$helper->func()
in the view.

This prevents multiple conflicts with either already defined $vars in the
view itself
or with baked views via console, which you can as well set up manually now
due to the naming conflict..

problem a:[[BR]]
if you add a new (lets call it "poll_helper.php") helper afterwards in
order to get some polls to the index() method (and view "index.ctp), you
might accidently crash the other views without knowing it, as the $poll
could have been used there as a normal variable.
[[BR]]
[[BR]]
problem b:[[BR]]
if you bake a model "poll" from the DB table "polls" and the controller
"polls" with its views, the console baking will bake the index view like
the following:
{{{
...
echo $poll['Poll']['modified'];
...
}}}
which conflicts again with our $poll helper[[BR]]
this would not be happening if we would address the helpers differently.
[[BR]]
[[BR]]
its cleaner - and both problems (and probably some others as well) would
be solved with this approach.
[[BR]]
Besides the fact that inside other helpers this is already done this way:
{{{
// inside Poll Helper
$this->Html->doSomething();
}}}
[[BR]]
[[BR]]
if you dont like that one (for whatever reason), you could use $nameHelper
(in my example $pollHelper) as variable for all helpers with the filename
"name_helper.php".
