Re: Using $this->set in view doesn't set the var
I'm talking to correct this sentence (from
http://book.cakephp.org/view/1086/set):
In your view file you can do
$this->set('activeMenuButton', 'posts');
*Then in your layout the $activeMenuButton variable will be available and
contain the value 'posts'.*
because it should say that the var will be available through
$this->viewVars, not as a local variable. That's why I'm confused, I never
really thought if it was possible or not.

Re: Using $this->set in view doesn't set the var
It totally does, it does not however, come with a time-machine. Once you understand the constraints of time and space, and the fact that you cannot inject local variables into a different execution stack frame in PHP it works exactly the same. Having to update the cake docs about these constraints seems a bit condescending to me. -Mark On Sep 13, 6:36 am, Xoubaman wrote: > I think doc needs a correction then, as Var::set doesn't work exactly > analogous to Controller::set. -- Our newest site for the community: CakePHP Video Tutorials http://tv.cakephp.org Check out the new CakePHP Questions site http://ask.cakephp.org and help others with their CakePHP related questions.

Re: Using $this->set in view doesn't set the var
Keep in mind - when you are doing $this->set from an element: You aren't calling View::set - you are calling Element::set. Why would you expect that to behave as if it was an instance of the View class when it isn't? Also, the two pass rendering of CakePHP means that in order for what you propose to work you would need a 3rd pass through the stack of set variables and rendered elements before parsing the combined view output. This isn't how Cake works and struggling this much to force the framework to do something it isn't meant to is going to simply be a waste of your time, either now - getting it to work - or later when you have to support it.

Re: Using $this->set in view doesn't set the var
Yeah you can't use set() to magically push a variable into the layout scope from an element. That's simply impossible in PHP. If you have an element in your layout that uses View::set() you should either get it from $this->viewVars or use $this->getVar(). To access it later in the layout. -Mark On Sep 10, 3:37 am, WebbedIT wrote: > Yip, the api does state "Allows a template or element to set a > variable that will be available in a layout or other element", but > maybe this is when the element is being called from the view not the > layout? > > People are not really supposed to read your layout though, that is set > and should rarely be changed.

Re: Using $this->set in view doesn't set the var
Yip, the api does state "Allows a template or element to set a variable that will be available in a layout or other element", but maybe this is when the element is being called from the view not the layout? People are not really supposed to read your layout though, that is set and should rarely be changed. Plus it's a lot cleaner to only be echoing $content_for_layout, $menu_for_layout etc. than it is to be calling all view data from the layout. However, I am not experienced enough with MVC to give a compelling argument against it, I just know when something rubs against Cake's conventions then it;s normally not a good idea. HTH, Paul.

Re: Using $this->set in view doesn't set the var
Can you show me the documentation that says you can set variables from an element to be used in the layout? If something is wrongly documented the core team will gladly correct it, but remember an element is not a view ... whilst closely related to views, an element is not meant to interact with the layout. What may seem a simpler approach to you does not neccessarily equal a cleaner approach. You're changing the request and response process from: - Controller (recieves request) - Model (requests and processes relevant data) - Controller (passes data to view) - View (constructs view - should be doing minimal data processing) - View elements (passing data sent from model to view) - Layout (builds layout around view - should be doing even less data processing than view) - Layout elements (passing data sent from view to layout) to: - Controller (recieves request) - Model (requests and processes relevant data) - Controller (passes data to view) - View (bypass, as not building view) - View elements (bypass, as not building view) - Layout (builds layout around nothing as no view passed) - Loader elements (now you request and try to display all your data) Essentially, you are using elements in a non-conventional manner, then saying the documentation is wrong!

I know it's possible to accomplish it like you said -and thanks for your answers and efforts to help, by the way-, but the basis of my question is why a documented view method it's not working as expected.

Re: Using $this->set in view doesn't set the var
So you're wanting to pass a fully rendered element to the layout as a
variable? Much in the same way we pass a fully rendered view to the
layout as $content_for_layout.
When building dynamic sidebars I created an array in the controller,
including the data and element name for each position in the sideber,
which I loop through in the view calling $this->element($element,
$dataArray());
You could do the same or if you must have things in the layout then
you would need to pass the array from the view to the layout and look
through it there calling the elements.
Either way the data is already available at the view and/or layout as
it is from there you call $this->element() and pass it the data.

Re: Using $this->set in view doesn't set the var
My concrete case:
In a CMS-like app, I have modules that can be attached to layout positions.
Layout positions are vars echoed in each layout. So, I use a loader element,
placed at the top of each layout, that should load each position var with
his own output.
Layout example:
elements('loader'); ?>
...
...
...
Loader behavior:
foreach ($modules as $position => $attached_modules) {
foreach ($attached_modules as $model) {
$output[$positions] .= $this->element($model);
}
$this->set($output);
}
Something like that. Code is not that way exactly, but I think it's enough
to get the idea. The problem is that the $this->set at the bottom of loader
element sets the var in viewVars attribute, but doesn't populate the vars to
be accessed straight in the layout (as said in the doc, here:
http://book.cakephp.org/view/1086/set)
I know I could call each element in each position, but it will mess up the
layout code and difficult creating or editing layouts, instead the elegant
echo $position ^^

Re: Using $this->set in view doesn't set the var
Still don't get it, maybe you need to show us your real world example of how the element is communicating with the layout and other elements. That way we can understand and someone can solve or offer an alternative solution. At the initial page load, all elements should have their data passed to them via the main controller action or their own requestAction, I would fire separate ajax requests for other elements if they are to be updated due to a DOM change. I'm not sure the documentation does specifically say that elements can set vars, did you read that from here? http://book.cakephp.org/view/1081/Elements You can set variables from the controller (to the view) and the view (to the layout) but elements are not supposed to go to anything else, they are the end of the line.

Re: Using $this->set in view doesn't set the var
Me neither, until now :) On the topic of setting vars in an element, regardless of it being wrong or not, the point is that it's possible. At least the doc says so, but it's not working for me (the Var::set() method). You may have an element that gets data from requestAction and, depending on the returned values, subsecuent layout contents will need different vars defined. -- Our newest site for the community: CakePHP Video Tutorials http://tv.cakephp.org Check out the new CakePHP Questions site http://ask.cakephp.org and help others with their CakePHP related questions.

Re: Using $this->set in view doesn't set the var
I have never accessed anything from $this->viewVars, once set a
variable is accessed from $variableName.
Something sounds wrong with your methodology If you're setting
variables in an element to be used in other elements/parts of the
layout. An element by definition is a contained collection of view
code, not sure why it should interact during a page load with other
elements.

Using $this->set in view doesn't set the var
I have an element in layout that generates some variables I want to use
following parts of layout and view. As read in doc
(http://book.cakephp.org/view/1086/set), using $this->set('varname', $value)
will result in $varname available in the layout, but I'm getting a Undefined
variable notice.
debug($this->viewVars) before the var-generating element throws something
like:
Array
(
[title_for_layout] => Awesome web
[controller_set_var1] => lol
[controller_set_var2] => foo
)
Then, the element is echoed, and debugging $this->viewVars shows:
Array
(
[title_for_layout] => Awesome web
[controller_set_var1] => lol
[controller_set_var1] => lol
[element_set_var] => gotcha!
)
But $element_set_var stills undefined.
Is this the normal behavior? Should I take $element_set_var manually from
$this->viewVars?
