Let's say you load a view from a controller and that view loads another view that uses a lot of the same variables as the view that loaded it. How do get both views to share those variables? Thanks
All variables you define to a view, are passed down to views loaded within the parent one. You don't need to pass them down an other level through the second array parameter, unless you want to override a specific value.
Basically, define all variable in the 2nd parameter to the "parent" view and both views will have these variables.
For ex: you are loading view in controller:
$data["msg"] = "hi";
$this->load->view("view_file",$data);
In view_file, you are loading another view file
$this->load->view("view_file2",array("msg"=>$msg)); // here msg is extracted from first view file
In one view, i set this:
window.variable= variableToAnotherView;
windows.variable is to pass the variable globaly, so you will be able to call it in another view.

So essentially all of my views are using the header.blade.php since I am including it in my master layout. I need to pass data to the header on every single view. Is there a way to pass data just to the include rather than passing the data for the header in each view?
You don't need to do that, but you can:
All variables that are available to the parent view will be made
available to the included view. Even though the included view will
inherit all data available in the parent view, you may also pass an
array of extra data to the included view:
#include('view.name', ['some' => 'data'])
One option if you're trying to send data only to the included view is to use a view composer. They will fire even in the case of trying to prepare a view for #include
view()->composer('header', function($view) {
$view->with('data', 'some data');
});
actually the very best and faster method of sharing data to all views could be just using the
AppServiceProvider
instead of Jeff's answer you can use the share method instead of the composer method and achieve your goal faster.
Just pass the data you want in the boot method of the AppServiceProvider like following
public function boot()
{
View::share('key', 'value');
}

I have two views
index and content
The index the view that is returned to via a controller
return view();
In the index view I was able to echo out a a variable I passed it.
When cleaning the file I tried creating a second view content and including that view in from within the index
yield('content')
How can I pass a variable to content?
Try #include('content') instead.
This will include the file and all variables already available will automatically be made available in that view.
If $variable is defined in your index view, and your content view extends index, you can do this in your content view:
#extends('index', ['variable' => $variable] )
Trying to list a bunch of addresses with gmap.
Code in controller has this initialization steps:
$this->load->library('GMap');
$this->gmap->GoogleMapAPI();
$this->gmap->setMapType('map');
Was using the addMarkerByAddress in the same function as below and it was working:
$this->gmap->addMarkerByAddress($address,$ordername, $ordertitle, $tooltip, $icon_leaf);
When I try the same code in the view file it fails. I understand how to pass data to the views for display purposes (using the $data[] variable) but how do I get the gmap instance from the main file so it can be referenced in the view?
You can pass the object through
$data["gmap"] -> $this->gmap
Or you can create a Helper with the function/s you need, when you load the helper in the controller, you can access it without problem in the view.
Your view must not access controller's methods/variables/objects.
I can't understand when to use Layout's variables and when to use View's variables to get page segments on the page. Here is the picture form their Layout package tutorial ($this means the View instance everywhere):
Why Navigation, Content and Sidebar segments are got as Layout variables?
$this->layout()->nav;
But HeadTitle, HeadScript, HeadStylesheet are got straightly from View?
$this->headTitle(); // I know that this is a placeholder view helper.
// But this segment of the page logically belongs to Layout.
// and it has to be called smth like view->layout->placeholder
And why Header and Footer are from some partial method of the View but not Layout's properties?
$this->partial('header.phtml');
I've tried to change them and both ways work fine:
echo $this->nav; // I assigned navigation segment script to the View and it works;
I tried to assign Footer segment script to the Layout and it also works:
$layout->footer = $footer;
echo $this->layout()->footer; // it also works, it's displayed on the page
Any of the ways may be applied to any variable on the page. For example in Navigation segment I have a lot of variables to display and I can output them using both ways - one variable as Layout's property, another one sa View's property.
So what is the rule to use them right way? When should I use View's variables and when Layout's ones?
I agree that this isn't very clear from the documentation, and I don't think $this->layout()->nav is explained at all. A few points that might help:
$this->layout() is actually a call to the layout view helper, which returns the current instance of Zend_Layout.
Zend_Layout registers its own placeholder helper (with the key 'Zend_Layout'), and by default creates a 'content' variable in this.
the Zend_Layout class has a magic __get() method which proxies any member variable calls over to its registered placeholder container. So calling $this->layout()->content is another way of writing $this->placeholder('Zend_Layout')->content
the Zend_Layout class also has a magic __set() method that proxies stored data to the placeholder class. So $layout->footer = 'foo' is the same as calling $this->placeholder('Zend_Layout')->footer = 'foo' in the view
With that in mind:
Why Navigation, Content and Sidebar segments are got as Layout variables?
As these are accessing data stored in Zend_Layout's placeholder. You could also use $this->placeholder('Zend_Layout')->content
But HeadTitle, HeadScript, HeadStylesheet are got straightly from View?
These are view helpers.
And why Header and Footer are from some partial method of the View but not Layout's properties?
This is the standard way of accessing content from other templates.
In general, assume that using the view object is the correct way to access the data. Use the layout object/helper only if you know the data is in the layout placeholder.
The advantage of using placeholders over partials is that you can access and modify them in several different places, including in the view itself. For example say you had a sidebar which is stored in a partial. If you were to store this in the Zend_Layout placeholder instead (for example in a controller plugin), you can then override this for certain actions in the controller:
public function someAction()
{
$this->view->layout()->sidebar = 'Some other sidebar content';
}
or in the view script itself:
<?php $this->layout()->sidebar = 'Content for this page only'; ?>
I think I can't see the tree in the wood.
I'm using Zend Framework, with an layout.phtml which is rendering and partial
<?php echo $this->partial('_header.phtml') ?>
My goal is to render an form from my IndexController into the "_header.phtml" with
<?php echo $this->form; ?>
How can I pass the form to the partial view?
View partials are rendered with a clean variable scope... That is, they do not inherit view variables from the calling Zend_View instance.
There's a few options available to you here:
One, simply call:
echo $this->render('_header.phtml');
instead of using a partial. This file will have access to all your view variables, so you can just assign the form to your view in your controller, like anything else.
Another way is to explicitly pass your form as a variable to the partial, like so:
echo $this->partial('_header.phtml', array('form' => $this->form));
// $this->form inside your partial will be your form
Your other option is to either use placeholders, or layout response segments. Here's an example of placeholders:
In your _header.phtml, or layout... where ever you want the form to render:
<?php echo $this->placeholder('header'); ?>
And in your controller:
$this->view->placeholder('header')->append($form);
// I'm not sure, but you _may_ want to pass in $form->render() here.
// I can't remember if implode() (which is used in placeholders internally)
// will trigger the __toString() method of an object.
This has the added bonus of not polluting your view instance with one-off variables, like the form.
Note: I'll link to the manual pages as soon as the ZF site is back up; 1.9 launch is today, so the site's getting updated currently.
