How to pass param from controller to layout in YII2

Question

I want to send a parameter from controller to layout (i.e. main.php). But I am not able to get the param in main.php

I tried:

Controller Code:

$this->render('index',array('param' => $paramValue));

And this is how i was trying to get this in layout ie. main.php

$this->param (as in yii 1)
$param

But i am not able to get param value in layout. Can anyone tell me how to do this?

http://www.yiiframework.com/doc-2.0/guide-structure-views.html#creating-layouts you shoulld reread manual and look at `->beginContent()` method. — user1954544, Jan 20 '15 at 06:50
You can use $this->context to do this. See my answer: https://stackoverflow.com/a/60463356/884177 — smohadjer, Feb 29 '20 at 08:42

yii\base\View has special $params property.

For example it's used for building breadcrumbs in default generated CRUD code templates with Gii.

You can set it like this before rendering:

use Yii;

Yii::$app->view->params['customParam'] = 'customValue';

Inside a controller you can set it like this:

$this->view->params['customParam'] = 'customValue';

Then it will be available in views (including main layout):

/* @var $this yii\web\View */

echo $this->params['customParam'];

You can also find it in official guide.

I would like to suggest you some steps for this problem.

pass parameter to view file
Set parameter to view parameter

Check For parameter and If exist then use it.

//in controller method
$this->render("view-file-name",["paramName" => "some parameter"]);

//in view file for eg: index.php
//i'm passing paremeter sent form controller's action to view params.
$this->params["paramFromViewFile"] = $paramName; //here $paramName is the parameter we sent from controller's method

//access parameter sent from view file
if($this->params && !empty($this->params["paramFromViewFile"]))
{
     echo $this->params["paramFromViewFile"];  
}

In Yii2 you can access your controller object from a view using $this->context for example if in your controller you set a parameter like this:

public $title = 'My custom title';

Then in your layout you can read it like this:

$this->context->title

It is explained in Yii documentation in section: Accessing Data in Views

Thats because you are rendering index.php view, not the main.php one.

And $param this is how you get it in 1.1 version.

UPD: If you want a param in your main.php layout declare it in your Controller class, and then you will be able to get it $this->param this way.

UPD2: Looks like in 2.0 version you need to declare param in a yii\web\View class. And access it via Yii::$app->view->param.

main.php is main layout file. We never need to render that file – Amit Kumar Jan 20 '15 at 06:27

directly calling $param u should get the value, try

in controller declare a $param,
public $param = '';

then in the acction do
$param='haha';

in layout
echo $this->param;

I had a same problem, I resolve that in:

In my Controller par exemple, I do that

$this->view->params['typeUser'] = 'Internaut';
in my View

$this->params['typeUser'] or echo $this->params['typeUser']
