render a view from another controller, yii

Question

The controller:

controllers |-FooController.php |-BarController.php 

The views:

view |-foo| |    |-index.php |    |-error.php | |-bar|      |-index.php 

How to render the error.php view with an action of the bar controller? I have tried:

$this->render('foo/error'); 

But it doesn't work.

Answer 1

try this

$this->render('//foo/error'); 

Answer 2

If you don't echo it, you will get a blank page. The correct way is

<?=    $this->render('//foo/error'); ?> 

or

<?php      echo $this->render('//foo/error'); ?>  

This also works for Yii2
