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.

Solution 1

try this

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

Solution 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
