Magento 2 - How to list websites on frontend

Question

What's the best method to get specific data in Magento 2, i.e. to list all the websites in the CMS? In Magento 1 I'd use

Mage::app()->getWebsites()

But that doesn't work in Mag2 anymore. I do see code like this:

$this->storeManager = $storeManager;
$id = $this->storeManager->getStore()->getId();

Which I guess would be a fair starting point, but whenever I call this code in the frontend, I get Notice: Undefined variable: storeManager errors. So appareantly this isn't the way to call that storeManager. My question is; what is the right way?

Answer 1

To get the list of all websites, you indeed need to use the storeManager, which is a native variable of every block extending \Magento\Framework\View\Element\Template:

In your block class, you either directly do:

$this->_storeManager->getWebsites();

Or if you need to get the websites in a template assigned to your block you can declare a function:

public function getWebsites() {
    return $this->_storeManager->getWebsites();
}

Then in your template you can do:

$block->getWebsites();

Note that if you want to get the websites in a controller or any other non block class, you will have to use dependency injection in the constructor first to be able to use the storeManager code above:

protected $_storeManager;

public function __construct(\Magento\Store\Model\StoreManagerInterface $storeManager)
{
    $this->_storeManager = $storeManager;
}
