Magento 2 – Get Custom Variables

You may have recently wondered how to get a specific custom variable in Magento 2.

The old way of doing this in Magento 1 looked similar to this.

Mage::getModel('core/variable')->loadByCode('my_custom_variable')->getValue('plain');

In Magento 2 we need to add the correct class to our constructor.

protected $_variable;

public function __construct(
    \Magento\Variable\Model\Variable $variable
) {
    $this->_variable = $variable;
}

Then in our custom function, we can get the values of our custom variable like so.

$vendorExceptionList = $this->_variable->loadByCode('my_custom_variable')->getValue('plain');
$vendorExclusions = explode(', ', $vendorExceptionList);

You can also load a custom variable by its ID.

$this->_variable->setStoreId($storeId)->load($variableId);
