Magento – How to use custom variables in Magento 2

admin-panelcustom-variablemagento-2.1.3

I have seen email templates to use built-in custom variables. Can someone explain how to use System -> Other Settings -> Custom Variables? For example category count, which will show in frontend.

From what I have used custom variable, it is only for passing admin manageable value to your code, you can access it as follows;

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$model = $objectManager->get('Magento\Variable\Model\Variable')->loadByCode('custom-variable-code');
$plain_value = $model->getPlainValue();

EDIT:

As asked by @Jonas de Herdt if you want to get store specific value for the variable you just need to pass the store code along with the custom variable code as follows;

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$model = $objectManager->get('Magento\Variable\Model\Variable')->loadByCode('custom-variable-code', 'store-code');
$plain_value = $model->getPlainValue();

Reminder that you should not use objectmanager directly in your code

Magento 1.9 – Using Custom Variables in Category Description

The easiest way to do it, is to use the same template processor for category description as it is used for the cms blocks and pages content. The one from the widget module.
For this you need an extension. Let's call it StackExchange_Catalog.
You will need the following files.

app/etc/modules/StackExchange_Catalog.xml - the declaration file

<?xml version="1.0"?>
<config>
    <modules>
        <StackExchange_Catalog>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Catalog />
                <Mage_Cms />
                <Mage_Widget />
            </depends>
        </StackExchange_Catalog>
    </modules>
</config>

app/code/local/StackExchange/Catalog/etc/config.xml - the configuration file

<?xml version="1.0"?>
<config>
    <global>
        <catalog>
             <content>
                <tempate_filter>widget/template_filter</tempate_filter>
            </content>
        </catalog>
    </global>
</config>

clear the cache and try again.

Email Templates – How to Get Custom Variable into an Email Template

There's a simple way you can do this. Creating a custom variable for the email can be too much time consuming, so the easiest way to get this result would be using a .phtml file on your transnational email.

Add this to your email HTML:

{{block type='core/template' area='frontend' template='email/custom/mynote.phtml' order=$order}}

Create a file path/to/magento/app/design/frontend/base/default/template/email/custom/mynote.phtml

Now in this file you could do something like this:

   $pointsBalance = Mage::getModel('rewards/customer')->load($customerId)->getUsablePoints();
 echo $pointsBalance[1];

Done :)
