When using this method, you need to write the following code in your Block class.
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | <?php protected $variable public function __construct( \Magento\Backend\Block\Template\Context $context, \Magento\Variable\Model\Variable $variable ) { $this->variable = $variable; parent::__construct($context); } public function getCustomVarible() { $variableData = $this->variable->loadByCode('custom_variable', 'base'); return $variableData->getPlainValue(); } |
- $this->variable->loadByCode(‘custom_variable’, ‘base’) : Here first parameter is custom-variable-code and second one is store-code.
- $variableData->getPlainValue() get plain value if you can get HTML Value then use $variableData->getHtmlValue().
Get custom variable value using Object Manager
| 1 2 3 4 5 6 7 | $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $storeManager = $objectManager->get('\Magento\Store\Model\StoreManagerInterface'); $storeID = $storeManager->getStore()->getStoreId(); $objectManager->get('Magento\Variable\Model\Variable')->setStoreId($storeID)->loadByCode('custom_variable')->getHtmlValue(); $objectManager->get('Magento\Variable\Model\Variable')->setStoreId($storeID)->loadByCode('custom_variable')->getPlainValue(); |
