Constant return null (2.2.4)

Question

I'm trying to define constant in an helper of my module :

here's my Data.php :

class Data extends AbstractHelper
{
    const base = "my/url";   

    public function getBase(){
        return $this->scopeConfig->getValue(
            self::base,
            \Magento\Store\Model\ScopeInterface::SCOPE_STORE
        );
    }


} 

And my block, I create a function to get my constant :

public function getBaseAPIT(){
   return $this->_helper->getBase();
}

But the result of getBaseAPIT() is null. Where am I wrong ?

PS : to do this, I've follow that https://www.maximehuran.fr/creer-un-helper-sous-magento-2/

Answer 1

For set to constant as per your logic need my/url value in database: add like below example:

      INSERT INTO `core_config_data` (`config_id`, `scope`, `scope_id`, 
      `path`, `value`) VALUES ('53069', 'default', '0', 'my/url', 
    'www.example.com');

then you will get www.example.com by calling this function getBaseAPIT() }
