Is there any class/file from module-config module that can be useful whether single_store_mode value has been changed from yes to no or vice-versa.

Have checked admin_config related events but these are not useful as these are calling after save.

EDIT:

I want to have before Save as well as after Save value so i can compare whether value has been changed or not?

Tried to implement two approaches but unfortunately it's not working.

  1. By applying source_model on the general/single_store_mode/enabled in custom module's system.xml

  2. Using beforeSave() plugin on Magento\Config\Model\Config

Inject \Magento\Framework\App\Config\ScopeConfigInterface and use $this->scopeConfig->getValue('general/single_store_mode/enabled'); to read the value.

Or you can use then @Philipp Sander solution in a more elegant way

app/code/Vendor/Module/Helper/Data.php

namespace Vendor\Module\Helper;

use Magento\Framework\App\Config\ScopeConfigInterface;


class Data extends \Magento\Framework\App\Helper\AbstractHelper

{

    protected $_scopeConfig;

    public function __construct(
        ScopeConfigInterface $scopeConfig
    ) {
        $this->_scopeConfig = $scopeConfig;
    }


    /**
    * Use scope magento config
    *
    * @param string $config_path
    */

    public function getStoreConfig($config_path)
    {
        return $this->_scopeConfig->getValue(
            $config_path,
            \Magento\Store\Model\ScopeInterface::SCOPE_STORE
        );
    }
}

Then you inject that helper in your constructor

protected $_helper;

public function __construct(
    ...
    \Vendor\Module\Helper\Data $helper 
) {
    ...
    $this->_helper = $helper;
}

 public function execute() {
    $singleStoreMode = $this->_helper->getStoreConfig('general/single_store_mode/enabled');
}

Note : Don't forget to generate the new DI classes :

php bin/magento setup:di:compile

  • this is exactly what I said. How is it more elegant to wrap it in a helper? – Philipp Sander Dec 3 '19 at 12:46
  • @Philipp Sander it's more elegant to use getStoreConfig() function and use it in other files if needed, it also good what you did, that's why I gave you +1 – PЯINCƏ Dec 3 '19 at 13:55
  • when extending a class, you should make sure that the parent constructor is being called. and if you take a look at abstracthelper you will see that it already has a scopeconfig. so no need to inject it again. what excatly is you benefit of having that helper? why not inject scopeconfig into your service directly? – Philipp Sander Dec 3 '19 at 14:46
