save data from a module in database if save config button is click in admin configuration. Basically I want to disabled a module if disabled from admin. Actually disable functionality is not working. So I trying disabled module pro grammatically I have created a controller with update query but this works when I hit the controller in front end. Basically My query disable module from general but my query will disable from advance/advance.

Path of controller - Vendor/Module/Controller/index/index.php

function in controller that I trying to update :-

public function execute()

{

    $objectManager = MagentoFrameworkAppObjectManager::getInstance(); // Instance of object manager

        $resource = $objectManager->get('MagentoFrameworkAppResourceConnection');

        $connection = $resource->getConnection();

        $tableName = $resource->getTableName('core_config_data'); 

   echo $isEnabled = $this->helperData->isEnable();



   if ($isEnabled==1) {

        //gives table name with prefix



        //Select Data from table

        echo $sql = "Update " . $tableName . " Set value = 0 where path ='advanced/modules_disable_output/Vendor_Module'";

        $connection->query($sql); 



        }



        //return $result->setData($methods);



    else {

        echo $sql = "Update " . $tableName . " Set value = 1 where path ='advanced/modules_disable_output/Vendor_Module'";

        $connection->query($sql); 



        }

}

You can achieve what you want to do by either using observer or plugin as follows ;

Following event are fire after System->configuration Save.

admin_system_config_changed_section_{$section} -> here $section is 'general' etc.

Here is an example for 'admin_system_config_changed_section_general' event.

etc/events.xml

<?xml version="1.0" encoding="UTF-8"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">

    <event name="admin_system_config_changed_section_general">

        <observer name="custom_admin_system_config_changed_section_general" instance="[Vendor][Module]ObserverConfigObserver"/>

    </event>

</config>

and observer class is "[Vendor][Module]ObserverConfigObserver"

namespace [Vendor][Module]Observer;



use MagentoFrameworkEventObserverInterface;

use MagentoFrameworkEventObserver as EventObserver;

use PsrLogLoggerInterface as Logger;



class ConfigObserver implements ObserverInterface

{

    /**

     * @var Logger

     */

    protected $logger;



    /**

     * @param Logger $logger

     */

    public function __construct(

        Logger $logger

    ) {

        $this->logger = $logger;

    }



    public function execute(EventObserver $observer)

    {

        //$this->logger->info($observer->getWebsite());

        //$this->logger->info($observer->getStore());

    }

}

You can do this same thing using plugin.
Create di.xml "etc/di.xml"

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <type name="MagentoConfigModelConfig">

        <plugin name="admin_system_config_save_plugin" type="[Vendor][Module]PluginConfigPlugin" sortOrder="1"/>

    </type>

</config>

And Plugin class '[Vendor][Module]/Plugin/ConfigPlugin.php'

namespace [Vendor][Module]Plugin;





class ConfigPlugin

{

    public function aroundSave(

        MagentoConfigModelConfig $subject,

        Closure $proceed

    ) {

        // your custom logic

        return $proceed();

    }

}
