Magento2: get values to databse

I’m trying to get values from the popup model of radio buttons into the database and I’m not getting that, what am I doing wrong?

BLOCK FILE

<?php

namespace vendorThreeYearOrdersBlock;

      /**

     */
    const XML_THREE_YEAR_ORDERS_BLOCK_ID = 'ThreeYearOrders/general/block_id';

    /**
     * @var ScopeConfig
     */
    protected $_scopeConfig;

    /**
     * Popup constructor.
     *
     * @param ScopeConfigInterface $scopeConfig
     */
    public function __construct(
        MagentoFrameworkViewElementTemplateContext $context,
        MagentoFrameworkAppConfigScopeConfigInterface $scopeConfig,
        Session $customerSession
    ) {
        parent::__construct($context);
        $this->_scopeConfig = $scopeConfig;
        $this->_customerSession = $customerSession;
    }

    /**
     * Get Popup Config
     *
     * @return array|mixed
     */
    public function getThreeYearOdersBlockId()
    {
        return $this->_scopeConfig->getValue(self::XML_THREE_YEAR_ORDERS_BLOCK_ID, MagentoStoreModelScopeInterface::SCOPE_STORE);
    }
    /**
     * Check if customer is logged in
     *
     * @return bool
     */

    public function isLoggedIn()
    {
        return $this->_customerSession->isLoggedIn();
    }
    public function getFormAction()
    {
        return $this->getUrl('vendor_threeyearorders/Index/Action', ['_secure' => true]);
    }
