I have added some custom fields to the admin->configurations->sales->payment section using the following method.

created config.xml inside etc folder of my module dir.

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">
            <name>Product Specific Payment</name>

Then created system.xml in adminhtml folder.

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
    <section id="payment">
        <group id="productspecific" translate="label" type="text" sortOrder="500" showInDefault="1" showInWebsite="1" showInStore="1">
            <label>Productspecific Payment Configuration</label>
            <field id="active" translate="label" type="select" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="0">
            <field id="title" translate="label" type="text" sortOrder="20" showInDefault="1" showInWebsite="1" showInStore="1">
            <field id="name" translate="label" type="text" sortOrder="30" showInDefault="1" showInWebsite="1" showInStore="1">
            <field id="allowed_shippings" translate="label" type="multiselect" sortOrder="40" showInDefault="1" showInWebsite="1" showInStore="0">
                <label>Allowed Payment Methods</label>
            <field id="highes_amount" translate="label" type="select" sortOrder="50" showInDefault="1" showInWebsite="1" showInStore="0">
                <label>Fallback Payment</label>

now it is working fine. but How I can retrieve these saved values in product adding a page or any other files?

especialy inside a Model.

  • what should i use instead of SCOPE_STORES? – Sanjun Dev Sep 17 at 12:04
  • You can use the SCOPE_TYPE_DEFAULT and SCOPE_STORES in the $storeScope. SCOPE_TYPE_DEFAULT for getting default view configuration while SCOPE_STORES is for getting store views settings. Check my answer for the same. – Sumit Sep 17 at 12:07

You can get the value of the system.xml fields in your block, model, controller by adding the below code in them.

protected $_scopeConfig;

public function __construct( 
    \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
    $this->_scopeConfig = $scopeConfig;

public function getYourValue() {
    $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORES;
    return $this->_scopeConfig->getValue("section_id/group_id/field_id", $storeScope); //where section_id, group_id and field_id defined in your system.xml file

You can use the SCOPE_TYPE_DEFAULT and SCOPE_STORES in the $storeScope. SCOPE_TYPE_DEFAULT is for getting default view configuration setting while SCOPE_STORES is for getting store views configuration setting.

Hope it helps!!!


Hope below code will help you :

namespace Company\Module\Helper;

use Magento\Framework\App\Helper\AbstractHelper;
use Magento\Store\Model\ScopeInterface;

class Data extends AbstractHelper

    const XML_PATH_HELLOWORLD = 'helloworld/';

    public function getConfigValue($field, $storeId = null)
        return $this->scopeConfig->getValue(
            $field, ScopeInterface::SCOPE_STORE, $storeId

    public function getGeneralConfig($code, $storeId = null)

        return $this->getConfigValue(self::XML_PATH_HELLOWORLD .'general/'. $code, $storeId);


Try this one:

public function __construct(
    \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
) {

And get the config value:

public function getTitle()
    $title = $this->getConfigData('title');
    return $title;
