How to Get Store Config Value in Magento 2

Hello Magento Friends,

In this blog, we will learn about getting store config value in Magento 2.

Magento stores all the configuration values in the core_config_data table. When you want to retrieve store config data, you can use the below steps.

Steps to Get Store Config Value in Magento 2:

Step 1: Create the system.xml file inside the etc folder

Path – Vendor/Extension/etc/adminhtml/system.xml     

Then add the code as follows

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
    <system>
        <section id="custom" translate="label" type="text" sortOrder="310" showInDefault="1" showInWebsite="1" showInStore="1">
            <label>Custom Settings</label>
            <group id="custom_group_id" translate="label" type="text" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
                <label>Main label</label>
                <field id="custom_field_id" translate="label" type="text" sortOrder="30" showInDefault="1" showInWebsite="1"  showInStore="1">
                    <label>Field Name</label>
                </field>
            </group>
        </section>
    </system>
</config>

Step 2: Now create Data.php file inside the Helper folder

Path – Vendor/Extension/Helper/Data.php    

Then add the below code snippet

<?php
namespace Vendor\Extension\Helper;
use Magento\Store\Model\ScopeInterface;
use Magento\Framework\App\Helper\AbstractHelper;

class Data extends AbstractHelper
{
   const XML_CONFIG_PATH = 'custom/custom_group_id/custom_field_id';
   
   public function getConfig()
    {
        $configValue = $this->scopeConfig->getValue(self::XML_CONFIG_PATH,ScopeInterface::SCOPE_STORE);
        return $configValue;
    }
}

Note – You can inject the helper class anywhere and use the getConfig() function to get the config value.
