This tutorial includes the knowledge of get value of system configuration, how to add your custom configurations in system configurations and also how to retrieve their values too. Configuration values are saved in core_config_data table , in this table you can see the path and value of your configuration settings. So let’s start with our example.
Create system.xml
First step is create system.xml in following directory.
QaisarSatti/HelloWorld/etc/adminhtml/
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
<system>
<tab id="qaisarsatti_helloworld" translate="label" sortOrder="200">
<label>QaisarSatti HelloWorld</label>
</tab>
<section id="helloworld" translate="label" type="text" sortOrder="100" showInDefault="1" showInWebsite="1" showInStore="1">
<label>HelloWorld COnfiguration</label>
<tab>qaisarsatti_helloworld</tab>
<resource>qaisarsatti_helloworld::config</resource>
<group id="general" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
<label>General</label>
<field id="enabled" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
<label>Enabeld </label>
<source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
</field>
<field id="title" translate="label" type="text" sortOrder="5" showInDefault="1" showInWebsite="1" showInStore="1">
<label>Title</label>
</field>
</group>
</section>
</system>
</config>
Retrieve System configuration
For retrieving the values we create the helper file Data.php in following directory
QaisarSatti/HelloWorld/Helper/Data.php
First thing you need to know for retrieving the values in is combination of sestionid/groupid/fieldid to get value.
namespace QaisarSatti\HelloWorld\Helper;
class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
const HELLOWORLD_MODULE_ENABLED = 'helloworld/general/enabled';
const HELLOWORLD_LABEL = 'helloworld/general/title';
public function __construct(
\Magento\Framework\App\Helper\Context $context
) {
parent::__construct($context);
}
public function getEnabled()
{
return $this->scopeConfig->getValue(
self::HELLOWORLD_MODULE_ENABLED,
\Magento\Store\Model\ScopeInterface::SCOPE_STORE
);
}
public function getLabel()
{
return$this->scopeConfig->getValue(
self::HELLOWORLD_LABEL,
\Magento\Store\Model\ScopeInterface::SCOPE_STORE
);
}
}
Now: Following you can retrieve system configuration.
