In this post I am going to explain how to Set Default Values for System Configuration Fields in Magento 2.
First we will make one “system.xml” file at below path.
Path: app/code/<vendor>/<module>/etc/adminhtml/system.xml
<?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>
<tab id="ht" translate="label" sortOrder="999999">
<label>HT</label>
</tab>
<section id="mymodulesection" translate="label" type="text" sortOrder="30" showInDefault="1" showInWebsite="1" showInStore="1">
<class>separator-top</class>
<label>My Module</label>
<tab>ht</tab>
<resource>Magento_Config::config_admin</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="5" showInDefault="1" showInWebsite="1" showInStore="1">
<label>Enabled</label>
<source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
</field>
<field id="welcome_text" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
<label>Welcome Text</label>
</field>
</group>
</section>
</system>
</config>Now, we need to set default values for above system config fields.
For that add one file “config.xml” at below path.
Path: app/code/<vendor>/<module>/etc/config.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../Store/etc/config.xsd">
<default>
<mymodulesection>
<general>
<enabled>1</enabled>
<welcome_text>Welcome</welcome_text>
</general>
</mymodulesection>
</default>
</config>The path of the field is “section/grounp/field”.
Here our section is “mymodulesection”, group is “general” and fields are “enabled” and “welcome_text”.
This code will make default system config value when you install module.
