magento 2 module register event observer

Question

Is there a way to do some action at module registration/installation?

It can be through event observer or through migration.

I want to call a function to get some values and store them in core_config_data during installation.

Thanks.

Answer 1

You can use InstallData.php to store value in core_config_data during installation

use below code for example :

$configdata = [
                'scope' => DEFINE_YOUR_SCOPE
                'scope_id' => 0,
                'path' => DEFINE_YOUR_PATH
                'value' => YOUR_VALUE,
            ];
 $setup->getConnection()->insertOnDuplicate($setup->getTable('core_config_data'), $configdata, ['value']);

Answer 2

Try to save config values via config.xml

First Method:

app/code/VendorName/ModuleName/etc/config.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">
    <default>
        <sectionName>
            <groupName>
                <fieldName>add value here</fieldName>
            </groupName>
        </sectionName>
    </default>
</config>

For eg.

<default>
    <payment>
        <checkmo>
            <active>1</active>
            <order_status>pending</order_status>
            <title>Check / Money order</title>
        </checkmo>
    </payment>
</default>

Second Method:

<?php
namespace VendorName\ModuleName\Setup;

use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

/**
 * @codeCoverageIgnore
 * @SuppressWarnings(PHPMD.CouplingBetweenObjects)
 */
class InstallData implements InstallDataInterface
{
   public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
   {

        $data = [
            'scope' => 'default',
            'scope_id' => 0,
            'path' => "{section-name}/{group-name}/{field-name}",
            'value' => "Value",
        ];
        $setup->getConnection()
            ->insertOnDuplicate($setup->getTable('core_config_data'), $data, ['value']);
    }
}

After run below commands:

• php bin/magento setup:upgrade
• php bin/magento setup:di:compile
• php bin/magento cache:clean
