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.

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']);
  • Thanks @Hariharan. I want to also do some action (call an api using this config values as parameters) during installation. Can you help?

  • Not sure. you can try to create a new function to call api for testing in InstallData.php and call into install function

Try to save config values via config.xml

First Method:


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

For eg.

            <title>Check / Money order</title>

Second Method:

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)

        $data = [
            'scope' => 'default',
            'scope_id' => 0,
            'path' => "{section-name}/{group-name}/{field-name}",
            'value' => "Value",
            ->insertOnDuplicate($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
  • Thanks @Abdul. The idea is to collect some store information and store them into the config data and use them as a parameter to call an api during module installation. Is this possilbe?
