I want to modify a setting, which I know how to find and change in the Magento Admin, - but I want to modify it in the config.php file. Which way can i find out the configuration path / syntax within the config.php file for that specific setting?

Example I want to set the cookie restriction mode to Yes via config.php. http://docs.magento.com/m2/ee/user_guide/stores/compliance-cookie-restriction-mode.html describes how to change the setting in the Magento Admin.

It seems to be possible to get the path from /src/vendor/magento/module-cookie/etc/config.xml:

<?xml version="1.0"?>
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">

... which could translate into ...

'system' => 
  array (
    'default' => 
      array ( 
        'web' =>
           array (
             'cookie' =>
                array (
                  'cookie_lifetime' => '3600',
                  'cookie_restriction' => '1'

... but that seems a bit complicated to me for everyday usage (1. find the right module, 2. investigate source code, 3. translate xml to config.php format). Is there an easier way?

  • Have you checked this with config:dump command? Sep 26, 2018 at 4:58
  • I'm a bit worried about destroying my config with that one, @Ramkishan...

  • It actually was a great hint! - I took a backup of env.php and config.php first, then run bin/magento app:config:dump. The script updated env.php and config.php for me; I stored the two updated files in a safe place and restored the backup, so that the environment would run the same way as before. I then was able to find and copy the configurations I needed in the stored config.php file. Thank you, @Ramkishan!

  • @Ramkishan, do you want to add it as an answer, so that I can mark it as "correct"?

You can do this using app:config:dump command. This will generate system specific, configuration specific, sensitive configuration settings in config.php and env.php files. Then using app:config:import command you can update your configuration once you update these files.

I hope it'll work for you.
