Set value to specific custom theme setting

Question

I noticed that I can get a specific theme setting like so

theme_get_setting('myvar','mytheme');

but I don't see a way of actually setting a setting. Something along the lines of

theme_set_value('myvar','mytheme','value'); I looked at the functions available to me here https://api.drupal.org/api/drupal/core%21includes%21theme.inc/8.2.x but I didn't see anything specific to my needs.

I do see there's already a question asking the same thing here How to set theme setting but that is for Drupal 7 and I'm using 8.

Is there a quick way to set the value of a specific theme setting?

Answer 1

Drupal 8 use configuration to store configuration settings. You can follow document. And snippet code to set new value for custom theme(replace theme_name with your theme name).

$config = \Drupal::service('config.factory')->getEditable('theme_name.settings');
$config->set('variable', 'value')->save();
