I have a settings form that saves site wide configuration information My submit form function looks something like this
$data = []; foreach ($groups as $key) { $data[$key] = $form_state->getValue($key); if (empty($data[$key])) { $data[$key] = []; } } $this->configFactory ->getEditable('my_config.settings') ->setData($data) ->save(); My issue is that in a callback I’d like to be able to directly set the value of a single configuration field that is nested in that data array without grabbing everything again and changing the data array and resetting it with ->setData
The data in my config array looks like this
[ 'num_campaigns'=> 4 'campaigns'=> [ 'campaign_ids' => ['abc','def','ghi','jkl'] ] ] And my callback looks like this
public function removeField(array $form, FormStateInterface $form_state){ $config = $this->getConfig(); $num_campaigns = $config['num_campaigns']-1; $config_factory = $this->configFactory->getEditable('my_config.settings'); $config_factory->set('num_campaigns', $num_campaigns); $config_factory->set(['campaigns','campaign_ids',$num_campaigns], '') $config_factory->save(); $form_state->setRebuild(); } My issue is that the set method accepts a string and not an array. If I can only supply a string how do I set the value of something that is nested down in my config array? Is using set even an option? Or do I have to resort to using setData?
