Creating a Custom Configuration Form in Drupal 10
Himanshu Jhaloya shared a detailed blog post on creating a custom configuration form in Drupal 10. The guide begins with creating a custom module directory, named custom_config_form, and defining its .info.yml file. Next, it involves creating a form class (CustomConfigForm.php) that extends ConfigFormBase and implements essential methods like getEditableConfigNames, getFormId, buildForm, validateForm, and submitForm.
The custom_config_form.routing.yml file defines the route for accessing the form at /admin/config/custom-config-form, while the custom_config_form.permissions.yml file specifies permissions for administering the form. After enabling the module via Drush or the Drupal admin interface, users can navigate to the specified path to access the configuration form. The post also includes tips on adding more fields and customizing validation and submission methods for enhanced functionality.
