Simplifying Drupal 10 Configurations with '#config_target' Option

Staff Reporter

QED42's blog post, "Exploring the new '#config_target' option in Drupal 10," explains how this feature simplifies configuration form creation and validation. Traditionally, Drupal developers used the validateForm() method to validate configuration forms. The new '#config_target' property, introduced in Drupal 10.2, allows validations to be added directly from the schema.yml file.

The blog demonstrates how to use '#config_target' to store values and perform transformations within configuration forms. It covers adding validation constraints such as NotBlank and Choice, and even creating custom constraints like SaveIronman. This new approach offers enhanced flexibility and ensures consistent validation, even when programmatically saved configurations. The post concludes by highlighting the advantages of adopting '#config_target' for future Drupal releases.
