Drupal Fix Addresses Unexpected Form Submissions

A longstanding issue in Drupal that caused unexpected form submissions when users pressed the Enter key has finally been resolved. The fix, which introduces a new key, '#submit_button,' was committed to Drupal core and will be available in version 11.2.0.

Sean Blommaert, Director of Awesomeness at TwelveBricks, highlighted the issue in a recent LinkedIn post, noting that Drupal previously did not allow developers to use 'type="button",' only 'type="submit"'. This limitation led to unintended form actions, as browsers automatically trigger the first submit button when the Enter key is pressed.

The new '#submit_button' key, introduced in branch 10.5.x, allows developers to define whether a button should submit a form. When set to 'FALSE,' the button functions as a standard HTML button without triggering a form submission or page refresh. The change offers more flexibility and resolves multiple related issues tied to form behavior.

This update is expected to significantly improve the user experience for Drupal developers and end users alike. Module developers are encouraged to review their implementations and adjust button types accordingly.
