How to Create a Custom Form in Drupal with Validation and Submission Handling
Creating custom forms in Drupal is a straightforward process using Drupal’s Form API, as explained by Mohammad Anwar Siddiqui in his blog on Medium. By extending the FormBase class, you can define your form fields, handle form validation, and manage submissions. The form includes essential fields like name and email, with built-in validation for length and proper email formatting. After successful validation, the form submission can be processed, such as displaying a success message or saving data. By defining routes and permissions, you can control access to your custom form, ensuring security and flexibility within your Drupal site. This approach allows developers to create dynamic and user-friendly forms tailored to specific needs.
