Provide a high-level introduction to the Drupal Form API and an overview of what you'll need to learn to master it. List some of the benefits of using the Form API over generic HTML formsīy the end of this tutorial you should have a solid understanding of the role of the Form API in Drupal.Explain the relationship between Form API and the Render API.Describe what forms are and how they are used in Drupal.Knowing how to make changes to the UX of a form is an important skill. Theme developers are also likely to encounter some aspects of the Form API, as forms are inherently part of the look and feel of a site. Understanding the basics should be considered required knowledge. While you may not need to know all the nitty-gritty details, every Drupal module developer is likely to encounter aspects of the Form API at some point. Given that forms are one of the primary means of interacting with a Drupal site via the UI, understanding how the Form API works is a critical part of learning to develop modules for Drupal. ![]() It uses Render Arrays to define forms, and adds an additional level of workflow and processing to enhance the Render API with some features specific to handling forms. The Form API is closely related to the Render API. com email address.Drupal's Form API is a set of interfaces, utility classes, and conventions that when combined together allow module developers to create forms that collect, validate, and process user-submitted data. If you mean to create a form programatically in the custom block, you can achieve that by creating two files shown below:įorm file ( src/Form/DemoForm.php): 'email', To build a form using block module, you can easily use Webform module where you can add a form and display as a block. Place the block in the desired region(s). I just personally like to do it that way, because often times I need to add something else to the final render array like some markup, cache settings or a library etc. ![]() Note: You don't need to wrap the $builtForm with the $renderArray, you can return just the $builtForm and be fine. The idea is basically (code updated with suggestion from Henrik): $builtForm = \Drupal::formBuilder()->getForm('Drupal\your_module\Form\YourForm') Under your_module/src/Plugin/Block/ you create the block which will render the form. Under your_module/src/Form you create the form. Then you enable it using drush or the admin area in Drupal. Look here: Naming and placing your Drupal 8 module.īasically you create the module folder and the module info yml file to let Drupal know about the module. So here is a small guide what to do, further information on how to do stuff in detail would be overkill for this answer. Your question is very vague, as I don't know how much you already know about modules, forms and blocks in Drupal 8. ![]()
