How to Build Custom Forms in Drupal 8?

Introduction: Building Complex Forms in Drupal 8

This Tutorial will show how to build custom Forms in Drupal 8 with Fields, Content Types, Webform, & the core ContactForm module that all collect queried information from users.

Step Two:

Configure the Site-Wide Contact Form

Start: The Drupal 8 Contact Form allows any user who browses a website to send a email to the site owner. The Contact Form can also be customized with Fields for data collection. Next: Navigate to admin/structure/contact & add a new Contact Form. Hint:Drupal 8 gives administrators the ability to create multiple contact forms, i.e. a site-wide form for anonymous users, business inquiry by a department, or special offer promotions. Configuration: Enter required values for the Label, Recipients (email addresses), Display Messages, & Redirect Path. Save the settings then use the path URL for menu links.

Step Three:

Build a Webform for Custom Form Requirements

Start: The Webform module for Drupal 8 is sponsored and includes video tutorial content with sample Form content to get started. Navigate to: admin/structure/webform Next: Click on the link to “Add New Webform” & enter a name in the pop-up screen. On the form build page, click on the link “Add Element” and choose the type of Field required in the pop-up. Finish: Add fields for customer address, phone number, & email or use text fields for more lengthy written responses from consumers on surveys. Link the Webform URL to menu GUIs.

Step Four:

Use CCK Fields & Nodes for Advanced Solutions

Start: Another way to build forms for users in Drupal 8 is to add custom Fields to Content Types, and then use the node create (node/add/***) form for registered users to submit data. Next: Navigate to admin/structure/types/add and add a new Content Type to the CMS. Next: Navigate to admin/structure/types and click on “Manage Fields” to build the custom form. Use fields for address, email, phone number, images, pdf files, text responses, or html text. Important: Make sure to set Permissions for User Roles on the content type used as a form at: admin/people/permissions so that users cannot view the response data that is collected. Finish: Use the node create page for the Content Type or embed the form in a Block for Panels pages. Drupal 8 Fields can also be integrated with Views for custom display pages.

Conclusion: Build Forms with Custom Fields in Drupal 8

Summary: The Contact Form is an essential part of any CMS website, while the Webform module for Drupal 8 is best for creating advanced custom forms with many different field values. Recommendation: Use custom Fields on D8 Content Types for Form solutions that require better Views integration or install the Webform Views Integration module for panel displays.
