BUILD ROBUST FORMS IN DRUPAL 8

Building Robust Forms with Drupal 8

Over the last few Drupal releases, the Webform module has been the standard for creating robust forms and surveys. While this venerable module has served the community’s needs quite well, major releases of Drupal often afford the opportunity to take a fresh look at how common problems are solved, leveraging new technologies and concepts introduced in the release.

Baked into Core

Since Drupal 4.6, Drupal Core has shipped with a basic contact form module that had limited functionality. Finally, the contact module got some much-needed attention in Drupal 8. Contact forms are now fieldable entities, allowing us to build forms with the same fields we build content types, taxonomies, and other entities with.

Building Out the Form

Forms are created and managed by navigating to Structure->Contact Forms in the Admin menu. From here, choose “Add contact form.”

Drupal 8 Contact Form Admin

This takes us to a form for setting the name of the form, email addresses for submissions to be sent to, and optionally an auto-reply message to the submitter. Once saved, we are taken back to the Contact Forms admin page.

Add Contact Form

This gives us a basic form with Sender Name and Email, a Subject field, and a basic text area for a Message. To add fields to our new form, we need to select the “Manage Fields” option in the Operations dropdown. From here, we can add any of the field types available on the site.

Add fields

Form Display

To customize how the form is displayed, we want to select the “Manage Form Display” option in the Operations dropdown. This will allow us to change the order of the fields for the form, change configurations for each field, and allow us to disable any fields that are provided by default that we don’t want to use.

Manage Display

Similar to Form Display, if we want to change the order and display of fields in the submission emails, using the “Manage Display” option will allow us reorder or hide fields from showing in the submission email.

Submission Storage and Export

Everything we’ve covered so far is great if we want to build out a form and start getting submissions by email. However, if we want to save and view submissions in the site or want to export the submissions in bulk, we need to look to some contributed modules to fill in the gaps.

Contact Storage Module

As its name implies, the Contact Storage module addresses the need for a central location from which content editors can review and manage form submissions on the site. The module also provides Views integration as well as some additional customization options for our forms. The default configuration provides these features for us, so we can install the module and start benefitting from it immediately.

Submission Exports

We now have robust forms and a place to centrally store their submissions, with Views giving us the ability to build out lists of submissions. What we’re still missing at this point is a way to download the submissions in bulk, and it’s fairly common to want such an export in a format like CSV that can be loaded into a spreadsheet application. To achieve that, we can put our Views integration to use, along with Drupal 8’s REST Module, and the CSV Serialization module.
