I struggled with TYPO3 forms for a long time and refused to use or update it, because there is no documentation that just works. But I needed to integrate a newsletter subscription form for Brevo and there was a finished integration from studiomitte, so I needed to dig into this topic, and made a full template extension just for T3:Forms, that can be used for tutorials or as a fork for your own projects.

Installation

Install via composer

composer req bokuno/form-collection

Load TypoScript from Extension "form" and "form_collection"
Clear Cache
As the contact form is already present you can simply use it in the form plugin
