README

TYPO3 extension repeatable_form_elements

Note

This is a fork of tritum/repeatable_form_elements, the original extension by Ralf Zimmermann / dreistrom.land. This fork adds TYPO3 v14 compatibility, PSR-14 event migration, CI/CD infrastructure and a DDEV-based multi-version test environment.

A TYPO3 extension that adds a Repeatable container element to the TYPO3 form framework. It allows editors to create container elements with any type of fields. In the frontend, users can dynamically add and remove copies of the container. Validation is copied automatically and all form finishers are aware of the duplicated fields.

📋 Requirements

Requirement	Version
PHP	8.2 – 8.5
TYPO3	13.4 LTS, 14.x

🚀 Installation

composer require move-elevator/typo3-repeatable-form-elements

Add the site set tritum/repeatable-form-elements to the dependencies of your site package's site set:

# Configuration/Sets/YourSitePackage/config.yaml
dependencies:
  - tritum/repeatable-form-elements

💡 Usage

1. Open the TYPO3 form editor and create or open a form.
2. Add a new element — the modal lists the Repeatable container.
3. Add fields with validators to the container.
4. In the frontend, the container renders as a <fieldset> with copy and remove buttons.

Extended SaveToDatabaseFinisher

An extended version of the SaveToDatabaseFinisher is included for persisting repeatable container data. See the example form definition.

⚙️ Configuration

To deactivate the copying of variants, disable the feature flag:

$GLOBALS['TYPO3_CONF_VARS']['SYS']['features']['repeatableFormElements.copyVariants'] = false;

🔌 Extendability

Event	Description
CopyVariantEvent	Modify or disable specific copied variants during container duplication.
AfterBuildingFinishedEvent	React after a form renderable has been built/copied by the repeatable container logic. Replaces the removed afterBuildingFinished SC_OPTIONS hook.
