Typo3 Powermail

TYPO3 Powermail Development

Source: https://github.com/dirnbauer/webconsulting-skills

Compatibility: Upstream Powermail 13.x targets TYPO3 13.4 and has no v14 release. For a 14.3 project install the maintained fork — see Powermail on TYPO3 v14. Examples use modern TYPO3 APIs where possible; adjust for your Core version. All examples use PHP 8.2+.

TYPO3 API First: Always use TYPO3's built-in APIs, core features, and established conventions before creating custom implementations. Do not reinvent what TYPO3 already provides. Always verify that the APIs and methods you use exist and are not deprecated in TYPO3 v14 by checking the official TYPO3 documentation.

Supplements:

• SKILL-CONDITIONS.md - Conditional field/page visibility (powermail_cond)
• PHP 8.4 patterns for finishers, validators, and conditions are covered directly in this skill
• SKILL-EXAMPLES.md - Multi-step shop form with Austrian legal types, DDEV SQL + DataHandler CLI

Powermail vs Core EXT:form

These are different systems. Do not mix migration advice between them.

Sections labeled EXT:form under v14-Only Changes describe Core form-framework removals (hooks → PSR-14, storage adapters). They apply to custom code that hooks into EXT:form, not to ordinary Powermail-only projects—unless you explicitly integrate both.

Powermail on TYPO3 v14

Upstream in2code/powermail has no v14 release yet — its newest line still requires typo3/cms-core: ^13.4, so a plain composer require in2code/powermail will not resolve in a 14.3 project. Until upstream ships v14, install the maintained fork:

{
    "repositories": [
        { "type": "vcs", "url": "https://github.com/dirnbauer/powermail" }
    ],
    "require": {
        "in2code/powermail": "dev-typo3-v14"
    }
}

ddev composer config repositories.powermail vcs https://github.com/dirnbauer/powermail
ddev composer require in2code/powermail:dev-typo3-v14

The fork keeps the package name in2code/powermail, so it is a drop-in replacement — the VCS repository entry simply wins over Packagist for that package. Its typo3-v14 branch declares typo3/cms-core: ^14.3; a typo3-v13 branch also exists for sites still on v13.

Two things to carry into any handover, because a dev- requirement is not a released version:

• It pins to a branch, not a tag. composer update follows the branch, so a deploy can pick up changes that were never reviewed. Commit composer.lock and treat an update of this package as a change that needs re-testing, not a routine bump.
• Revisit it. When upstream publishes a v14 release, drop the repositories entry and require the released version instead. Record the fork in the deployment handover as technical debt with that exit condition, so it is not still there in two years.

1. Architecture Overview

Domain Model Hierarchy

Form (tx_powermail_domain_model_form)
 └── Page (tx_powermail_domain_model_page)
      └── Field (tx_powermail_domain_model_field)

Mail (tx_powermail_domain_model_mail)
 └── Answer (tx_powermail_domain_model_answer)
      └── references Field

Plugin Registration

• Pi1 (cached/uncached): form, create, confirmation, optinConfirm, disclaimer
• Pi5 (uncached): marketing (AJAX tracking)

Composer

composer require in2code/powermail

Typical requirements (always confirm the current release on Packagist): PHP ^8.2, typo3/cms-core: ^13.4 — the newest upstream powermail line still targets v13.4 and has no v14 release, so this is a genuine blocker for a v14 project, not an oversight. See "Powermail on TYPO3 v14" below for what to install meanwhile. Plus ext-json, ext-gd, ext-fileinfo, ext-curl. Do not assume TYPO3 v14 until the package constraint is updated upstream.

2. Field Types

Answer Value Types

Answer::VALUE_TYPE_TEXT     = 0;  // String values
Answer::VALUE_TYPE_ARRAY    = 1;  // JSON-encoded arrays (checkboxes, multiselect)
Answer::VALUE_TYPE_DATE     = 2;  // Timestamps
Answer::VALUE_TYPE_UPLOAD   = 3;  // File references
Answer::VALUE_TYPE_PASSWORD = 4;  // Hashed passwords

3. TypoScript Configuration

Essential Settings

    settings {
        setup {
            # Form settings
            main {

                form = {$plugin.tx_powermail.settings.main.form}
                confirmation = 0
                optin = 0
                morestep = 0
            }

            # Receiver mail
            receiver {
                enable = 1
                subject = Mail from {firstname} {lastname}
                body = A new mail from your website
                senderNameField = firstname
                senderEmailField = email
                # Override receiver: receiver.overwrite.email = admin@example.com
                # Attach uploads: receiver.attachment = 1
                # Add CC: receiver.overwrite.cc = copy@example.com
            }

            # Sender confirmation mail
            sender {
                enable = 1
                subject = Thank you for your message
                body = We received your submission
                senderName = Website
                senderEmail = noreply@example.com
            }

            # Double Opt-In
            optin {
                subject = Please confirm your submission
                senderName = Website
                senderEmail = noreply@example.com
            }
