TypoScript outside of Frontend context

Published: , Updated:

Tested with TYPO3: 11 LTS, 10 LTS, 9 LTS, 8 LTS

Topics: typo3, typoscript, extbase

TypoScript by concept is meant for frontend context only. There is TSconfig for backend as well. Extbase introduced a way to also configure backend modules via TypoScript. Nowadays TypoScript is also used in other context, e.g. scheduler tasks or commands.

I'll explain how the actual TypoScript is loaded, so you understand that part and can use it.

Topics: typo3, extbase

Since TYPO3 10.0 it is possible, actually necessary, to use FQCN (=Fully Qualified Class Names) for controllers when configuring plugins and modules. This provides a new benefit in terms of reusing and sharing code between different extensions.

This blog post will explain the benefit and provide an outlook in a possible future of TYPO3 Extbase extensions.

TYPO3 tracking extension

Published: , Updated:

Tested with TYPO3: 11 LTS, 10 LTS

Topics: project, typo3

I've created a small tracking extension for TYPO3. This should basically demonstrate what developers can achieve with newest APIs inside of TYPO3 v10.

It also provides widgets and works as a showcase for the new EXT:dashboard.

Two of our customers requested us to extend the extension for their TYPO3 installations. Therefore we added some more features and are now releasing the extension for public use.

Tested with TYPO3: 11 LTS, 10 LTS

Topics: video, tutorial, talk

I prerecorded a talk for the t3oce 2020. The talk should introduce beginners into the concepts of TYPO3. It should explain how to add and edit content, as well as what content in Context of TYPO3 actually is. Once one knows these basic concepts, I explain how to render content with TYPO3.

The talk should work as an basic introduction into TYPO3 for integrators as well as developers.

TYPO3 content caching

Topics: typo3, typoscript

TYPO3 provides a comprehensive caching implementation. Built into all parts of TYPO3. By default TYPO3 tries hard to provide a working caching solution for Websites. This way all generated content is cached whenever possible and delivered right from cache without rendering. This leads to some issues if dynamic content is added. Some bypass this issue by deactivating caching partly or for whole pages.

This post explains how to configure TYPO3 to make caching work without deactivating it. One place where caching does not work out of the box is changing files via Filelist module, changes there will not be reflected in content elements using a file reference. This example is used to explain how caching works in TYPO3 and how to adjust caching.

From time to time you need to test some email within your TYPO3 installation. Whether it might be that you are a developer sending some mail via a CommandController or Plugin, or you are an integrator configuring EXT:powermail or EXT:form to deliver some mail.

In all cases you need to make sure this mail is not send to external addresses like your customer during development and testing. Also you need to be able to check the content of the mail. In this blog post you will learn what mbox is and how to use it.
