TYPO3 Extension Development

Chapter 2. Anatomy of TYPO3 Extension

This chapter describes TYPO3 extensions from the developer's point of view. After reading this chapter, the reader will have basic knowledge of extension structure, files, and how extensions interact with TYPO3. This knowledge is necessary for extension planning and implementation.

TYPO3 Extension Categories

All TYPO3 extensions are classified into several predefined categories. These categories do not actually differentiate the extensions. They are more like hints for users about extension functionality. Often, it is difficult for the developer to decide which category an extension should belong to. The same extension can provide PHP code that fits into many categories. An extension can contain Frontend (FE) plugins, Backend (BE) modules, static data, and services, all at once. While it is not always the best solution to make such a monster extension, sometimes it is necessary. In this case, the extension author should choose the category that best fits...

TYPO3 Extension Categories


All TYPO3 extensions are classified into several predefined categories. These categories do not actually differentiate the extensions. They are more like hints for users about extension functionality. Often, it is difficult for the developer to decide which category an extension should belong to. The same extension can provide PHP code that fits into many categories. An extension can contain Frontend (FE) plugins, Backend (BE) modules, static data, and services, all at once. While it is not always the best solution to make such a monster extension, sometimes it is necessary. In this case, the extension author should choose the category that best fits the extension's purpose. For example, if an extension provides a reservation system for website visitors, it is probably FE related, even if it includes a BE module for viewing registrations. If an extension provides a service to log in users, it is most likely a service extension, even if it logs in FE users. It will...

Extension Files


TYPO3 extensions consist of several files. Some of these files have predefined names, and serve a predefined purpose. Others provide code or data but also follow certain naming conventions. We will review all the predefined files in this chapter and see what purpose they serve. We will look into the files according to their logical grouping.

While reading this section, you can take any extension from the typo3conf/ext/ directory at your TYPO3 installation and check the contents of each discussed file. Some files may be missing if the extension does not use them. There is only one file which is mandatory for any TYPO3 extension, ext_emconf.php. We will start examining files starting from this one.

Common Files

All files from this group have predefined names, and TYPO3 expects to find certain information in them. Hacking these files to serve another purpose or to have a different format usually results in incompatibility with other extensions or TYPO3 itself. While it may work...

Summary


In this section, we learned about extension files and extension classes. Now, the reader will have a basic knowledge of the extension structure and the extension components. In the forthcoming chapters, we will take a deeper look into extensions, and at coding our own extensions.

Also, ich war schon etwas entäuscht, als ich diese "Broschüre" in Händen hielt. Hiermit sollte/wollte ich also in die Extension-Entwicklung einsteigen ... Mittlerweile habe ich 3 eigene Extensions geschrieben und finde immer noch etwas Neues in dem "Büchlein" ... Es ist halt sehr kompaktes Wissen und keine Gute-Nacht-Lektüre. Insgesamt habe ich es bestimmt 3mal gelesen. Das erste Mal, um mir einen groben Überblick zu verschaffen. Dann habe ich mit der Programmierung angefangen und regelmäßig wieder ins Buch geschaut. Und mit der Erfahrung von 1-2 eigenen Extensions habe ich das Buch nochmal gelesen und hatte regelmäßig einen Aha-Effekt.Dennoch gibt es von mir "nur" 4 Sterne. Das Buch ist wirklich empfehlenswert, aber fürs Geld fehlen noch 100-200 Seiten. Im Buch wird die Entwicklung anhand eines Beispiels gezeigt. Ein sanfterer Einstieg, die Entwicklung einer Mini-Extension und dann die Entwicklung einer größeren Extension - das wäre ideal gewesen.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

How do I buy Early Access content? Chevron down icon Chevron up icon

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access? Chevron down icon Chevron up icon

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.
