TYPO3 Extbase, 3rd Edition (English)
TYPO3 Extbase, 3rd Edition (English)
Modern Extension Development for TYPO3 CMS with Extbase and Fluid
About the Book
Extensions play a central role in the development of complex TYPO3 CMS installations. To build effective solutions, every TYPO3 developer needs to know specific programming techniques. Today, the Extbase Framework and the Fluid Templating Engine are regarded as the standard.
This technical book is suited for both beginners and seasoned TYPO3 developers and provides all you need to know to plan and implement projects of any size with Extbase and Fluid. From the basics of object-oriented programming in PHP to the principles of domain-driven design (DDD) and the model-view-controller concept (MVC), the book explains theoretical foundations as well as practical solutions in an easily understandable way. An easy to follow introduction to the basics is followed by a step-by-step guide to developing real-world, complex scenarios using best practices. A dedicated chapter provides details on coding and security standards in TYPO3 and on how to add measures of security and avoid typical vulnerabilities when building extensions.
Gain insight to this advanced topic and learn how to write clean code that complies to modern standards and programming principles for TYPO3 v9 LTS and newer.
