This skill handles basic knowledge on how the DataHandler, a TYPO3 Core component for processing user data, works and how it can be leveraged in own extensions.
Core Architecture & APIs,
- I know how the DataHandler processes data entered in forms in the Backend.
- I know about hooks I can use for modifying data during processing.
- I know how to use DataHandler in my own extensions (e.g. for mass-creation of records).
- I can modify data during the processing of certain tasks (e.g. versioning).
