Creating a Tweet Field Type

Getting the code

The code created in this tutorial is available on GitHub: (https://github.com/ezsystems/TweetFieldTypeBundle).

This tutorial covers the creation and development of a custom eZ Platform Field Type. Field Types are the smallest building blocks of content. eZ Platform comes with about 30 native types that cover most common needs (Text line, Rich text, Email, Author list, Content relation, Map location, Float, etc.)

Field Types are responsible for:

  • Storing data, either using the native storage engine mechanisms or specific means
  • Validating input data
  • Making the data searchable (if applicable)
  • Displaying Fields of this type

Custom Field Types are a very powerful type of extension, since they allow you to hook deep into the content model.
