Creating a Point 2D Field Type¶
Getting the code
The code created in this tutorial is available on GitHub.
This tutorial covers the creation and development of a custom eZ Platform Field Type based on a Generic Field Type. The Generic Field Type is a very powerful extension point. It enables you to easily build complex solutions on a ready-to-go Field Type template.
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
You can find more information in Field Type documentation. It describes how each component of a Field Type interacts with the various layers of the system, and how to implement them.
This tutorial is aimed at developers who are familiar with eZ Platform and are comfortable with operating in PHP and Symfony.
Content of the tutorial¶
This tutorial will show you how to use the Generic Field Type as a template for a custom Field Type. You will:
- Create a custom Point 2D Field Type with two coordinates as input, e.g. (4,5)
- Register the new Field Type as a service and define its template
- Add basic validation to your Point 2D
- Add data migration to the Field Type so you will be able to easily change its output
In this tutorial you will go through the following steps:
