Creating a Point 2D field type

This tutorial covers the creation and development of a custom Ibexa DXP field type. The Generic field type is a powerful extension point. It enables you to 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

For more information, see 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.

Intended audience

This tutorial is aimed at developers who are familiar with Ibexa DXP and are comfortable with operating in PHP and Symfony.

Content of the tutorial

This tutorial shows you how to use the Generic field type as a template for a custom field type. You:

• create a custom Point 2D field type with two coordinates as input, for example '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're able to change its output

Steps

In this tutorial you go through the following steps:

• 1. Implement the Point 2D Value class
• 2. Define the Point 2D field type
• 3. Create form for editing field type
• 4. Introduce a template
• 5. Add a new Point 2D field
• 6. Implement Point 2D settings
• 7. Add basic validation
• 8. Data migration between field type versions
