Field is the smallest unit for storing data in the content structure. Each Field can store data of a specific kind, defined by a Field Type.
To read more about the content structure in eZ, see .
The characteristics of a Field are determined by its Field Type. In eZ, a Field is made up of the following elements:
Example: The title of the Article
Example: A brief description of the Article
Take the “Content relation (multiple)” Field Type: you can decide to have relation only to Content items of a specific Content Type or to Content items of any Content Type.
Basically, all Field Types have different properties.
You have an option of creating your own, custom Field Types, at a developer lever using PHP.
Below are listed the preset Field Types existing in every installation, as well as their specific controls.
