Content entities inherit much of their behavior from entities. See Working with the Entity API for those shared features.

Managing Field Values

Create custom fields using the baseFieldDefinitions method for your content entity.

Load an instance of your custom entity into a local variable $Custom_Entity
Define a custom field named custom_field
Store some data

Code Example

$custom_field_value = $Custom_Entity->custom_field->value;
// Perform some kind of data manipulation
$Custom_Entity->custom_field->value = $custom_field_value;
$Custom_Entity->save();

Examples of content entities:

node
comment
user
