Content Entity

This cheat sheet provides an overview of the frequently used methods, classes, and interfaces for content entities.

Content entities inherit many of their behavior from entities. See Working with the Entity API for these generic functions.

Manipulating field values

• Create custom fields using the baseFieldDefinitions() method for the content entity
• Define a custom field called custom_field
• Store a custom entity instance in a local variable ($custom_entity)
• Store some data

Example code

$custom_field_value = $custom_entity->custom_field->value;
// Manipulate the field data.
// Store the field data back into the entity field.
$custom_entity->custom_field->value = $custom_field_value;
// Save the entity.
$custom_entity->save();
