Drupal Fields
Creating Fields (Drush — CLI First)
Always use drush field:create instead of manually creating field config files.
bash# Interactive (recommended first time) drush field:create # Non-interactive drush field:create node article \ --field-name=field_subtitle \ --field-label="Subtitle" \ --field-type=string \ --field-widget=string_textfield \ --is-required=0 \ --cardinality=1 # Reference field drush field:create node article \ --field-name=field_tags \ --field-label="Tags" \ --field-type=entity_reference \ --field-widget=entity_reference_autocomplete \ --cardinality=-1 \ --target-type=taxonomy_term # Image field drush field:create node article \ --field-name=field_image \ --field-label="Image" \ --field-type=image \ --field-widget=image_image \ --is-required=0 \ --cardinality=1
Managing Fields
bash# List all fields on a content type drush field:info node article # Delete a field drush field:delete node.article.field_subtitle # Discover available types/widgets/formatters drush field:types drush field:widgets drush field:formatters
Export After Creating Fields
bash# Always export config after CLI changes drush config:export -y
Custom Field Type (Plugin)
bashdrush generate plugin:field:type drush generate plugin:field:formatter drush generate plugin:field:widget
Accessing Field Values in Code
php// Single value $value = $entity->get('field_name')->value; // Entity reference $referenced = $entity->get('field_ref')->entity; // Multi-value foreach ($entity->get('field_multi') as $item) { $value = $item->value; }
