This function is used to provide modifications to the form in the CMS by the extension. By default, no changes are made. {@link DataObject->getCMSFields()}.

Please consider using {@link updateFormFields()} to globally add formfields to the record. The method {@link updateCMSFields()} should just be used to add or modify tabs, or fields which are specific to the CMS-context.

Caution: Use {@link FieldList->addFieldToTab()} to add fields.

This function is used to provide modifications to the Validators used on a DataObject.

Caution: Use {@link CompositeValidator->addValidator()} to add Validators.

This function is used to provide modifications to the form used for front end forms. {@link DataObject->getFrontEndFields()}

Caution: Use {@link FieldList->push()} to add fields.

This is used to provide modifications to the form actions used in the CMS. {@link DataObject->getCMSActions()}.

this function is used to provide modifications to the fields labels in CMS by the extension By default, the fieldLabels() of its owner will merge more fields defined in the extension's $extra_fields['field_labels']

Extension point in see DataObject::duplicate()

Extension point in see DataObject::duplicate()

Finds the top-level SiteTree object for a Block / ElementalArea, using the cached TopPageID reference when possible.

Set top page to an object If no page is provided as an argument nor as a fixed id via see DataExtension::withFixedTopPage() automatic page determination will be attempted Note that this may not always succeed as your model may not be attached to parent object at the time of this call

Use this to wrap any code which is supposed to run with fixed top page Useful when top page is known upfront and doesn't need to be determined For example: model duplication where parent is assigned and saved only after the duplication is done It's not possible to determine top page in such case however it might be possible to know the top page even before the operation starts from the specific context Setting the page id to 0 disables this feature
