FieldInformation extends AbstractNode
Field information are additional HTML on a single node level that are typically shown between the label and the main element. They are registered in ['config']['fieldInformation'] TCA section and each element may merge that with default registered information.
Field information must not add additional functionality to the element. They are only allowed to add "informational" stuff like links, div and spans and similar.
Table of Contents
Properties
- $data : array<string|int, mixed>
- Main data array to work on, given from parent to child elements
- $defaultFieldControl : array<string|int, mixed>
- A list of default field controls added to the element / container.
- $defaultFieldInformation : array<string|int, mixed>
- A list of default field information added to the element / container.
- $defaultFieldWizard : array<string|int, mixed>
- A list of default field wizards added to the element / container.
- $nodeFactory : NodeFactory
- Instance of the node factory to create sub elements, container and single element expansions.
Methods
- __construct() : mixed
- Set data to data array and register node factory to render sub elements
- render() : array<string|int, mixed>
- Order the list of field information to be rendered with the ordering service, then call each information element through the node factory and merge their results.
- getValidationDataAsJsonString() : string
- Build JSON string for validations rules.
- initializeResultArray() : array<string|int, mixed>
- Initialize the array that is returned to parent after calling. This structure is identical for *all* nodes. Parent will merge the return of a child with its own stuff and in itself return an array of the same structure.
- mergeChildReturnIntoExistingResult() : array<string|int, mixed>
- Merge existing data with a child return array.
