Checkboxes¶
New in version 13.0
When using the check
type, TYPO3 takes care of
generating the according database field.
A developer does not need to define this field in an extension's
ext_tables.sql
file.
Introduction¶
This type creates checkbox(es).
There can be between 1 and 31 checkboxes. The corresponding database field must be of type integer. Each checkbox corresponds to a single bit of the integer value, even if there is only one checkbox.
Tip
This means that you should check the bits of values from single-checkbox fields and not just whether it is true or false.
There is a subtle difference between fields of the type check
and select
fields with the render type
selectCheckBox. For the
details please see: selectCheckBox and type check fields compared.
Warning
Resorting the 'items' of a type='check' config results in single items moving to different bit positions. It might be required to migrate existing field data if doing so.
The following renderTypes are available:
- default: One or more checkboxes are displayed.
- checkboxToggle: Instead of checkboxes, a toggle item is displayed.
- checkboxLabeledToggle: A toggle
switch where both states can be labelled (ON/OFF, Visible / Hidden or alike).
Its state can be inverted via
invertStateDisplay
