dbFieldLength¶

New in version 13.0

As TYPO3 takes care of generating the according database field for select fields since TYPO3 v13, a developer can adjust the length of the database field with this option in TCA directly.

dbFieldLength ¶

Type: integer
Path: $GLOBALS['TCA'][$table]['columns'][$field]['config']
Default: 255
Scope: Proc.
RenderType: all

The TCA config option dbFieldLength has contains an integer value that is applied to varchar fields (not text) and defines the length of the database field. It will not be respected for fields that resolve to an integer type. Developers who wish to optimize field length can use dbFieldLength for type=select fields to increase or decrease the default length.
