What it does

The current TYPO3 Constant Editor does not support enough native field types. This extension hooks into the TypoScript processing pipeline to add custom data types, enabling a more sophisticated and precise generation of backend configuration options.

Installation

Just install the extension. It works seamlessly out-of-the-box with any modern extension configured to support extended types.

This extension operates fully update-safe and compliant with the native TYPO3 v14 Core database storage layout, avoiding any core overrides or legacy hooks.

Reference

Syntax:

Custom types are declared directly inside the TypoScript constant configuration comments using the standardized UserFunction syntax:

# type=user[JambageCom\Tsparser\UserFunction\RenderEintPlus->render]

Constant Editor Types:

See the official TYPO3 Constant Editor Documentation <https://typo3.org> for a complete list of native constants types.

New configuration types provided by this extension:

RenderEintPlus (formerly eint+) … empty or integer.

If nothing has been entered into the backend field, the constant value remains completely empty in the template. Be aware that an empty constant signifies that nothing is intended or configured, which behaves technically different from explicitly setting a value to 0.

Examples:

To clear a default configuration value (e.g., allowing all products across all categories by leaving the category filter empty), configure the behavior in your extension's constants.typoscript file:

# cat=plugin.products//; type=user[JambageCom\Tsparser\UserFunction\RenderEintPlus->render]; label=default category ID: ID of the default category that will be shown in the list view when no tt_products[cat] parameter is given
defaultCategoryID =

jambagecom / tsparser
