Feature Flags

This document explains how to use feature flags. We separate between two different kinds of feature flags:

Feature

Feature flags allow you to enable or disable specific features in your installation. \ This is of particular importance to disable features that have not passed the approval process.

Optional

Optional flags allow you to (de-)activate specific features for your installation. \ A practical use for these is the (de-)activation of an extension.

For more information about feature flags in TYPO3, please refer to the official TYPO3 Documentation on Feature Flags.

Feature Flag Configuration

Feature and Optional flags are configured in the .env or the local-dev/.ddev/docker-compose.environment.yaml file on ddev machine. To add a feature flag, use the following syntax:

# FEATURE FLAG
- TYPO3__SYS__features__GSB11_FEATURE_123_NEW_FEATURE=%const(bool:true)%
# OPTIONAL FLAG
- TYPO3__SYS__features__GSB11_OPTION_123_ENABLE_EXTENSION=%const(bool:true)%

In this example, both feature flags, GSB11_FEATURE_123_NEW_FEATURE and GSB11_OPTION_123_ENABLE_EXTENSION, are set to true. To disable the feature, change the value to false or delete the setting.

Feature Flag Truth Table

This table illustrates the behavior of feature flags in various states.

Usage in PHP Code

To use a feature flag in your PHP code, you can check the flag's value with the isFeatureEnabled() method of the Features class:

if (GeneralUtility::makeInstance(Features::class)->isFeatureEnabled('GSB11_FEATURE_123_NEW_FEATURE')) {
    echo 'Feature is enabled';

    // Feature-specific code
    ...
}

Usage in Fluid Templates

Feature flags can also be checked in your Fluid templates with TYPO3's Feature ViewHelper.

Basic usage

<f:feature name="GSB11_FEATURE_123_NEW_FEATURE">
   This is being shown if the flag is enabled
</f:feature>

Feature > then > else

<f:feature name="GSB11_OPTION_123_ENABLE_EXTENSION">
    <f:then>
        Flag is enabled
    </f:then>
    <f:else>
        Flag is undefined or not enabled
    </f:else>
</f:feature>

Current feature flags of gsb_consent

Usage

Nothing to do.

Consent tracking table

Note: A previous version of this extension used the table tx_gsbconsent_consentgiven for storing user consent.

Due to a missing primary key, we cannot use that table anymore.

There is an upgrade wizard to the new table tx_gsbconsent_consentgiven2.
