What does it do?

This extension include PHP files based on TYPO3_CONTEXT value. This allows you to make fine tuning of TYPO3 settings based on different context: instance, feature activation, system verbosity etc.

Installation

1. Install using composer:

   composer require sourcebroker/configs
   

2. Add following code in typo3conf/AdditionalConfiguration.php

   <?php
   
   defined('TYPO3') or die();
   
   \SourceBroker\ConfigTypo3\Config::initialize()
       ->appendContextToSiteName()
       ->includeContextDependentConfigurationFiles();
   

3. Create folder context in folder config.

4. In folder context create folders that starts with 1_*, 2_*, 3_*, 4_*., example 1_verbosity, 2_mode, 3_instance

5. Inside those folders create php files with the names you will use in TYPO3_CONTEXT.

Example

1. Copy example configs from Resources/Private/Examples/Example1/context to folder config/context
2. You can change the folder names 1_verbosity, 2_mode, 3_instance to whatever you want but do not change the number_underscore pair. Numbers decide about what part of configs to read from the folders based on TYPO3_CONTEXT parts. Part after number and underscore play no role.
3. If TYPO3_CONTEXT will be set to Development/Staging/Beta then file Development.php will be included from folder 1_verbosity, file Staging.php will be included from folder 2_mode and file Beta.php will be included from folder 3_instance.

You can have as many folders with numbers as you like. You can also read more files from one folder when you separate string with comma. For example you can set TYPO3_CONTEXT to Production//Live/Feature1,Feature2 then file Production.php will be included from folder 1_verbosity, file Live.php will be included from folder 3_mode and file Feature1.php, Feature2.php will be included from folder 4_whatever.

If you install package helhum/dotenv-connector then you additionally have possibility to modify $GLOBALS['TYPO3_CONF_VARS'] array by adding entries in .env file with following convention: TYPO3__[first_level_array]__[second_level_array]__[third_level_array] = "value"

This allows you to provide database values per instance by putting following lines to .env files of each instance. The .env file should be out of git.

Example:

TYPO3__DB__Connections__Default__dbname=".."
TYPO3__DB__Connections__Default__host=".."
TYPO3__DB__Connections__Default__port=".."
TYPO3__DB__Connections__Default__user=".."
TYPO3__DB__Connections__Default__password=".."

TYPO3__GFX__processor_path=".."
TYPO3__GFX__processor_path_lzw=".."
TYPO3__GFX__processor_colorspace=".."

It is up to you to decide what values to put inside .env (which is out of git) and which to config/context/3_instance/Live.php, config/context/3_instance/Beta.php etc which are inside git.

Lot of values stored in .env file means that it is harder to recreate the same TYPO3 state on local development system. If those settings are in git then you can just switch TYPO3_CONTEXT from local TYPO3_CONTEXT=Development/Staging/Local to beta TYPO3_CONTEXT=Production/Staging/Beta on local development system.

Database access data are good candidate to be put inside .env.

Uncache exceptions

You can use following code to disable uncaching on development for some cache configurations:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['configs']['caching']['cacheConfigurations']['my_cache']['uncache'] = false
