TYPO3 ver. 6.x - additional configuration a.k.a. `localconf_local.php`

Question

What we need

In TYPO3 ver. 4.x we used to include additional configuration file for overwriting some settings (ie. DB credentials) by adding the include statement at the end of the localconf.php:

@include_once('localconf_local.php');

Thanks to this trick it is possible for an example keep separate database settings or IM paths individual for each developer as we can just ignore our 'local' files from the git repository.

What's the problem

Unfortunately in TYPO3 ver. 6.x that approach requires manual changes of the LocalConfiguration.php to overwrite the values before the return statement, what's more after each operation in Install Tool (or Extension Manager) the file is completely to original syntax (so we need to change it again and again...

Question

Have you guys any workaround for this? Or this is just... impossible to do?

Answer 1

Got it! :)

The answer is: typo3conf/AdditionalConfiguration.php if this file exists it's included automatically, to overwrite some values we need to use well-known syntax ie.:

<?php
$GLOBALS['TYPO3_CONF_VARS']['DB']['database'] = 'my_local_database';
$GLOBALS['TYPO3_CONF_VARS']['DB']['host']     = 'localhost';
$GLOBALS['TYPO3_CONF_VARS']['DB']['username'] = 'username';
$GLOBALS['TYPO3_CONF_VARS']['DB']['password'] = 'mypassword';
?>
