How to access the ext_conf_template.txt (extension configuration) in typoscript? - typo3

Question

There are a few settings in the ext_conf_template.txt in my extension.
I want to check the value of one of these settings, but in typoscript, not in PHP.
In PHP it works like this:
unserialize($GLOBALS['TYPO3_CONF_VARS']['EXT']['extConf']['myExt'])
How should I do this in typoscript?

Answer 1

Thanks to the answer of Marcus I was able to get a extension configuration setting into typoscript. First create the extension setting in ext_conf_template.txt:
# cat=Storage; type=string; label=storageFolderPid
storageFolderPid = 1
In ext_local_conf.php add the following lines:
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTypoScriptConstants(
"plugin.tx_extensionname.settings.storageFolderPid = ".$GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['extension']['storageFolderPid']
);
Then you can use this variabele in your typosript, for instance to create a submenu of a storage folder:
lib.submenu = CONTENT
lib.submenu {
table = tx_extension_domain_model_article
select {
pidInList = {$plugin.tx_extensionname.settings.storageFolderPid}
selectFields = tx_extensionname_domain_model_article.*
}
...
}

I did something similar in my code snippet extension (see complete code on Github), where I just added a custom TypoScript condition:
[DanielGoerz\FsCodeSnippet\Configuration\TypoScript\ConditionMatching\AllLanguagesCondition]
// some conditional TS
[global]
The condition implementation is quite simple:
namespace DanielGoerz\FsCodeSnippet\Configuration\TypoScript\ConditionMatching;
use DanielGoerz\FsCodeSnippet\Utility\FsCodeSnippetConfigurationUtility;
use TYPO3\CMS\Core\Configuration\TypoScript\ConditionMatching\AbstractCondition;
class AllLanguagesCondition extends AbstractCondition
{
/**
* Check whether allLanguages is enabled
* #param array $conditionParameters
* #return bool
*/
public function matchCondition(array $conditionParameters)
{
return FsCodeSnippetConfigurationUtility::isAllLanguagesEnabled();
}
}
And the check for the actual TYPO3_CONF_VARS value is done in FsCodeSnippetConfigurationUtility:
namespace DanielGoerz\FsCodeSnippet\Utility;
class FsCodeSnippetConfigurationUtility
{
/**
* #return array
*/
private static function getExtensionConfiguration()
{
return unserialize($GLOBALS['TYPO3_CONF_VARS']['EXT']['extConf']['fs_code_snippet']);
}
/**
* #return bool
*/
public static function isAllLanguagesEnabled()
{
$conf = self::getExtensionConfiguration();
return !empty($conf['enableAllLanguages']);
}
}
Maybe that fits your needs.

Handle the configuration via Extension Manager and call ExtensionManagementUtility::addTypoScriptConstants() in your ext_localconf.php to set a TypoScript constant at runtime.
This way the value can be set at one location and is available both in lowlevel PHP and TypoScript setup.
