TYPO3 Core

Is this a feature or a bug. Should it be working like this? What do the docs say?

As config.range is not in the key list:
http://docs.typo3.org/typo3cms/TSconfigReference/PageTsconfig/TCEform/Index.html

It's a feature.

Hi All

I would like to put a +1 on this bug.

Having the problem in powermail, to make a field optional

TCEFORM.tx_powermail_domain_model_page.title.config.size = 100 <= works
TCEFORM.tx_powermail_domain_model_page.title.config.eval = trim <= do not work
TCEFORM.tx_powermail_domain_model_page.title.config.eval := removeFromList(required) <= do not work

:'(

Hi,

I can confirm, that overriding eval does not work.

• There is one sysfolder where only news of type internal url is allowed.
• The url should be optional, therefore I've set the following Page TS config in this sysfolder:
  TCEFORM.tx_news_domain_model_news.internalurl.config.eval = trim

The workaround in comment 7 of #14669 could work, but it would be more comfortable to use Page TS config.

Kind regards
Andreas

As there doesn't seem to be any possibility to manipulate the allowOverrideMatrix after the getMainFieldsClass hook was removed with breaking change #63846 (https://docs.typo3.org/typo3cms/extensions/core/Changelog/7.5/Breaking-69568-FormEngine.html), even not in current master (as of 18-11-08), we currently use Reflection as a workaround.

E.g. to allow overriding 'eval'-config on an input tca field with TCEFORM.pages.lastUpdated.config.eval = required the following code placed in an extensions ext_localconf.php does the job for us:

    $reflectionClassFormEngineUtility = new ReflectionClass(\TYPO3\CMS\Backend\Form\Utility\FormEngineUtility::class);
    $reflectionPropertyAllowOverrideMatrix = $reflectionClassFormEngineUtility->getProperty('allowOverrideMatrix');
    $reflectionPropertyAllowOverrideMatrix->setAccessible(true); // make protected property accessible
    $allowOverrideMatrix = $reflectionPropertyAllowOverrideMatrix->getValue();
    $allowOverrideMatrix['input'][] = 'eval';
    $reflectionPropertyAllowOverrideMatrix->setValue($allowOverrideMatrix);

See also the $allowOverrideMatrix property in typo3/sysext/backend/Classes/Form/Utility/FormEngineUtility.php to see which array key is necessary to manipulate depending on your field type.

Tested with TYPO3 7.6.31 and PHP 5.6.

+1 from me on this. Would be very useful and increase flexibility. It would make it possible to make a filed required dependent on where in the page tree and which user is editing. I have a use case for that. O:-)
