[TYPO3-mvc] Howto: Manipulate override of settings (TS & Flexforms)

[Georg Ringer]

Hi,

maybe someone is interested in a little function I wrote in one of the
last days.

Proplem was:
There is an automatic override of configurations between Flexforms &
TypoScript. If TS states: settings.fo = 123 and there is a flexform
field settings.fo and left empty the result will be
$this->settings['fo'] => empty.

Additional information:
I know doing correct merging is not that simple because how can be
achieved to have no empty default values on the one hand but on the
other the possibility to make an option empty.

Solution:
I created a function injectConfigurationManager inside my controller,
get the merged configuration and the one from TS.
"settings.overrideFlexformSettingsIfEmpty" can be filled with a
commaseperated list of keys. For every key is checked: If its value is
empty in the final configuration it is overriden by the value of TS.

Comments are of course welcome
