[TYPO3-dev] override or extend TCA by TypoScript

[Franz Holzinger]

Hello,

I think that it is necessary to be able to override the $TCA from 
tca.php or ext_tables.php by a user configurable TypoScript for a FE 
extension using $TCA.

'gender' => Array (
	'exclude' => 0,
	'label' => 'LLL:EXT:sr_feuser_register/locallang_db.xml:fe_users.gender',
	'config' => Array (
		'type' => 'radio',
		'items' => Array (
		 
Array('LLL:EXT:sr_feuser_register/locallang_db.xml:fe_users.gender.I.0', 
'0'),
		 
Array('LLL:EXT:sr_feuser_register/locallang_db.xml:fe_users.gender.I.1', 
'1'),
		 
Array('LLL:EXT:sr_feuser_register/locallang_db.xml:fe_users.gender.I.99', 
'99'),
		),
	)
),

Which syntax should this use?

E.g.

plugin.tx_srfeuserregister_pi1.tca.fe_users {
    column.gender.config.items {	 
LLL:EXT:sr_feuser_register/locallang_db.xml:fe_users.gender.I.0 = 0
		LLL:EXT:sr_feuser_register/locallang_db.xml:fe_users.gender.I.1 = 1
				LLL:EXT:sr_feuser_register/locallang_db.xml:fe_users.gender.I.99 = 99
     }
}

Or maybe:

plugin.tx_srfeuserregister_pi1.tcaOverrideFile = 
fileadmin/ext/sr_feuser_register/ext_tables_override.php

plugin.tx_srfeuserregister_pi1.tcaOverrideFile = 
EXT:sr_feuser_register/ext_tables_override.php

Then this file could be included to override e.g. the allowed items for 
the gender. In the future it shall be possible to not set the gender at 
all, so set it to empty or the value 99, However some sites will not 
want this. Therefore this must be made configurable somehow with 
TypoScript. Maybe only the backend shall allow a not set gender, and 
some registrations on the FE, too, but not all of them. Others might 
want to have a gender 'Fräulein'.
