TYPO3：$ TCA数组['types'] [key]部分

Question

I want to know what ; and the numbers 2-2-2 in this array means

'types' => Array (
        '0' => Array('showitem' =>
            'hidden, type;;;;1-1-1,title;;;;2-2-2,short,bodytext;;2;richtext:rte_transform[flag=rte_enabled|mode=ts];4-4-4,
            --div--;LLL:EXT:tt_news/locallang_tca.xml:tt_news.tabs.special, datetime;;;;2-2-2,archivedate,author;;3;; ;;;;2-2-2,
                keywords;;;;2-2-2,sys_language_uid;;1;;3-3-3,
            --div--;LLL:EXT:tt_news/locallang_tca.xml:tt_news.tabs.media, image;;;;1-1-1,imagecaption;;5;;,links;;;;2-2-2,news_files;;;;4-4-4,
            --div--;LLL:EXT:tt_news/locallang_tca.xml:tt_news.tabs.catAndRels, category;;;;3-3-3,related;;;;3-3-3,
            --div--;LLL:EXT:tt_news/locallang_tca.xml:tt_news.tabs.access, starttime,endtime,fe_group,editlock,
            --div--;LLL:EXT:tt_news/locallang_tca.xml:tt_news.tabs.extended,
            '),

The reason is I want to add a group behind "news_files". Link to TCA reference .

Answer 1

showitem consists of fields separated by commas ( , ). Each field is defined by 1-5 arguments separated by semicolons ( ; ). The first (mandatory) argument is the field name that can be followed by another 4 extra arguments. The last argument that you are referring to ("2-2-2") is a form style code which is divided by a hyphen ( - ) into colorscheme , stylescheme and borderscheme .
