[TYPO3-ttnews] showRelatedNewsByCategory = 1 => sorted by category?

[Martin Holtz]

Hi,

i use
showRelatedNewsByCategory=1
and i want to show the news divided into categorys.

related news from category a:
-> item1
-> item2
-> item3

related news from category b:
-> item4
-> item5

related News from category c:
-> item6

i thougt i could use
orderBy = category
but the field "category" only counts how many categorys are related.

At this time, i was only able to implement this, with patching the function
displayList().

But i think, i am wrong and there should be an better way to do that?

Any hint? 

thanks,
martin

P.S.:
thats, what i have done

if ($this->config['orderBy']) {
        if (strtoupper($this->config['orderBy']) == 'RANDOM') {
                $selectConf['orderBy'] = 'RAND()';
        // this statement is new:
        // now, we have the first category which is assigned available
        // and we are able to sort by the category
        } elseif ($this->config['orderBy'] == 'category') {
                $selectConf['leftjoin'] = 'tt_news_cat_mm ON tt_news.uid =
tt_news_cat_mm.uid_local';
                $selectConf['selectFields'] = 'DISTINCT tt_news.uid,tt_news.*,
tt_news_cat_mm.uid_foreign';
                $selectConf['orderBy'] = ' tt_news_cat_mm.sorting asc,
tt_news_cat_mm.uid_foreign ';
                $selectConf['groupBy'] = 'tt_news_cat_mm.uid_local';
        } else {
                $selectConf['orderBy'] = $this->config['orderBy'] .
($this->config['ascDesc']?' ' . $this->config['ascDesc']:'');
        }
} else {
        $selectConf['orderBy'] = 'datetime DESC';
}
