Hi,

I've got DOM working nicely, but I wondered is there a way to only show a few characters / first sentence of a returned field?

I've got three columns showing - date (date), author (text), and article content (html text) - and would like to just show the first few words of the article content as a summary, so that the table isn't huge!

I've had a look through the forum but can't see if anyone has managed to do this yet, or even requested it.

Cheers

In your headings array just use 'ArticleContent.FirstSentence' => 'Article Content (summary')

Thanks again for the quick reply, but I get:

Uncaught Exception: Object->__call(): the method 'newscontent' does not exist on 'NewsArticle'

when I try your suggestion (I called the field NewsContent instead of ArticleContent in the end).

This is the call I'm using that blows up:

$f->addFieldToTab("Root.Content.NewsArticles", new DataObjectManager(
         $this,
         'NewsArticles',
         'NewsArticle',
         array('Date' => 'Date','Author'=>'Author','NewsContent.FirstSentence' => 'NewsContent'),
         'getCMSFields_forPopup'
      ));

Cheers

Just do this

getShortNewsContent()
{
return $this->obj('NewsContent')->FirstSentence();
}

'ShortNewsContent' => 'Short news content'
