How-to: checking not-empty tv...

Hi specialists, I’m not so skilled in php and a newb in modx. My Problem:
In my news articles I have

• the content for the full article
• a tv "teasertxt" for a short teaser with custom text different as the full article

Now I use ditto with custom tpl to list all news in an overview page. Some articles don’t need the content because they are only a short news on overview without a link to a full article.

How can I create tpl chunk/additional snippets to make this:

• If content is empty: show teasertxt
• if content AND teasertxt not empty: show teasertxt
• if content is not empty AND teasertxt is empty: show content

Any suggestions? thanks, Rainer

Ditto can use the document’s "summary" (introtext) as the default "teaser" text. Have you tried using that?

It’s difficult, because I want to build fully accessible pages (wcag, 508). Therefor I must have capabilities to set acronyms, lang-attr and so on. The summary isn’t flexible enough. That’s why I use a custom tv for teaser text. (Don’t know wether the introtext can have html? Otherwise this field is a bit too small to handle larger input.)

I use the summary field like this for a real estate listing page:

So not only can you use HTML, you can also use MODx tags in the summary field.

Use of HTML in summary was new knowlegde for me. Thanks for this, I’ll try it
