How to make a condition to show description and keywords metatags only if their content is not empty?

F.e. I have a string

in my header chunk. How to make a condition to show this string only if content is not empty?
Same for description

Btw if it's matters description is a basic description field and keywords is custom TV parameter.

Try using



What this does is if the keywords TV is empty it will use the content TV as its value.

You can do this TV's, Placeholders and System/Context Settings as well.

Hope that helps. [ed. note: benmarte last edited this post 14 years, 7 months ago.]

You might be better of with something like:

[[*keywords:notempty=`<meta name="keywords" content="[[*keywords]]" />`]]

This would hide the keywords meta if none are present vs dumping the content into the keywords field which may hurt more than it helps.

If you look at MetaX 2.0 it takes an approach more along these lines.

I want to show metatag if field is not empty and show nothing if field has no content.
