How to check if article_custom got results?

I need to check if the <txp:article_custom> tag returned results. Something like:

<txp:article_custom category="myCategory">
  If you have one or more articles
 <txp:else/>
  If you don't have articles
</txp:article_custom>

What is the easiest way to get there?

Re: How to check if article_custom got results?

Hi,
I’m sure that there is a more modern way using the evaluate tag but traditionally, you could try

<txp:variable name="hasarticles"><txp:article_custom category="myCategory" limit="1" /></txp:variable>
  <txp:if_variable name="hasarticles" value="">
      the category has no articles
  <txp:else/>
      It has articles
  </txp:if_variable>

Re: How to check if article_custom got results?

I just checked the docs. This may also work, although I have very limited experience with the tag:

<txp:evaluate test='<txp:article_custom category="myCategory" limit="1" />'>
    has articles
<txp:else />
    has no articles
</txp:evaluate>

alternatively:

<txp:evaluate test="myCategory">
    has articles
<txp:else />
    has no articles
</txp:evaluate>

I think that using this tag you can even delete the else statement and it will only return content if there is one.

What you suggest is working for me:

<txp:article_custom category="myCategory" limit="1">
  If you have one or more articles
 <txp:else />
  If you don't have articles
</txp:article_custom>

It is true! I should be doing something wrong initially. Thanks.

Thanks for the alternative ways, colak.
