How to omit empty categories in list?

jonathanbrickman0000 · 2011-02-04 02:21:06

I’m using txp:category_list to list my categories — but I would like to make such a list, with empty categories omitted. Is there a way?

J.E.B.

Yes. You could use variables and article_custom to check if there is articles assigned to the category. Small example:

<txp:category_list>

	<!--
		Get the articles (if any) using article_custom
		and assign the results to a variable named "has_articles"
	-->

	<txp:variable name="has_articles"><txp:article_custom category='<txp:category />' limit="1">true</txp:article_custom></txp:variable>

	<!--
		Now check if there is anything
		inside the "has_articles" variable
	-->

	<txp:if_variable name="has_articles" value="">
		<txp:else />

			<!--
				If there is, we have an article,
				and we should show the category
			-->

			<txp:category title="1" link="1" />

	</txp:if_variable>

</txp:category_list>

should work like this

<txp:category_list categories=“category name(s) to display”> … your other code … </txp:category_list>

thx Gocom.
works fine for me, cause i also need the empty categories, for some other stuff.
so this was perfect, plus the list is fully automated and nobody has to work in the form.

gocom, this is great! as simple as possible, with good comments, one could not hope for more ;-)
