Conditional tag if an article has categories at all?

Hi! Apologies if this has been asked before, but I couldn’t find anything with a quick search…

In the default article form, the current article’s categories are displayed as <p class="tags"><txp:category1 title="1" link="1" />, <txp:category2 title="1" link="1" /></p>

However, if an article has no categories assigned, or only has one category, the comma still shows up.

Is there a way of testing how many categories have been assigned to an article, so the form can Do The Right Thing and not display a comma if is not necessary?

Thanks!

Conditional if_article_category tags can probably be arranged in such a way as to prevent the comma from appearing unless there is a second category assigned.

Thanks for the suggestion. However, I cannot seem to use txp:if_article_category to test for an empty category. Using <txp:if_article_category name=""> doesn’t work. I’m not sure what other value I could try.

I doubt the trick can be done using txp:if_article_category

For sure, it can be done using the plug-in chh_if_data (a must-to-have-installed txp plugin), or even easier, using jnm_categories

jnm_categories looks like exactly what I need! Thanks!!

I will also look at chh_if_data and see what else it can do for me :)

Cayse txp:if_article_category has attribute number, you can do:

<p class="tags">
	<txp:category1 title="1" link="1" />
	<txp:if_article_category number="2">
		, <txp:category2 title="1" link="1" />
	</txp:if_article_category>
</p>
