Message if no articles in category
Can’t quite find what I am looking for – I need to display a message to say something like “Sorry, no articles in this category” if there are no articles within that category.
Code:
<txp:if_category>
<h3>All articles in the <txp:category title="1" link="1" /> category.</h3>
<txp:article form="classifieds_list" limit="100" />
<txp:else />
<txp:article form="classifieds_list" limit="5" />
</txp:if_category>The code above outputs the message “All articles in the —— category.” That’s fine, but no good if there are no articles. Anyone know of a plugin for this?

Can chh_if_data help?

Yeah I saw that, and pm_if_article, but not got them working the way I want yet.

Re: Message if no articles in category
Aha, yes, it’ll probably require a slight change in your logic because, regardless if there any articles or not, the txp:category tag will return ‘true’ thus always executing the first part.
You could get round it like this:
<txp:if_category>
<h3>Articles in the <txp:category title="1" link="1" /> category</h3>
<txp:chh_if_data>
<txp:article form="classifieds_list" limit="100" />
<txp:else />
<p>Sorry, no articles found.</p>
</txp:chh_if_data>
<txp:else />
<txp:article form="classifieds_list" limit="5" />
</txp:if_category>Any good? Or -swf_if_empty dang, colak beat me to it.

Re: Message if no articles in category
Thanks guys. Almost there. Funnily enough, I had just downloaded chh_if_data to test it out. I have not heard of swf_if_empty – if this does not work, I will try that.
Currently:
<txp:if_category>
<txp:chh_if_data>
<h3>All articles in the <txp:category title="1" link="1" /> category</h3>
<txp:article form="classifieds_list" limit="100" />
<txp:else />
<h3>Sorry, no articles in the <txp:category title="1" /> category.</h3>
</txp:chh_if_data>
<txp:else />
<txp:article form="classifieds_list" limit="5" />
</txp:if_category>Hmm. In the category page where there are no articles, I still get: “All articles in the ….. category”. Pain in the ###!

You will do. You have 2 TXP tags surrounded by the chh_if_data and else tags (namely txp:category and txp:article). It tests them both. txp:article will return nothing as it should but txp:category returns the category name, thus chh_if_data thinks “aha, some output” and will display the first part, NOT the else as you expect.
Took me a while to figure that out when I first used it; confused the heck out of me. See my post above for a (possible) way round it.

Re: Message if no articles in category
Thanks Stef. I will go with your code for now – I do get a proper error message like this:
“All articles in the …. category:
Sorry, no classifieds found in this category.”
So, no way around this that you know of? Would be nice to get rid of the “All articles in the … category:” part, since there aren’t any. I am a perfectionist ;-)

Re: Message if no articles in category
I should also own up: That was not the complete code, I had a bit more:
<txp:if_article_list>
<txp:if_section name="articles">
<txp:if_category>
<h3>All articles in the <txp:category title="1" link="1" /> category:</h3>
<txp:chh_if_data>
<txp:article form="classifieds_list" limit="100" />
<txp:else />
<p>Sorry, no articles found in this category.</p>
</txp:chh_if_data>
<txp:else />
<txp:article form="classifieds_list" limit="5" />
<txp:ob1_pagination firsttext="First page" previoustext="Previous page" nexttext="Next page" lasttext="Last page" ulclass="pagination" />
</txp:if_category>
</txp:if_section>
</txp:if_article_list>Edit: Placed the code here for completeness.

Hehehe, not unless you reword the h3 or put the <txp:category /> outside the chh_if_data somehow, sorry.
However, I’m not sure what would happen if you used:
<txp:chh_if_data>
<h3>All articles in the <txp:php>echo category(array("title" => "1", "link" => "1"));</txp:php> category</h3>
<txp:article form="classifieds_list" limit="100" />
<txp:else />
<h3>Sorry, no articles in the <txp:category title="1" /> category.</h3>
</txp:chh_if_data>chh_if_data may just look at the “return value” of the txp:php call, which could well be nada in this case. EDIT: it doesn’t, it reads the result of the contents of the PHP call, so this method won’t work. Humbug.
