Make a list of articles only if they have an article_image
Hello all,
I want to make a list of recent articles using a form but only the ones that have an article_image assigned.
- Article_custom is almost there with its customfield=“val” attribute, but an if attribute of the sort doesn’t exist for article_image.
- I looked through all plugins: articles, lists, conditionals, images… to no avail.
Is there a way to hack this? If_different? (i’m only throwing ideas here, i’ve been turning aroundf in circles over this one…)
thanks in advance

Try smd_if.

Els – how can smd_if check if article_image is assigned?
edemay – look through plugin iblastoff posted or look at ras_if_article_image – they are similar.
Here is an example of usage at my site:
<txp:ras_if_article_image>
<div class="image">
<txp:article_image thumbnail="1" />
</div>
<txp:else />
<!-- no image... -->

<txp:smd_if field="article_image" operator="isused">
// display it
<txp:else />
// don't
</txp:smd_if>@edemay : but I’d still go with iblastoff or the_ghost’s suggestion: they’re less resource intensive than smd_if for a single test; not to mention safer (and I just found a bug in the ‘defined’ check – rats!)

Re: Make a list of articles only if they have an article_image
Hey guys, thanks for the response, unfortunately, it only works half way. I had already tried it with chh_if_data:
in page:
<article_custom section="articles" limit="12" />
form:
<txp:chh_if_data>
<li><txp:permlink><txp:article_image /></txp:permlink></li>
</txp:chh_if_data>
It only outputs the article_images of the last 12 entries (if they exists, so 3 or 8 or 12 if its the case) and not the last 12 entries with article_images. Get the difference? I don’t want to give txp an alternative if its false, it has to display the article_images of the last 12 articles WITH an article_image assigned.
So that’s where i’m at. I feel like the hack has to be done from what the the article_custom calls. That’s why I mentionned the customfieldname="value" attribute of the article_custom tag. It would need a article_image="boolean" attribute. Is there any way to easily do this? (I’m totally php stupid btw).

Re: Make a list of articles only if they have an article_image
chh_if_data doesn’t work in your example (otherwise I would have suggested it to you), because you can only wrap it around one single txp tag. But why wouldn’t one of the abovementioned if_article_image plugins work?

Ah, yes, that won’t work because (if I remember correctly) you are testing the result of two tags in that code: txp:permlink and txp:article. Since txp:permlink always returns something (a href=“blah”) the chh_if_data will pass the test!
I would have thought that:
<txp:ras_if_article_image>
<txp:article />
</txp:ras_if_article_image>would have worked (or tcm_if_article_image of course). Not tested it but that’s how it’s supposed to work!

No I just took a typing course when I was still very young and now, finally, it’s paying off :)

Re: Make a list of articles only if they have an article_image
ok, ok. For the benefit of the doubt, I tried it with ras_if_article_image like you suggested but the result is the same: it only displays 8 images out of the wanted total of 12. Why? Because currently, the article tag calls to display the last 12 articles, THEN to display their article_image if they have one.
What I want, as I mentioned, is to display the article_images of the last 12 articles WITH an article_image assigned. Textpattern might have to go back 20, 40 or 50 articles in the past to display a total of 12 articles that do. Get it?

OT: Ahhh, genius. I can manage about 70wpm then have to go back and correct 67 of them for typos :-o Even the Mavis Beacon Typing Tutor software got fed up with telling me to “be proud of your success” and instead resorted to frosty silence when I blatantly couldn’t do it. *sigh*
Back on track: ok, sorry edemay I get it now. Yes, a conundrum indeed. article_custom’s limit is getting in the way and truncating your list. Hmmm… let me think…

Re: Make a list of articles only if they have an article_image
Just an idea: what if you first sort by the article_image field, then sort by date posted? In that case it would display the first 12 articles with an image, right? So:
<txp:article_custom sort="Image desc, Posted desc" limit="12" />(I am not sure if the image sort should be desc or asc – does it put empty fields first or last? – but you’ll find out soon enough.)
