Re: Specify article_custom limit AND check for non-empty custom field?

I was hoping to avoid having to assign a category, but it looks like this may be the only way for now (that doesn’t bog down the site, as Gocom pointed out).
Or try this plugin: no category required; not boggy.
Edit: Okay, having looked a little closer at Gocom’s post, I should qualify: not too boggy, at least not for most tastes. Does involve some extra queries, so not a solution if primo performance is a goal. But hardly noticeable in the context of a typical Txp install.

Wow!! You are fast – great documentation already in place too! I installed the plugin and it works beautifully. No noticeable bogginess as you predicted.
I’m a huge fan of your plugins and have soo_toc and soo_image installed as well. When are you adding a “Donate” button on your site? :)

Thanks, Jeff!
I was just about to gather my poor English and put up a plugin request. I had several sites where I could need exactly this. Each solved in the meantime, but I’m sure this here will get its chance!
In bad weather I never leave home without wet_plugout, smd_where_used and adi_form_links

artagesw’s solution is by far the simplest, but if you’re already using the categories for other things you’re stuck …
If you don’t want to burn categories for this, keywords provide another alternative.

Thanks alannie, very kind! I suppose if my plugin download rate and/or support thread traffic goes way up I’ll consider it, but for now I’m happy to share these plugins that I am finding useful myself. Of course, a donation to Txp is always welcome…

Re: Specify article_custom limit AND check for non-empty custom field?
Hmm, I’m taking the long way round to find a simple solution, as usual. Guess what:
<txp:article_custom limit="3" video_id="_%" />works. Might just have to mothball that plugin.

Re: Specify article_custom limit AND check for non-empty custom field?
^^ what?! _% works like a wildcard? do you know the explanation?
jsoo, thanks for sharing this discovery…

Re: Specify article_custom limit AND check for non-empty custom field?
See the ‘like’ function in MySQL, about a page down describes the wildcards. "%" is the equivalent of ".*" in PCRE syntax. "_" is the equivalent of ".". So "_%" is equivalent to ".+".

OMG, jsoo, you just started a whole new Txp era! Thank you :)

Re: Specify article_custom limit AND check for non-empty custom field?
Tread carefully there. That is likely an “unintended feature” that happens to work now but could break in the future. For one thing, it is MySQL-specific, which is something to watch out for if you want to maintain the flexibility of changing to a different database backend in the future.

Yes, some words from wet about this “unintented feature” could be helpful to know if it’s safe to use it in the long run.

Re: Specify article_custom limit AND check for non-empty custom field?
From a quick survey the same pattern (and the operator LIKE) will also work in SQLite and PostgreSQL.
Edit: And I wouldn’t call it “unintended”. It was certainly intended by whoever chose to use LIKE instead of =, as shown by the following comment in the function in question (buildCustomSql() in publish.php):
