Can <txp:images> remain unsorted?

nabrown78 · 2011-03-03 16:59:38

Hi All, I would like to output images based on an article’s Article Image field using <txp:images /> like so:

<ul class="thumbnails clearfix">
<txp:images break="">
  <li><a href="<txp:image_url />" class="<txp:image_info type="w" />x<txp:image_info type="h" />"><txp:thumbnail /></a></li>
</txp:images>

This is in an <txp:article /> context. The thing is, I’ve listed the image ID’s in the exact order I want them output, but <txp:images /> sorts them. Is there any way I can leave them unsorted, preserving the order I’ve specified?

Thanks.

Oops! Nevermind. I guess I’d like to be able to do this with native txp tags, but the excellent soo_image does the job.

I use this method, seems a little hacky but it is not really:

<txp:images id='<txp:custom_field name="article_image" />'  wraptag="ul" break="li" sort=' field(id, <txp:custom_field name=''article_image'' />)'>

Edit: Er… too late

Aha! Well, that would do the job without a plugin. Thanks for the help redbot!

Thaaat’s cool! I was struggling with this some weeks ago and didn’t think of the SQL-sorting method. Thanks, Luca! :)

You are welcome Uli.
BTW, we have to thank Bloke for the clever txp:custom_field name="article_image" trick.

Time out — does that mean that <txp:custom_field name="article_image" /> outputs what is actually in the article image field (that would be interesting)? Or do you have to create an actual custom field called that?

Nora, I just posted a new TXP Tip on how to display the first image from a list in the article image field to help answer your question.

As redbot indicates, the trick is courtesy of the ever wonderful Stef Dawson.

No, that’s not necessary. BTW, Textpattern outputs a lot more data fields if they’re queried by a custom_field/if_custom_field tag.

Very cool — I left a comment, with a questions, on that page (and actually, if it’s not too much of a PITA, can you edit my url to be www.norabrowndesign.com, instead I have a comma in there somehow).

Yes, Uli is right. That’t because if you examine the “custom_field” function as defined in taghandlers.php you’ll realize that any value you pass it as the tag attribute ‘name’ will be then used to fetch a specific raw value from the $thisarticle array.
In other words <txp:custom_field name = "article_image" /> is quite the same that

<txp:php>
echo $thisarticle['article_image'];
</txp:php>

In the same vein if you write:

<txp:custom_field name = "authorid" />

You should get the author of the currently viewed article.

I hope it’s clear enough.

This is verging on a ‘bug’ insofar as the function name implies that you should only be able to retrieve custom field data, but as redbot says you can actually get any article field.

Most of $thisarticle is queryable using dedicated tags, but <txp:article_image /> is the exception because it formats the data before output. So this trick is actually pretty handy and I’d be loathe to lose it because it fills a gap in the function suite. Maybe if the article_image tag is modded one day to allow it to output its raw value then this loophole can be closed. But not before: it’s too useful!
