PHP 8.4 “Undefined variable $groupby ” warning with txp:images
(because Homebrew was nagging I updated the local server)
PHP8.4.1, TXP 4.9-dev uptodate, debug mode.
Warning: Undefined variable $groupby Issue detected while parsing form None on page playgroundInput (in the <head />):
<if::article_image>
<txp:images>
<meta property="og:image" content="<image::url escape="html" />" />
<meta property="og:image:width" content="<image::info type="w" />" />
<meta property="og:image:height" content="<image::info type="h" />" />
<meta property="og:image:alt" content="<image::info type="alt" />" />
</txp:images>
</if::article_image>I also insert images in the body of the article with <txp:images /> which triggers the warning but that is nested in complex shortcode. The little block above is easier to parse.
On the admin side everything seems to hold fine with PHP 8.4, so far.
–^–
Edit
Noticed now, that test page is supposed to load two more images that are completely missing. With older PHP I thought I had a least a warning that the requested by the txp:shortcode was missing. The shortcode: <txp::pw_imageL id="30,25" />; the image with ID-30 is missing from the system.
This needs further testing

Re: PHP 8.4 “Undefined variable $groupby ” warning with txp:images
After reviewing and testing some more, this not really new nor any sort of “bug”. This can be reproduced with PHP 8.3. Every case that throws an error is because the requested image ID is missing from the DB and the associated image is not on the file system (anymore).
It is, in this case a very poorly formulated description for the issue at hand.
I don’t know if that can be improved from the Textpattern side or if that is a PHP issue.

A search for “Undefined variable $groupby” reveals some interesting results of mostly WP sites totally crashing.

We should guard against empty image results so this smells like a bug to me.

Could you post more diagnostics (line numbers) please? Can not reproduce on my side.

Here you go, sorry for forgetting that. This is for the sample given in the OP.
textpattern/vendors/Textpattern/Tag/Syntax/Image.php:389 parseList()
Textpattern\Tag\Syntax\Image::images()
textpattern/vendors/Textpattern/Tag/Registry.php:138 call_user_func()
textpattern/lib/txplib_publish.php:534 Textpattern\Tag\Registry->process()
textpattern/lib/txplib_publish.php:423 processTags()
textpattern/publish/taghandlers.php:1911 parse()
if_article_image()
textpattern/vendors/Textpattern/Tag/Registry.php:138 call_user_func()
textpattern/lib/txplib_publish.php:534 Textpattern\Tag\Registry->process()
textpattern/lib/txplib_publish.php:423 processTags()If that matters, article status is “Live”, not much special at all in the meta-data fields
