Cannot select tags in article on Joomla 4.3.4 with PHP version 8.1

[absillitoe]

Steps to reproduce the issue

With a lot of tags (I have between 200 and 300), when creating a new article or editing an existing one, and trying to assign a tag, the message "No results match" is received.

On Joomla 4, it is necessary to type the first few letters of a tag, and then those tags which correspond are displayed, allowing you to select one, However, with PHP 8.1,22 when typing a few letters of an existing tag, the message "No results match" is received.

Expected result

The corresponding tags should be displayed.

Actual result

The message "No results match" is received.

Additional comments

The problem goes away after reverting to PHP 8.0.30.

@absillitoe Can you please check if the fix of #41509 solves your problem?

[absillitoe]

@heelc29 I installed the patch tester, made and entered a Github token and fetched the data, but I don't seem to get patch #41509. What am I doing wrong?

[heelc29]

You're not doing anything wrong. The PR is already merged and therefore does not need any further human tests and is no longer available in the patch tester.
So now you have 3 other options:

• Update to 4.3.5 nightly build as the fix of [4.3] Tags: Don't put NULL into trim() #41509 will be released with 4.3.5 – not for production websites!
• Manually update the file components/com_tags/src/Controller/TagsController.php with the changes from [4.3] Tags: Don't put NULL into trim() #41509 ´
• Check your server logs if you see something like this PHP Deprecated: trim(): Passing null to parameter https://github.com/joomla/joomla-cms/pull/1 ($string) of type string is deprecated in C:\xampp\htdocs\joomla5\components\com_tags\src\Controller\TagsController.php on line 39 described in the issue [5.0] Deprecated: trim() ... when adding a tag in article #41466

Sorry for the delay. I cannot get my XAMPP installation to work since I updated it, so I have been able to use option 1. Not sure how to do option 2 correctly. I didn't see any error message when I looked, but perhaps I'm looking in the wrong place. Probably, your modification will fix my problem.

@heelc29 Finally managed to get my XAMPP working with PHP 8.1 and the tags seem to work fine on there. Do I need to do anything else?

[alikon]

if it is solved @absillitoe please close the issue

[heelc29]

You can close this issue and wait for the release of J4.3.5 (3 October 2023)
