Problem/Motivation

Seeing these errors on views page.

  • Notice: Undefined index: #options in Drupal\Core\Render\Element\Radios::processRadios() (line 62 of core/lib/Drupal/Core/Render/Element/Radios.php).
  • Warning: count(): Parameter must be an array or an object that implements Countable in Drupal\Core\Render\Element\Radios::processRadios() (line 62 of core/lib/Drupal/Core/Render/Element/Radios.php).

Steps to reproduce

Occuring on View with views_exposed_form using radio buttons.

Proposed resolution

If options are empty then it throws the warning - so check for empty before referencing the #options array index.

Fulll stack trace is

It’s a handy workaround, but what is the root cause?

I’m not exactly sure but like those other referenced issues the warnings only showed up after upgrades to drupal 9.4 and php7.4.

And its less of a work around than a safeguard. If for any reason there are no options then we don’t fail. The other issues were solved in a similar fashion.

Having this issue on Drupal 9.4.5 - 9.4.8 when we switched from PHP 7.4 to PHP 8.1

Version: 9.4.x-dev » 9.5.x-dev

Drupal 9.4.9 was released on December 7, 2022 and is the final full bugfix release for the Drupal 9.4.x series. Drupal 9.4.x will not receive any further development aside from security fixes. Drupal 9 bug reports should be targeted for the 9.5.x-dev branch from now on, and new development or disruptive changes should be targeted for the 10.1.x-dev branch. For more information see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

Confirmed this is still an issue in 10.0.9 when configuring your view settings.

After applying the patch, started receiving a 500 error on the page unfortunately.

Error from the logs;

TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in count() (line 62 of /var/www/docroot/core/lib/Drupal/Core/Render/Element/Radios.php).

This is duplicated of #3252288: Argument #1 ($value) must be of type Countable|array, null given in count() (line 57 of core/lib/Drupal/Core/Render/Element/Radios.php)..
