Problem/Motivation

A deprecated warning is triggered when adding a content item with URL-Alias in the form. If there is no URL-Pattern for this content type you get a deprecated warning. ONLY ON PHP 8.5!

Steps to reproduce

  1. Fresh DDEV setup
  2. PHP Version 8.5
  3. Drupal Version ~11.3.0
  4. Edit a content type with URL-Alias in the form BUT without a pattern.

Proposed resolution

Investigate and fix the deprecated warning caused by using a null value as an array offset in `PathautoGenerator`. Ensure that all array keys used for cached pattern lookups are normalized before access.

Remaining tasks

User interface changes

API changes

Data model changes

Can you give us a full reproducible scenario on a fresh Drupal instance please (Drupal version, PHP version, etc.)?

I haven't been able to reproduce the problem locally.

Could you eventually share the full stack trace of the warning you get?

Hey I can reproduce this using:
Fresh DDEV setup
PHP Version 8.5
Drupal Version ~11.3.0
Only installed Pathauto module

Edit a content type with URL-Alias in the form BUT without a pattern.

Full stack trace:

Deprecated function: Using null as an array offset is deprecated, use an empty string instead in Drupal\pathauto\PathautoGenerator->getPatternByEntity() (line 351 of /var/www/html/web/modules/contrib/pathauto/src/PathautoGenerator.php)

Hi, Tested on Drupal 11.2.3 with PHP 8.3.21 using a fresh DDEV setup and installed Pathauto module.

Followed the steps:
Content → Media → Add a media item. The media uploaded successfully, and no deprecated warning appeared.

Could you clarify if any additional setup is needed to reproduce this issue? Thanks.

Hi,

I had the same issue on php8.5 and pathauto 8.1.14, so I created a patch.

Is this issue possibly a duplicate of #3576435: PHP 8.5 deprecation?

@joegraduate
Since #3576435 is already closed we may need to fix this here.

This is almost certainly a duplicate. That was fixed recently and isn't released yet.

I installed version 1.15 of the module (I think this is the one that @berdir is referring to), but this error keeps happening.

Posted MR !173 as a sibling to !169 with a slightly different approach for the maintainers to choose from.

!169 fixes the symptom by coercing $entity->id() ?? 0 and $langcode ?: '', which makes the deprecation go away but caches every unsaved entity of a given type under the same [$entity_type_id][0] slot. !173 instead short-circuits at the top of getPatternByEntity() when $entity->isNew() and skips the per-id cache entirely for new entities — matching the intent that was already present in the existing if ($entity->isNew()) { return $pattern; } early return inside the loop. The language-override block is extracted into a small helper to avoid duplication between the two branches.

Both MRs make the PHP 8.5 deprecation go away; !173 removes it at the structural level rather than masking it with coercion, and avoids the shared-0-slot caching question for requests that build several unsaved entities of the same type (e.g. anywhere PathautoState::getValue() or PathautoWidget::formElement() is called).

Reviews welcome on either or both. Happy to fold ideas back into !169 or close !173 if !169 is preferred.

I can confirm that I’ve successfully reproduced the issue and that MR 173 resolves it.
