Problem/Motivation

After updating the phone_international module to version 4.0.0, a "Warning: Undefined array key "#dial_code"" error is thrown on forms that use the phone field.

The full error trace is:

Warning: Undefined array key "#dial_code" in Drupal\phone_international\Element\PhoneInternationalElement::preRenderPhoneInternational() (line 125 of modules/contrib/phone_international/src/Element/PhoneInternationalElement.php).

This regression appears to be a side effect of the new dial-code functionality introduced in the 3bbc571a2e604e52153856e1871e6237186fc58f commit, which was part of issue 3460732 📌 Option to enable country dial code in the input field Needs review .

The root cause is that existing phone fields from before the 4.0.0 update do not have the new dial-code key in their configuration, causing the preRenderPhoneInternational() method to throw a warning.

Steps to reproduce

  1. Have a Drupal installation with the phone_international module installed on a version older than 4.0.0.
  2. Ensure there is an existing phone field configured on a content type or form.
  3. Update the phone_international module to version 4.0.0 using Composer.
  4. Navigate to a page that displays the phone field (e.g., a node add form or edit form).
  5. Observe the "Undefined array key" warning.

Proposed resolution

The issue can be resolved by providing a hook update that iterates over all existing phone_international fields and adds the new dial-code setting to their configuration, preventing the warning. This will ensure backward compatibility and a smooth upgrade path for existing sites.

Remaining tasks

  • Review the proposed resolution.
  • Create a patch that implements a new hook update function.
  • Test the patch to confirm the warning is resolved and that the field functionality remains intact.

User interface changes

None. This is a backend fix for a data model change.

API changes

None.

Data model changes

A hook update is required to modify the existing field configuration to add the new dial_code setting, preventing the "Undefined array key" warning.
