Update block parent handling for WP 6.8 compatibility

[jaakkolehtonen]

In WordPress 6.8, there was a change in how the Gutenberg block registration system handles the parent property. According to this forum thread, the parent property must now be either an array or undefined - passing null causes block registration to fail with the error: Uncaught TypeError: Cannot read properties of undefined (reading 'attributes')

Summary of Changes

This pull request addresses a compatibility issue with WordPress 6.8 related to how block parent properties are handled in the Gutenberg block registration system. The change ensures that the parent property is either an array or undefined, as passing null now causes block registration to fail. I've modified the Block.php file to accommodate this change.

Highlights

• WordPress 6.8 Compatibility: The code is updated to be compatible with the changes in WordPress 6.8 regarding Gutenberg block registration.
• Parent Property Handling: The parent property is now handled to ensure it's either an array or undefined, preventing block registration failures.

Changelog

• src/Block.php
  • Modified the register_block function to handle the parent property correctly.
  • Ensured that the parent property is only added to the $args array if it's not empty.
  • Moved the post_types assignment into a conditional block to mirror the parent property handling.
