PCH: Fix potential fatal with 'enqueue_settings_assets' strict parameter

[vaurdan]

Description

Fix a potential fatal from happening, under some very specific scenarios, where the enqueue_settings_assets throws a fatal because it's expecting a string, and got a null instead.

Motivation and context

Improve the reliability of the WP Parse.ly codebase.

How has this been tested?

Tested locally, and validated that the styles and scripts are still being correctly enqueued.

Summary by CodeRabbit

• Bug Fixes
  • Improved stability of the settings page by handling potential null values in settings assets.

Walkthrough

Walkthrough

The functionality change in the enqueue_settings_assets method within src/UI/class-settings-page.php involves adjusting the type of the $hook_suffix parameter from string to ?string. This change is accompanied by a new null check to ensure $hook_suffix is not null before further processing. This update aims to enhance the method's robustness by handling potential null values.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

163-165: Ensure the null check is consistent with the parameter type.

The null check for $hook_suffix is appropriate given the updated parameter type. This improves the function's robustness by preventing potential fatal errors.
