详情介绍:

HookTrace is a developer observability tool that records and visualizes the runtime execution order of WordPress hooks, filters, and plugin initialization for a single page request. For Developers Only This plugin is designed exclusively for development and staging environments. It helps developers understand:

Which hooks fired, in what order
Which callbacks executed on each hook
Callback priority and execution time
Source plugin, theme, or core location
Exact file and line number
Plugin and theme load timeline

Key Features:

Hook List Tracking - Records all hooks that fire during a page request with type and source information
Detailed Callback Inspection - When a hook is selected, displays comprehensive callback information including priority, execution order, duration, file path, and source
Modern Modal UI - Beautiful, searchable interface with filtering capabilities
Zero Performance Impact - In-memory storage only, no database writes
Early Boot Support - MU-plugin bootstrap captures hooks from the very beginning

Requirements:

WP_DEBUG must be set to true in wp-config.php
User must have manage_options capability (administrator)
PHP 8.0 or higher

Safety Features:

Automatically disables when WP_DEBUG is false
Never runs for non-admin users
Never modifies WordPress behavior
Observational only - no code execution changes

安装:

Upload the hooktrace folder to /wp-content/plugins/ directory
Activate the plugin through the 'Plugins' menu in WordPress
Ensure WP_DEBUG is set to true in your wp-config.php file
(Optional) For early hook capture, copy hooktrace-bootstrap.php from the plugin directory to /wp-content/mu-plugins/

常见问题:

Does this plugin work in production?

No. This plugin is designed exclusively for development and staging environments. It requires WP_DEBUG to be enabled and will automatically disable itself if WP_DEBUG is false.

Will this slow down my site?

The plugin is designed with minimal overhead (5-10ms average). However, it should only be used in development/staging environments where performance is not critical.

Do I need to install the MU-plugin bootstrap?

The MU-plugin bootstrap is optional but recommended. It allows the plugin to capture hooks from the very beginning of WordPress initialization, including must-use plugins and early core hooks.

Can I use this to debug plugin conflicts?

Yes! The timeline view shows which hooks fire and which plugins are registering callbacks, making it easier to identify conflicts and execution order issues.

Does this modify WordPress behavior?

No. This plugin is purely observational. It never modifies hook execution, suppresses errors, or changes WordPress behavior in any way.

What data is stored?

No data is stored. All trace information is kept in memory for the current request only and is discarded after the page loads.

How do I inspect a specific hook?

Click on any hook in the list to see detailed information about all callbacks registered for that hook, including priority, execution order, duration, and source file location.
