FAQ
-
Does this affect my site performance?
-
No! Hook Locator only runs in the WordPress admin when you actively search. There’s no frontend code or background processing that affects your site’s performance.
-
What file types does it search?
-
Hook Locator searches only PHP files (.php) since WordPress hooks are PHP-based. It automatically skips other file types for optimal performance.
-
Can I search for custom hooks?
-
Absolutely! Hook Locator finds any hook name you specify, including custom hooks created by plugins, themes, or your own code.
-
Is it safe to use on production sites?
-
Yes, Hook Locator is completely safe for production use. It only reads files and never modifies any code. All operations are restricted to users with administrator privileges.
-
Does it work with multisite?
-
Yes, Hook Locator works perfectly with WordPress multisite installations. Each site can use it independently to analyze their specific plugins and themes.
-
Can I export the search results?
-
Currently, you can copy individual code snippets to your clipboard. Future versions may include CSV/JSON export functionality based on user feedback.
-
What’s the difference from other hook plugins?
-
Hook Locator focuses on static code analysis rather than runtime hook capture. This makes it more accurate, secure, and performant while providing deeper code insights.
