Pretty Print for objects

- Basic
- Request (optional)
- Admin (for admin side only)
- Query (for frontend only)
- Content (optional)
- Roles (optional)
- Constants (optional)

- AJAX (if AJAX calls are captured while page is active)
- Store (if there are user stored objects to show)
- Tools (internal and external tools links)
- Debug Log (load content on demand from WordPress ‘debug.log’)
SQL Queries
This panel lists all the queries WordPress has run, and it allows you to order the queries by execution order or length of execution, and all queries can be filtered by the query type, database table it targets or the WordPress function that called it. Every query displays the execution time, order, caller functions stack and fully formatted SQL query that is easy to read.
PHP and WordPress Errors
Plugin has 3 panels dedicated to showing PHP and WordPress errors and warnings. Plugin captures this information during the page load, and it shows full debug trace as returned by the PHP debug tracing function.
AJAX
The plugin tracks every AJAX call coming through WordPress admin-ajax.php handler, and with every response, it returns HTTP headers with AJAX request basic execution information. Right now, plugin is not returning list of logged errors or SQL queries, because both can produce huge output that goes over the HTTP header limits. Plan is to introduce these in the future plugin versions.
Info Panels
In the administration Tools menu, plugin adds DebugPress Info page showing several panels
- PHP Info: full formatted results from
phpinfo() function
- OPCache Info: full settings and statistics for the OPCache PHP extension
- MySQL Variables: full MySQL settings retrieved from the database
Plugin Settings
The plugin has various options controlling the plugin activation, button integration position, user roles that can see the debugger window, options to attempt overriding WordPress debug flags and options controlling the visibility of optional debugger panels.
