Black Bar

描述

Black Bar is an unobtrusive Debug Bar for WordPress developers. It collects and displays errors, executed SQL queries, slow actions and hooks, theme templates, global variables, and provides a profiler.

How it helps you with development:

  • Debug your code with the Console
  • Inspect global variables (COOKIE, GET, POST, SERVER, SESSION, WP_Screen)
  • Measure performance of your code with the Profiler
  • View any PHP errors that occur when loading a page in the Console
  • View executed MySQL queries along with execution time and backtrace
  • View template files of the active theme in loaded order
  • View the 50 slowest action and filter hooks along with callbacks ordered by priority

安裝

If you have never installed a WordPress plugin before, you can read instructions on how to do this here.

常見問題

How do I add entries to the Console?

To add entries to the console, insert the following line of PHP anywhere in your code:

apply_filters('console', 'Enter something to debug here');

You can also add an optional log level like this:

apply_filters('console', 'Enter something to debug here', 'error');

The available log levels are: debug, info, notice, warning, error, critical, alert, and emergency.

How do I use the Profiler?

To use the profiler, insert the following lines of PHP before and after the code you are profiling:

Before:

apply_filters('trace:start', 'Enter a description of what you are profiling here');

After:

apply_filters('trace:stop');

How do I enable the plugin for non-administrators?

By default, Black Bar is only visible to administrator users. To enable it for all logged-in users, add the following code to your child theme’s functions.php file:

add_filter('blackbar/enabled', 'is_user_logged_in');

Thank you for giving new life to BlackBox Debug Bar! Not only the usefulness of this plugin, but the beautiful PHP coding leads me to write this review. I have learnt a lot from your code.

This plugin can make life easier when a quick debug is needed. I use it specially to inspect what my $_GET, $_POST, $_SESSION, $_COOKIES variables look like.
