Black Bar

Descrizione

Black Bar is an unobtrusive Debug Bar for WordPress developers that attaches itself to the bottom of the browser window. It is a rewrite of blackbox-debug-bar by Grzegorz Winiarski which appears to be abandoned as it has not been updated since 2013.

How it helps you with development:

  • Displays any PHP errors that occur when loading a page
  • Displays executed MySQL queries and the time it took to execute each query
  • Displays the loaded template files of the active theme
  • Inspect global variables (COOKIE, GET, POST, SERVER, SESSION)
  • Use the Console for debugging your plugins and themes
  • Use the Profiler for measuring the performance of your plugins and themes

FAQ

How do I add entries to the Console?

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

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

You can also add a specific 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, simply put the following line of PHP before and after the code you wish to profile:

apply_filters( 'profile', 'Enter a description of what you are profiling here' );
How do I restrict the plugin to logged-in administrators?

To restrict the plugin to logged-in administrators, use the following filter in your theme’s functions.php file:

/**
 * @return boolean
 */
add_filter( 'blackbar/enabled', function( $bool ) {
    $bool = is_user_logged_in()
        ? current_user_can( 'administrator' )
        : false;
    return $bool;
});

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.
