Frequently Asked Questions
Common questions about Black Bar
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.
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');
By default, Black Bar is only visible to administrator users. To enable it for all logged-in users, use this code snippet: add_filter('blackbar/enabled', 'is_user_logged_in');
By default, Black Bar displays the 50 slowest action/filter hooks. To display all hooks, use this code snippet: add_filter('blackbar/hooks/all', '__return_true');
By default, Black Bar marks queries that run longer than 50ms with a warning color, and longer than 1000ms with an error color. To change these thresholds, use these hooks: add_filter('blackbar/queries/ms_error', fn () => 1000); // 1s add_filter('blackbar/queries/ms_warning', fn () => 50); // 50ms
