Peek under the hood with sixty debugging reports just one click away.
For admins, developers, and support staff, Debug This provides a ton of information about your WordPress installation, all from the front-end admin bar.
Debug This helps you save time and effort when trying to figure out what’s going on. Instead of hardcoding debug snippets or writing complex unit
tests for small functionality, you can simply bring to the surface what you need right from the admin bar.
For example, when viewing a single post, you can see:
New debug modes can be created easily:
add_debug_extension( $mode, $menu_label, $description, $callback, $group = 'General' );
Example
add_debug_extension( 'actions', __('Actions', 'debug-this'), __('$wp_actions contains all active registered actions', 'debug-this'), 'foo_callback', 'Filters And Actions' ); function foo_callback($buffer, $template){ global $wp_actions; $debug = print_r($wp_actions, true); return $debug; }
You can add links to the header of a debug mode page. Place this code within your debug callback function.
add_debug_header_link('http://urltolink', 'Link Label');
Extensions can be removed as well using remove_debug_extension($mode);
No PRE Tags
If you don’t want your debug output to be enclosed in PRE tags, simply set the following in your extension:
Debug_This::$no_pre = true;
Saved Queries and Execution Time
Retrieve saved queries and execution time by using the following static properties:
Debug_This::$execution_time
Debug_This::$queries
– SAVEQUERIES must defined as trueURL Helpers
Debug_This::get_current_debug_url()
– current URL with the debug queryDebug_This::get_escape_url()
– used for the debug escape link that links to original page URLdebug_this
– receives the $mode arg – outputs the debug code sent from the extension modes. The default action is set to priority 5. This allows you to prepend or append any output without conflict using less or greater priorities.There are a few filters you can use to customize Debug This to your needs:
debug_this_template
– receives $template arg – Use your own templatedebug_this_default_mode
– receives $mode arg – Alters the mode for the parent DT admin bar button link.debug_this_output
– receives $output, $mode args – Filter debug content before it’s renderedTo access the built-in Debug This JS functionality, enqueue your custom script with the dependency set to debug-this
. Your script will inherit a jQuery dependency.
Object: debugThis
debugThis.mode
– current modedebugThis.defaultMode
debugThis.template
– current included templatedebugThis.queryVar
– the defined query string variableFunctions:
isDebug()
getDebugMode()
– uses isDebug()
Events:
A jQuery debug-this
event is fired from the footer. You can hook into this event with the following;
jQuery(document).bind('debug-this', function(event, debugThis){ console.log(debugThis); });
There are three included functions to help you work with files.
debug_this_get_file_ownership($file)
– returns array('name' => $name, 'group' => $group)
debug_this_get_file_perms($file)
– returns string – Example: 0775debug_this_convert_perms_to_rwx($perms)
– returns string – converts permission number to RWX format – Example: 0755 folder becomes drwxr-xr-xwp-content/plugins/
We’ve tested on PHP >= 5.2.17
Certainly! In order to keep the plugin lightweight and performant, requests that are too localized for the greater good may be refused. If that happens, I will gladly help you build your own debug mode.
Yes! Visit the Extend section to find out how you can thoroughly extend Debug This for your own needs.
