CakePHP DebugKit

DebugKit provides a debugging toolbar and enhanced debugging tools for CakePHP applications., _(*1)

Requirements

The master branch has the following requirements:, _(*2)

CakePHP 2.2.0 or greater.
PHP 5.3.0 or greater.

Installation

Using Composer, _(*3)

Install the plugin with Composer from the directory, where your project's composer.json is located:, _(*4)

php composer.phar require cakephp/debug_kit "^2.2.0"

Consider using "--dev", if you only want to include DebugKit for your development environment., _(*5)

Because this plugin has the type cakephp-plugin set in it's own composer.json, composer knows to install it inside your /Plugin directory, rather than in the usual vendors file. It is recommended that you add /Plugin/DebugKit to your .gitignore file. (Why? read this.), _(*6)

[Manual], _(*7)

Download the DebugKit archive.
Unzip that download.
Rename the resulting folder to DebugKit
Then copy this folder into app/Plugin/

[GIT Submodule], _(*8)

In your app directory type:, _(*9)

git submodule add --branch 2.2 git://github.com/cakephp/debug_kit.git Plugin/DebugKit
git submodule init
git submodule update

[GIT Clone], _(*10)

In your plugin directory type, _(*11)

git clone --single-branch --branch 2.2 git://github.com/cakephp/debug_kit.git DebugKit

Enable plugin

In 2.x, you need to enable the plugin in your app/Config/bootstrap.php file. If you are already using CakePlugin::loadAll();, then the following is not necessary.:

    CakePlugin::load('DebugKit');

Include the toolbar component in your app/Controller/AppController.php:

class AppController extends Controller {
         public $components = array('DebugKit.Toolbar');
}

Set Configure::write('debug', 1); in app/Config/core.php.
Make sure to remove the 'sql_dump' element from your layout (usually app/View/Layouts/default.ctp), if you want to experience the awesome that is the DebugKit SQL log.

Reporting Issues

If you have a problem with DebugKit please open an issue on GitHub., _(*12)

Contributing

If you'd like to contribute to DebugKit, check out the roadmap for any planned features. You can fork the project, add features, and send pull requests or open issues., _(*13)

Versions

DebugKit has several releases, each compatible with different releases of CakePHP. Use the appropriate version by downloading a tag, or checking out the correct branch., _(*14)

1.0, 1.1, 1.2 are compatible with CakePHP 1.2.x. These releases of DebugKit will not work with CakePHP 1.3. You can also use the 1.2-branch for the mos recent updates and bugfixes.
1.3.0 is compatible with CakePHP 1.3.x only. It will not work with CakePHP 1.2. You can also use the 1.3 branch to get the most recent updates and bugfixes.
2.0.0 is compatible with CakePHP 2.0.x only. It will not work with previous CakePHP versions.
2.2.0 is compatible with CakePHP 2.2.0 and greater. It will not work with older versions of CakePHP as this release uses new API's available in 2.2.
2.2.x are compatible with CakePHP 2.2.0 and greater. It is a necessary upgrade for people using CakePHP 2.4 as the naming conventions around loggers changed in that release.
3.x.x are compatible with CakePHP 3.0.0 and greater. These versions are developed in the master branch.

Documentation

The DebugKit Toolbar is comprised of several panels, which are shown by clicking the CakePHP icon in the upper right-hand corner of your browser after DebugKit has been installed and loaded. Each panel is comprised of a panel class and view element. Typically, a panel handles the collection and display of a single type of information such as Logs or Request information. You can choose to panels from the toolbar or add your own custom panels., _(*15)

Built-in Panels

There are several built-in panels, they are:, _(*16)

History Allows access to previous request information, useful when debugging actions with redirects.
Request Displays information about the current request, GET, POST, Cake Parameters, Current Route information and Cookies if the CookieComponent is in you controller's components.
Session Display the information currently in the Session.
Timer Display any timers that were set during the request see DebugKitDebugger for more information. Also displays memory use at component callbacks as well as peak memory used.
Sql Logs Displays sql logs for each database connection.
Log Display any entries made to the log files this request.
Variables Display View variables set in controller.
Environment Display environment variables related to PHP + CakePHP.

Configuration

The toolbar has a few configuration settings. Settings are passed in the component declaration like normal component configuration., _(*17)

public $components = array(
    'DebugKit.Toolbar' => array(/* array of settings */)
);

Configuring Panels

You can customize the toolbar to show your custom panels or hide any built-in panel when adding it toolbar to your components., _(*18)

public $components = array('DebugKit.Toolbar' => array(
    'panels' => array('MyCustom', 'timer'=>false)
    )
);

Would display your custom panel and all built-in panels except the 'Timer' panel., _(*19)

Controlling Panels

Using the panels key you can specify which panels you want to load, as well as the order in which you want the panels loaded., _(*20)

public $components = array(
        'DebugKit.Toolbar' => array('panels' => array('MyCustom', 'timer' => false))
);

Would add your custom panel MyCustomPanel to the toolbar and exclude the default Timer panel. In addition to choosing which panels you want, you can pass options into the __construct of the panels. For example the built-in History panel uses the history key to set the number of historical requests to track., _(*21)

public $components = array(
        'DebugKit.Toolbar' => array('history' => 10)
);

Would load the History panel and set its history level to 10. The panels key is not passed to the Panel constructor., _(*22)

forceEnable

The forceEnable setting is new in DebugKit 1.1. It allows you to force the toolbar to display regardless of the value of Configure::read('debug');. This is useful when profiling an application with debug kit as you can enable the toolbar even when running the application in production mode., _(*23)

autoRun

autoRun is a new configuration setting for DebugKit 1.2. It allows you to control whether or not the toolbar is displayed automatically or whether you would like to use a query string parameter to enable it. Set this configuration key to false to use query string parameter toggling of the toolbar., _(*24)

public $components = array(
    'DebugKit.Toolbar' => array('autoRun' => false)
);

When visiting a page you can add ?debug=true to the url and the toolbar will be visible. Otherwise it will stay hidden and not execute., _(*25)

Developing Your Own Panels

You can create your own custom panels for DebugKit to help in debugging your applications., _(*26)

Panel Classes

Panel Classes simply need to be placed inPanel directory inside a Lib path. The filename should match the classname, so the class MyCustomPanel would be expected to have a filename of app/Lib/Panel/MyCustomPanel.php., _(*27)


App::uses('DebugPanel', 'DebugKit.Lib');

/**
 * My Custom Panel
 */
class MyCustomPanel extends DebugPanel {
        ...
}

See also the example Test/test_app/Plugin/DebugkitTestPlugin/Lib/Panel/PluginTestPanel.php., _(*28)

Notice that custom panels are required to subclass the DebugPanel class. Panels can define the css and javascript properties to include additional CSS or javascript on the page. Both properties should be an array., _(*29)

class MyCustomPanel extends DebugPanel {
        public $javascript = array(
                '/my_plugin/js/custom_panel.js'
        );
}

Callbacks

Panel objects have 2 callbacks, that allow them to hook into and introspect on the current request., _(*30)

startup(Controller $controller)

Each panel's startup() method is called during component startup() process. $controller is a reference to the current controller object., _(*31)

beforeRender(Controller $controller)

Much like startup() beforeRender() is called during the Component beforeRender() process. Again $controller is a reference to the current controller. Normally at this point you could do additional introspection on the controller. The return of a panels beforeRender() is automatically passed to the View by the Toolbar Component. Therefore, under normal use you do not need to explicitly set variables to the controller., _(*32)

Example of beforeRender Callback

/**
 * beforeRender callback - grabs request params
 *
 * @return array
 */
 public function beforeRender(Controller $controller) {
     return $controller->params;
 }

This would return cake's internal params array. The return of a panel's beforeRender() is available in you Panel element as $content, _(*33)

Panel Elements

Each Panel is expected to have a view element that renders the content from the panel. The element name must be the underscored inflection of the class name. For example SessionPanel has an element named session_panel.ctp, and sqllogPanel has an element named sqllog_panel.ctp. These elements should be located in the root of your View/Elements directory., _(*34)

Custom Titles and Elements

Panels should pick up their title and element name by convention. However, if you need to choose a custom element name or title, there are properties to allow that configuration., _(*35)

$title - Set a custom title for use in the toolbar. This title will be used as the panels button.
$elementName - Set a custom element name to be used to render the panel.

Panels as Cake Plugins

Panels provided by Cake Plugins work almost entirely the same as other plugins, with one minor difference: You must set public $plugin to be the name of the plugin directory, so that the panel's Elements can be located at render time., _(*36)

class MyCustomPanel extends DebugPanel {
    public $plugin = 'MyPlugin';
        ...
}

To use a plugin panel, use the common CakePHP dot notation for plugins., _(*37)

public $components = array('DebugKit.Toolbar' => array(
    'panels' => array('MyPlugin.MyCustom')
));

The above would load all the default panels as well as the custom panel from MyPlugin., _(*38)

Cache Engine

By default, DebugKit uses File as the engine for internal caching, but if you want to use another cache engine you can customize it by simply adding a cache key inside the components config array., _(*39)

public $components = array('DebugKit.Toolbar' => array(
        'cache' => array('engine' => 'Memcache', 'servers' => array('127.0.0.1:11211'))
        )
);

You can use any cache engine supported by CakePHP, the same way you set in both core.php and bootstrap.php files with the Cache::config() method., _(*40)

When doing AJAX requests, you will not be able to see an HTML version of the toolbar. However, if you have a browser extension that supports FirePHP, you can view the toolbar in your browser:, _(*41)

Once you have installed the correct extension, you should see the toolbar data output on each AJAX request., _(*42)
