README 

        
## Requirements



- PHP 5.5+ (recommended by CodeIgniter)

- CodeIgniter 3.1.x



## Installation



Create `composer.json` file in your application's root if there is none. Add the following text in the file: 

```json

{

    "require": {

        "tan5en5/codeigniter-debugbar": "dev-master"

    }

}

```

Enable Composer (locate in `application/config/config.php`) :

```php

$config['composer_autoload'] = realpath(APPPATH.'../vendor/autoload.php');

```

Enable Debugbar package (locate in `application/config/autoload.php`) :

```php

$autoload['packages'] = array(APPPATH.'third_party/codeigniter-debugbar');

```

if you want to log messages and exceptions you can also load console library

```php

$autoload['libraries'] = array('console');

```

To use it.

```php

$this->console->exception(new Exception('test exception'));

$this->console->debug('Debug message');

$this->console->info('Info message');

$this->console->warning('Warning message');

$this->console->error('Error message');

```

Then, enable the profiler like normal.

```php

$this->output->enable_profiler(TRUE);

```



To complete the installation, add the following header tags :

```html



```



## Configuration

**Duplicate** configuration file located in `application/third_party/codeigniter-debugbar/config/profiler.php` to `application/config/profiler.php`.



To configure the profiler, read [CodeIgniter profiler documentation](http://www.codeigniter.com/userguide3/general/profiling.html).



CodeIgniter Debug Bar adds 4 new sections :



- CodeIgniter infos : Display informations about CodeIgniter (version, environment and locale).

- Messages : Display messages (Console library must be loaded).

- Exceptions : Display exceptions (Console library must be loaded).

- Included files : Display included or required files.



You can configure PHP Debug Bar directly into the profiler configuration file, read [PHP Debug Bar documentation](http://phpdebugbar.com/docs/rendering.html#rendering) for more information.



## Advanced configuration



### AJAX



By default ajax debug data are send through headers but if you are sending a lot of data it may cause problems with your browser. If you set `open_handler_url` in the configuration file, it will use a storage handler and the open handler to load the data after an ajax request.



Here is an example of an `open_handler_url` setting.



```php

$config['open_handler_url'] = get_instance()->config->site_url('debug/open_handler');

```



This code will be in `application/controllers/Debug.php`



```php

output->enable_profiler(FALSE);

        $this->config->load('profiler', TRUE);

        $path = $this->config->item('cache_path', 'profiler');

        $cache_path = ($path === '') ? APPPATH.'cache/debugbar/' : $path;

        $debugbar = new DebugBar();

        $debugbar->setStorage(new FileStorage($cache_path));

        $openHandler = new OpenHandler($debugbar);

        $data = $openHandler->handle(NULL, FALSE, FALSE);



        $this->output

            ->set_content_type('application/json')

            ->set_output($data);

    }

}



```



### Output



There is two options that can be use to handle custom profiler output.



- `display_assets`: Whether display content's assets (default: TRUE)

- `display_javascript`: Whether display inline script (default: TRUE)



If you set `display_assets` to false you have to handle assets output manually, for this purpose you can use `CI_Profiler::css_assets()` and `CI_Profiler::js_assets()` they behave exactly like `JavascriptRenderer::dumpJsAssets()` and `JavascriptRenderer::dumpJsAssets()` see [PHP Debug Bar documentation](http://phpdebugbar.com/docs/rendering.html#assets) .



If you set `display_javascript` to false you have to handle inline script manually, for this purpose you can use `CI_Profiler::inline_script()` (**IMPORTANT** : It display inline script with <script> tags !).



Here is an exmple of how you can use it:



```php

output->get_content_type(), 'json') !== false)

        {

            echo $output;

            return;

        }



        if ($this->output->enable_profiler)

        {

            $this->appendAssets()

                ->appendBody('')

                ->appendBody('')

                ->appendHeader('')

                ->appendHeader('')

                ->appendInlineScript(trim(str_replace(['', ''], ['', ''], CI_Profiler::inline_script())));

        }



        echo $output;

    }



    /**

     * This method will write PhpDebugbar assets files if they don't exist in

     * public directory and add them to the output with custom functions.

     */

    protected function appendAssets()

    {

        $files = ['css_assets' => 'public/css/PhpDebugbar.css', 'js_assets' => 'public/js/PhpDebugbar.js'];



        foreach ($files as $function => $filepath)

        {

            if (!file_exists(FCPATH.$filepath))

            {

                forward_static_call_array(array('CI_Profiler', $function), array(FCPATH.$filepath));

            }

        }



        return $this->appendBody('')

            ->appendHeader('');

    }

```



**IMPORTANT** : Functions to handle profiler output can only be use in CodeIgniter controller function `_output()`.
