## Description

Add a Debug Bar to your WordPress website to debug and develop your themes, plugins,
etc…

With the plugin you can find every variables you want to debug in the same place
and use debug functions to display them.

#### Prerequisites

To fully help you to debug your website you need to add some code to your `wp-config.
php` file.

    ```
    define( 'WP_DEBUG', true ); // PHP errors, notices and warnings will be displayed
    define( 'SAVEQUERIES', true ); // Display queries in current page
    define( 'WP_DISABLE_FATAL_ERROR_HANDLER', true ); // Disable WP Fatal error handler
    ```

#### Usage of the debug functions

To debug a simple variable you can use:

    ```
    <?php dump( $var ); // Dump the variable(s) ?>
    ```

To debug a variable and stop the process after you can use:

    ```
    <?php dd( $var ); // This will die after dumping the variable(s) ?>
    ```

#### Debug a variable in the debug bar

This is one of the main aspect of the plugin, to debug variables in a separate place.

The most difficult task when you debug a variable is to deal with container width,
with the plugin you have a debug bar where you can add the variables of the current
page.

To add a variable to the debug bar you can use the function bellow:

    ```
    <?php kl_debug_add_var( $var ); ?>
    ```

You can add custom tabs in the debug bar to filter you variables:

    ```
    <?php
    kl_debug_add_var(
        $var, // The variable you want to debug
        'Your variable title', // If you want to name the variable
        'The section title', // The tab title
        'the-section-slug' // The tab slug
    );
    ?>
    ```

#### What’s Whoops in the setting panel?

Whoops is the framework that we use to display error handling. (cf. Pretty error
handler with stack frames)

## FAQ

### How to set which PHP errors are reported?

Simply add `error_reporting(E_ALL & ~E_NOTICE);` to the top of your theme functions.
php file. This will only display errors that are not notices.

Go to your FTP explorer and navigate to the plugin: wp-content>plugins. Rename the
folder by adding an _ in the beginning of the folder name.
