CodeIgniter Debug Toolbar

CodeIgniter Debug Toolbar is a functionality provided by the CI framework to help developers in debugging their applications. It is a lightweight extension that adds a debug bar to your website, allowing you to easily view and manage variables, logs, SQL queries, and other debugging information.

Introduction

The ciDebugBar object represents the main functionality of the CodeIgniter Debug Toolbar. It includes properties for the toolbar container, toolbar itself, and an icon. The init function initializes these properties and sets up listeners for events related to the toolbar.

Features

  • Variable Viewing: The Debug Toolbar allows developers to view and edit variables in real-time while debugging their application. This helps in identifying and fixing issues related to variable values.

  • Log Viewing: The toolbar displays log messages generated by your code. You can filter logs based on their severity level and search for specific log entries.

  • SQL Query Debugging: If you are using CodeIgniter with MySQL database, the Debug Toolbar provides an interface to view and execute SQL queries directly from the toolbar. This makes it easier to identify errors or inconsistencies in your database schema or queries.

  • Error Handling: The toolbar allows you to quickly navigate to specific error pages within your application, making it easier to diagnose and fix issues.

  • Navigation: The Debug Toolbar provides quick access to various sections of your application, such as controllers, models, views, and helper functions. This helps you to quickly switch between different parts of your application without having to scroll through your code.

Installation

To use the CodeIgniter Debug Toolbar, simply include the necessary files in your HTML layout file and initialize the ciDebugBar object in your index.php file. Here’s an example of how you can do it:
