PHP CodeIgniter 3 CRUD Application

This repository contains a comprehensive CRUD (Create, Read, Update, Delete) application developed using PHP and CodeIgniter 3.

It includes a HomeController, CrudController, CrudService, CrudRepository, and DatabaseModel, along with a Validation Helper and View Handling.

Features

  • MVC Architecture: Organized code structure for maintainability and scalability.
  • CRUD Operations: Perform Create, Read, Update, and Delete operations.
  • Session Management: Secure and efficient session handling.
  • Validation: Extensive form validation using CodeIgniter's form_validation.
  • Security: User passwords are stored using password_hash for enhanced security.
  • Unified Form: Registration and update are managed through a single form.
  • Exception Handling: Proper exception handling throughout the application.
  • Logging: Specific logging for tracking application behavior.
  • Code Commenting: Well-commented code for better understanding and maintainability.
  • Professional Project Structure: Adheres to professional standards for project creation and management.

CRUD Operations

  • Create: Add new records to the database.
  • Read: Retrieve and display records from the database.
  • Update: Modify existing records in the database.

Code Structure

  • Controllers: Handle incoming requests and interact with services.
    • HomeController: Manages the Login, Register, and Logout operations.
    • CrudController: Manages CRUD operations and interactions with services.
  • Libraries: Contain business logic and act as intermediaries between controllers and repositories.
    • CrudService: Handles the business logic for CRUD operations.
  • Models: Represent database entities and handle data operations.
    • CrudRepository: Mediator of CrudService and DatabaseModel, managing data persistence and retrieval.
    • DatabaseModel: Contains all database-related operations.
    • View Handler: Manages the presentation layer of the application.

    git clone https://github.com/SLoharkar/PHP-CodeIgniter-CRUD-Application.git
cd PHP-CodeIgniter-CRUD-Application

  2. Configure the database:

    • Create a database in MySQL.
    • Update the database configuration in application/config/database.php with your database credentials.

  3. Run the migrations:

    • Import the database.sql file located in the root of the project to your MySQL database. This will create the necessary tables.

  4. Configure the base URL:

    • Update the base URL in application/config/config.php to match your local or production environment.

  5. Start the application:

    • Place the project in the web root directory of your server (e.g., htdocs for XAMPP).
