What is the Model-View-Controller (MVC) pattern in CodeIgniter on Hostinger?

The Model-View-Controller (MVC) pattern is a software design pattern used in web development to separate the application logic into three interconnected components: the Model, the View, and the Controller.

In the context of CodeIgniter on Hostinger, MVC is the default architecture followed by CodeIgniter framework. Here's how the pattern is implemented in CodeIgniter:

1. Model: The Model represents the data and database interactions of the application. In CodeIgniter, models are stored in the application/models directory. Models contain functions to retrieve, insert, update, and delete data from the database.
2. View: The View represents the presentation layer of the application, responsible for rendering the user interface. In CodeIgniter, views are stored in the application/views directory. Views contain HTML, CSS, and optionally PHP code to display data fetched from the model.
3. Controller: The Controller acts as the intermediary between the Model and the View, handling user requests and updating the model or view accordingly. In CodeIgniter, controllers are stored in the application/controllers directory. Controllers contain functions (called methods) that respond to different user actions and load the appropriate views and models.

CodeIgniter's routing system directs incoming requests to the appropriate controller and method, following the MVC pattern. Controllers access data from models, process it, and pass it to the corresponding view for display.

Using the MVC pattern in CodeIgniter on Hostinger helps to maintain a structured and organized application by separating concerns and promoting code reusability.

How to handle errors and logging in CodeIgniter on Hostinger?

To handle errors and logging in CodeIgniter on Hostinger, you can follow these steps:

1. Enable error logging in the CodeIgniter configuration file. Open the application/config/config.php file and set the log_threshold value to the desired level of logging. For example, you can set it to 2 to log all errors and messages.

$config['log_threshold'] = 2;

1. Set the log file path. By default, CodeIgniter logs its messages in the application/logs directory. Make sure this directory is writable by the web server. If the directory doesn't exist, create it manually.
2. Enable error logging in the Hostinger control panel. Log in to your Hostinger control panel and navigate to the Error Logging section. Enable error logging for your website.
3. Check the error logs. Once enabled, error logs will be generated in the application/logs directory. You can access these logs through the Hostinger control panel or directly via FTP.
4. Use built-in logging functions. CodeIgniter provides built-in logging functions that you can use throughout your application. For example:

• log_message('error', 'This is an error message'); logs an error message.
• log_message('debug', 'This is a debug message'); logs a debug message.
• show_error('This is a custom error message'); displays a custom error message.

By following these steps, you will be able to handle errors and log messages effectively in CodeIgniter on Hostinger.
