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.

1

$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.

What is the concept of hooks in CodeIgniter on Hostinger?

In CodeIgniter on Hostinger, hooks are used to modify the core functionality of the framework without altering its source code. Hooks allow you to execute specific scripts or functions at predetermined points during the execution of the framework's processing.

Hooks can be used to perform tasks such as pre-processing, post-processing, modifying data, or running additional code before or after certain framework actions. They provide a way to tap into the framework's execution flow and extend its functionality according to your specific needs.

Hooks in CodeIgniter can be defined in the config/hooks.php file. This file contains an array of hook points, where you can specify the functions or scripts you want to execute. Each hook point has a name and an associated function or script to be executed.

When a hook point is reached during the framework's execution, CodeIgniter checks if any hooks are defined for that point and executes them accordingly. Hooks can modify input data, alter output, or perform any other desired operations within the defined hook function or script.

The concept of hooks allows for easy customization and extending the functionality of CodeIgniter without modifying the framework's core files. Rather than modifying the source code, you can define custom hooks and execute your code at specific points during the application's execution.

How to deploy a CodeIgniter application on Hostinger?

To deploy a CodeIgniter application on Hostinger, you can follow these steps:

1. Sign in to your Hostinger account and go to the Control Panel.
2. Under the Files section, click on File Manager.
3. In the File Manager, navigate to the public_html directory which is the root directory of your hosting account.
4. Delete all the files and folders inside the public_html directory, if any.
5. Click on the Upload button in the top toolbar and upload your CodeIgniter application files and folders. Make sure to include the application, system, and index.php files/folders.
6. Once the upload is complete, select the index.php file, right-click on it, and choose the Edit option.
7. In the index.php file, find the following lines of code:

1
2

$system_path = 'system';
$application_folder = 'application';

1. Update the values of $system_path and $application_folder variables to their respective paths relative to the public_html directory. For example, if the system and application folders are in the same directory as index.php, you can leave them as they are. If they are inside a folder named "ci", the code would be:

1
2

$system_path = 'ci/system';
$application_folder = 'ci/application';

1. Save the index.php file.
2. Your CodeIgniter application is now deployed. You can access it at your domain name (example.com) or IP address.

Note: Make sure your CodeIgniter application is compatible with the PHP version provided by Hostinger. You can change the PHP version in the Hostinger Control Panel under the 'PHP' section.
