# CodeIgniter 4 Application Starter

## What is CodeIgniter?

CodeIgniter is a PHP full-stack web framework that is light, fast, flexible and secure.
More information can be found at the [official site](https://codeigniter.com).

This repository holds a composer-installable app starter.
It has been built from the
[development repository](https://github.com/codeigniter4/CodeIgniter4).

More information about the plans for version 4 can be found in [CodeIgniter 4](https://forum.codeigniter.com/forumdisplay.php?fid=28) on the forums.

You can read the [user guide](https://codeigniter.com/user_guide/)
corresponding to the latest version of the framework.

## Installation & updates

`composer create-project codeigniter4/appstarter` then `composer update` whenever
there is a new release of the framework.

When updating, check the release notes to see if there are any changes you might need to apply
to your `app` folder. The affected files can be copied or merged from
`vendor/codeigniter4/framework/app`.

## Setup

Copy `env` to `.env` and tailor for your app, specifically the baseURL
and any database settings.

## Important Change with index.php

`index.php` is no longer in the root of the project! It has been moved inside the *public* folder,
for better security and separation of components.

This means that you should configure your web server to "point" to your project's *public* folder, and
not to the project root. A better practice would be to configure a virtual host to point there. A poor practice would be to point your web server to the project root and expect to enter *public/...*, as the rest of your logic and the
framework are exposed.

**Please** read the user guide for a better explanation of how CI4 works!

## Repository Management

We use GitHub issues, in our main repository, to track **BUGS** and to track approved **DEVELOPMENT** work packages.
We use our [forum](http://forum.codeigniter.com) to provide SUPPORT and to discuss
FEATURE REQUESTS.

This repository is a "distribution" one, built by our release preparation script.
Problems with it can be raised on our forum, or as issues in the main repository.

## Server Requirements

PHP version 8.1 or higher is required, with the following extensions installed:

- [intl](http://php.net/manual/en/intl.requirements.php)
- [mbstring](http://php.net/manual/en/mbstring.installation.php)

> [!WARNING]
> - The end of life date for PHP 7.4 was November 28, 2022.
> - The end of life date for PHP 8.0 was November 26, 2023.
> - If you are still using PHP 7.4 or 8.0, you should upgrade immediately.
> - The end of life date for PHP 8.1 will be December 31, 2025.

Additionally, make sure that the following extensions are enabled in your PHP:

- json (enabled by default - don't turn it off)
- [mysqlnd](http://php.net/manual/en/mysqlnd.install.php) if you plan to use MySQL
- [libcurl](http://php.net/manual/en/curl.requirements.php) if you plan to use the HTTP\CURLRequest library

## Slip Printer Configuration

The late-slip printer can be configured via `.env`. The controller supports both uppercase `PRINTER_*` keys and dotted `printer.*` keys.

- `PRINTER_MODE` or `printer.mode`: `network` (default), `usb`, or `windows`
  - Special: `disabled`/`off`/`none` skips device printing (useful in test)
- `PRINTER_HOST` / `PRINTER_PORT` or `printer.host` / `printer.port`: Network printer TCP settings
- `PRINTER_USB_VID` / `PRINTER_USB_PID` or `printer.usb.vid` / `printer.usb.pid`: USB printer identifiers (Linux/Mac)
- `PRINTER_WINDOWS_NAME` or `printer.windows.name`: Windows printer share/port name (Windows only)
- `PRINTER_CHARS_PER_LINE` or `printer.chars_per_line`: Characters per line (80mm paper ≈ 48–56)
- `PRINTER_FEED_LINES` or `printer.feed_lines`: Number of trailing blank lines before cut

Notes:
- When `PRINTER_MODE=windows` is set on a non-Windows OS, the app falls back to `network` mode.
- USB mode on Linux/Mac requires both VID and PID values.

## Testing

The PHPUnit suite expects a real database connection so it can apply migrations and seed data from `tests/_support/Database`. Tests will use the `tests` database group defined in `app/Config/Database.php`, which already points to `localhost` and the `u280815660_school` schema.

Before running `./vendor/bin/phpunit` or `php spark test`, copy `env` to `.env.testing` (or `.env`) and set the matching environment variables:

```
database.tests.hostname = localhost
database.tests.database = your_test_database
database.tests.username = your_username
database.tests.password = your_password
database.tests.DBDriver = MySQLi
database.tests.DBPrefix =
```

That ensures the `CIUnitTestCase` base class can connect, run migrations, and tear down data between tests. Once configured, run the suite with `./vendor/bin/phpunit` or `php spark test --testsuite=App` to validate the API.
