CodeIgniter Simple and Secure Twig

This package provides simple Twig integration for CodeIgniter 4.x.

If you use CodeIgniter 3, check master branch. But Upgrading to CodeIgniter 4 is strongly recommended.

• PHP 7.4 or later
• CodeIgniter 4.2.11 or later
• Twig 3.4.3 or later

$ cd /path/to/codeigniter/
$ composer require kenjis/codeigniter-ss-twig

$this->twig = new \Kenjis\CI4Twig\Twig();

You can override the default configuration:

$config = [
    'paths' => ['/path/to/twig/templates', VIEWPATH],
    'cache' => '/path/to/twig/cache',
];
$this->twig = new \Kenjis\CI4Twig\Twig($config);

Render Twig template and output to browser:

$this->twig->display('welcome', $data);

The above code renders Views/welcome.twig.

Render Twig template:

$output = $this->twig->render('welcome', $data);

The above code renders Views/welcome.twig.

$this->twig->addGlobal('sitename', 'My Awesome Site');

$twig = $this->twig->getTwig();

• base_url()
• site_url()
• anchor()
• form_open()
• form_close()
• form_error()
• form_hidden()
• set_value()
• csrf_field()
• validation_list_errors()

Some helpers are added the functionality of auto-escaping for security.

Warning validation_list_errors() shows Validation Errors by Services::validation()->listErrors(), and if you use user input for Validation Error messages, attackers may do XSS. In such a case, validate user input and escape it by yourself.

You can add your functions and filters with configuration:

$config = [
    'functions'      => ['my_helper'],
    'functions_safe' => ['my_safe_helper'],
    'filters'        => ['my_filter'],
];
$this->twig = new \Kenjis\CI4Twig\Twig($config);

If your function explicitly outputs HTML code, you want the raw output to be printed. In such a case, use functions_safe, and you have to make sure the output of the function is XSS free.
