Requirements

• PHP 7.3.0 or later

• Composer

• php-gd

• php-mbstring

• php-xml

• php-imagick
  The method to extract the first frame from a GIF (extractFirstFrameOfGif) in the \X\Util\ImageHelper class requires ImageMagick.
  To use this method, install ImageMagick and php-imagick.

  • For Amazon LInux 2 OS:

    sudo yum -y install ImageMagick php-imagick

  • For Amazon LInux 2023 OS:
    1. Install ImageMagic and PECL.

       sudo dnf -y install ImageMagick ImageMagick-devel php-pear.noarch

    2. Install imagick with PECL.

       sudo pecl install imagick

    3. Add imagick.so link in /etc/php.ini.

       extension=imagick.so

    4. Restart php-fpm and nginx.

       sudo systemctl restart nginx
       sudo systemctl restart php-fpm

Getting Started

1. Create project.

   composer create-project takuya-motoshima/codeigniter-extension myapp

2. Grant write permission to logs, cache, session to WEB server.

   sudo chmod -R 755 public/upload application/{logs,cache,session}
   sudo chown -R nginx:nginx public/upload application/{logs,cache,session}

3. Set up a web server (nginx).
   If you are using Nginx, copy nginx.sample.conf to /etc/nginx/conf.d/sample.conf.
   Restart Nginx.

   sudo systemctl restart nginx

4. Build a DB for init.sql (MySQL or MariaDB).
5. The skeleton uses webpack for front module bundling.
   The front module is located in ./client.
   How to build the front module:

   cd client
   npm run build

6. Open http://{public IP of the server}:3000/ in a browser and the following screen will appear.
   NOTE: You can log in with the username robin@example.com and password password.

   

   

   

Usage

See https://codeigniter.com/userguide3/ for basic usage.

• About config (application/config/config.php).

  Name	Before	After
  base_url		if (!empty($_SERVER['HTTP_HOST'])) $config['base_url'] = '//' . $_SERVER['HTTP_HOST'] . str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
  enable_hooks	FALSE	TRUE
  permitted_uri_chars	a-z 0-9~%.:_\-	a-z 0-9~%.:_\-,
  sess_save_path	NULL	APPPATH . 'session';
  cookie_httponly	FALSE	TRUE
  composer_autoload	FALSE	realpath(APPPATH . '../vendor/autoload.php');
  index_page	index.php

• Control of accessible URLs.

  1. Define a controller to be executed when the root URL is accessed.
     In the example below, the login page is set to open when the root URL is accessed.

     application/config/routes.php:

     $route['default_controller'] = 'users/login';

  2. Define login session name.
     application/config/constants.php:

     const SESSION_NAME = 'session';

  3. Create control over which URLs can be accessed depending on the user's login status.
     At the same time, add env loading and error handling in pre_system.

     application/config/hooks.php:

     use \X\Annotation\AnnotationReader;
     use \X\Util\Logger;
     
     $hook['post_controller_constructor'] = function() {
       if (is_cli())
         return;
       $CI =& get_instance();
       $meta = AnnotationReader::getAccessibility($CI->router->class, $CI->router->method);
       $loggedin = !empty($_SESSION[SESSION_NAME]);
       $current = lcfirst($CI->router->directory ?? '') . lcfirst($CI->router->class) . '/' . $CI->router->method;
       $default = '/users/index';
       $allowRoles = !empty($meta->allow_role) ? array_map('trim', explode(',', $meta->allow_role)) : null;
       if (!$meta->allow_http)
         throw new \RuntimeException('HTTP access is not allowed');
       else if ($loggedin && !$meta->allow_login)
         redirect($default);
       else if (!$loggedin && !$meta->allow_logoff)
         redirect('/users/login');
       else if ($loggedin && !empty($allowRoles)) {
         $role = $_SESSION[SESSION_NAME]['role'] ?? '';
         if (!in_array($role, $allowRoles) && $default !== $current)
           redirect($default);
       }
     };
     
     $hook['pre_system'] = function () {
       $dotenv = Dotenv\Dotenv::createImmutable(ENV_DIR);
       $dotenv->load();
       set_exception_handler(function ($e) {
         Logger::error($e);
         show_error($e->getMessage(), 500);
       });
     };

  4. After this, you will need to create controllers, models, and views, see the demo for details.

• About Twig Template Engine.
  This extension package uses the Twig template.
  See here for how to use Twig.

  In addition, the session of the logged-in user is automatically set in the template variable.
  This is useful, for example, when displaying the login username on the screen.

  PHP:

  $_SESSION['user'] = ['name' => 'John Smith'];

  HTML:

  {% if session.user is not empty %}
    Hello {{session.user.name}}!
  {% endif %}
    Who is it?
  {% else %}

Testing

The unit test consists of the following files.

• tests/*.php: Test Case.
• phpunit.xml: Test setting fill.
• phpunit-printer.yml: Test result output format.

composer test
