Getting Started with CodeIgniter 4 PreAlpha 1

One thing I forgot to mention in that post, but that is worth knowing is that the default environment is now "production" to save any accidents when pushing to a live site. To change the environment to development, the best thing is to edit the .htaccess file (if using Apache) that came with the download. Toward the top is a line like:

Code:

# SetEnv CI_ENV development

Uncomment that line and you're good to go.

How to do this in nginx?

Code:

fastcgi_param CI_ENV development;

Thank You

I've played with CI4 and I don't know where is the proper place to mention mistakes in the documentation and errors in CI itself. A few problems that I've found:

- The correct place of .env files is not the /application directory, but the root directory (where the composer.json lives).
- $_ENV global variable and getenv function works normally, but if I try to use them in the Database config I get the following error:
Fatal error: Constant expression contains invalid operations in /media/sf_code/ci4.dev/gitroot/ci4/application/Config/Database.php

I have used CI for quite some time and created all localhost files to be a mirror image of the onsite files. This was done by creating the following constant:

PHP Code:

defined('LOCALHOST') || define('LOCALHOST', 'localhost'===$_SERVER['SERVER_NAME']); 


Differences such as paths, adverts, display Analytics, etc could then be switched out locally using the following:

PHP Code:

if( ! LOCALHOST):
    require VIEWPATH .'incs/adverts-800x160.php';
    require VIEWPATH .'incs/analytics.php';
endif; 


I tried using this method with the CI4 installation and the class namespace created problems

I eventually managed to find a solution by using the following:
.htaccess

Code:

# Sets the environment that CodeIgniter
   SetEnv CI_ENVIRONMENT  development
   SetEnv LOCALHOST       true
   SetEnv CI_SYSDIR      /home/john/www/ci2/CodeIgniter4/system
   SetEnv CI_SERVER      thisisatesttoseeifitworks.ga/
   SetEnv CI_PUBDIR      public_html

index.php

PHP Code:

# SetVar Constants MUST BE SET IN .htaccess
  defined('LOCALHOST') || define('LOCALHOST', getenv('LOCALHOST') );
  defined('CI_SERVER') || define('CI_SERVER', getenv('CI_SERVER') );
  defined('CI_SYSDIR') || define('CI_SYSDIR', getenv('CI_SYSDIR') );
  defined('CI_PUBDIR') || define('CI_PUBDIR', getenv('CI_PUBDIR') ); 


These two files require modifing:
./Config/App.php

PHP Code:

    # public $systemDirectory = '../system';
    public $systemDirectory = CI_SYSDIR;     // '/home/john/www/ci2/CodeIgniter4/system';
    public $baseURL = 'https://' .CI_SERVER; // ''; 


./Config/Paths.php

PHP Code:

public $publicDirectory = CI_PUBDIR ;  // 'public'; // public'; 


Using this technique gives peace of mind knowing that any file modified locally will not create problems when uploaded.

I have just used the above method and the installation worked first time!

I was wondering if this could be applied to the current CI4 installation?
