Base_url as a default value in a custom Config file

PHP Code:

namespace App\Config;

use CodeIgniter\Config\BaseConfig;

class MyConfig extends BaseConfig
{
    public $myTargetLink  = base_url() . '/path/to/link';

} 


Hello.

I am wondering how I can access the base_url in a Config file.

Doing this give me an error "Constant expression contains invalid operations"

Is getting the base_url() possible as a default value in a Config file?

Thanks for your time.

I don't know why you have this error. A workaround would be to define your config like this:

PHP Code:

class MyConfig extends BaseConfig
{
    public $myTargetLink = '/path/to/link';
} 


Then when you need it use base_url() like this:

PHP Code:

$myConfig = config('MyConfig');
echo base_url($myConfig->myTargetLink);

You can't use dynamic value like `base_url()` in defining properties.

PHP Code:

class MyConfig extends BaseConfig
{
    public $myTargetLink;

    public function __construct()
    {
        parent::__construct();

        $this->myTargetLink = base_url() . '/path/to/link';
    }

}

@sevmusic,

Perhaps consider defining the CONST in index.php and it will be available throughout the application:

file:  /index.php

PHP Code:

# DYNAMIC PATH ===================================================
  # dynamic BaseUrl - https://forum.codeigniter.com/thread-74649.html  
  if( TRUE || DEFINED('AUTOMATIC_URL_DETECTION') ) :
    $url = (isset($_SERVER['HTTPS']) && !empty($_SERVER['HTTPS']) 
        && 
        ('on' == $_SERVER['HTTPS']) 
        ? "https://" 
        : "http://") .$_SERVER['HTTP_HOST']
        ;
    $url .= str_replace
    (
      basename($_SERVER['SCRIPT_NAME']), 
      '', 
      $_SERVER['SCRIPT_NAME']
    );
  endif;  
  defined('BASE_URL') ?: define('BASE_URL', $url); # app/Paths.php, etc
# DYNAMIC PATH =================================================== 


[
file: app/Config/App.php

PHP Code:

  public $baseURL = BASE_URL; // http://localhost:8080/'; 


Good suggestions here! I will also add the Registrars are a great way to add dynamic content to Config files.
