重载CodeIgniter的base_url

Question

I have 54 sites that have different URLS but use the exact same codeigniter system AND application folders (before you think I spam for a living, the reality is that we own/manage 54 properties that use the same website 'template' and differentiate content for each via the database and/or separate asset folders in the vhosts/httpdocs folders.)

I placed the system and application folders for CI_2.0.3 in the vhosts directory above the httpdocs folder for each domain and can hit it successfully from two test sites with each showing the CI Welcome screen.

However, I am concerned about the base URL. If one is www.campuslodge.com and another is campuscreek.com, how do I handle that in a single config/config.php file? I can pass the property number to the application via the index.php file that exists in each of the 54 domain httpdocs folders, so can I also declare a global there for base_url and leave the one in config/config.php blank??? Or should I do something else???

Bottom line is that I need 54 unique domains to point to a single CI installation of both system and application so that I can make global changes once rather than 54 times.

Answer 1

you answered your question. Define a constant in each index.php, say:

define('_MY_BASE_URL', 'http://yourdoamin.com');

and in the config.php do:

$config['base_url'] = _MY_BASE_URL;
