Codeigniter how to properly use base_url?

Question

I am having a little trouble with base_url in codeigniter, let's say if I don't set my $config['base_url'] in the config/config.php file, calling base_url will produce [::1], this is not what I want, I want it to return localhost, so I set $config['base_url'] = 'localhost' , yup it return localhost/bla/bla

when accessed locally, HOWEVER if I access my project remotely from another computer, it DOES keep returning 'localhost' too while what I want is to return the base_url as in the ip address of the server (ie 192.168.1.8 etc).

I am very sure CI team has thought this through and has a special solution or parameter in the base_url however I wasn't able to find it or I am not searching enough. Anyway thanks in advance.

Answer 1

To use base_url(), you have to load the URL Helper first

$this->load->helper('url');

Or you can autoload it by changing application/config/autoload.php

Or just use

 $this->config->base_url();

Same applies to site_url().

and use like this

<link rel="stylesheet" href="<?php echo base_url(); ?>css/default.css" type="text/css" />

you can follow this url

Answer 2

您可以使用主机动态分配base_url

$config['base_url'] = 'http://'.$_SERVER['HTTP_HOST'].'/';
