Asset handling in CodeIgniter with the BASE tag

[eluser]Phil Sturgeon[/eluser]
I just posted an article on something I thought up a few days back: Asset handling in CodeIgniter with the BASE tag. I haven't seen this suggestion posted around the forums before so thought it might be worth mentioning.

It's been mentioned a few times in this forum, but more people should be aware of <base> tag. When combined with automatic base_url (below) detection, you can copy website from http://127.0.0.1/dev/project to http://www.project.com without any modification to configuration files or templates.

Code:

$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);

Who when and where? I'll kill em. I'll kill em with a pointy shoe.

As for automatic base_url, that is the way I normally handle things but I take it one step further.

config/constants.php

Code:

/*
|--------------------------------------------------------------------------
| Docment root folders
|--------------------------------------------------------------------------
|
| These constants use existing location information to work out web root, etc.
|
*/

// Base URL (keeps this crazy sh*t out of the config.php
if(isset($_SERVER['HTTP_HOST']))
{
    $base_url = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on' ? 'https' : 'http';
    $base_url .= '://'. $_SERVER['HTTP_HOST'];
    $base_url .= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
    
    // Base URI (It's different to base URL)
    $base_uri = parse_url($base_url, PHP_URL_PATH);
    if(substr($base_uri, 0, 1) != '/') $base_uri = '/'.$base_uri;
    if(substr($base_uri, -1, 1) != '/') $base_uri .= '/';
}

else
{
    $base_url = 'http://localhost/';
    $base_uri = '/';
}

// Define these values to be used later on
define('BASE_URL', $base_url);
define('BASE_URI', $base_uri);
define('APPPATH_URI', BASE_URI.APPPATH);

// We dont need these variables any more
unset($base_uri, $base_url);

That way I can use these handy constants throughout the entire application.

I mentioned it just the other day lol. Too far away to throw a pointy shoe at.

Just spotted that after looking over that post again. Both me and the author of the thread missed it. Nevermind, at least this explains why what and how.

Great stuff, thanks!

As a spot of extra fun, I use:

Code:

if (strstr($_SERVER['HTTP_HOST'], 'localhost'))
{
    $GLOBALS['live'] = false;

}
else
{
    $GLOBALS['live'] = true;

}

A simple hack to set a variable that I use in my database, and possibly other places, to do things only if they are on my computer and not the live server.

Have you conidered using constants for this?
