actually the ternary operator x ? y : z; is faster than an if statement

so use this and it is even faster

$config['base_url'] = ($_SERVER['HTTP']=='localhost') ? 
  'http://localhost/path/to/local/folder/' : // local base url
  'http://www.server.tld/path/to/online/folder/'; // live base url

maybe not quite as readable however although the commenting helps

Guys, this Automatic config[base_url] solution is actually useful in letting you use multiple domains or addresses for the same website, not just 2 or 3.

@paulopmx: I’m aware of that, but setting up a new website starts with setting the configs anyway so I don’t really care about multiple domains. What I do care about is the problem mentioned in the opening post, which is setting up a site, making a slight config mod and uploading a config file that will not work on that server.

@tonanbarbarian: Nice, although I only compared mine to statements with multiple operators in it.

Please excuse my ignorance, how do you set certain pages to be HTTP while other pages are HTTPS? (for instance, a home page vs vs a enter billing info page)

First, be sure all links to secure pages are https. Second, in secure pages verify that the protocol is https. If not, then redirect using https.

It’s helpful to extend a common parent controller for all secure controllers. Then do the protocol check from the constructor of the secure parent controller.

Well depending on the server you would install a SSL certificate for the site - thus when https is used for the domain it knows where to pull the files from. What I’ve done is checks on certain pages so that if the user goes to the page and it’s not https that it will redirect them to the https connection.

Rick beat me to the answer - I guess I need to work on my typing speed.

awesome, thanks for the tip.

can this test just be

if(!$_SERVER['HTTPS']) {
//redirect to HTTPS
}

?

I’m not sure if that’s all encompassing or not (in other words, if that’s a good enough test for your suggestion above).
This is a “redundant” test as all links will be pointing to an HTTPS location, but have to make sure since people can type link locations manually.

What I wrote above is what I did, but CI’s redirect function is only relative, so I had to use good old fashioned “header(‘location: mypate.com’);”

Sorry, But can someone help me to understand following code. I am not sure why we need to check $_SERVER[‘HTTPS’] == “on”?

(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on")

Quoting php.net:

Set to a non-empty value if the script was queried through the HTTPS protocol. Note that when using ISAPI with IIS, the value will be off if the request was not made through the HTTPS protocol.

So, adding the localhost condition turns into something like:

$proto = "http" .
    ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "s" : "") . "://";
$server = isset($_SERVER['HTTP_HOST']) ?
    $_SERVER['HTTP_HOST'] : $_SERVER['SERVER_NAME'];
$server .= '/'; // Added since the trailing slash was not present in the above code

// Add the current subdirectory on a local server
    if (strstr($server, 'localhost'))
        $server .= 'bh/';

Test in a subdirectory on dev, upload to production on any domain.

Not sure there would be a way to automatically detect a subdirectory when also eliminating the index.php?  And in theory you could setup a nice dev environment with .testdomain.com…

What if user use .htaccess to remove ‘index.php’ from url??

index.php is not a part of the base_url setting that is the index_page setting so if you add index.php to the base_url you are going to have trouble with certain methods and functions.
