Local Environment
Kalabox
If you are using Kalabox, you should have some basic conditionals that setup your settings.php to operate on Pantheon and your local Kalabox:
/**
* Terminatur
*
* These local settings were generated by terminatur.
* You may see them if you use Kalastack, Kalabox, Proviso or other local dev
* tools.
*
*/
if (isset($_SERVER['KALABOX']) && $_SERVER['KALABOX'] === 'on') {
// DB Array and some common conf.
$databases['default']['default'] = array(
'driver' => 'mysql',
'database' => 'mysite_kala',
'username' => 'root',
'password' => 'password',
'host' => 'localhost',
'port' => '3306',
'prefix' => '',
);
// Error reporting
error_reporting(-1); // Have PHP complain about absolutely everything.
$conf['error_level'] = 2; // Show all messages on your screen
ini_set('display_errors', TRUE); // These lines give you content on WSOD pages.
ini_set('display_startup_errors', TRUE);
// Set some common desirable local vars.
$conf['file_temporary_path'] = '/tmp';
$conf['file_public_path'] = 'sites/default/files';
$conf['file_private_path'] = 'sites/default/files/private';
$conf['reroute_email_enable'] = 1;
$conf['cache'] = 0;
$conf['css_gzip_compression'] = FALSE;
$conf['js_gzip_compression'] = FALSE;
$conf['preprocess_css'] = 0;
$conf['preprocess_js'] = 0;
$conf['site_name'] = 'mysite Local';
$conf['cron_last'] = '9999999999';
}
Non-Kalabox
If you aren't on Kalabox, you should setup something similar. Make sure you don't overwrite any of the existing Kalabox settings or Pantheon configuration:
if (isset($_SERVER['KALABOX']) && $_SERVER['KALABOX'] === 'on') {
// Kalabox stuff from above would be here.
} else {
// Your custom local environment db configuration and the sane defaults
// shown in the Kalabox config above should be here.
}
301 Redirect to Single Domain
On most sites that are going live, we'll want to make sure all requests are directed to a single domain for ideal SEO and user experience. We do this with a permanent 301 redirect.
In this example, we're making sure that the default Pantheon domain AND www.mysite.com are redirected to the non-www domain:
if (isset($_SERVER['PANTHEON_ENVIRONMENT'])) {
if($_SERVER['PANTHEON_ENVIRONMENT'] === 'live') {
// settings for launching Featured Events
if($_SERVER['HTTP_HOST'] == 'live-mysite.gotpantheon.com' || $_SERVER['HTTP_HOST'] == 'www.mysite.com'){
header('HTTP/1.0 301 Moved Permanently');
header('Location: http://mysite.com'. $_SERVER['REQUEST_URI']);
exit();
}
}
}
Partial Redirects going to legacy site with a new site (Kettering did this)
// REDIRECTS
if (isset($_SERVER['PANTHEON_ENVIRONMENT'])) {
// Easily Change status code and base url for testing here:
$host = 'my.kettering.edu';
$http_code = 'HTTP/1.0 303 See Other';
$redirect = FALSE;
// Add URLS to skip this AKA 1-1:
$skip = array(
'/admissions',
);
// Set this to a var so we don't mess with doing all this fun stuff below.
$uri = $_SERVER['REQUEST_URI'];
// Redirect to legacy site based on set patterns, etc.
if (!in_array($uri, $skip)) {
// Wildcard Redirects.
$wildcard = array(
'academics',

Full Settings.php Sample
Here is an example portion of a settings.php with environmental magic on Pantheon
There is an example 404 redirect config, and a redirect for a path part to a subdomain.
Also, a placeholder for 301 redirects.
note that there are 2 different ways to check the Pantheon environment, here – one for config, the other for web actions like redirects.
