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' => '',
  );
  // 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:

if (isset($_SERVER['PANTHEON_ENVIRONMENT'])) {
  /**
   * Redirect 404 config to the D6 site to hide D7 development
   * REMOVE ME ON LAUNCH
   */
  $conf['redrect_404_search'] = 'http://www.mysite.com/search/apachesolr_search';
  $conf['redirect_404_redirect'] = 'http://www.mysite.com';
  $conf['redirect_404_servers'] = 'http://www.mysite.com';

  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();
    }
  }
}

 

Full Settings.php Example

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.

(warning) note that there are 2 different ways to check the Pantheon environment, here – one for config, the other for web actions like redirects.

setttings.php
<?php
 
// all other defaults go here
 

/*
* settings for all environements

// Avoid Image resize threshold error
$conf['image_resize_filter_threshold'] = 1000;
