Multiple domains using one WP install (not wpmu)

  • The solution here wasn’t quite working for me, so I created the script below. Point all domains you want to the same wordpress directory and replace your wp-config with the following (make sure to edit the variables for each domain):

    <?php
/* Determining the domain  - DO NOT EDIT */

$host = $HTTP_HOST;
$parts = explode('.',$host);
if ($parts[3] = "") {
    $domain = $parts[0];
} else {

    $domain = $parts[1];
}
/* Domain - Edit below. Add more "cases" for each domain you want to have.
   Make sure each "case" has a "break; line at the end.                */

switch ($domain) {
  case "domain1":		// "domain" in "www.domain.com"
    $db = "database1";		// the database for this domain
    $user = "username1";	// the username for this database
    $password = "pass1";	// the password for this database
    $hostname = "localhost";	// 99% chance you won't need to change this value
    $table_prefix  = 'wp_';	// change for multiple installations in one database
    $wplang = '';		// change to localize wordpress (must have an MO file in wp-includes/languages)
    break;

  case "domain2":		// "domain" in "www.domain.com"
    $db = "database2";		// the database for this domain
    $user = "username2";	// the username for this database
    $password = "pass2";	// the password for this database
    $hostname = "localhost";	// 99% chance you won't need to change this value
    $table_prefix  = 'wp_';	// change for multiple installations in one database
    $wplang = '';		// change to localize wordpress (must have an MO file in wp-includes/languages)
    break;
}

/* That's all, stop editing! Happy multi-blogging. */

define('DB_NAME', $db);
define('DB_USER', $user);
define('DB_PASSWORD', $password);
define('DB_HOST', $hostname);

define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
define ('WPLANG', $wplang);

define('ABSPATH', dirname(__FILE__).'/');
require_once(ABSPATH.'wp-settings.php');

  • Hi,

    Great post! it works!

    i was just wondering if you have a solution for subdomains ex(1.domain.com & 2.domain.com)… it does not seems to work in subdomains.

    I’ve been reading for a week now and your solution above seems so much easier than everything else I’ve come across. One question though – when you say “Point all domains you want to the same wordpress directory” are you talking about redirecting or symbolic links – or does it not matter?

    Hey Cusnum,
    If you read this, can you respond to kathleane’s question, please.
    Fn STDestiny doesn’t seem to be reading this board anymore.
    I have been spending way too much time on this issue, and I have none, and some stupid little question is not answered.
    RDB

    The solution given by STDestiny is the simplest I have come across too. However, I host on IIS6 and the $HTTP_HOST was returning null and thus I got HTTP 500 error when I used the script as is.

    I had to change that line, just like the original solution you referred, to make the config work :

    $host = $_SERVER['HTTP_HOST'];

    Place the following in a test.php and call it using https://www.yourdomain.com/test.php to check which will work for you:

    <?php
    echo '<pre>';
    var_dump($HTTP_HOST);
    var_dump($_SERVER['HTTP_HOST']);
    echo '</pre>';
?>

    One improvement can be made to the SWITCH statement in this wp-config.php file – add a default value to handle any erroneous situation. Add the following after the last ‘break;’ statement and put before the closing curly brackets:

    default:		// default config if everything fails
    $db = "defaultdb";	// the database for this domain
    $user = "defaultuser";	// the username for this database
    $password = "defaultpw";// the password for this database
    $hostname = "localhost";	// 99% chance you won't need to change this value
    $table_prefix  = 'wp_';	// change for multiple installations in one database
    $wplang = '';		// change to localize wordpress (must have an MO file in wp-includes/languages)

    Good thinking…STDestiny!
