MultiDomain

• Point multiple domains/sub-domains at a single WordPress installation and maintain link integrity (i.e. if you’re on http://foo.com, links will be http://foo.com/bar, and if you’re http://baz.com links will be http://baz.com/bar)
• Overwrite site title, description, or theme per domain
• Customize content per domain using the [MultiDomain_if] and [MultiDomain_else] shortcodes

If you need more customization between domains, WordPress MU is a better option.

Configuration Examples

Note that you usually won’t need to configure your primary domain — MultiDomain will automatically fall back to your WordPress defaults if not configuration is present for a domain.

Basic

In config.php:

<?php
  $domains = array(
    array(
      'domain' => 'myalternatedomain.com',
      'siteurl' => 'http://myalternatedomain.com',
      'home' => 'http://myalternatedomain.com'
    )
  );
?>

More Complex

In config.php:

<?php
  $domains = array(
    array(
      'domain' => 'example1.com',
      'siteurl' => 'http://example1.com',
      'home' => 'http://example1.com'
    ),
    array(
      'domain' => 'example2.com',
      'siteurl' => 'http://example2.com',
      'home' => 'http://example2.com',
      'blogname' => 'Example 2'
    ),
    array(
      'domain' => 'example3.com',
      'siteurl' => 'http://example3.com',
      'home' => 'http://example3.com',
      'template' => 'twentyten',
      'blogname' => 'I have a different name...',
      'blogdescription' => '..and description'
    )
  );
?><h3>Tag Usage</h3>

The provided short codes let you tailor your content per domain if needed. [MultiDomain_else] and [MultiDomain_default] are identical.

[MultiDomain_if domain="example1.com"]
  Content only people visiting on example1.com will see.
[/MultiDomain_if]

[MultiDomain_else]
  Content anyone visiting on any other domain will see.
[/MultiDomain_else]

Normal content everyone will see.
