Domain Theme allows you to specify more then one domain name with your WordPress installation and optionally associate a specific theme for each domain. This enables you to present your site under multiple domain names. (i.e. www.mypersonalblog.com and www.myprofessionalblog.com). A specific theme template can be assigned to a specific domain. For instance, you can use this plugin for a personal blog that has a casual theme under one domain and and present the same data under a corporate theme that omits select categories (i.e. family photos, etc.). You will need to modify your DNS settings to point your domain name(s) to the same server to make this happen.
Known Issues:
<ul>
<li>
Upgrade users from WordPress 2.6 to WordPress 2.6.1 who used version 1.2 may have incompatible domain data. Please delete and recreate your domain list.
</li>
<li>
All-In-One SEO users should delete their “Home title” setting otherwise it will overwrite the blog title settings in Domain Theme.
</li>
<li>
Please note that accessing wp-admin pages from any other domain name then your primary domain specified in ‘General Settings’ will cause the administration panel to report the ‘themed’ settings. Just remember to access your ‘General Settings’, ‘Presentation’, and ‘Domain Theme’ admin pages under your primary domain name if you want to make such changes.
</li>
<li>
Users before version 2.5 will have a minor UI issue on the Domain Theme control panel’s ‘delete all’ checkbox column. It will not check off all listed items.
</li>
<li>
The first item in the Domain Theme list cannot be deleted as it is the settings you have for your primary domain taken from the ‘General Settings’ and ‘Presentation-Theme’ page. Clicking it to edit will simply transfer you to the ‘General Settings’ page. This is on purpose.
</li>
<li>
Some users may have issues with their server variables SERVER_NAME versus HTTP_HOST. Simply uncomment the first line of code in the plugin if your additional domain names do not appear to work. See the comment on the first line of code.
</li>
</ul>

Domain Theme

Domain Theme allows you to specify more then one domain name with your WordPress installation and assign individual themes to each one.

WP Hydra has a quite straightforward purpose. Say you have a WordPress site, hosted on example.com. You’ve also purchased example.net and example.org, and you want them to also use the same website (the same installation), but to persist with that particular domain to have a consistent user experience. In other terms, you want your WordPress installation to be resolved and browsed at multiple domains. WP Hydra can help you with this.
Pointing multiple URLs to the same website is a good way to direct traffic to your site from several different domain names. You can accomplish this in two ways: either redirect one of the URLs to your primary domain, or park the domains, which point these domains towards your primary domain.
A redirect occurs when typing a web address in the address bar sends a visitor to another website (or URL), different from the one typed in. If this is your preferred case, then WP Hydra will not be of any need to you.
Parking a domain does the same thing as a redirect, except that the website name shown on the address bar does not change. You can park several domains to the same page. They have to be registered with a valid domain registrar before you can park them. Also, you’ll need to make sure the nameservers are the same as your primary domain (the domain that you are pointing towards).
Once your multiple domains point to the same website, you have to activate the plugin. No additional configuration or setup is required. This will make sure that the css, js, images and links that are leading to the original domain are now leading to the domain that you’re currently viewing. This will assure that the users remain on the site that they’ve originally visited, providing consistent experience.
<h3>Configuration</h3>
You only need to make sure that your multiple domains point to the same hosting, and to the same physical location on your hosting account.
Once this is done, simply install and activate the plugin – no additional configuration is needed.
<h3>Further customization – filters</h3>
If you have some custom content and you want the URLs within it to support multiple domains, you can use the <code>wp_hydra_content</code> filter, like this:
<pre><code>// we assume that you have some content in $content
$content = apply_filters( 'wp_hydra_content', $content );
</code></pre>
If you have some custom URLs somewhere and you want them multiple domains, you can use the <code>wp_hydra_domain</code> filter, like this:
<pre><code>// we assume that you have some content in $content
$url = apply_filters('wp_hydra_domain', $url);
</code></pre>
<h3>Further customization for developers</h3>
Since the <code>$wp_hydra</code> object is global, you can easily unhook any of the default functionality by simply calling <code>remove_action()</code> or <code>remove_filter</code> on it. The following example will remove the WP Hydra behavior of the content, but only for <code>the_content()</code> calls on the archive page:
<pre><code>add_action( 'wp_loaded', 'some_example_here' );
function some_example_here() {
 global $wp_hydra;
 if( is_archive() ) {
 remove_filter( 'the_content', array( $wp_hydra, 'setup_content' ) );
 }
}
</code></pre>

I had some AJAX issues with WPML and it's sub-domain setup. Thanks to this little gem, everything is working flawlessly (goodbye htaccess lines)!
I simply installed the plugin and the issues disappeared.
Great work!



A real time saver!

I needed a way to make a website accessible from two different domains.

After installing the plugin, everything worked out of the box.

Great work, thanks :)

Works as advertised

Allows one WordPress installation to be resolved and browsed at multiple domains.
