Multisite Blog Alias


Thanks for sharing! Works like a charm!


Just works!


This let me do exactly what I needed to do in the most ideal/streamlined/WordPress-integrated way I could imagine it being implemented (it can be so annoying when plugins create their own admin page layout, tables, tabs, styles, etc. when they could've/should've just used what WordPress offers for those as standard, like this plugin has done.) It's flexible depending on certain needs & even has WP-CLI commands without having feature creep of stuff that's unrelated to this plugin's core goal (also on GitHub and doesn't have any ads/promos/upgrades like other plugins.) Even the "Check Status" tool when viewing a site's domain alias(es) is capable (checks many different possible situations [great to see the whatsmydns.net mention for if/when a DNS change might be needed]) yet concise to then be addressed swiftly.



I simply network-enabled the plugin, edited the site details to add the Alias Domain(s), and it worked! This plugin really checked off every box to have this be a top-recommended plugin for this (now more people just need to find out about this & use it instead of hard-coding redirects/rewrites or using plugins that, simply put, aren't as nice as this one. Honestly, this seems like a go-to if/when a WordPress multi-site network has a site on it that wants to use "www." as the primary domain of the site while then not including "www." has WordPress wanting to show either the "register a site" or "you cannot register a site here" since it's considered as a different subdomain & therefore a different site (even though a site that doesn't want to use "www." still resolves properly when that is provided in the URL)... maybe WordPress core will make that no longer needing to be manually accommodated, but this is now my favored way to handle this (replacing rewrites/redirects [especially if/when on nginx or some other hosting setup that might be more restrictive where WordPress should probably just handle it.])



Even the "Donate to this plugin" link for this plugin's details on WP.org is currently going to UN Refugees instead of themselves. This plugin has really earned its praise.


Feature Complete yet Simple to Use (Great for WP Multi-Site Network "www.")

<p>With the Pronamic Domain Mapping plugin you can easily publish a page on the domain aliases or pointers of your hosting solution. This way you can easily publish landing pages on the extra domain names you own.</p>
<h4>WordPress Network</h4>
<p>If you work with an WordPress Network and want to enable domain pages you have<br />
to add the following line to your /wp-content/sunrise.php file.</p>
<pre><code>$file = WP_CONTENT_DIR . '/plugins/pronamic-domain-mapping/sunrise.php'; 

if ( is_readable( $file ) ) {
    include $file;
}
</code></pre>
