I was curious to see if there was a workaround, for those who want to develope multisites on their dev installs but on different ports than :80:80 and :443:443, e.g. 8080:8080.
<?php
/**
* Test for multisite support on a different port than :80 and :443 (e.g. :8080)
*
* Here we assume that the 'siteurl' and 'home' options containscontain the :8080 port
*
* WARNING: Not suited for production sites!
*/
/**
* Get around the problem with wpmu_createblogwpmu_create_blog() where sanitize_user()
* strips out the semicolon (:) in the $domain string
* This means created sites with hostnames of
* e.g. example.tld8080 instead of example.tld:8080
*/
add_filter( 'sanitize_user', function( $username, $raw_username, $strict )
{
// Edit the port to your needs
$port = 8080;
if( false ! $strict // wpmu_create_blog uses strict mode
&& is_multisite() // multisite check
&& $port == strposparse_url( $raw_username, ':8080'PHP_URL_PORT ) // raw domain has port
&& false === strpos( $username, ':8080'' . $port ) // stripped domain is without correct port
)
$username = str_replace( '8080'$port, ':8080'' . $port, $username ); // replace e.g. example.tld8080 to example.tld:8080
return $username;
}, 1, 3 );
/**
* Temporarly change the port from(e.g. :8080 ) to :80 to get around
* the core restriction onin the network.php page.
*/
add_action( 'load-network.php', function()
{
add_filter( 'option_active_plugins', function( $value )
{
add_filter( 'option_siteurl', function( $value )
{
// Edit the port to your needs
$port = 8080;
// Network step 2
if( is_multisite() || network_domain_check() )
return $value;
// Network step 1
static $count = 0;
if( 0 === $count++ )
$value = str_replace( ':8080'' . $port, ':80', $value );
return $value;
} );
return $value;
} );
} );
