Achieve access to any domain name

Note: Add the following code to the wp-config.php file to ensure that all bound and resolved domain names can access the blog normally without being connected to other domain names.

define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST']); define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST']);

or

$home = 'http://'.$_SERVER['HTTP_HOST']; $siteurl = 'http://'.$_SERVER['HTTP_HOST']; define('WP_HOME', $home); define('WP_SITEURL', $siteurl);

PHP $_SERVER['HTTP_HOST']  Used to obtain the source domain name. In this way, WP_HOME and WP_SITEURL Variable assignment to implement WordPress multi-domain binding.

Implement https access to any domain name

define('WP_SITEURL', 'https://' . $_SERVER['HTTP_HOST']); define('WP_HOME', 'https://' . $_SERVER['HTTP_HOST']);

or

$home = 'https://'.$_SERVER['HTTP_HOST']; $siteurl = 'https://'.$_SERVER['HTTP_HOST']; define('WP_HOME', $home); define('WP_SITEURL', $siteurl);

How to restrict specific domains from accessing WordPress websites? Restrict access to specific domains

You can also specify that only certain domain names can be accessed. $domain = array("www.a.com", "www.b.com", "www.c.com"); Change the domain name in the brackets to the domain name you want to bind. This way, you can set the domain names you added to be accessible normally, while other domain names that have not been added cannot be accessed.

Set the website domain name to the currently visited domain name, that is, cancel the domain name binding. If you do not need any domain name to be accessible

$domain = array("www.a.com", "www.b.com", "www.c.com"); if(in_array($_SERVER['HTTP_HOST'], $domain)){ define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST']); define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST']); }

Just put the specified domain name in the $domain array.

How to modify the static resource address to accommodate multiple bound domain names?

Your website can already achieve multi-domain access, but there is still a problem, that is, static resources. When the pictures uploaded to WordPress are inserted into the article, the address is fixed. After changing the domain name, the domain name of the picture will not be changed, so you also need to modify the static file address. Use the following code to solve it:

define( 'WP_CONTENT_URL', '//' . $_SERVER['HTTP_HOST'] . '/wp-content');

Add this code below the above code. OK, now your website has perfectly broken through the restriction of domain name binding.
