Using WordPress ‘ms_site_check()’ PHP function

The ms_site_check() WordPress PHP function checks the status of the current blog.

Usage

ms_site_check();

See WordPress Developer Resources: ms_site_check()
This function was introduced in WordPress version 3.0.0.

The following code snippet checks the blog status and exits if it fails the check.

// Check the blog status
ms_site_check();

If the blog is deleted, you can create a custom blog-deleted.php file in the wp-content folder with a custom message.

// In your wp-content/blog-deleted.php file
echo "This blog has been deleted. Please contact the administrator for more information.";
exit;

If the blog is inactive, you can create a custom blog-inactive.php file in the wp-content folder with a custom message.

// In your wp-content/blog-inactive.php file
echo "This blog is currently inactive. Please check back later.";
exit;

If the blog is spammed or archived, you can create a custom blog-suspended.php file in the wp-content folder with a custom message.

// In your wp-content/blog-suspended.php file
echo "This blog has been suspended. Please contact the administrator for more information.";
exit;

You can combine ms_site_check() with other functions to perform additional actions if the blog passes the check.

// Check the blog status
ms_site_check();

// Additional actions if the blog passes the check
echo "The blog passed the check!";
