is_site_meta_supported() WordPress Function
The is_site_meta_supported() function is used to check whether a given site supports meta data. This function is useful for plugin and theme developers who need to know whether a site has the ability to store and retrieve meta data.
is_site_meta_supported() #
Determines whether site meta is enabled.
Description
This function checks whether the ‘blogmeta’ database table exists. The result is saved as a setting for the main network, making it essentially a global setting. Subsequent requests will refer to this setting instead of running the query.
Return
(bool) True if site meta is supported, false otherwise.
