Parameters

$option

(string) (Required) Name of the option to add. Expected to not be SQL-escaped.

$value

(mixed) (Required) Option value, can be anything. Expected to not be SQL-escaped.

Return

(bool) True if the option was added, false otherwise.

More Information

This function essentially the same as add_option() but works network wide when using WP Multisite.

The only major difference is that on multisite site-wide options will not autoload and on a single site the option will autoload. Unlike when using add_option() on a single site, the feature cannot be overridden.
