Filters the value of all existing options before it is retrieved.

Returning a truthy value from the filter will effectively short-circuit retrieval and return the passed value instead.

$pre_option mixed

The value to return instead of the option value. This differs from $default, which is used as the fallback value in the event the option doesn't exist elsewhere in get_option() .
Default false (to skip past the short-circuit).

$option string

Name of the option.

$default mixed

The fallback value to return if the option does not exist.
Default false.
