pre_option_(option) filter-hook . WP 1.5.0

Filters the value of an existing option before it is retrieved.

The dynamic portion of the hook name, $option, refers to the option name.

Passing a truthy value to the filter will short-circuit retrieving the option value, returning the passed value instead.

Usage

add_filter( 'pre_option_(option)', 'filter_function_name_8734', 10, 3 );
function filter_function_name_8734( $pre_option, $option, $default ){
	// filter...

	return $pre_option;
}
$pre_option(true/false/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)
Option name.
$default(mixed)
The fallback value to return if the option does not exist.
Default: false

Changelog
