pre_option
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.
Usage
add_filter( 'pre_option', 'wp_kama_pre_option_filter', 10, 3 ); /** * Function for `pre_option` filter-hook. * * @param mixed $pre_option The value to return instead of the option value. This differs from `$default_value`, which is used as the fallback value in the event the option doesn't exist elsewhere in get_option(). * @param string $option Name of the option. * @param mixed $default_value The fallback value to return if the option does not exist. * * @return mixed */ function wp_kama_pre_option_filter( $pre_option, $option, $default_value ){ // filter... return $pre_option; }
- $pre_option(mixed)
- The value to return instead of the option value. This differs from $default_value, 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_value(mixed)
- The fallback value to return if the option does not exist.
Default: false
