  • mixed $newvalue: Option value. Expected to not be SQL-escaped.

Return values

returns:False if value was not updated and true if value was updated.

Defined filters

  • pre_update_option_$option
    apply_filters( 'pre_update_option_' . $option, $newvalue, $oldvalue )

Defined actions

  • update_option
    do_action( 'update_option', $option, $oldvalue, $_newvalue );
  • update_option_{$option}
    do_action( "update_option_{$option}", $oldvalue, $_newvalue );
  • updated_option
