Usage

The following snippet shows you how to add a new PDF global option and correctly handle any errors:

    add_action( 'init', function() {
        if ( class_exists( 'GPDFAPI' ) ) {
            $option = GPDFAPI::add_plugin_option( 'prefix_option_name', 'My Value' );

            if( true === $option ) {
                // Option Successfully Added
            } elseif( is_wp_error( $option ) ) {
                // Option key already exists
            } else {
                // There was a problem updating the database with your new option
            }
        }
    } );
