Any settings supported -by [slide] can be set into [presentation], which will apply that setting for the entire -presentation unless overridden by individual slides. - -- [presentation] only settings: - - duration: transition durations, default is one second. - - height: content height, default is 400px - - width: content width, default is 550px - - autoplay: delay between transitions in seconds, default 3s - when set the presentation will automatically transition between slides - as long as the presentation remains in focus - -- [slide] settings: - - transition: specifies where the next slide will be placed relative - to the last one before it. Supported values are "up", "down" - "left", "right", or "none". Default value is "down". - - - scale: scales the content relative to other slides, default value is one - - - rotate: rotates the content by the specified degrees, default is zero - - - fade: slides will fade in and out during transition. Values of "on" or - "true" will enable fading, while values of "no" or "false" will - disable it. Default value is "on" - - - bgcolor: specifies a background color for the slides. Any CSS valid value - is permitted. Default color is transparent. - - - bgimg: specifies an image url which will fill the background. Image is - set to fill the background 100% width and height - - - fadebullets: any html <li> tags will start out with an opacity of 0 and any - subsequent slide transitions will show the bullets one by one -*/ - -if ( ! class_exists( 'Presentations' ) ) : - class Presentations { - - private $presentation_settings; - private $presentation_initialized; - private $scripts_and_style_included; - - /** - * Constructor - */ - function __construct() { - $this->presentation_initialized = false; - $this->scripts_and_style_included = false; - - // Registers shortcodes - add_action( 'wp_head', array( &$this, 'add_scripts' ), 1 ); - - add_shortcode( 'presentation', array( &$this, 'presentation_shortcode' ) ); - add_shortcode( 'slide', array( &$this, 'slide_shortcode' ) ); - } - - function add_scripts() { - $this->scripts_and_style_included = false; - - if ( empty( $GLOBALS['posts'] ) || ! is_array( $GLOBALS['posts'] ) ) { - return; - } - - foreach ( $GLOBALS['posts'] as $p ) { - if ( has_shortcode( $p->post_content, 'presentation' ) ) { - $this->scripts_and_style_included = true; - break; - } - } - - if ( ! $this->scripts_and_style_included ) { - return; - } - - $plugin = plugin_dir_url( __FILE__ ); - // Add CSS - wp_enqueue_style( 'presentations', $plugin .
