Embedded Video


This is a first try at an action / plugin embedding a video.

For now, the action embeds youtube and vimeo videos as easy as: {{video url="http://www.youtube.com/watch?v=-dnL00TdmLY"}}

Other parameters other than url are type and id (replaces url) and width and height (defaults at 440 / 330).

Save the following file as video.php under plugins/actions folder:

<?php
/**
 * Display a video.
 *
 * @package     Actions
 * @version     $Id$
 * @license     http://www.gnu.org/copyleft/gpl.html GNU General Public License
 * @filesource
 *
 * @uses    Wakka::htmlspecialchars_ent()
 * @uses    Wakka::cleanUrl()
 *
 * @input   string  $url    optional: URL of video to be embedded (either this or both type and id must be set)
 * @input   string  $type   optional: type of video (youtube, vimeo)
 * @input   string  $id     optional: id of video resource
 * @input   int     $height optional: height of the video
 * @input   int     $width  optional: width of the video
 * @output  string  object element
