35 * Plugin for OpenX Ad Server
37 * This plugin supports the OpenX ad server, http://www.openx.org/
39 * We support the 4 ad sizes for the Universal Ad Platform (UAP):
46 * They fit in different places on the default theme. Some themes
47 * might interact quite poorly with this plugin.
49 * To enable advertising, you will need an OpenX server. You'll need
50 * to set up a "zone" for your StatusNet site that identifies a
51 * kind of ad you want to place (of the above 4 sizes).
53 * Add the plugin to config.php like so:
55 * addPlugin('OpenX', array('adScript' => 'full path to script',
58 * Here, the 'adScript' parameter is the full path to the OpenX
59 * ad script, like 'http://example.com/www/delivery/ajs.php'. Note
60 * that we don't do any magic to swap between HTTP and HTTPS, so
61 * if you want HTTPS, say so.
63 * The 'rectangle' parameter is the zone ID for that ad space on
64 * your site. If you've configured another size, try 'mediumRectangle',
65 * 'leaderboard', or 'wideSkyscraper'.
67 * If for some reason your ad server is different from the default,
68 * use the 'adScript' parameter to set the full path to the ad script.
