WordPress.org

EMC2 Popup Disclaimer uses Fancybox (http://fancybox.net) to display the popup, and jQuery-cookie (https://github.com/carhartl/jquery-cookie) to detect user session. Creates a cookie named "emc2pdc" that can be viewed with regular developer tools.

Easy to use! By default the script is added to the wp_footer action and will work quietly. You can also force the display on pages via shortcode or function call:
Shortcode: [emc2pdc id="42"]
-or-
Function: <?php emc2pdc_force( $atts=array(), $force=NULL, $id=NULL ); ?>

To Do list:

• Add No-JS fallback support
• Create a selection of button themes
• Add support for different lightbox types
• Improve handling, add PHP cookie support

Known bugs:

• Recursive post shortcode call results in chaos
