CLS_DesignSwitcher

Uses a cookie to allow users to switch back and forth between the desktop and mobile themes as set using the native design exceptions under System -> Configuration -> Design.

How to Use

To use this module, first install it, then add links into the footer of your mobile and desktop themes:

Mobile Theme

Add this line of code to the footer of your mobile theme:

<a href="<?php echo Mage::helper('cls_designswitcher')->getMobileToDesktopUrl() ?>">View Full Site</a>

The controller for the designswitcher/switch/desktop route will place a USE_FULL_SITE cookie to indicate the design exception should be ignored. There is also a route to revert to the mobile theme (getDesktopToMobileUrl), although at this time it will not allow users of a desktop browser to view the mobile theme by clicking the link.

Desktop Theme

You will only want the "View Mobile Site" link to show if a user is viewing the desktop theme after having clicked on the "View Full Site" link from a mobile device. Because the link will need to be conditionally visible, you will need to include this block in your desktop theme's custom layout file (eg, local.xml):

<reference name="footer">
    <block type="cls_designswitcher/link" template="cls/designswitcher/link.phtml" name="designswitcher.link"/>
</reference>

The block is designed to work with Magento EE's Full Page Cache.

Installation

Copy module files into Magento root either manually or by using modman
Open app/etc/enterprise.xml and change global/cache/request_processor to CLS_DesignSwitcher_Model_Pagecache_Processor

Note: This is an important step. If missed the full page cache will not load the correct page when the cookie is set or vice-versa. There is unfortunately no other way to override the EE request processor on FPC hits.

Compatibility

This was built and tested on EE 1.13.0.2 and then slightly modified before being published here after light testing. So it should work as described, but in case you find a bug, feel free to send a pull request.
