Exponent CMS Blog

I have been working this week on updating some of my Exponent sites to take advantage of the mobile theming feature now available in Exponent 2. In a nutshell, the feature allows you to define a separate index.php file that will be viewed by clients using mobile browsers. You can also use specific CSS code to adjust the appearance of your page to better suit the browsing of small screen mobile devices.

When Exponent v2.0.2 was released at the end of October 2011 it incorporated a fairly major change under the hood that could 'break' some custom themes or mods.  The template engine (what is used to display everything) was upgraded from Smarty v2.5.x to v3.1.x.  This was a major upgrade, but the syntax basically remained the same...the issue is that 'bad' template code which worked under previous versions will likely break with this version.  However, Smarty v3 adds many enhancements including the ability to use inline computations/math.  Details on how to identify problems and fixes is at the end of this post.

YUI 3.2 and earlier had no browser based detection loading, and worked well with YUI PHP Loader, allowing for Exponent to load YUI dependencies on the server side. Since the introduction of YUI 3.3.0, which loads (and skips loading) JavaScript based on your browser, it's now only YUI 2.x that can take advantage of server-side dependency calculation and loading, since PHP has no sure-fire way to detect the user's browser. The result: Exponent YUI 2 loading up on the server, and YUI 3 loading via YUI3's built-in Loader.

Here are some basics of using git and github to initially get or update the code to your site.  I've found this is an easy way to initial install, and the perform updates on my web sites.  There is a little bit of overhead (~105 MBytes), however the reduction in effort is worth it in most cases.

As a general rule of thumb, any images that will be placed into text modules should be resized using an external image editing program such as Microsoft Picture Manager or Picasa before it is uploaded to the Exponent CMS File Manager.

To insert an image from the Exponent CMS File Manager into a Text module, you must first click the edit icon on the text module to begin editing the module.

Exponent CMS offers a robust permissions system giving Site Administrators the power to easily grant Viewing and Editing rights on a granular level. It is very easy to create these Password Protected pages using any combination of usernames, passwords, and group rights.

The first in our series of my How To tutorials for Site Administrators starts with the process of how to upload files to the file manager on an Exponent CMS website.
