WP E-Commerce Multilanguage

Out-of-the-box, the default language for the WP E-Commerce plugin is English. As of this writing, the plugin lacks a convenient way for the customer to switch between languages, though hopefully, this is an upcoming feature. However, you may choose an alternate language for display on your store. There are currently nineteen language files available, and whichever one you select will be the one displayed on all of your stored pages. As there is currently no easy way for customers to switch between languages, choose whichever language your customers will expect.

WPML are working on a plugin that integrates with WP E-Commerce and thus gives it multilanguage facilities. You can read more about it here.

Including an Edit link on the WordPress front end

As you have probably seen, many themes have an Edit link visible on posts or pages when viewing them on the front end, provided you are logged in to the site with editing rights. When designing your own theme it is probably a good idea to implement this feature, especially for sites which will have alot of content. The simple reason is that it is much easier to find a page from the front end than from the back end, thus you will make life easier for the site administrators.

Use WordPress functions outside of WordPress

Just add the following piece of code in your file to have access to WordPress functions:

require($_SERVER['DOCUMENT_ROOT'].'/blog/wp-blog-header.php');

WordPress Custom Media Tabs

Plugins to Add Multiple Columns on your WordPress Page

Set from within the Page/Post itself using shortcodes (My favourite)

[column width="47%" padding="6%"] Column 1 content goes here. [/column]
[column width="47%" padding="0"] Column 2 content goes here. [/column]

Set from the template file
