User Authentication with Codeigniter 1.7 using Twitter oAuth

by Adam Griffiths | May 2010 | Open Source PHP Web Development

User authentication is an important part of many applications. Let's look at how we would utilize third-party authentication methods. oAuth is an open protocol for secure user authentication across APIs. It allows users to gain limited access to websites by using their Twitter credentials. It's a very sound method of user authentication, and doesn't take too much work to get going. Twitter oAuth is used by hundreds of third-party Twitter clients and mashups—just to give you an idea of how useful it can be.

In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, we will:

  • Learn how Twitter oAuth works
  • Create a library for authentication
  • Utilize the library in order to create an application to demonstrate how it works

User Authentication with Codeigniter 1.7 using Facebook Connect

by Adam Griffiths | May 2010 | Open Source PHP Web Development

In a previous article we covered User Authentication with Codeigniter 1.7 using Twitter oAuth. In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, we will continue our discussion on how we can utilize third-party authentication methods by using Facebook Connect.

Facebook Connect is just like Twitter oAuth, but for Facebook accounts. It doesn't use the oAuth protocol, so its workings might seem slightly different to developers. To users, however, the difference is marginal. Just like in Twitter oAuth, users do not need to enter any of their account credentials on your website or application—it is all handled by Facebook.

Setting up a Complete Django E-commerce store in 30 minutes

by Jesse Legg | May 2010 | e-Commerce Open Source

In order to demonstrate Django's rapid development potential, we will begin by constructing a simple, but fully-featured, e-commerce store. The goal is to be up and running with a product catalog and products for sale, including a simple payment processing interface, in about half-an-hour. If this seems ambitious, remember that Django offers a lot of built-in shortcuts for the most common web-related development tasks. We will be taking full advantage of these and there will be side discussions of their general use.

In addition to building our starter storefront, this article aims to demonstrate some other Django tools and techniques. In this article by Jesse Legg, author of Django 1.2 e-commerce, we will:

  • Create our Django Product model to take advantage of the automatic admin tool
  • Build a flexible but easy to use categorization system, to better organize our catalog of products
  • Utilize Django's generic view framework to expose a quick set of views on our catalog data
  • Finally, create a simple template for selling products through the Google Checkout API
