The following tutorial will display your latest WordPress posts in a news ticker format. The code is basically the same as my popular post Display Your Latest Posts on a Static Page except that the output is in an unordered list for the jQuery news ticker to work. This tutorial is meant for non WordPress websites to access their WordPress powered blog. To add a news ticker to your WordPress powered blog to display your latest posts try this tutorial. To add a news ticker to your WordPress blog with external RSS feeds try this tutorial.
Primarily the focus of this tutorial is to display your cached tweets using PHP and OAuth on your WordPress website. We will be accessing the secure Twitter 1.1 API with PHP by parsing and caching the JSON file using the WordPress API. It may seem a lot of code just to display your latest tweets on your website but the benefits are that you can style it to the taste of your theme with a little CSS and caching the JSON file will not add extra load on the Twitter API.
New Update. I have packaged all of the features and more into a WP plugin. Please remember to remove any of the code used from this post before installing the plugin. Check out WOW-Twitter.
As you may, or may not know, Twitter are going to depreciate version 1 of their API next March. What does this mean to you? If you currently parse the Json file to display your tweets you will no longer be able to have access unless you use the authentication features. Why authentication? Various reasons I assume to limit users from making unnecessary calls to the API, Security reasons. How do I go about it? Well now you will have to create a Twitter App then use a form of authentication to make the API call.
