You are correct. No special changes to the WordPress files that I can remember. I only did two things other than making a custom WP theme:

1. My site’s home (which is CodeIgniter) uses the SimplePie library to grab my latest comments in the sidebar and my latest blog posts in the main content from their RSS feeds. The library page explains how to use SimplePie 1.0.1 with CI but I successfully used the latest version right now which is 1.2.
2. The sidebar on my blog’s home (which is WP) has a section called “Pages” which lists links to my CI pages. The top navigation on the other hand is using the WP plugin called Page Links To. I’m using version 2.3 but the latest is 2.4 at the moment. This enables you to make WP pages just link to a URL (which in my case is a CI page on my site). So, I made a WP page for each CI page I had in my navigation and linked it to their respective pages using the plugin. As a result, when I search for “about” in my blog section, I get a link to my About CI page and a blog post.

I hope I answered all of your questions. If you need anything else, please don’t hesitate. Thanks for finding my blog and for your comment.

Congrats on the launch of your blog.

I found your site while looking for solutions to integrating Codeigniter 1.7 and WordPress 3.0

I have a site that is built completely with Codeigniter. I want to integrate a WordPress blog and share WP and my custom Codeigniter functions seamlessly through the site.

Things like:
* Have access to ‘logged in’ user information from main site into the blog section
* WP post excerpts, titles, ect available in the main site
* Main site statistics (it is a NASCAR statistics site) available in the sidebar of the blog, etc.

I’m completely comfortable making my own custom theme to carry over the visual aspect from Codeigniter site to WordPress section. Just not sure about the stuff I mentioned above.

I guess I should just break down and try it, but I read so much about issues people have integrating the two. No ones previous posts seem to convince me of the success of doing the things I’ve outline.

I’d much rather enjoy the great benefits that WordPress offers over Expression Engine.

Bottom line. You are saying that you have done a full install of WP in a directory called ‘blog’. Meanwhile, the rest of your site is built using Codeigniter? No problems, no changes to the files?

But…I guess I am still looking for a solution to carrying over the functions between the two, right? You haven’t done that?
