XF 1.5 How to integrate XF in your current Codeigniter website


New member
I have a website in Codeigniter v3.0.0 and I want to integrate XF v1.5 in my CodeIgniter website.
Things I want to do are

1. I want to use a single login and signup page for both my website and XF.
2. I want to use custom header and footer on XF pages. Is there a way so I can easily include my websites header and footer into XF pages (using PHP include function)?
3. Previously I was using PHPBB as my forum on my website. And all the post are using bbcodes of PHPBB and now when I imported all the posts in XF the bbcodes are not supported here. How I can make them work?
