How to integrate WordPress template with CodeIgniter

Question

How can CodeIgniter and WordPress be integrated such that the look and feel/template of the WordPress blog is carried over to the CodeIgniter-created pages?

Answer 1

First step is to move CodeIgniter and the WordPress files in their own directory.

After that, put the following line at the top of your CodeIgniter's index.php file. Change the path to wp-blog-header.php as needed to point to your WordPress's root directory.

<?php
    require('../wp-blog-header.php');

Then, you can use the following functions inside your views:

<?php
    get_header();
    get_sidebar();
    get_footer();    
?>

Other helper functions can also be found in WordPress's documentation which can assist you in integrating the design.
