query_posts('showposts=3');
?>
<ul>
<?php while (have_posts()): the_post(); ?>

Fatal error: Call to undefined method stdClass::set_prefix() in /blabla/blog/wp-settings.php on line 268

any idea what can be the problem? :/ appreciate helps!!

Answer 1

Have you thought about using the RSS feed from wordpress to display the blog posts with codeigniter? It would be a more flexible solution.

Answer 2

I've used 3 tricks for getting WordPress content into CodeIgniter:

1. Pull via XMLHttpRequest from a custom WP template (skip headers/footers/sidebars). I like this method as it is highly decoupled, and it makes for fast page loads.
2. Pull via CURL or get_file*. This is similar to using XMLHttpRequests, but server side.
3. Wrap WP in a library. This is more work, but the essence is calling the core WP object from a CI library. I prototyped this method last year, but found that #1 performed better (and it allowed me to move the content to another server later).

Note, you could also IFrame the page, but IFrames seem a bit hackish given #1 and #2.
