Problem accesing WordPress within my PHP app

Hi!

I’m accessing the WordPress API from within my PHP code just including the wp-blog-header.php and using get_posts().

This is working ok when my PHP code is at the same level than the WP directory. For example:

/index.php
/blog/[..wp files..]

At index.php, I have:

require(‘blog/wp-blog-header.php’);
$post = get_posts(…);

and is working pretty well.

BUT, when I try to do the same with the code inside a directory, for example:

/blog/[..wp files..]
/folder/index.php

and at folder/index.php I have:

require(‘../blog/wp-blog-header.php’);
$post = get_posts(…);

this always makes my app to redirect to the WP installation (wp-admin/install.php) and doesn’t work.

Any idea ? Can the API be used from within a directory ?

The blog is configured correctly and is working ok by itself.

Thanks!
