For a while now, I've been trying to figure out how to use WordPress functions outside of the WordPress directory (i.e. in a different folder). I just found a few posts about it on some WordPress Support pages (1, 2, 3, 4). All you need to do is add this line of code to a PHP file:
<?php require($_SERVER['DOCUMENT_ROOT'].'/your-wordpress-directory/wp-blog-header.php'); ?>
After this statement is added, you can call any WordPress function. For example, if you wanted to include WordPress headers and footers and the sidebar on a template in your Zenphoto installation, you would just need to include the file mentioned above and use the standard WordPress functions (get_header(), get_sidebar(), get_footer()).
Note: $_SERVER['DOCUMENT_ROOT'] is a call to your site's root directory (www.domain.com is the root of www.domain.com/blog/). I'm not sure if it works everywhere, but it works for me. #technology |
is_404()WordPress function outside the WordPress directory: It was returning "true", meaning it thought it was encountering an error. I think it has something to do with what Andy Skelton said abouthave_posts()andis_404()being mutually exclusive. If there are no posts, it returns a 404 error. I'm assuming this would also happen when the_loop isn't in use and/or if WordPress is used outside its main directory, which is the case in this instance. The way around this is to create an exception: Use some other method to identify a page outside of WordPress. For example, in my case, I saidif(basename(getcwd()) == 'pic') {do stuff} elseif(is_404()) {do other stuff}. In other words, if the last part of the URL is 'pic', perform an action. Otherwise, treat a 404 as a normal 404.The ZenPhoto support forums have some of the same information about integrating ZenPhoto with WordPress, but they suggest editing the main index.php file, whereas I edited each of the theme files (index.php, album.php, image.php). My way works; I would assume theirs does as well.
