Question

I am not sure if this is an issue with my current setup, or what I want to do.

I have a module that is programatically creating nodes in my Drupal 6 site, and within each I have to provide links in between various nodes.

I basically have a few foreach loops, and within each I have the current path.

For instance:

foreach ($page->category as $category) {
  $category_link = "category/" . $category['id'];

  // generate category pages
  ...
  $content = "<a href='$category_link'>".$category['name']."</a>";
  _create_node($content);

  foreach ($category->article as $article) {
    $article_link = $category_link . "/article/" . $article['id'];

    // generate article page
    $content = "<a href='$category_link'>".$category['name']."</a>";
    $content .= "<a href='$article_link'>".$article['name']."</a>";
    _create_node($content);
  }
}

The issue that I’m seeing is that the link seems to be continually built up.
For instance, in the main category pages it is fine (I’ll see category/1234), and the article link will be fine, but the category link will seem to be longer than it should. Basically, I’ll end up seeing:

category/1234/article/5678/category/1234

My first thought was to make use of $base_url and just create absolute paths, however whenever I try printing that variable from my module it is completely empty. This is on a local server, however when I move it to production Drupal isn’t installed at the root, so I can’t simply add a slash to the front of the link.

Try using $GLOBALS['base_path'] to get the base path.
