Abstract

The approach described here is intended to create an overview of the hierarchy of a taxonomy & showing the related nodes. The layout of the nodes is defined by the associated view (see below). This could be useful e.g. for a list of all downloads of a page.

Example

Term 1 with Depth 0

• node one of term 1, layout depending on view-settings
• node two of term 1, layout depending on view-settings
• etc., number depending on view-settings

Term 2 with Depth 0

  Term 3 with Depth 1, child of Term 2

• nodes of term 3, layout depending on view-settings

Term 4 with Depth 0

• nodes of term 4, layout depending on view-settings

  Term 5 with Depth 1, child of Term 4

• nodes of term 5, layout depending on view-settings

Steps to be taken

1. The Vocabulary

Create a new (optional: hierarchically) taxonomy or use an existing taxonomy. Remember its ID. It will be inserted in the PHP snippet shown in step 3.

2. The View

Create a new view for the nodes that use the vocabulary of step 1. As Argument Type for this view, set Taxonomy: Term Name. Remember the views name. It will be inserted in the PHP snippet shown below.

3. The php Snippet

This snippet is for Drupal 5 and views 1. For Drupal 6 and views 2 see comment of stone_d below.
Create new content or use existing content with PHP as input format. Then paste the following code and enter your values of step 1 & 2 in lines 2 & 5:

/* Enter the ID of the vocabulary which terms you want to show as headlines */
$vocabulary_id = "0";

/* Enter the name of the view that should show the nodes */
$view_name = "YOUR_VIEW";


/* Only edit if you know what you're doing */
$view = views_get_view($view_name);
if (!$view) {
    drupal_not_found();
    exit;
}
foreach(taxonomy_get_tree($vocabulary_id,0,-1,1) as $value) {
  print t("<div style='margin-bottom: 4em;'><h3>" . $value->name . "</h3>");
  print views_build_view('embed', $view, array($value->name), FALSE, $view->nodes_per_block);
  if ( taxonomy_get_children($value->tid) ) {
     print t("<div style='margin-left: 2em;'>");
     foreach( taxonomy_get_children($value->tid) as $child ) {
        print t("<h4 style='margin-top:2em;'>" . $child->name . "</h4>");
        print views_build_view('embed', $view, array($child->name), FALSE, $view->nodes_per_block);
      }
      print t("</div>");
  }
  print t("</div>");
}

Known issues

• Currently the code only support terms of the first two depths (the modifications to support unlimited depths shouldn't be hard to do)
• Hard coded CSS styles: I suggest to exchange them with your CSS classes.
