Embed a view of children onto a node.

Code

function nodehierarchy_views_embed_children(&$node) {
  static $depth = 0;

  // Make sure we don't go through more than 3 iterations to prevent memory or call stack errors.
  if ($depth++ < 3) {
    $display = @$node->nh_children_view_display ? @$node->nh_children_view_display : 'default';

    // Get the arguments to send to the view. This should allow other view arguments to still work.
    $arguments = explode('/', $_GET['q']);

    // First arg will be 'node', the second will be the node id. Remove them.
    array_shift($arguments);
    array_shift($arguments);

    // Add the node id of the given node.
    array_unshift($arguments, $node->nid);

    // Defer the rendering of the view until the theme function so it can be overriden or altered.
