I can use hook_links() to add a link to my node, but I don't know how to get that link displayed in the body except by manually adding it to the node_body in hook_view(), i.e.:

$node->body .= l($link[<link name>]['href'])

However, this doesn't handle $link properly when the format of the link is a "non-link" (i.e. w/o an href). What is the proper method for doing this?

          $links['pinkslip_author_link'] = array(
                'title' => t('See more articles from '.$node->name),
                'href' => "pinkslip/author/$node->name",
                'attributes' => array('title' => t('See more articles from '.$node->name)),
                'html' => FALSE
              );

The link shows up at the bottom of the node.

hat's the output from the hook_links() function.

Here's a snippet from product.module:

function product_link($type, $node = null, $teaser = false) {
drupal_set_message(t('snhp->product_link(): $node->ptype == %a', array('%a'=>$node->ptype)),'error');
  $links = array();

  if ($type == 'node' && $node->ptype) {
    /* Determine whether or not the 'add to cart' link needs to be displayed. */
    $item = module_invoke('cart', 'get_items');
    if (variable_get('product_cart_addition_by_link', 1) && $node->hide_cart_link == 0) {

      /* Right here we need to check if a given product type is in stock */
      if (product_get_attributes($node, 'in_stock') !== false) {
      <deleted...>
        }
        else {
          $links['add_to_cart'] = array(
            'title' => t('Add to cart'),
            'href' => "cart/add/{$node->nid}",
            'attributes' => array('class' => 'cart_link', 'title' => t('Add this item to your shopping cart.')),
            'query' => variable_get('product_cart_is_destination', 0) ? NULL : drupal_get_destination()
          );
        }
      }
      else {
        $links['add_to_cart'] = array(
          'title' => t('Sold out'),
        );
      }
    }
  }
  return $links;
}

But what do you mean that it automatically shows up at the bottom of the node?

Actually, I should clarify that the place I want it to show up is in a view of the node, which is why I am messing with $node->body and $output from above. If I'm putting the link in a view, should it also automatically show up?

Since I don't use hook_view, the standard node presentation places the links at the bottom of the display of the node. But I would think that any view presentation would include them. Take a look at how the node module does it and compare it to yours.

The links are typically printed in node.tpl.php something like this

<?php
  if ($links) {
    print $links;
  }
?>

While often after the content you can also place them before the content.

The output, $links = hook_links(), is an array. is this the same $links that you can simply print in node.tpl.php?

You have to theme the output from hook_links() to get it to display it properly:

So in hook_view() for the module in question, I just added:

        $link_array = hook_link('node', $node);
        $node->body .= theme_links($link_array);
        $output .= check_markup($node->body);

Thanks for the tip on node.tpl.php, it got me thinking in the right direction.
