Is it possible to request the url 'node-alias/subpage'?

By timonweb on 25 Feb 2010 at 12:01 UTC

I'm developing a module, something similar to Talk module, which allows to have reviews or comments on a separate page, not on the bottom of a node page. As you may know, even if your node has an alias like: http://example.com/great-film, its talk page url will look like: http://example.com/node/1/talk ... but I want to make it accessible via http://example.com/great-film/talk ...

I tried to create hook_menu like this:

$items['%/talk'] = array(
'page callback' => 'talk_page',
'page arguments' => array(0),
'access callback' => 'user_access',
'access arguments' => array('access content'),
);

But it doesn't work. Pathauto won't help also, because '/talk' isn't a node, this is a custom url ... so my idea is to make Drupal somehow recognize '%/talk' slug (instead of % it should have node's alias) ... is it possible to do this somehow? Any ideas?

hook_pathauto + hook_nodeapi

first create menu item like $items['node/%node_id/talk']

then you can refer following code it will insert alias for your menu item when new node inserted.. please add check for your content type.

function custom_nodeapi(&$node, $op, $a3, $a4)
{
  switch ($op)
  {
    case 'insert':
    {  
      /* 
  We create aliases here: 
      */

      $placeholders = pathauto_get_placeholders('node', $node);
      $nid          = $node->nid;
      $url          = "node/$nid/talk";

      pathauto_create_alias('custom', 'insert',  $placeholders, $url,
                            $nid, $type, $node->language);
      break;
    }
    case 'delete':
    {
      path_set_alias("node/$nid/talk");
      break;
    }
    
  }
}

function custom_pathauto($op = '')
{
  $pathauto = null;

  switch ($op)
  {
    case 'settings':
    {
      $header     = t("Custom Path For Node talk Pages");
      $pattern    = t('Default path pattern for talk.');
      $bulk       = t(  'Bulk generate aliases for talk');
      $bulkDesc   = t(  'Generate aliases for all existing node ');
      $patterns   = token_get_list('node');
      $languages  = array ( );

      foreach ($patterns as $type => $pattern_set)
      {
        if ($type != 'global')
        {
          foreach ($pattern_set as $pattern => $description)
          {
            $placeholders["[$pattern]"] = $description;
          }
        }
