I have a URL alias sitepath/john/video/nature-beauty where john = user, video = content type and nature-beauty = node. I am trying to get nid of node nature-beauty. Node title is "Nature beauty" actually. I have set node title in URL alias.

Can anyone tell me where am I wrong in below code?

   $last_page_visited = $_SERVER['HTTP_REFERER'];
   $alias =$last_page_visited;
   $path = drupal_lookup_path("source", $alias);
   $node = menu_get_object("node", 1, $path);
   $nid=$node->nid;
   print $nid;

The $_SERVER['HTTP_REFERER'] will return the full URL, but the function drupal_lookup_path() takes only the alias as argument, so parse you URL and pass only the alias, john/video/nature-beauty then it will work.

$url = $_SERVER['HTTP_REFERER'];
$path = preg_replace('/\//','',parse_url($url,PHP_URL_PATH),1);
$org_path = drupal_lookup_path("source", $path);
$node = menu_get_object("node", 1, $org_path);
$nid=$node->nid;
print $nid;

  • Yes and tried too. But after parsing url its displaying text "array" as parsed url. – D-pak Jun 25 '14 at 6:52
  • @D-pak how did you parse?, which function you used – wolverine Jun 25 '14 at 6:53
  • Here it is $parsed=drupal_parse_url($last_page_visited); – D-pak Jun 25 '14 at 6:58

    drupal_parse_url() will return an array containing path,query etc. Try preg_replace('/\//','',parse_url($_SERVER['HTTP_REFERER'],PHP_URL_PATH),1); – wolverine Jun 25 '14 at 7:11
  • @wolverine Please update your answer(by including code) so that it would be more clear for future readers :) – Krishna Mohan Jun 25 '14 at 9:37

There are number for of ways to get nid but its depend how your page is build. If its a direct node page then you can get using $_GET["q"] or using arg() function. You can also use menu_get_object() function directly and get the $nid=$node->nid;.

  • $_GET["q"] would return like node/2345 2345 is your node nid.
  • arg(1) would return node nid.

  • After using $_GET["q"] its giving correct answer. But how to do it with last visited page url? – D-pak Jun 25 '14 at 6:41

There is nothing wrong in your code. Just use drupal_get_path_alias instead of $_SERVER['HTTP_REFERER']; to get url alias.

If you want to use $_SERVER['HTTP_REFERER'] you need to parse the it like follows.

   $path = $_SERVER['HTTP_REFERER'];
  $filter = preg_replace('/\//','',parse_url($path,PHP_URL_PATH),1);
   $path = drupal_lookup_path("source", $filter);
   $node = menu_get_object("node", 1, $path);
   $nid=$node->nid;
   print $nid;

  • I am trying to get nid from the previously uploaded node url. And that's why i have written $_SERVER['HTTP_REFERER']; – D-pak Jun 25 '14 at 6:09
  • @D-pak Sorry for late response, I've updated my answer – Krishna Mohan Jun 25 '14 at 7:46
  • Yes I have written same code before and it works fine, Thanks. – D-pak Jun 25 '14 at 8:24

$path = drupal_get_path_alias($_GET['q']); 
$path = explode('/', $path);
echo $nid = $path[1];

Or simply arg(1) will return the node id of the page By using this, you can get the nid of any node. But it should be the detail page of any node

  • did you check my answer – wolverine Jun 25 '14 at 6:48
  • Yes and tried too. But after parsing url its displaying text "array" as parsed url. – D-pak Jun 25 '14 at 6:53
  • I have made some modification in the code, its working example – TBI Infotech Jun 25 '14 at 14:35

global $base_url;
$referrer = substr($_SERVER['HTTP_REFERER'], drupal_strlen($base_url));
$referrer = drupal_get_normal_path($referrer);
$referrer = trim($referrer, '/');
if (arg(0, $referrer) == 'node' && is_numeric(arg(1, $referrer)) {
  $nid = arg(1, $referrer);
}

That's it. $base_url includes subdirectory, if your site is not in server root: http://example.com/drupalsite. drupal_get_normal_path transforms alias into drupal internal path, that is, article/marvelous into node/101. It is actually a wrapper around drupal_lookup_path, so the use of the latter is discouraged. And then you get your nid.
