<?php

/**
 * @file

 *
 * Available variables:
 * $form - FAPI array
 *
 * All questions are in form[x] where x is an integer.
 * Useful values:
 * $form[x]['question'] - the question as a FAPI array(usually a form field of type "markup")
 * $form[x]['score'] - the users score on the current question.(FAPI array usually of type "markup" or "textfield")

  • Do you only want the quiz' NID, then arg(1) is all you need. But if you need the NID of the current question, then this answer may help you. – leymannx Sep 28 '15 at 12:47

Here is a very simple way to get the nid of the node currently being viewed:

$path = current_path();
list($entity_type, $entity_id) = explode('/', $path);

After this, you will have the entity id (the nid in the case of nodes) in the variable $entity_id.

  • Or menu_get_object()? (anything that avoids using the awful list() function goes in the win column for me). Bear in mind this will only work for nodes, and entities who specifically define their URI as entity_type/%, and entities whose URI callback function hasn't been overwritten to move the identifier within the path. It also won't work for entities like taxonomy terms, whose path is taxonomy/term/%. menu_get_object() is considered the best solution for nodes specifically. – Clive♦ Oct 1 '13 at 13:07
  • You are right, but since the OP specifically asked for an nid, IMO generic application isn't a high priority concern here. And since it will go into a template file, there is effectively 0 risk of a misfire. As for list(), I find it simple and concise. – Jovean Oct 1 '13 at 14:02

    Sure, there are quite a few ways to skin that particular cat - it's just menu_get_object() is the recommended one. – Clive♦ Oct 1 '13 at 14:22
