Getting the URL of a node in Drupal 7

Question

Goal: To send an email with a list of URLs generated from nodes.

In my custom module I have managed to get the node id which the user wants and I now want to get the URL of each node to put into my email.

I searched the db and used google but I can't seem to find the right solution.

It seems we need to construct the URL something like this:

<?php
global $base_url;
$link=$base_url."// few more parameters 

Answer 1

You can use the url() function:

$options = array('absolute' => TRUE);
$nid = 1; // Node ID
$url = url('node/' . $nid, $options);

That will give you the absolute path (i.e. with http://example.com/ in front of it), with the URL aliased path to the node page.
