How do I print the edit link on a node page if the currently logged-in user has the permission to edit the node?

Question

I'm using Display Suite custom fields to have the edit link rendered somewhere else on the node page. Is there an easy way to verify the currently logged-in user has the permission to edit the node?.

So far I tried this code.

global $user;

if (node_access('update', $nid, $user)) {
  echo l(t('Edit this node'), 'node/' . $node->nid . '/edit');
}

What code should I instead use?

It might be that you don't have access to the node object, in which case changing to the following should work...

<?php 
  global $user;
  if ($node = node_load(arg(1))) {
    if (node_access('update', $node, $user) == true) {
      echo l(t('Edit this node'), 'node/' . $node->nid . '/edit');
    }
  }
?>
