Drupal: Add node content into block depending on page ID

/ Published in: PHP

Fairly simple way to match sidebar content with the main content for several pages without the need to create multiple blocks or the hassle of putting content in a block.

For example, your Home, About and Contact pages all have a sidebar with some accompanying content which is different for each.

1. Create pages (nodes) for each of the sidebar content and note the node ID.
2. Add a block and paste in this code snippet
3. Edit the Switch/Case part of this snippet for your nodes
4. Enable the block for content/* and node/*

Expand | Embed | Plain Text

Copy this code and paste it in your HTML

<?php
/**
* This code snippet is used to show selected node content
* in the block based on the current node id.  The idea is
* to show relevant sidebar content that matches up with the
* main content.  One block instead of several.
*
* If logged in user has admin nodes then show an Edit link.
*/
if ( arg(0) == "content" || arg(0) == "node" )
{
  //Choose which node to put into the block
  switch (arg(1))
  {
    case "10":  //nid of the home page
      $xNode = 58; //nid of content to load
      break;
    case "about":  //this page is a view made with Views module so no nid
      $xNode = 59;
      break;
    case "40":
      $xNode = 69;
      break;
    default:
      return FALSE;
  }
 
  $node = node_load($xNode);
 
  //Add an edit link for admins
  if (user_access('administer nodes'))
  {
    $nodeurl = url('node/'. $node->nid);
    print('<a href="'.$nodeurl.'">[edit]</a>');
  }
 
  $nodeout = node_view($node);
  print $nodeout;
 
}
 
/*  // Helpful debugging info.
$x=arg(0);
$y=arg(1);
$z=arg(1);
print "<p>x=$x<br />y=$y<br />z=$z</p>";
// ==End Debug==  */
