Getting nodes and display a list

Submitted by AjK on 9 October 2008 - 3:00pm

This article focuses on one of the main reasons applications are rejected, that it acquires a list of nodes and renders some sort of output to the browser. It's a common task often seen and often done totally wrong.

So, by example, lets look at a snippet of often seen code that's reviewed and rejected and then we'll break it down and examine each point.

  1. function foo() {
  2.   $sql = "SELECT nid, title FROM {node} WHERE type = 'foo'";
  3.   $result = db_query($sql);
  4.   while ($row = db_fetch_array($r)) {
  5.     $output .= '<li><a href="node/'.$row['nid'].'">'. $row['title'].'</li>';
  6.   }
  7.   return $output;
  8. }
