Code

function shoutbox_display_posts($show_amount, $wrap = TRUE, $pager = FALSE) {
  $rows = array();
  $raw = array();
  $contexts = array();

  // Figure out if we should display it in ascending or descending order.
  $ascending = variable_get('shoutbox_ascending', TRUE);

  // Determine the shout context
  shoutbox_invoke('context', $blank, $contexts);

  // Allow other modules to alter the query
  $query = db_rewrite_sql("SELECT shoutbox.* FROM {shoutbox} shoutbox ORDER BY created DESC", 'shoutbox', 'shout_id', $contexts);
  if (!$pager) {
    $result = db_query_range($query, 0, $show_amount);
  }
  else {
    $result = pager_query($query, $show_amount, 1);
  }
  while ($shout = db_fetch_object($result)) {

      // Filter shout
      _shoutbox_sanitize_shout($shout);

      // Add edit/delete links depending on user's permissions.
      $shoutlinks = _shoutbox_get_links($shout);

      // Allow other modules to alter the shout before it's viewed
      shoutbox_invoke('view', $shout);

      // Theme the shoutbox post
      $post = theme('shoutbox_post', $shout, $shoutlinks);

      // Add themed rows
      $rows[] = array(
