content_load(&$node)

Load data for a node type's fields. Implementation of hook_nodeapi 'load' op.

When loading one of the content.module nodes, we need to let each field handle its own loading. This can make for a number of queries in some cases, so we cache the loaded object structure and invalidate it during the update process.

<?php
function content_load(&$node) {
  $cid = 'content:'. $node->nid .':'. $node->vid;
  if ($cached = cache_get($cid, content_cache_tablename())) {
    foreach ($cached->data as $key => $value) {
      $node->$key = $value;
    }
  }
  else {
    $default_additions = _content_field_invoke_default('load', $node);
    if ($default_additions) {
      foreach ($default_additions as $key => $value) {
        $node->$key = $value;
