File

An alternative node previewing system for the node add/edit form.

Code

function pagepreview_render_preview($node) {
  if (node_access('create', $node) || node_access('update', $node)) {

    // Load the user's name when needed.
    if (isset($node->name)) {

      // The use of isset() is mandatory in the context of user IDs, because
      // user ID 0 denotes the anonymous user.
