Implementation of hook node_update().

Performs actions after any node has been updated.

File

tripal_example/includes/tripal_example.chado_node.inc, line 732

This file should contain all Drupal hooks for interacting with nodes.

Code

function tripal_example_node_update($node) {

  // EXPLANATION: This function is used after any a node is updated in the
  // database. It is different from the hook_update() function above in that it
  // is called after any node is updated, regardless of it's type.
  // An example comes from the tripal_feature module where the URL alias of a
  // node cannot be set in the hook_update() function. Therefore the
  // tripal_feature module uses this function to reset the URL path of an
  // updated feature node.
  //
  // This function is not required. You probably won't need it if you don't
  // define a custom node type in the hook_node_info() function. But it is node
  // type agnostic, so you can use this function to do any activity after insert
  // of a node.

  // add items to other nodes, build index and search results
  switch ($node->type) {
    case 'chado_example':

      // If your module is using the Chado Node: Title & Path API to allow
      // custom titles for your node type. Every time you want the title of the
      // node, you need to use the following API function:
      $example->title = chado_get_node_title($node);

      // set the URL for this example page
      // see the code in the tripal_feature/includes/tripal_feature.chado_node.inc
      // file in the function tripal_feature_node_insert for an example of how
      // that module sets the URL. It uses a configuration file to allow the
      // user to dynamically build a URL schema and then uses that schema to
      // generate a URL string.
      break;
