Implement the project node content type

Code

function chado_project_delete($node) {

  $project_id = chado_get_id_from_nid('project', $node->nid);

  // if we don't have a project id for this node then this isn't a node of
  // type chado_project or the entry in the chado_project table was lost.
  if (!$project_id) {
    return;
  }

  // Remove data from {chado_project}, {node} and {node_revisions} tables of
  // drupal database
  $sql_del = "DELETE FROM {chado_project} WHERE nid = :nid AND vid = :vid";
  db_query($sql_del, array(':nid' => $node->nid, ':vid' => $node->vid));
  $sql_del = "DELETE FROM {node_revision} WHERE nid = :nid AND vid = :vid";
  db_query($sql_del, array(':nid' => $node->nid, ':vid' => $node->vid));
  $sql_del = "DELETE FROM {node} WHERE nid = :nid AND vid = :vid";
  db_query($sql_del, array(':nid' => $node->nid, ':vid' => $node->vid));

  // Remove data from project and projectprop tables of chado database as well
  chado_query("DELETE FROM {projectprop} WHERE project_id = :project_id", array(':project_id' => $project_id));
  chado_query("DELETE FROM {project} WHERE project_id = :project_id", array(':project_id' => $project_id));
