Limitare numero nodi per un content type

Ciao, usa node_limit

Dovresti cambiare la funzione validate alla riga 206.
Ad esempio nel node limit 7.x-1.0-alpha5+5-dev controlla il content type page:

/**
* Implements hook_node_validate().
*/
function node_limit_node_validate($node, $form, &$form_state) {
  if (empty($node->nid) && _node_limit_violates_limit($node)) {
    //we have a violation!
    //and this is a new node
    $nodetype = node_type_get_type($node);
    form_set_error('title', t("You can't create more content of type !type", array('!type' => check_plain($nodetype->name))), 'error');
  }
 
  // For now assign the static values to CONENT_TYPE and MAX_NODES
  // however you can make it dynamic, and get those values using variable_get()
  // or costant define("MAX_NODES", 200); define("CONTENT_TYPE", 'page');
  $content_type = variable_get("node_limit_node_content_type", "page");
  $max_nodes = variable_get("node_limit_node_maxnode", 1000);
  $node_count = 0;

  // Create a check for the content type.
  if ((isset($node->type)) && ($node->type === $content_type)) {
    $query = new EntityFieldQuery;
    $node_count = $query->entityCondition('entity_type', 'node')
      ->entityCondition('bundle', $content_type)
      // To get published nodes only, use: ->propertyCondition('status', 1)
      ->count()
      ->execute();

    // Check if the node count exceeds the max_node value.
    if ($node_count > $max_nodes) {
      form_set_error('FIELD_NAME', t('Reached the maximum limit of creation of nodes for this content type.'));
    }
  }
}

Poi il file info diventerebbe 7.x-1.0-custom per evitare sovrascritture con gli update. Decidi tu se ti va bene.

Ti ringrazio molto.
