function gnode_global_node_create_access in Group 7

Determines whether a user could create a node in a site-wide context.

This function does not take Group Node's hook_node_access() implementation into account. It just figures out if a user can create a node outside of any Group entity.

This is mostly useful because in order to have Node behave properly, we need to implement hook_node_access() just a little too permissive, making it hard to find out what rights the user had before we started interfering.

Parameters

string $type: The node type the user is attempting to create.

object $account: (optional) The account of the user.

Return value

bool Whether the user has creation rights.

1 call to gnode_global_node_create_access()

gnode_form_node_form_alter in modules/gnode/gnode.module

Implements hook_form_BASE_FORM_ID_alter().

File

modules/gnode/gnode.module, line 222

Contains Group's implementation of the Node module hooks and forms.

Code

function gnode_global_node_create_access($type, $account = NULL) {
  global $user;
  if (!isset($account)) {
    $account = $user;
  }

  // In order to figure out whether the user can create nodes outside of a
  // group, we first have to delete the cached node_access entry for this node
  // type.
  $rights =& drupal_static('node_access', array());
  unset($rights[$account->uid][$type]['create']);

  // Then we flag gnode_group_node_create_access() to not interfere with the
  // results of node_access() and run the latter to get the result we want.
  $skip =& drupal_static('gnode_group_node_create_access');
  $skip = TRUE;
  $return = node_access('create', $type);

  // After we have established whether the user has global node creation
  // rights, we need to once again unflag gnode_group_node_create_access() and
  // remove the node type's (skewed) entry from the node_access() cache.
  $skip = FALSE;
  unset($rights[$account->uid][$type]['create']);

  // After all this, it is safe to return the retrieved result.
  return $return;
