"Add location from node view" functionality. Split from main location.module in version 3.

Code

function location_addanother_form_validate($form, &$form_state) {

  // Load the stored node from form_state.
  $node = $form_state['#node'];

  // Load the content type's location settings to see if addanother is enabled.
  $settings = variable_get('location_settings_node_' . $node->type, array());
  $is_enabled = isset($settings['multiple']['location_addanother']) ? $settings['multiple']['location_addanother'] : FALSE;

  // If addanother isn't enabled for this node type,
  // or there's too many locations,
  // or the user doesn't have access to add a location,
  if (!$is_enabled || count($node->locations) >= variable_get('location_maxnum_' . $node->type, 0) || !node_access('update', $node)) {

    // then give a useful error.
    form_set_error('location', t("You don't have permission to add a location to this node, or the node has the maximum number of locations already."));
