set which node types to protect.

At the moment we can not select for which node types (content types) we want to offer node protection.

There are guys they are realizing that by a cck filed. For that see: http://drupal.org/project/password and this feature request: http://drupal.org/node/126129

I've solved this problem by adding a settings page where you can select the node types. And then I changed the hook_form_alter:

// check if this node type should be protected
$types_to_protect = variable_get('protected_node_nodetypes');

if (!in_array($form['type']['#value'], $types_to_protect)) {
  return;
}

and

hook_nodeapi

$types_to_protect = variable_get('protected_node_nodetypes');
	
if (!in_array($node->type, $types_to_protect)) {
  return;
}

I hope that's all. :)
