php - hide price and add_cart for anonymous user in drupal -

how hide price , add_to_cart option anonymous users in drupal?

i think, can go page dmin/people/permissions , uncheck option anonymous.

to hide fields can create node--your_content_type.tpl.php

in template can check user-role:

global $user;  // check if user has 'authenticated user' role. if (in_array('authenticated user', $user->roles)) {   //show field  } 

also can hide css -)

.not-logged-in .your_class_field {display: none;}
