仅当个人资料所有者不属于角色X时才显示内容（在Drupal 7中）

Question

I have a Drupal 7 site, and I would like to print out inside the profile page some field content, according to the role of the profile user (not the logged in user). I need to show a specific field only if the profile owner does not have role autor:

<?php
  if (!in_array('autor', array_values($user->roles))) {
print drupal_render(field_view_field('profile2', $profile['main'], 'field_nombrecompleto1', 'value'));
  }
  else {print "yada yada";}

Note: The profile field in question, is a rofile2 field and not a core profile one.

What´s wrong with that code? Because it will print out the field in question in any case, regardless of the role of the profile owner.

I´ve tried this other code, and in this case the field won´t print out in any case:

<?php
if (is_array($user->roles) &&
    in_array('authenticated user', $user->roles) &&
    !in_array('autor', $user->roles)) {
    print drupal_render(field_view_field('profile2', $profile['main'], 'field_nombrecompleto1', 'value'));
}
?>

Here is how this is accomplished in Drupal 7 when modifying the form for editing your profile:

function MYMODULE_form_profile2_edit_main_form_alter(&$form, $form_state) {
  global $user;
  $roles = $user->roles;
  if(!in_array('authenticated user', $roles)) {
    $form['profile_main']['MY_FIELD_ID']['#access'] = FALSE;
  }
}
