Ubercart show Prices without Tax For specific Role

Question

I need to show prices without tax for specific user role. Other available roles should see prices with included tax. How I can achieve this behavior?

Answer 1

ubercart adds taxes in hook_entity_view_alter( uc_taxes_entity_view_alter)

So I implement hook_entity_view_alter in my module

function mymodule_entity_view_alter(&$build, $entity_type) {
  global $user;

  if($user && in_array(constant('SOME_USER_ROLE'), $user->roles)) {
    return;
  } 

  // ...
}

Also unimplement uc_taxes implemetation of hook_entity_view_alter using hook_module_implements_alter

function mymodule_module_implements_alter(&$implementations, $hook) {
  if (in_array($hook, array( 'entity_view_alter'))) {
    unset($implementations['uc_taxes']);
  }
}
