only buddies can see profile

No.

I needed something like that on a previous project and had to write some custom code. Here is the overview of what I did.

1. I created fields using core profile module - for the ones I didn't want non-buddies to see I made them Private field, content only available to privileged users.
2. In access control all users are granted the permission access user profiles
3. Next I wrote custom code for hook_profile_alter that checked to see if the currently logged in user was a buddy of the $account being viewed. If so, I showed all "private" fields, if not I removed those from the profile view.

Here is the function for checking the "if buddy".

function _buddylistext_is_buddy($uid,$bid) {
  $isbuddy = db_result(db_query("SELECT * FROM {buddylist} WHERE uid = %d AND buddy = %d",$uid, $bid));
  return $isbuddy;
}

Maybe some version of this will be helpful for you.

You need to create a custom module to hold this code - don't worry its easy.

make a folder called omnyx in sites/all/modules/custom/
create a file call omnyx.info and put this code in it

name = omnyx
description = Change profile handling and other site modifications

then create file called omnyx.module and put this code in it.

<?php
function omnyx_profile_alter($account, &$fields) {
  global $user;

  drupal_set_message("WELCOME OMNYX=>" . drupal_to_js($fields));
  
  //HERES WHERE YOU COULD MAKE THE IS BUDDY CHECK - HARD CODED NOW
  $show_private = TRUE;
  
  if ($show_private) {
    $result = db_query('SELECT * FROM {profile_fields} WHERE visibility IN (%d)', PROFILE_PRIVATE);
    while ($field = db_fetch_object($result)) {
      // Mark the private field as public temporarily
      $field->visibility = PROFILE_PUBLIC;
      // Call profile module to format it
      if ($value = profile_view_field($account, $field)) {
        $title = ($field->type != 'checkbox') ? check_plain($field->title) : NULL;
        $item = array('title' => $title,
          'value' => $value,
          'class' => $field->name,
        );
        $fields[$field->category][$field->name] = $item;
      }
    }
  }
}

then enable the module on the modules page. Visit a user/X page and the private profile values should show up. You can customize the code to make the showing of the private fields based on the buddylist relationships of the users as mentioned before.

White screen is usually a php error of some kind. Check your various apache log files - they might help track it down.

If you called the files buddyonly you need to replace omnyx with buddyonly in your functions - the name of the module is used to figure out the function names for hooks.

I tested the module under php 5 but I don't think anything is requiring php 5 in that code.

You can't have a function inside a function.

You need to move the _buddylistext_is_buddy function outside of the profile_alter function. The white screen is from a PHP error but you don't have error messages enabled (usually a good thing for a production server) so you aren't seeing the error.

That's my guess anyway.

function buddyonly_profile_alter($account, &$fields) {
  global $user;

// drupal_set_message("WELCOME OMNYX=>" . drupal_to_js($fields));
// I needed to comment the upper line because it was listing the fields in error...is it ok if it's commented?

  function _buddylistext_is_buddy($uid,$bid) {
  $isbuddy = db_result(db_query("SELECT * FROM {buddylist} WHERE uid = %d AND buddy = %d",$uid, $bid));
  return $isbuddy;
}

$isbuddy = _buddylistext_is_buddy($user->uid, $account->uid);

$show_private = FALSE;
if($isbuddy) { $show_private = TRUE;}

  if ($show_private) {
    $result = db_query('SELECT * FROM {profile_fields} WHERE visibility IN (%d)', PROFILE_PRIVATE);
    while ($field = db_fetch_object($result)) {
      // Mark the private field as public temporarily
      $field->visibility = PROFILE_PUBLIC;
      // Call profile module to format it
      if ($value = profile_view_field($account, $field)) {
        $title = ($field->type != 'checkbox') ? check_plain($field->title) : NULL;
        $item = array('title' => $title,
          'value' => $value,
          'class' => $field->name,
        );
        $fields[$field->category][$field->name] = $item;
      }
    }
  }
}

Drupal core calls hook_profile_alter everytime a profile is being viewed and passes the $account information being viewed. "Hooks" are called by looking at every module loaded for a function called "modulename_hook_name" so in this instance 'buddyonly_profile_alter'. Other modules could also provide a profile_alter hook.

I hope this gets it working for you.

The fields are only made public locally during this function call and won't have any effect on other users viewing the same profile.

The chunk of code you are wondering was taken from the profile.module and simply builds the html for each profile field you are showing based on its type, etc. and adds it into the array of things to display. That is, the return value of the profile_alter function is a structured array of all the items that will be displayed on the rendered page.

Glad its working and hope you learned some stuff along the way.

Because I'm altering the local copies of the profile fields and data - not the database.
