possible to embed comments on my custom profile page (using node_load to get usernode fields)

What do you mean by custom profile page?

Thanks for your private message, that helped a lot!

Usually the usernode_guestbook is rendered inside a normal, untouched profile-page.

As I understood your local approach, you don't use this, because you load several nodes into into your custom styled user_profile.tpl.php

You can render the usernode's comment box if you use the function usernode_guestbook_box($account); where $account is the user object of the user whose profile page is to be displayed. Note: The API has changed, the function was called usernode_guestbook_usernode($account) until revision 1.2.

Please reopen this issue if you need further help on it.

Sorry for reopening this, but what is the code I would use in my custom user_profile.tpl.php. Actually I would prefer to use it in a block if at all possible. This is what I posted in my template.php, is that correct to override the function?

function phptemplate_usernode_guestbook_box($account) {
  $node = usernode_get_node($account);
  $output  = '';
  switch ($node->comment) {
    case COMMENT_NODE_READ_WRITE: // 2
      $output .= comment_form_box(array('nid' => $node->nid), NULL);
    case COMMENT_NODE_READ_ONLY:  // 1
      $output .= comment_render($node);
      break;
    case COMMENT_NODE_DISABLED:   // 0
    default:
      $output .= t('@name\'s @guestbook is currently deactivated.', _usernode_guestbook_translations(check_plain($account->name)));
  }
  // Update the history table, stating that this user viewed the usernode.
  node_tag_new($node->nid);
  return $output;
}

Thanks for assisting,

I thought the following should work but it doesn't.

In template.php

function phptemplate_usernode_guestbook_box($account) {
	return _phptemplate_callback('usernode_guestbook_box', array('account' => $account));
}

In user_profile.tpl.php

print $account;

I'm kinda guessing how these theme overrides work, so it's no surprise it's not working. I really need to show the comments on my custom profile page with the comment post box. This module is exactly what I'm looking for, but without a solution for my profile page, I'm doomed. Any further help please?

Thanks a ton Lausch...I have to admit, much of this php is abracadabra to me. So I took your code and together with the following line I stuffed it in a block like so:

global $user;
print usernode_guestbook_box($user->uid)

However that shows my comments on everybody's profile page, since I'm considered the current logged in user. What argument do I need to include to make it so it shows the users own comments?

Thanks in advance,
Marius

Right...I failed to explain that without that line it fails to load the usernode guestbook properly for the user and returns "anonymous's guestbook is currently deactivated." So I used some code from another block and now it works perfect. Thanks for pointing me in the right direction. This is the added code to activate the user from a block:

$uid = arg(1);
$user = user_load(array('uid' => $uid));
print usernode_guestbook_box($user->uid)

i'm wondering what is the result!?

best regards

i can write a comment, but the lines below the inputfield are not working/not collapsible...

$uid = arg(1);
$user = user_load(array('uid' => $uid));
