Hey Mark,

We actually plan on adding multi-site support in the next few version updates. That will be unlikely to happen for a couple of months though.

Fail, just answered my own post ??

This can be resolved by using a simple PHP function called “nl2br” which basically means it will convert carriage returns (that means a text line break) into the correct HTML linebreak format, br.

To do it, you can simply use echo nl2br($curauth->description); in order to display an Author Bio complete with HTML Linebreaks.

I’m sure there is, the point of this post was that it should either be standard or a security option by standard.

Damn, Google pulled through for me a little too late.

This is badly documented, but appending get_ to the beginning of a template tag will return it rather than echoing it.

Therefore…

foreach ($comments as $comment) {
   $get_comment_id // Will return the ID, but not print it to the page
   $comment_id // Will print it to the page, rather than return it.
}

In the end I had to hack this out to make sure no one could do it any longer.

After line 38 of “wp-comments-post.php” add this:

// get list of user (display) names for blog
global $wpdb;
$valid_users = (array)$wpdb->get_results("
  SELECT display_name, user_email FROM " . $wpdb->prefix . "users");

// get ID of logged in user (if there is one)
global $userdata;
get_currentuserinfo();
$logged_in_name = $userdata->ID;
$logged_in_email = $userdata->user_email;

// see if the comment author matches an existing author
$found_match = FALSE;
foreach ($valid_users as $va) {
  if (trim($va->display_name) != '') {
    if (strtolower($va->display_name) == strtolower($comment_author)) {
      $found_match = TRUE;
      break;
    }
  }
  if (trim($va->user_email) != '') {
    if (strtolower($va->user_email) == strtolower($comment_author_email)) {
      $found_match = TRUE;
      break;
    }
  }
}

// if commenter is not logged in, but match was found, block the comment
if (trim($logged_in_name) == '') {
  if ($found_match == TRUE) {
    wp_die( __('You cannot post using the name or email of a registered author.') );
  }
}

You can add in your own way of doing the error message.

@claytonjames – don’t be so naive, it’s rather easy to get hold of blog posters email addresses, particularly in the open social worldwide web.
