Say your new column is called "simon1", it will be available as $post[simon1] in the postbit templates. What I did is create a new template (I had a few lines for mine), say postbit_simon with the new values in there:
HTML Code:
<if condition="$post['simon1']>= '1'">$post[simon1] Threads in Simon's forum<br /></if>
Then I created a plugin using postbit_display_start to insert that line using a template hook:
PHP Code:
eval('$template_hook[postbit_userinfo_right] .= " ' . fetch_template('postbit_simon1') . '";');
If you only have the one line in the template, you can probably just do it directly in that plugin:
PHP Code:
if ($post[simon1] >= '1') {
eval('$template_hook[postbit_userinfo_right] .= "$post[simon1] Threads in Simon\'s forum<br />";');
}
(NOT tested, but it's something like that. html must be escaped properly if using that method.)
If you use that method, don't forget to also cache the template. (Well, you don't have to, but it's good practice.)
