What function does the preview for the blog ?! (to trim blog posts)

[mihai11]

Hi,




When you enter someone's blog you will see a preview of his VB Blogs - usually the length of the preview is of 500 characters. What function does that ? I need to display the preview of some blogs on some other pages.


UPDATE:

What I did until now is this:

PHP Code:

$parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());
$blog_message_body = fetch_trimmed_title($parser->do_parse($blog_data['pagetext']), 500); 


The problem is that this version cuts the BB code anywhere, the result => invalid HTML code in the broswer !

Does anybody know how to solve this elegantly ?

Razvan
