Update post before inserting to database (replace text during new post submit)

[lim(x?-5x?) = ∞]

Is it possible to replace text After user submitted new post, Before inserting to database. For example:

[url=http://www.mysite.com/forum/showthread.php?t=1234]something[/url]
[url]http://www.mysite.com/forum/showthread.php?t=1234[/url]
www.mysite.com/forum/showthread.php?t=1234

to

[thread=1234]something[/thread]
[thread]1234[/thread]
[thread]1234[/thread]

This is not about updating old posts in database via query, and not about bbcode parsing.

Is it possible to do with hooks? Is it possible with file edits? /includes/functions_newpost.php

May be someone knows hack or plugin with similar code?

Try using the hook location newpost_process. It's after vB sets the message but before it is saved. So, you can intercept it there and change it.
