select data from db with forum permission active

[TitanKing]

Hello everyone, I hope I wont be to unclear about this, I need help desperatly, I need to take out info from say the thread table but with the forum permision still active. What I mean is say for instance I use the

PHP Code:

$DB_site->query_first( "SELECT title FROM vb3_thread WHERE threadid = "10"); 


Ok fine this is easy right, however how would I apply that only if the person has proper forum permision he would be able to view the title of say id 10...

I hope anyone has some info for me, I would appreciate it very very much !
