update two tables at once

I'm using 5.1.41-3ubuntu12.10 for my MySQL version.

UPDATE profiledata SET aboutyou = '$aboutyou', quotes = '$quotes' 
WHERE uid = '$sess_uid'

and 

UPDATE profileprivacy 
SET aboutyouPrivacy = '$aboutyouPrivacy', quotesPrivacy = '$quotesPrivacy' 
WHERE uid='$sess_uid'

$sess_uid is the same for both. I was wondering if I could combine both MySQL queries into one mysql_query.

I was thinking it would be something like SET profiledata.aboutyou = 'Just a developer.', not really sure.

MySQL does have multi-table update support: http://dev.mysql.com/doc/refman/5.0/en/update.html.

UPDATE profiledata, profileprivacy 
SET aboutYou = ..., aboutyouPrivacy = ... 
WHERE (profiledata.uid = $sess_uid) OR (aboutyouPrivacy.uid = $sess_uid)

or something similar should do the trick.

You can use a join like this:

$query = "UPDATE profiledata t1 
JOIN profileprivacy t2 ON (t1.uid = t2.uid) 
SET t1.aboutyou = '$aboutyou', 
    t1.quotes = '$quotes', 
    t2.aboutyouPrivacy = '$aboutyouPrivacy', 
    t2.quotesPrivacy = '$quotesPrivacy' 
WHERE t1.uid = '$sess_uid'";
