Well, there are quite some differences difference between the results
these two pieces of code yield. Let's see what your sql query would be
for the first version, replacing $deposit in $query:
Advertising
UPDATE wt_users set bank_points + $user_depositset points - $user_deposit WHERE
uid={$session["uid"]}
^1 ^2 ^3
whereas we probably want
UPDATE wt_users set bank_points=bank_points + $user_deposit, points=points -
$user_deposit WHERE uid={$session["uid"]}
I marked the three problems in your original code (you'll want to use a fixed
character to see them properly):
1. set who to this value?
2. There must be a space there
2bis. set and set don't go well together - we want a comma instead
3. same as 1
OTOH, you may want to get rid of those brackets in $query=("...") - they
really don't do anything...
