If else statement

[3littlepigs]

HELLO! 🙂

I require some help with my codes. The if query in the following codes does not work. Can anyone help me to identify where i went wrong?
THANKYOU!😉

$rthings = mysql_query('SELECT uid,itemid FROM inventory');
$things = mysql_fetch_assoc($rthings);

if ($_GET["operation"]==1){
$query = 'UPDATE Person SET wealth = wealth-5 WHERE uid = '.$uid;
mysql_query($query) or die(mysql_error());
if ($things['uid']==$uid $$ $things['itemid']==1){
$query = 'UPDATE inventory SET quantity = quantity+1 WHERE uid=".$uid." && itemid ="1" ';
mysql_query($query) or die(mysql_error());
echo "updated";
}else{
$query= 'INSERT INTO inventory (uid,itemid,quantity) VALUES ('.$uid.', 1, 1)';
mysql_query($query) or die(mysql_error());
echo "inserted";
}

Currently, only the insert into query works, thus whenever I press button with operation==1, there will be a new row inserted in our database table but the quantity is not updated

You've started two if-statements (row 1 & 4) but only closed one of them (row 8).

What happens if you run error_reporting(E_ALL) in the beginning of your PHP file?

We aren't psychics. You tell us.

1. Read code syntax formatting
2. Tell us what the error is, or what you want to do and what actually happens
3. Post any php error messages, and indicate where in the posted code those lines are.
4. For any assignments done outside your script that are relevant for the problem at hand, include information as necessary about what those variables contain and/or how and where they are assigned.
