won't add

[nabeels786]

    $result = mysql_query("SELECT * FROM gallery WHERE id=$id");
            while($row=mysql_fetch_array($result)){
                $numvotes = $row['numvotes'] + 1;
                $newrating = $row['rating'] + (int)rating;//thisline
                $newrating /= $numvotes;
                echo "$numvotes  $newrating  $rating  $row[rating] <br>";
            } 

"thisline" refuses to add, i can't figure out why

rating is passed through GET. $row[numvotes] + 1 adds fine
i tried casting it, thinking that would solve it, doesnt work either

Wait...

I'm not understanding the (int)rating thing. Should it be (int)$rating?

I'm thinking just plain old $rating should do it. .... but then I'm not sure where rating came from either....

I tried plain old $rating, didn't work

It's from GET:
$request = $_GET['request'];

I thought that maybe it wasn't adding because it can't add an int/string together, so you had to cast it to int. Or maybe that's just in C++

that's just C++.

hmm...I don't see how rating would work by itself. I thought you'd need to have $ infront of it to signify it's a variable. Does it give you any errors?

Try this:

$newrating = $row['rating'] + $rating;
echo "newrating = $newrating<br>"; //for testing
$newrating /= $numvotes;

Just to see if the last line isn't causing it. Debug it as much as possible, follow it through, and see where it gets you. That's about all I can suggest.

hahaha i am an idiot. it didnt work because i didnt put a $ in front of rating. Jeebus
