I’m new to PHP so it might sound stupid.

I’m trying to update the database, this is my code so far. 

$pulldown = CleanUserInput($_GET['q']);
$name = CleanUserInput($_POST['name']);

$result = mysql_query("UPDATE Suppliers SET SuppName = ('$name') 
WHERE SuppName = ('$pulldown')");

How do I use $_GET to set the column that it will update?

    Assuming that your variables are being passed correctly to this script, the 3rd line of your script should look like this:

    $result = mysql_query("UPDATE Suppliers SET SuppName = '".$name."' WHERE SuppName = '".$pulldown."';") or die(mysql_error());

    To set the column name that is to be update via a $_GET variable, your code could look like this:

    $pulldown = CleanUserInput($_GET['q']);
$name = CleanUserInput($_POST['name']);
$column_name = CleanUserInput($_GET['column_name']);
$result = mysql_query("UPDATE Suppliers SET `".$column_name."` = '".$name."' WHERE `".$column_name."` = '".$pulldown."';") or die(mysql_error());

    Of course this will the replace the value in the column for the variable $column_name. Not sure if that is what you are trying to do.
