Question

I’m using this php code to update a table, but nothing is updating?

if(isset($Submit))
{
    include('connect_mysql.php');
    for($i=0;$i<$count;$i++)
    {
        $sql = "UPDATE $table SET cost='{$cost[$i]}', net=('{$bypiece[$i]}' + '{$cost[$i]}') WHERE serial='{$serial[$i]}'";
        $result = mysql_query($dbcon, $sql);
    }
}

if($result)
{
    header("location:admin-index.php#office.php");
    mysql_close();
}

It seems like it should work, and i have no reason why it wouldn’t.
My variables are defined, and when i echo them out with an else statement everything seems to be alright. Yet the data isn’t being updated, and the header isn’t redirecting.
Can anyone help me find a working solution?

A good idea when debugging is turn on error reporting.

error_reporting(E_ALL);
ini_set('display_errors', '1');

Also see if you have any errors in your sql statement by changing

$result=mysql_query($dbcon, $sql);

to

$result=mysql_query($dbcon, $sql) or die(mysql_error());
