help with array and query

[gammaman]

I have a query that is using an array from a form on the previous page.  The array prints.  I used print_r and the values are getting passed.  However I try to use them in an update query and when the page loads, it loads as a blank page.

 

$Grade = ($_POST['grd']);

   print_r($Grade);


   $result=mysql_query("select CourseID,CourseName,Grade From Rcourse
                  WHERE StudentID='{$_SESSION['student']['user']}'");
    $cou=mysql_num_rows($result);
    
    while ($row=mysql_fetch_array($result))
    {
     
     $CourseID= $row['CourseID'];          
     $grade = $row['Grade'];
     $Course=$row['CourseName'];
     
     foreach ($Grade as $itm){
     mysql_query("Update Rcourse set Grade = '$itm'  where Grade < "A" AND StudentID='{$_SESSION['student']['user']}'");
     }
   }

mysql_query($sql) or die(mysql_error()) should become a habit.

 

otherwise, there is nothing in the posted code that is outputting anything to the browser, thus the blank page. unless you're not showing us all the code.

Not true because it should still print the array because I am using the print_r and now I do not see anything.
