I have created a "grading table" that declared my low marks, high marks, grade and comment. I also have my result table with the following column label 'id','subjectid','studentid','grades', 'comments'; to store the input results. My problem now is to create the php code to store what ever score that is entered and compare it with the assigned grades in the database. Below is my code
{
$marks=array();
$class=$_POST['class'];
$studentid=$_POST['studentid'];
$mark=$_POST['marks'];
$grades=$_POST['grades'];
$comments=$_POST['comments'];
//coding
$sum=$mark*10; //total marks
$avg=$sum;
if($avg>=0&&$avg<=50)
$grades="Fail";
if($avg>50&&$avg<=70)
$grades="C";
if($avg>70&&$avg<=80)
$grades="B";
if($avg>80&&$avg<=90)
$grades="A";
if($avg>90)
$grade="E";
//end
$stmt = $dbh->prepare("SELECT tblsubjects.SubjectName,tblsubjects.id FROM tblsubjectcombination join tblsubjects on tblsubjects.id=tblsubjectcombination.SubjectId WHERE tblsubjectcombination.ClassId=:cid order by tblsubjects.SubjectName");
$stmt2=$dbh->prepare("SELECT id,StudentId,ClassId,SubjectId,marks,grades,comments from tblresult join grading on marks between lowmark and himark");
$stmt->execute(array(':cid' => $class));
$sid1=array();
while($row=$stmt->fetch(PDO::FETCH_ASSOC))
{
array_push($sid1,$row['id']);
}
for($i=0;$i<count($mark);$i++){
$mar=$mark[$i];
$sid=$sid1[$i];
//my code
//$totalmarks=$marks*10;
$sql="INSERT INTO result(StudentId,ClassId,SubjectId,marks,grades,comments) VALUES(:studentid,:class,:sid,:marks,:grades,:comments)";
$query = $dbh->prepare($sql);
$query->bindParam(':studentid',$studentid,PDO::PARAM_STR);
$query->bindParam(':class',$class,PDO::PARAM_STR);
$query->bindParam(':sid',$sid,PDO::PARAM_STR);
$query->bindParam(':marks',$mar,PDO::PARAM_STR);
$query->bindParam(':grades',$grades,PDO::PARAM_STR);
$query->bindParam(':comments',$comments,PDO::PARAM_STR);
$query->execute();
$lastInsertId = $dbh->lastInsertId();
if($lastInsertId)
{
$msg="Result added successfully";
}
else
{
$error="Please correct the error";
}
}
}
?>
