issues with form

[gammaman]

Ok what this code does is check to see what courses a student is registered in and displays them in a table.  If they have a grade for the course it is also displayed.  If not I have an input box next to the course so that a grade could be entered.  Problem is when I click submit, instead of going to the page from the "action" on the form, it just reloads the current page and all I see is one table row instead of seeing the number of rows for which the student has courses.  I think it may be because I am trying to submit multiple values using the same input name.  If it is possible to send the information using the same input name, but stored in an array, that might clear things up.  What do you think.

 

<?php

  $conn=mysql_connect("localhost","fierm","13183");

  if(!$conn){
    echo "failed";
}else{

   mysql_select_db(fierm);

   $StudentID = $_POST['id'];

   session_start();
   $_SESSION['admin']['admins'];

   $_SESSION['admin']['adminpass'];
   
   echo "<form action = '' type = 'hidden' method='post'>";
   
   echo '<table border="1">';
   echo "<tr><th>CourseID</th><th>CourseName</th><th>Grade</th></tr>"; 

   $result=mysql_query("select CourseID,CourseName,Grade From Rcourse
                  WHERE StudentID='$StudentID'");

   $cou=mysql_num_rows($result);
   


   if ($cou==0){
      echo "Not in Any Courses";
   }else{
   
   
   while ($row=mysql_fetch_array($result))
   {

     $CourseID= $row['CourseID'];          
     $grade = $row['Grade'];
     $Course=$row['CourseName'];
   
         
     if (($grade) < "A"){
     $value =  "<form action='updateGrades.php'  method= 'post'>
                 <input name = 'grd' size='5' type='text' />";
                
             
     	     }else{ 
          	$value = "$grade";
           
     } #end if...else
       echo "<tr><td>$CourseID</td><td>$Course</td><td>$value</td></tr>";
       
       
   } #end while
   
    // "</form>";
   } #if...else
     
   echo "</table>";
     echo '<input name="submit" type="submit" value="submit" />';
   echo "</form>";   
   echo "<b>Return to Student Page</b>";
   echo "<a href = \"student.php\">Return to Student Page</a>";

   


}
?>

If it is possible to send the information using the same input name, but stored in an array, that might clear things up.  What do you think.

 

Yes, change name='grd' to name='grd[]' and your input values will be in an array named grd

there is no action defined here, which is why it goes to itself:

 

echo "<form action = '' type = 'hidden' method='post'>";

Yeah I realize that, I took it out, I thought at one point I would need a hidden form on this page but I don't.  I just need away to store all of the inputs using the same input name so that the next page can retrieve all of the values.

Yes, change name='grd' to name='grd[]' and your input values will be in an array named grd

 

How do I retrieve them on the next page because I tried to ways and neither work.

 

I tried  $var=$_POST['grd[]'];

and      $var=$_POST['grd'];
