Storing radio buttons in a session

[farril]

Hi there, im an infant when it comes to php, and only know a little. So please bare with me if my answers and explaining is slow.

 

Ive got a list of exam questions, each have four answers (selected by 4 radio buttons), this is held in mysql by ExamID, QuestionID, ExamAnswerA, ExamAnswerB, ExamAnswerC, ExamAnswerD.

 

all questions to a particular exam are listed using online.php?id=1 (where id = the examID)

 

ive split the exam questions up in to pages of 5 using this code

 

     			<?php   
                		if ($page > 1) 
			{    
				$prev = ($page - 1);
				echo "<a href=\"OnlineExam.php?id=$id&page=$prev\">Previous Page <span>|</span></a> ";	
			}

			for($i = 1; $i <= $total_pages; $i++) 
			{    
				if ($page == $i) 
				{        
					echo " $i <span>|</span> ";        
				}       
				else
				{          
					echo "<a href=\"OnlineExam.php?id=$id&page=$i\">$i <span>|</span></a> "; 
				}
			}
		if ($page < $total_pages) 
			{   
				$next = ($page + 1);
				echo "<a href=\"OnlineExam.php?id=$id&page=$next\"> Next Page</a>";
			}
                 
		?>

 

and this is my my answer choices..

 

<tr>
	<?php echo "<td class='title'><Input type = 'Radio' Name =".$getexamquestion3['QuestionID']. "value= 'A'></td>"
		?>
	<?php echo "<td><strong>A. </strong>".$getexamquestion3['ExamAnswerA']."</td>";
		?>
        </tr>

<tr>
	<?php echo "<td class='title'><Input type = 'Radio' Name =".$getexamquestion3['QuestionID']. "value= 'B'></td>"
		?>

	<?php echo "<td><strong>B. </strong>".$getexamquestion3['ExamAnswerB']."</td>";
		?>
</tr>

<tr>
	<?php echo "<td class='title'><Input type = 'Radio' Name =".$getexamquestion3['QuestionID']. "value= 'C'></td>"
		?>

	<?php echo "<td><strong>C. </strong>".$getexamquestion3['ExamAnswerC']."</td>";
		?>
</tr>

<tr>
	<?php echo "<td class='title'><Input type = 'Radio' Name =".$getexamquestion3['QuestionID']. "value= 'D'></td>"
		?>

	<?php echo "<td><strong>D. </strong>".$getexamquestion3['ExamAnswerD']."</td>";
		?>
</tr>

 

My question is, how do i use sessions to hold all the inputted answers in the radio buttons so i can go back and forth through the pages and not have to re input the data.

 

 

Sorry for the long explanation, i thought it would be needed.

 

Really hope you can help me with this.
