Session Troubles

FireAndIce

Hi all!

I'm pretty new to PHP but have been tasked to design an online survey. However, the survey consists of close to 100 questions, so I'm breaking them up into bite-sized pages with about 10 questions per page.

What I need to do is to pass the information from one page to another but I cannot seem to grasp the syntax for the sessions.

Would really appreciate it if someone could correct my syntax or give me a suggestion on a better way to do this.

This is what I have

<?php
	session_start();
?>
<html>
<head><title>Testing Sessions Page 1</title></head>
<body>
<?php
	$_SESSION['session_var']="$radiobutton";

?>
<form name="form1" method="post" action="">
  <table width="750" border="0">
    <tr>
      <td><font size="-1" face="Arial, Helvetica, sans-serif">1. We have a system 
        to measure customer satisfaction.</font></td>
      <td width="25"><input type="radio" name="radiobutton" value="1"></td>
      <td width="25"><input type="radio" name="radiobutton" value="2"></td>
      <td width="25"><input type="radio" name="radiobutton" value="3"></td>
      <td width="25"><input type="radio" name="radiobutton" value="4"></td>
      <td width="25"><input type="radio" name="radiobutton" value="5"></td>
      <td width="25"><input type="radio" name="radiobutton" value="6"></td>
    </tr>

</table>
</form>
</body></html>

you need to store the answers in an array within the $_SESSION array. a simple example:

<?php
session_start();

if (!isset($_POST['submit']))
{
	echo '
	<form action="" method="POST">
	question #1:<br>
	<input type="radio" name="answer[1]" value="1">1<br>
	<input type="radio" name="answer[1]" value="2">2<br>
	<input type="radio" name="answer[1]" value="3">3<br>
	<input type="radio" name="answer[1]" value="4">5<br>
	<input type="radio" name="answer[1]" value="5">5<br>
	<input type="submit" name="submit" value="submit">
	</form>
	';
}
else
{
	$_SESSION[1] = $_POST['answer'][1];
	print_r($_SESSION);
}
?>

devinemke,

Thanks for your reply!

Could you please explain what this part does?

if (!isset($_POST['submit']))

Cos I can't figure it out.

Am I correct to say that the [1] in the $_SESSION[1] is the name of the array and the answer[1] in name="answer[1]" is the name of the radio group?

In case you can't tell already, I'm really new to PHP.

Thanks!

answer[1] is the array of answers for question #1 (the next group of answers will be answer[2], answer[3] etc...)

$SESSION[1] is where the answer to question #1 is stored. you would then add $SESSION[2] , $_SESSION[3] etc... for the rest of the questions.
