Creating Session and passing variables?

ackerley1 · #1 (**permalink**) 08-27-2004, 12:45 AM

I am trying to set up a multi page form using sessions (PHP) and it appears that I am missing something in my code.

I have the session_start(); function called and from what I have read that is essentially all I need- or so I gather from the books.

I want to send it without cookies (no lecture on security please) by adding it to the URL. I have about 20 variables to pass from each page. Do I need to declare/register these with the session? Do I need to name the session (session_name(); )?

Any help please?

Hi Rob
You need to register each session variable.
Below is a simple multi-part form using session varaibles.

I hope it is of help.

form1.php

Code:

<?
session_start();
session_register('s_fname','s_lname','s_house','s_street','s_city');
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html lang="en">
<head>
<title>Form Part 1</title>
</head>
<body>


Please Enter Your Name</p>
<form name="form1" method="post" action="form2.php">
  

 First Name 
    <input name="f_fname" type="text" id="f_fname">
  </p>
  

Last Name 
    <input name="f_lname" type="text" id="f_lname">
  </p>
  

 
    <input type="submit" name="Submit" value="Submit">
  </p>
</form>
</body>
</html>

form2.php

Code:

<?
session_start();
//with PHP register_globals off you MUST use
$_SESSION['s_fname']=$_POST['f_fname'];
$_SESSION['s_lname']=$_POST['f_lname'];

//with PHP register_globals on you can also use
//$s_fname=$f_fname;
//$s_lname=$f_lname;

?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html lang="en">
<head>
<title>Form Part 2</title>
</head>
<body>


Please Enter Your Address</p>
<form name="form2" method="post" action="form3.php">

    <input type="submit" name="Submit" value="Submit">

</form>


 </p>
</body>
</html>

form3.php

Code:

<?
session_start();
//with PHP register_globals off you MUST use
$_SESSION['s_house']=$_POST['f_house'];
$_SESSION['s_street']=$_POST['f_street'];
$_SESSION['s_city']=$_POST['f_city'];

//with PHP register_globals on you can also use
