[SOLVED] Session Question?

[Solarpitch]

Hey,

 

I'm currently using this code to assign form details to session variables, then on the second piece of code I am trying to echo the value of the session variables but noting will print to screen. Here's an example of what I am trying..

 

// Get details from form and assign to session - then move to step 2

 

<?php

session_start();

$process = isset($_POST['process']) ? $_POST['process'] : '';

if ($process != "execute")
{
//not being submitted...
}
else
{	

$firstname = $_POST['firstname'];
$_SESSION['firstname'] = $firstname;

$lastname = $_POST['lastname'];
$_SESSION['lastname'] = $lastname;

$email = $_POST['email'];
$_SESSION['email'] = $email;


header("Location:step2.php");

?>

}

 

 

 

// This is the code on the other page where I am trying to display the session values...

 

<?php

session_start();

echo $_SESSION['firstname'];
echo $_SESSION['lastname'];
echo $_SESSION['email'];

?>

Is the bottom code step2.php?

i believe if your error reporting is on you should get a warning message saying header already sent etc...

 

your session start should be at the top most of the page right after the declaration of php

Judging from the appearance of the posted code, you have multiple newlines at the start of each file before the first <?php tag. These are content that are output to the browser and prevent the session from starting, on both pages.

 

New lines after the <?php tag are not content and are not output to the browser, unless specifically echoed using php code.

There are 5 steps pages, each with different forms that gather different user info. I am storing all user details from the forms into a session, then on Step5.php I want to display all of the session details so the user can confirm the form.

 

Here's the form from Step1.php

 

teng84 - I tried that but still no joy

 

<form name="form1" method="post" action="step1.php">
                      <table width="563" border="0" cellspacing="2" cellpadding="0">
                        <tr>
                          <td> </td>
                          <td width="419"> </td>

Thats only in the above example but this isnt the case on my page itself.

[redarrow]

try that if it works then it a header problam / whight spaces.........

 

<?php
ob_start();
session_start();
$process = isset($_POST['process']) ? $_POST['process'] : '';
if ($process != "execute"){
}else{	
$firstname = $_POST['firstname'];
$_SESSION['firstname'] = $firstname;
$lastname = $_POST['lastname'];
$_SESSION['lastname'] = $lastname;
$email = $_POST['email'];
$_SESSION['email'] = $email;
header("Location:step2.php");
ob_flush();
}
?>

 

 

<?php
ob_start();
session_start();
echo $_SESSION['firstname'];
echo $_SESSION['lastname'];
echo $_SESSION['email'];
ob_flush();
?>

[Solarpitch]

Thats still doesnt work I am afraid. Would I need to include ob_start() on the page that I am calling the session to display also.

 

(I am offline after this post, but I'll check back later.. thanks for the help guys)

[redarrow]

you need to try the format as posted on all pages with no whight gaps and try ob_start() and ob_flush().....

[Ken2k7]

Shouldn't it be $_POST['submit'] and not $_POST['process'] ?

[redarrow]

no but

 

if($_POST['submit']){

 

}

 

might do it.........

[teng84]

the other form is set as hidden so if submit is set process will also be set  right?

[redarrow]

looks good to me but why did he have it not there no need for the ternary op || or good enough?

<?php
ob_start();
session_start();
$process =(isset($_POST['submit']) || $_POST['process'] ) ;
if ($process != "execute"){
}else{	
$firstname = $_POST['firstname'];
$_SESSION['firstname'] = $firstname;
$lastname = $_POST['lastname'];
$_SESSION['lastname'] = $lastname;
$email = $_POST['email'];
$_SESSION['email'] = $email;
header("Location:step2.php");
ob_flush();
}
?>

Please check your web server log for the errors that are preventing the session from working. Until you know why they are failing, adding and changing code is pointless.

[Solarpitch]

Hey guys,

 

Just to let you know.. the session seemed to work when I used isset to check if the variable was set, then if it was assign the value to the session - and this works fine...

 

$firstname = $_POST['firstname'];

if(isset($firstname))

{$_SESSION['firstname'] = $firstname;}
