[SOLVED] Session Help - Passing Variables Between Pages

[skot]

Hi All,

 

I'm trying to use a multi-page form to collect form entered data and email this to myself. I have tried multiple methods of doing this and using sessions seems to be the answer.

 

The issue is that no variables are actually passed over, thus not a lot is emailed.

 

URL: http://www.centurysoftware.co.uk/demonstrations.html

 

I am using cs_bookdemo.php to collect name, numbers and addresses. This form posts to cs_bookdemo2.php, which contains the following code:-

 

<?php
session_start();
$_SESSION['name']=!empty($_POST['name'])? htmlspecialchars($_POST['name']) : null;
$_SESSION['company']=!empty($_POST['company'])? htmlspecialchars($_POST['company']) : null;
$_SESSION['sector']=!empty($_POST['sector'])? htmlspecialchars($_POST['sector']) : null;
$_SESSION['tel']=!empty($_POST['tel'])? htmlspecialchars($_POST['tel']) : null;
$_SESSION['mob']=!empty($_POST['mob'])? htmlspecialchars($_POST['mob']) : null;
$_SESSION['emai']=!empty($_POST['email'])? htmlspecialchars($_POST['email']) : null;
$_SESSION['a1']=!empty($_POST['a1'])? htmlspecialchars($_POST['a1']) : null;
$_SESSION['a2']=!empty($_POST['a2'])? htmlspecialchars($_POST['a2']) : null;
$_SESSION['a3']=!empty($_POST['a3'])? htmlspecialchars($_POST['a3']) : null;
$_SESSION['a4']=!empty($_POST['a4'])? htmlspecialchars($_POST['a4']) : null;
$_SESSION['a5']=!empty($_POST['a5'])? htmlspecialchars($_POST['a5']) : null;
?>

 

cs_bookdemo2.php collects more information and posts to cs_bookdemo3.php, which has the same session code and variables with the addition of the fields just posted on page 2:

 

<?php
session_start();
$_SESSION['name']=!empty($_POST['name'])? htmlspecialchars($_POST['name']) : null;
$_SESSION['company']=!empty($_POST['company'])? htmlspecialchars($_POST['company']) : null;
$_SESSION['sector']=!empty($_POST['sector'])? htmlspecialchars($_POST['sector']) : null;
$_SESSION['tel']=!empty($_POST['tel'])? htmlspecialchars($_POST['tel']) : null;
$_SESSION['mob']=!empty($_POST['mob'])? htmlspecialchars($_POST['mob']) : null;
$_SESSION['emai']=!empty($_POST['email'])? htmlspecialchars($_POST['email']) : null;
$_SESSION['a1']=!empty($_POST['a1'])? htmlspecialchars($_POST['a1']) : null;
$_SESSION['a2']=!empty($_POST['a2'])? htmlspecialchars($_POST['a2']) : null;
$_SESSION['a3']=!empty($_POST['a3'])? htmlspecialchars($_POST['a3']) : null;
$_SESSION['a4']=!empty($_POST['a4'])? htmlspecialchars($_POST['a4']) : null;
$_SESSION['a5']=!empty($_POST['a5'])? htmlspecialchars($_POST['a5']) : null;
$_SESSION['p1']=!empty($_POST['p1'])? htmlspecialchars($_POST['p1']) : null;
$_SESSION['p2']=!empty($_POST['p2'])? htmlspecialchars($_POST['p2']) : null;
$_SESSION['p3']=!empty($_POST['p3'])? htmlspecialchars($_POST['p3']) : null;
$_SESSION['reqdate']=!empty($_POST['reqdate'])? htmlspecialchars($_POST['reqdate']) : null;
$_SESSION['time']=!empty($_POST['time'])? htmlspecialchars($_POST['time']) : null;
?>

 

Page 3 then collects more information and posts to cs_bookdemo4.php, which contains the email code:

 

<?php

session_start();
$_SESSION['name']=!empty($_POST['name'])? htmlspecialchars($_POST['name']) : null;
$_SESSION['company']=!empty($_POST['company'])? htmlspecialchars($_POST['company']) : null;
$_SESSION['sector']=!empty($_POST['sector'])? htmlspecialchars($_POST['sector']) : null;
$_SESSION['tel']=!empty($_POST['tel'])? htmlspecialchars($_POST['tel']) : null;
$_SESSION['mob']=!empty($_POST['mob'])? htmlspecialchars($_POST['mob']) : null;
$_SESSION['emai']=!empty($_POST['email'])? htmlspecialchars($_POST['email']) : null;
$_SESSION['a1']=!empty($_POST['a1'])? htmlspecialchars($_POST['a1']) : null;
$_SESSION['a2']=!empty($_POST['a2'])? htmlspecialchars($_POST['a2']) : null;
$_SESSION['a3']=!empty($_POST['a3'])? htmlspecialchars($_POST['a3']) : null;
$_SESSION['a4']=!empty($_POST['a4'])? htmlspecialchars($_POST['a4']) : null;
$_SESSION['a5']=!empty($_POST['a5'])? htmlspecialchars($_POST['a5']) : null;
$_SESSION['p1']=!empty($_POST['p1'])? htmlspecialchars($_POST['p1']) : null;
$_SESSION['p2']=!empty($_POST['p2'])? htmlspecialchars($_POST['p2']) : null;
$_SESSION['p3']=!empty($_POST['p3'])? htmlspecialchars($_POST['p3']) : null;
$_SESSION['reqdate']=!empty($_POST['reqdate'])? htmlspecialchars($_POST['reqdate']) : null;
$_SESSION['time']=!empty($_POST['time'])? htmlspecialchars($_POST['time']) : null;
$_SESSION['location']=!empty($_POST['location'])? htmlspecialchars($_POST['location']) : null;
$_SESSION['source']=!empty($_POST['source'])? htmlspecialchars($_POST['source']) : null;
$_SESSION['notes']=!empty($_POST['notes'])? htmlspecialchars($_POST['notes']) : null;

mail('myemail@address.co.uk','** New Product Demo Request ($reqdate) (Time: $time) **',"A website visitor has submitted the following demonstration request:-\n\n

?>

 

The resulting email output is everything above but excludes any data entered by the user.

 

What am I doing wrong?

 

I have also tried using hidden fields and populating these fields with php, and getting that particular page to "pass on" the variables again to the next page but I'm having no luck.

 

Any guidance would be appreciated.

 

Thanks in advance.

you are doing 2 things wrong.....

 

1) On cs_bookdemo3.php (nd subsequent pages) you have something like this:

$_SESSION['name']=!empty($_POST['name'])? htmlspecialchars($_POST['name']) : null;

But there shouldn't be a form element of 'name', since that was on cs_bookdemo.php and was posted to cs_bookdemo2.php. So, when you get to this step, it will take whatever cs_bookdemo2.php set and overwrite it with null.

 

2) You have the values stored in $_SESSION, but you are trying to access them with directly. Example:

$_SESSION['reqdate']=!empty($_POST['reqdate'])? htmlspecialchars($_POST['reqdate']) : null;
....
Requested Date: $reqdate \n

You need to use the session variable to read it:

Requested Date: {$_SESSION['reqdate']} \n

Hi Rhodesa. Thanks for your help. I have removed 'null' from the code but I receive a php error.

 

The code is now:

 

<?php

session_start();

$_SESSION['name']=!empty($_POST['name'])? htmlspecialchars($_POST['name']);

$_SESSION['company']=!empty($_POST['company'])? htmlspecialchars($_POST['company']);

$_SESSION['sector']=!empty($_POST['sector'])? htmlspecialchars($_POST['sector']);

$_SESSION['tel']=!empty($_POST['tel'])? htmlspecialchars($_POST['tel']);

$_SESSION['mob']=!empty($_POST['mob'])? htmlspecialchars($_POST['mob']);

$_SESSION['email']=!empty($_POST['email'])? htmlspecialchars($_POST['email']);

$_SESSION['a1']=!empty($_POST['a1'])? htmlspecialchars($_POST['a1']);

$_SESSION['a2']=!empty($_POST['a2'])? htmlspecialchars($_POST['a2']);

$_SESSION['a3']=!empty($_POST['a3'])? htmlspecialchars($_POST['a3']);

$_SESSION['a4']=!empty($_POST['a4'])? htmlspecialchars($_POST['a4']);

$_SESSION['a5']=!empty($_POST['a5'])? htmlspecialchars($_POST['a5']);

?>

 

But when I go to page 2 I get this error:-

 

Parse error: syntax error, unexpected T_VARIABLE in /home/bridgey/public_html/cs_bookdemo2.php on line 4

You want to use:

if(!empty($_POST['name'])) $_SESSION['name'] = htmlspecialchars($_POST['name']);

Works perfect

 

You're amazing

 

Thank you
