Hello.
I've been viewing this site for a long time, but finally decided to join and ask for help. I'm using citrusDB and a sample code from authorize.net and I want to pass off some information from the citrus DB to the authorize.net code. I've been trying to do this with sessions all night and can't seem to get it. If it means anything, I set up two PHP files one that sets a session variable, and the second that displays it, and that is working fine so I'm not convinced it's a configuration issue.

Here's the code on the citrus file:

        echo '</table>';
        echo "<p><a href=\"$payment_url\">$l_paybillonline</a>";
$ccproc = $total_due;
echo $ccproc;
$_SESSION['ccproc'] = $ccproc;
echo $_SESSION['ccproc'];

                break;

What i tried to do here was set the session variable "ccproc" then display t, and it DOES dislay properly.

Then on the second page:

echo $_SESSION['ccproc'];

and it does not display the same number. As a test, I am using "100.00", so for the first one, it displays "100.00" where I echo both $ccproc, and the session variable.

My error log is saying undefined index on the second page, but when I did this in a test environment with just a simple variable, it was coded exactly the same way, but it worked fine. Any thoughts?

This is the code from the file that displays the information. It's basically giving me a total dollar amount that the customer owes, and when they click the pay bill online link, I want it to pull the amount owed and send it to the next php document which processes the credit card. Almost all the way at the bottom is where my variables are struggling. I set ccproc to the same amount that total_due was, and then echo'd it to verify that it took, which it does.

My thoughts were if I can at least get the session variable to display on this page, I can use the information to process the card. WHen I call it, it just appears blank, and when I look at the error log on the server, it shows undefined index on the second page of code.

Try adding ob_start() before headers and ob_end_flush() to end. Do this for both pages. ob = output buffer.

Use session_start on top of page.
There should be no other HTML codes, html comments or any white space.

I tried the ob code and still no dice. I can provide a link to the test server I'm using if anyone would like to see the code for the rest of the design. Would there be a setting elsewhere in the php file disabling session variables?

what php editor you are using?Is it has error highlighting on? If so check if you have any errors in your pages after that you can start your session in the connection file and use require once or closures in all your code with the connection file and use session_start(); in al you pages like this

<?php 
require_once('conection.php');
session_start();


?>

I'm usng Notepad++. We decided to go a different route to process the payment and it seems to be working. Thanks for all of the help!
