PHP Form error with session

I am so close to having this thing working.

Basically I have a form that submits to a checkout page where people would put in their info. I have a php that extends out a special array for a CRM API.

I did a print_r ($url); to see the results of an eror I am getting.

The name on the form is called email, inside the php I have it as $email = "email"; so it should choose the users input and send it to the API. However in the debug results I get an error message because it was trying to send: &email=email. I have at the top a session_start(); but I think I need to add more to the session just do not know the syntax.

 

okay had some success:

page one form name for email = email
 
page two (with php) : [B]$email = $_POST['email'];[/B]
[B]echo $email;[/B]
 
[code]
 
It does, but it refuses to allow anything else?
nextone is name (form name = fname)
 
[B]$fname = $_POST['fname'];[/B]
[B]echo $fname;[/B]

Code (markup):

results:

Notice: Undefined index: fname in ~/checkout.php on line 7[/code]

 

I don't understand what this has to do with sessions, as $email = $_POST['email']; is not a session.

Basically, if $email is empty, that's because $_POST['email'] is also empty.
The undefined index error is a notice, not an error. These can be ignored, however it is good practice to fix them.

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