After Form Submits, it goes back to the same page

I attached the code, I have looked at it for a long time and can't find anything wrong with it. The data gets submitted the database successfully.

Thanks

FYI: I used CSS Form Builder to create the form and DataAssist Insert Single Record.

Thanks again

the following code is preventing the header() function from redirecting the page:
echo "Starting to output current session data";
print_r($HTTP_SESSION_VARS);



if you where to add this code at line 1 to turn error reporting on:

<?php 

error_reporting(E_ALL);

ini_set('display_errors','on');

?>

you would see that there is Headers Already Sent error occurring.

the headers already sent error occurs if there is any output to the page before the session-start() or header() functions are called. you code:
the following code is preventing the header() function from redirecting the page:

echo "Starting to output current session data";
print_r($HTTP_SESSION_VARS);



is causing the output to the page, which is preventing the header() function from executing.

Thanks for the quick reply. I removed ..

<?php

// this starts the session
session_start();

// echo variable from the session, we set this on our other page
echo "Starting to output current session data";
print_r($HTTP_SESSION_VARS);

?>

and put in the error output message you showed me. When they page loads, I still get a header error (image attached). When I submit, I sent the second error (image attached).

Sorry, I'm new to php... I guess I was trying to session_start() twice on one page. It's still doing the same thing.

Thanks

header("Location: ".$WA_redirectURL);

see the following page for information on the headers already sent error:
148/

Thank you! It was 1 whitespace after a "?>" !!!!
