saving $_POST variables

[acidglitter]

on one of my pages it checks if there is a $_POST variable and a session variable set. if the session variable isn't set then the page automatically refreshes by going to the same url again (but then it loses the $_POST variable). how can i also keep the $_POST variable doing that? isn't there a way to send it?

Save it into the $_SESSION array.

okay but now for some reason its not getting the saved sessions. whats happening is someone is buying something, then coming back to the site from paypal. on the first time they come back, their member id (saved as a session) is missing. so the page refreshes to get the member id. i tried using header("Location: page") and i just barely tried with html like <meta http-equiv="refresh" content="0;url=page"> but neither will work. what would solve basically everything would be if i could just get the member id saved without having to refresh the page first.

how are you storing the session id? in the url or in a cookie?

[acidglitter]

do you mean the member id? at the top of the page i just have session_start()

Why is their member ID missing?  How are you saving it/accessing it?

 

Also, for your information, you can't redirect POST data like that.  You can make another POST request to the next page with cURL, but that's completely different than what you're trying to do.

i'm saving it in a session. normally to get it you would go $_SESSION['member_id']. but because you leave the site to go to paypal, that session kind of temporarily ends, then when you come back you need to refresh the page to get it back again..

[DarkWater]

That makes no sense.  The session does not temporarily end.

i don't know if thats what it ActuallY does, but you do leave the site and the session isn't being used while you're gone

You need to make sure you are coming back to the same domain that the session was set on, ie www.mysite.com or mysite.com.  The session will remain until the browser is closed or times out (24 mins by default).

its coming back to httpS://mysite.com does that make a difference?

[DarkWater]

Yes, it does.

 

EDIT: I think.

Dear

 

 

      Just put or assign the varibles in the new session array and encrypte it and decrypt it

      play with it.

<?php
// Keep this at the top of ur pages
session_start();
?>

 

<?php
// Create the form
echo "<form action=\"\" method=\"post\"><input name=\"fieldname\" type=\"text\" size=\"8\" maxlength=\"12\" /></form>";
?>

 

<?php
// Call the forms variables and store them into a session array
$fieldvar = $_POST['fieldname'];
$_SESSION['fieldname'] = $fieldvar;
?>

 

<?php
// Call the session back to the document
$fieldname = $_SESSION['fieldname'];
echo "The field is " . $fieldname;
?>
