passing $_POST['value'] through several pages

[HailDani]

Hello all you PHP programmers I'm pretty new to PHP, and loving it^^

anyways.. I am trying to pass the input value from page1.php to page2.php - That works. BUT, when I go to page3.php, PHP doesen't remember the input anymore..

I've tried sessions, but with no luck. The thing is, you have to be able to go back and write any other number (S/N) in the input field. So the function I'm going to use must NOT save the value so it can't be changed.

all help appreciated

Why did sessions not work? or could you just not get them to work, sessions were designed to fit the exact problem you are having

If you want to pass it to a third page, it'd be best to store the data in a Session or a Cookie.

For sessions, write session_start() at the top of every page, or turn automatic session on in your php.ini
then to write the data:
 $_SESSION['var1'] = "lol i like data!";
To Pull it
$data = $_SESSION['var1'];


If you REALLY want to continue using the post function, you'd have to create a Hidden field, and set the value
Ex:  <input type="hidden" name="mydata" value="lol data!" />
then as long as it's in the form, you can just do $mydata = $_POST['mydata'];
echo $_POST['mydata'] would return "lol data!"

you could try encrypted $_GET vars instead of $_POST vars.
*i've always had trouble with forwarding POST Vars, it may just be my host.*

here is ann example of how to encrypt ur get var...

$getVar = "Hi! I'm a HotNoob! ohhh hot Damn ";
$getVar_Enco = base64_encode($getVar); // there are other methods to encoding, but this is the easiest and simplest. i have made encryption protocols by hand before; it's not hard, but i don't want anyone to see them, for security reasons.

<a href='goto.php?data=<?php $getVar_Enco?>'>

Then to decode it,
$getVar_Enco = $_GET['data'];
$getVar_Deco = base64_decode($getVar_Enco);

For the most part, base64 encoded data is compatible with sending by get vars, i have had no real problems with it so far.

hope i helped

Sessions is the way to go to keep persistent. You can use POST and hidden input in a form but you need to use JS to trigger it on leaving the page which is not as reliable as a session.
