[Resolved] Passing session data across pages

endlyss

Trying to get form input passed across multiple pages and write it all to file at the end.

Getting all confused from all the books and documentation I've waded through.

Super simple script to use as template. Three pages...

Page one...

first form

First Name
<br>
<input type="text" name="f_name" size="25">
<br>

Last Name
<br>
<input type="text" name="l_name" size="25">
<br>

</form>

Page 2...

data.php

<?php

session_start();

$f_name=$POST['f_name'];
$l_name=$POST['l_name']; // Probably don't need these lines?

$session['f_name'] = $post['f_name'];
$session['l_name'] = $post['l_name'];

echo $f_name;
echo session_id();

$fp = fopen("test.txt", "w");

session_encode(); /???

echo "
<html>
<head>
<title>Untitled</title>
</head>

</body>
</html>";

?>

Page 3...

data2.php

<?php

session_start();

$session['test'] = $post['test'];
$session['f_name'] = $post['f_name'];
$session['l_name'] = $post['l_name'];

echo session_id();
echo $f_name;

$fp = fopen("test", "w");
session_encode();
fputs($fp, session_encode()); // following example from book

fclose($fp);

As you can see this is a train wreck and I am lost.

I want to write $f_name, $l_name, and $test to text file (and format it to a certain extent).

Thanks for helping me clear this up.

the basic idea:

<?php
session_start();

if (!isset($_POST['submit']))
{
	echo '
	<form action="" method="POST">
	First Name : <input type="text" name="f_name" size="25"><br>
	Last Name: <input type="text" name="l_name" size="25"><br>
	<input type="submit" name="submit" value="go to step 2">
	</form>
	';
}

if (isset($_POST['submit']) && $_POST['submit'] == 'go to step 2')
{
	$_SESSION = $_POST;

echo '
<form action="" method="POST">
text: <input type="text" name="text" size="20"><br>
<input type="submit" name="submit" value="go to step 3">
</form>
';
}

if (isset($_POST['submit']) && $_POST['submit'] == 'go to step 3')
{
	$string = $_SESSION['f_name'] . "\r\n" . $_SESSION['l_name'] . "\r\n" . $_POST['text'];
	$handle = fopen('test.txt', 'w');
	$fwrite = fwrite($handle, $string);
	echo $fwrite . ' bytes written to test.txt';
}
?>

Hi!

Well, i've looked at your code a bit and i myself don't use much flat file based session stuff.

Anyway, why not try registering the variables you want to keep alive during the transition of pages?

So from the first file, you post the variables to data.php, so in data.php, you could do:

session_register('f_name');
$f_name=$f_name;
session_register('l_name');
$l_name=$l_name;

So then those 2 variables are registered with the session, meaning you don't have to worry about them losing their value through the session.

In data.php you have a new form which posts another value to the next one, data2.php.

if you do the same thing, like:

session_register('test');
$test=$test;

Then all 3 are registered and could be written to a file as in:

$fp = fopen("test","w");
fputs($fp, $f_name);
fputs(......;
fclose($fp);

That should do it, though you might like to add some cr/lf.

Once written, you can unset the variables by using session_unregister($l_name);

Don't forget to clear them by using unset() afterwards, session_unregister() only keeps them from the session, but they maintain their value.

Hope this helped a bit.

with regard to thefisherman's post: use of session_register() and session_unregister() is now deprciated.

thefisherman

Yes, they are..

with register_globals disabled, session_(un)register won't work.

It has and still does work fine for me, so i guess sometimes it's a matter of choice.
