sessions and forms

[tim0]

I've pulled this script off a tutorial I've been trying to follow about e commerce. It was written before register globals were turned off, and so I've been trying to update it to get it to run.

Is it possible to tell me why the above code won't printout the username to the page after the form has been submitted? Am I just going to have to write the extra assignment $SESSION = $POST instead?

<?

session_start();

$frm = $_SESSION;

?>

<form name="entryform" method="post" action="<?=$PHP_SELF ?>">
<table border=1>
<tr>
	<td class=label>Username:</td>
	<td><input type="text" name="username" size=25 value="<? $frm["username"] ?>">
		</td>
</tr>
<tr>
	<td></td>
	<td><input type="submit" value="Signup"></td>
</tr>
</table>
</form>

<?
echo $frm["username"];

?>

Are you willing to try this at your own?

Yes, I've entered the extra code as below. It works fine, but I'm trying to understand why the writer of the tutorial got away without using $_POST, and relyed only on sessions to submit this form data?

This is the updated section:

<? 

session_start(); 

$_SESSION = $_POST;

$frm = $_SESSION; 

?>
