Because the value of $file isn't saved between submits. Every submit
does the same thing: concatenate $_POST['field'] to an uninitialized
variable $file which defaults to the empty string.

You echo the contents into the form, but not as a form variable.

<input type=\"text\" name=\"field\">
You haven't loaded this field with the previous contents (no 'value'
attribute), so it's empty each time.

Try this instead:

<html>
<head>
<title>Good Idea!</title>
</head>
<body>
<?php
error_reporting (E_ALL);
ini_set('displa y_errors', '1');

session_start() ;
if (!isset($_SESSI ON['file'])) $_SESSION['file'] = '';

$_SESSION['file'] .= $_POST['field'] . '<br/>';

echo "
<form action=\"$_SERV ER[PHP_SELF]\" method=\"post\" >
<input type=\"text\" name=\"field\">
<input type=\"submit\" value=\"Submit\ ">
";

echo $_SESSION['file'];
?>
</body>
</html>

But when I try this I submit a new string each time..
Only the last submitted string is printed..

Looks like I missed something I thought obvious, you're right. Try this.

<html>
<head>
<title>Silly idea?</title>
</head>
<?
$file = $_POST['text'].$_POST['field'];
echo "
<form action=\"$_SERV ER[PHP_SELF]\" method=\"post\" >
<input type=\"text\" name=\"field\">
<input type=\"hidden\" name=\"text\" value=\"$file\" >
<input type=\"submit\" value=\"Submit\ ">";
echo $file;
?>

Well, it works, but it's not scalable. If it gets any more complicated,
database it.

Glad to help though.
