You are probably using a book that assumes that the register_globals option is enabled. This was the default up until about 3 years ago when it was found that enabling register_globals can cause security problems. The default was changed to disabled and now to get the values from forms and URLs, you need to reference the appropriate superglobal array: $_POST for forms using the method="post" and $_GET for forms using method="get" and for variables on the URL. See http://www.php.net/register_globals

In your case you need to use:
[code]
<?php
echo $_POST['name'];
?>
[/code]

i tried the $_post and still cant figure it out..  still getting a blank page when it goes to the php page.  this is what i have in the .php page as of now.

[code]
<html>
<head>
<title>Untitled Document</title>
</head>

<body>
<?
echo $_POST['name'];
?>
</body>
</html>
[/code]

i even tried to set the post name to a var. and then echoing it and still nothing is output to the browser.

Yes, but then he would see the code and not just a blank page.

Change your test2.php page to:

[code]
<?PHP
echo 'Name: ', isSet($_POST['name']) ? $_POST['name'] : 'Not set' ;

?>
[/code]

Make sure the test2.php is in the same directory as your html form.

Create this in a separate file and run it to see what your php settings are and it will tell you if your server and PHP are setup right:

[code]
<?PHP
phpinfo();
?>
[/code]

Maybe its echoing nothing because your host doesnt support php?

Read his/her post again carefully. You'll notice that it's a local installation.

D'oh, :P
Maybe there were problems with his download or something? Or like kenrbnsn said, it could be that the server doesn't allow short style tags.
