Posting data from a form does not work. I have included a sample login form below that used to work on older versions of PHP. I add two echo statements (which you can see in the code below) for debugging purposes. I uncoment any of the ones that print the posting data and the script works. If I uncomment the ones that print the posted data it never reaches the "Here I am!" echo just before the redirect. It works fine if the user or password are not in the database but if the password and user are correct this is when it fails (i.e. it never gets to the echo statement "Here I am!"). 

Here is the script:

<?php
	// echo ("<p>User Name = $userName, Password = $password, op = $op</p>");
	$fontColor[0] = "color=black";
	$fontColor[1] = "color=black";

$login = "no";

if ($op == "ds")
{
	$login = "yes";

	// check each required field and create an error message.
	// if any of the required fields are blank, set $login to "no".

	if ($userName == "")
	{
		$err = "<p align=\"center\"><font color=red>There are errors!</font></p>";
		$login = "no";
		$fontColor[0] = "color=red";
	}

	if ($password == "") {

		$err = "<p align=\"center\"><font color=red>There are errors!</font></p>";
		$login = "no";
		$fontColor[1] = "color=red";
	}

    if ($login == "yes")
    {

		// echo ("<p>User Name = $userName, Password = $password, op = $op</p>");
		mysql_connect('localhost', 'userlogin', 'password') or die (mysql_error());
		mysql_select_db('database') or die (mysql_error());

		$result = mysql_query ("SELECT * FROM `users` WHERE User='$userName' AND Password=PASSWORD('$password')")
				or die (mysql_error());
		// echo ("<p>User Name = $userName, Password = $password, op = $op</p>");
		if ($row = mysql_fetch_object ($result))
		{
			$userID = $row->UserID;
			$fullName = $row->FullName;
			$userType = $row->Type;
			$email = $row->Email;

			session_start();
			session_register('userID');
			session_register('fullName');
			session_register('userType');
			session_register('userName');
			session_register('password');

			echo ("<p>Here I am!</p>");
			header("Location: http://www.fancc.org/nbosp/menu.php");
			exit;
		}
		else
		{

			$login = "no";
			$err = "<p align=\"center\"><font color=red>The User or Password is incorrect!</font></p>";
		}

    }
}

$form_block = "<form action=\"http://www.fancc.org/nbosp/login.php\" method=\"POST\">
    <p>
    <font size=\"2\" $fontColor[0]><strong>User</strong></font><br>
    <input type=\"text\" size=\"20\" name=\"userName\" value=\"$userName\"><br>
    <font size=\"2\" $fontColor[1]><strong>Password</strong></font><br>
    <input type=\"password\" size=\"20\" name=\"password\" value=\"$password\"></p>
    <p><input type=\"submit\" name=\"B1\" value=\"Login\"></p>
    <p>*If you have forgotten your password press here.</p>
    <input type=\"hidden\" name=\"op\" value=\"ds\">
</form>
";

Sorry, I ment when I comment out the echos that show the data posted it never reaches the "Here I am!" echo statement.

In PHP 4.2.0, the 'register_globals' setting default changed to
be off. See http://www.php.net/release_4_2_0.php for more info.
We are sorry about the inconvenience, but this change was a necessary
part of our efforts to make PHP scripting more secure and portable.

Just kidding.  Itchy trigger finger.

I checked the varialbles using phpinfo and it states that 'register_globals' is on.
