    Cannot read information from form using POST or GET ($_Post is empty)

    I am having problems in my php code. I am relatively new to php but I
    know some basics.

    This is the problem:

    when i try to echo some information that is typed into form back to
    the screen i get absolutely nothing. It seems like $_POST['name'] is
    an empty string, along with $_POST and $_GET['name'].

    I looked around to see if someone else had the same problem and found
    that some people's code didn't work because of IE6. but i also tried
    mine on Netscape and i got the same problem.

    So why is $_POST empty after posting information. Even $_GET was
    empty.

    any help is appreciated.


    all of those returned empty

    echo $_POST;
    echo $_POST['name'];
    echo $_GET['name'];



    here is the code:
    the code was originially meant to send an email but i commented the if
    statement out to see why it wasn't working

    <html>
    <head><title>Fe edback</title></head>
    <body>

    <?php

    // Handle POST method.
    //if ($_POST)
    //{

    $name = $_POST['name'];
    $email = $_POST['email'];
    $comments = $_POST['comments'];

    // Compose simple text message:
    $message = "Message from $name
    ($email)\n\nCom ments:\n\n$comm ents";

    // Send message to bob@microsoft.c om
    mail("email@ema il.com", "Feedback", $message);

    // Thank the generous user
    echo "<h1>Cheers !</h1>\n";
    echo $_POST;
    echo $_POST['name'];
    echo $_GET['name'];
    // }
    //else
    //{
    echo($_POST);
    echo($_POST['name']);
    // mail("kreeemer@ hotmail.com", "Feedback", $message);

    echo("yo");
    ?>

    <h1>Feedback</h1>

    <form action="<?=$PHP _SELF ?>" method="Post">

    <p>Name: <input type="text" name="name" /></p>

    <p>Email: <input type="text" name="email" /></p>

    <p>Comments:</p>
    <p><textarea name="comments" ></textarea></p>

    <p><input type="submit" value="Send!" /></p>

    </form>

    <?php

    // }

    ?>

    </body>
    </html>

      Are you sure that you don't use an outdated PHP version?

              Superglobals ($_GET, $_POST, etc) are available at all scopes regardless of
              configuration, so this is odd.

              Couple of things that might help you in debugging this and everything else
              ever:
              1) When printing arrays, use print_r() instead of print() - this will expand
              the contents out instead of printing the oh-so-helpful "Array". I always
              prefix it with echo "<pre>"; and postfix with echo "</pre>"; to get the
              formatting right.
              2) Try using $_REQUEST to avoid any confusion about $_GET vs $_POST.
              3) Try turning error output on: error_reporting (E_ALL); in the first line of
              code under debugging.
              4) Try the following:
              echo "<pre>"; print_r($GLOBAL S); echo "</pre>";
              You ought to see SOMETHING in the output you recognise.

              HTH

                  What output *are* you getting? "echo $_POST" or "echo $_GET" should at
                  least print the word "Array" to the screen.

                  Is your code even being parsed through the PHP parser?

                  Try "View Source" in your browser to see.
