    PHP not parsing forms

    Here is the code that I used to test my server, very simple, right?
    But when I click on submit, nothing.. I've also tried similar things
    with php and mysql and all it did was create empty fields in the table.
    What am I doing wrong? Please help, Ultimatly I want to parse a form
    into a mysql database, but if I can't get the php engine to pass data
    from the forms correctly then it's no use to go any further.

    <?php

    if ($submit == "click"){
    echo "Hello, $UserName";
    }
    else{
    echo '
    <html><body>

    <form method="post" action="form.ph p">

    Enter Your Name
    <input type="text" name="UserName" ></input><br>

    <input type="submit" name="submit" value="click"></input>

    </form>

    </body></html>
    ';
    }

    ?>

      Your code doesn't work because register globals have been disabled. This is
      easily fixed by retrieving the post data explicitly.

      Add this to the top of your PHP code:

      $submit = $_POST['submit'];

      More info here: <http://uk.php.net/register_global s>

          Since 4.2.0 register_global s [1] is off by default due to security
          reasons [2]. One should use super globals (introduced in 4.1.0) instead
          to get to user supplied data [3]. So either fix:

          -fix your code [4]:
          if(isset($_POST['submit']) && $_POST['submit']=="click")
          {
          echo 'Hello, '.$_POST['UserName'];
          }
          -quick&dirty hack:
          extract($_REQUE ST);
          in the global scope.
          -enable register_global s

          1: http://www.php.net/manual/en/ini.cor...gister-globals
          2: http://www.php.net/manual/en/security.globals.php
          3: http://www.php.net/manual/en/languag...s.superglobals
          4: $_POST['UserName'] should offcourse be escaped properly (with
          htmlspecialchar s in this particular case).

              You probably have register_global s turned off (and you should).
              Put this in the beginning of your script:

              $UserName = $_POST['UserName'];
              $click = $_POST['click'];

              Cheers,
