    Beginners problem

    Hi,

    I'm just beginning PHP programming. I have installed Apache 2.0.48 and
    PHP 4.3.3. The installation went well. Then I was trying a little example.

    HTML page:

    <html>
    <head>
    <title>test</title>
    </head>

    <body>

    <form action="test.ph p" method=POST>
    First Name: <input type=text name=firstname size=30
    MAXLENGTH=150>
    <input type=submit value="Send">
    </form>

    </body>
    </html>

    and the PHP script "test.php":

    <?php
    echo "First Name = ";
    echo $firstname;
    echo ".";
    ?>

    When I insert "Rolf" into the textfield and hit the "Send" button I get
    the response:

    First Name = .

    Nothing else. I thought that the variable $firstname is set to the
    string I inserted into the text field. Did I do anything wrong or could
    there be a problem with apache or php? I would be very appreciative for
    help on this problem.

    Regards

    Rolf Wester

    P.S.: When using method GET the form calls:
    http://localhost:8080/test.php?firstname=Rolf

    The Response is the same as before.

      Very common problem this. You have register_global s turned off, it's the
      default in recent releases of php.

      replace
      echo $firstname;
      with
      echo $_POST['firstname'];
      and all will be well

              Thanks a lot. It works now. Is it possible to turn register_global s on
              and if so how can I do it?

                  I wouldn't do that if I were you.
                  It's best to get into good habits from the start.
                  Globals on is a security risk.

                      Hi,

                      thanks to all for your help. I would like to turn on register_global s
                      mainly for the purpose of trying some sample-scripts downloaded from
                      somewhere that rely on this. I will use the more secure option
                      $_POST['**'] for my own scripts.

                      Regards

                      Rolf Wester
