    get method

    I'm doing some tutorials with the book: PHP by example. The following
    program should according to the book, generates a personalized
    greeting for a visitor, but it doesn't. Any ideas why? Here's the
    code, in two seperate files:

    FIRST FILE (TEST1.PHP):

    <html>
    <head><title>We lcome!</title></head>
    <body>

    <form action="ch03ex1 1.php">

    What's your name? <input type="text" name="userName" >
    <input type="submit" value="Continue ">

    </form>

    </body>
    </html>


    SECOND FILE (CH02EX11.PHP):


    <html>
    <head><title>We lcome!<title></head>
    <body>

    <h4>
    Welcome, <?= $HTTP_get_VARS['name'] ?>!
    </h4>

    </body>
    </html>

      Most likely because register_global s in php.ini is set to off.

      Try to modify your code like this:

      Page 1:

      <Form action="ch03ex1 1.php" method="POST">

      Page 2:

      Welcome, <?php echo $_POST["userName"]; ?>

      .... i don't use shorttags, I go long tags thus <?php ...


      HTH,

          Oh yes ...

          if you want it to use GET, just replace POST with GET.

              Actually, the way that the poster is doing is still ok for register_global s
              = off. This was the way prior to 4.1.0 ($HTTP_GET_VARS , $HTTP_POST_VARS ).
              But to the poster: As of 4.2.x, these are now depreciated, and you should
              use $_GET, $_POST etc instead.


              The problem with the poster's code is that the form didn't specify a method.
              If you want to use GET vars, then you need to do <form method="get"
              action="whateve r">. You can't leave out the method.

                  [ ... ]
                  [color=blue][color=green][color=darkred]

                  There's two typos there, I think, or is that really how your book
                  reads? The name of your INPUT is "userName", not "name", so your
                  array key ought to be "userName". Variable names are case sensitive,
                  so the array name is $HTTP_GET_VARS, not $HTTP_get_VARS.

                  No. GET is the default value for the method attribute; if the method
                  attribute is omitted, GET is inferred.

                      Your form - when submitted, calls ch03ex11.php but the second file
                      you've submitted, you say is called cho02ex11.php

                      Thus - you've not said 'how' its not working (ie does it complain that a
                      file is missing, or some other text message perhaps belonging to a
                      different script?

                      The rest of the code is fine so I think its just a typo.

                      Hope the above helps, and stay with PHP - once you walk, you'll soon
                      learn to run...
