    Wampserver 2.0 and php

    Hi,
    I´ve just started using php, and i´m trying to make it work with wampserver!
    I´m using wamperver 2 , PHP 5.30
    on windows 7


    I have installed wampserver correctly and the localhost seems to work.
    When i try this script:

    <?php echo "something" ?>
    It works!

    But when I try to send information from a html file to php file, the varibel doesn't go throw. I get this message: Notice: Undefined variable: name in C:\wamp\www\php \results.php on line 3

    Please guys help me out :(



    Code:
    <html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title> Connect To Database</title>
</head>
<body>

<form action="results.php" method="post">
<input name="name" type="text" value="name">
<input name="" type="submit" value="search">
</form>

</body>
</html>
    Code:
    <?php
echo $name;
?>

      The form uses the method "post," as you can see in the <form> element's attributes. So, you will find the values from the form in the $_POST superglobal array in PHP.

      Code:
      if (!empty($_POST)) { // A form has been submitted
    if (!empty($_POST['name'])) {
        echo $_POST['name'];
    }
}

              Try to print_r() the $_POST array to see if anything has been submitted.

              Code:
              print_r($_POST);

                  No, nothing.

                  I tried this:

                  Code:
                  <?
if (!empty($_POST)) { // A form has been submitted
     if (!empty($_POST['name'])) {
      echo $_POST['name'];
    }
 }

print_r($_POST);
?>

                      Then that means that nothing has been submitted. The $_POST array only has data after you press the submit button on a form that posts to the page.

                          Ok, I see. But script is right for both php and html right?
                          So what is the problem then, what have i done wrong?

                          As I said before when i just "echo" something it does show up..
                          But of course I understand it´s difficult for you to point the problem out with the information provided by me.

                          Thanks anywaym, please let me know if you get an new idea =)

                              What I'm trying to tell you is that you have to test this page AFTER pressing the submit button...

                              A better way to do it is to keep it in the same page:

                              Code:
                              <?php
print_r($_POST);
?>
<form method="post" action="#">
  <input type="text" name="name" value="" />
  <button type="submit">Submit</button>
</form>

                                  ok sorry, didn´t understand that. This is very new for me =p

                                  I tried that out and got this message in the browser when I typed hello;
                                  Array ( [name] => hello )

                                      Good. That means that if you echo $_POST['name'], it would output "hello."

                                          yes it does, it (action = "#") but not when send it to another page.
                                          But I can live with that for now I guess.

                                          thanks a lot =D

                                              It should work fine going from one page to another. Not sure what went wrong with yours, but it is still common practice to submit forms to the same page

                                                  I dont know why it doesn´t work, I use this script for the html and php file:

                                                  Code:
                                                  <body>
<?php
echo $_POST['name']
?>

<form action="#" method="post">
<input name="name" type="text" value="name">
<input name="" type="submit" value="search">
</form>

</body>
                                                  Code:
                                                  <?
if (!empty($_POST)) { // A form has been submitted
     if (!empty($_POST['name'])) {
      echo $_POST['name'];
    }
 }
echo $_POST['name']
?>

                                                      The "action" attribute of the <form> element must correspond to the file that should be receiving the data.
