Hello,

Could you help me with this problem please?
In which way should I use the following 2 scripts:

Listing 10-2: A simple form
<html>
<head>
<title>Listing 10-2</title>
</head>
<body bgcolor="#ffffff" text="#000000" link="#cbda74" vlink="#808040"
alink="#808040">
<form action="listing10-3.php" method="post">
<b>Give us some information!</b><br>
Your Name:<br>
<input type="text" name="name" size="20" maxlength="20" value=""><br>
Your Email:<br>
<input type="text" name="email" size="20" maxlength="40" value=""><br>
<input type="submit" value="go!">
</form>
</body>
</html>

Listing 10-3: Displaying the data collected in Listing 10-2
<html>
<head>
<title>Listing 10-3</title>
</head>
<body bgcolor="#ffffff" text="#000000" link="#cbda74" vlink="#808040"
alink="#808040">
<?
// output the user's name and email address.
print "Hi, $name!. Your email address is $email";
?>
</body>
</html>

I've saved them as a 2 php files, listing10-2.php and listing10-3.php in my localhost folder.
I've called listing10-2.php through my localhost, and have got the form.
When I fill the form and press the 'go!' button, I get "Hi, !. Your email address is".
So why the variables $name and $email haven't been passed ?



Thanks

Hi discus,

Use print "Hi, ".$_POST['name']."!. Your email address is ".$_POST['email'];

If you used the get method then you'd use $_GET['name']

Hope that helps,

Neil

Thanks Neil.

That has helped indeed.

But I'm just wondering why the author of this book (Programmers Introduction To PHP4) W.J.Gilmore, didn't put that in the script ?
Is that something about PHP versions (maybe newer versions require that, and older ones not)?

It's actually dependent on the "register globals" setting on the server. With "register globals" enabled, you could use "$name" and "$email". "Register globals" was ON by default in PHP versions before 4.2, and OFF by default after. With "Register globals" OFF, you have to use the Superglobal arrays $_POST[], $_GET[], $_REQUEST[], etc. If you want to check the server configuration, just create a quick PHP script like this and it will reveal most everything:

<?php

echo phpinfo();

?>
