A problem with variables?

[Tuuska]

Hello!

Please help a newbie in PHP... I have a problem with variables.

I have a website which has a form. Form asks for an email-address:

<form action="conf.ph p" method="post">
email : <input type"text" name="email">
</form>

Variable $email works fine in conf.php but what do I have to do to
make the same $email work in other xxxxxx.php -sites?

Thanks.

Tuuska

$email will only be defined in the php page specified in the form action
property, it will not exist in any other php pages on the site, especially
if the form is submitted via the POST method.

If you want to transfer the value of $email from the form action page to
other php pages, you could use session variables, or a database, or an XML
file to store the value.

Also you ought to use $_POST["email"] or $HTTP_POST_VARS["email"] when you
try to read the form variables.

(use $_GET["email"] for the 'GET' submission method)

This is a result of the register_global s property in php.ini being set to
'off' by default since php version 4.3 was introduced. This measure was
taken to improve the security of php scripts.

Your options are: (1) continue to pass it between pages via GET or
POST, (2) store it in a session variable, or (3) store it in a cookie.

Re: A problem with variables?

by -sites do you mean pages ?

Put this in your form page, which is php?
<?PHP
session_start() ;
?>

Put this in any other page.
<?PHP
session_start() ;
?>
<?PHP
$email2 = $_POST['email'];
//and you can check if you got it ok
echo $email2;
?>
