[php]Confirm Email Before Download

this is my frist tut so dont hate on me!

1. Create a form where people can send ther email address at the bottom of the site's Terms Of Use page.
2. When the people agree to the Terms Of Use, they type in their email address and submit it.
3. After submitting, the owner of the site gets the visitor's email address and the visitor will receive an email (so it's important that the visitors send a valid email address) with the link to where the goodies can be downloaded.

Step 1: Submit Email Form
Let's assume that you have a Terms Of Use page named terms.php. Place this code after you've listed your terms:

PHP Code:

<center>
<form action="confirmemail.php" method="post">
<input type="text" name="Email" size="30">
<input type="submit" value="I AGREE">
</form>
</center> 

Step 2: confirmemail.php
Let's make a file called confirmemail.php. We'll put a script here where we confirm if the email submitted is valid. This is also where the fun part is: sending an email to the visitor (the URL) and the owner (the visitor's email).

PHP Code:

<?php

// CHECKS IF AN EMAIL ADDRESS IS VALID
if (!eregi('^(.+)@(.+)\.(.+)$', $Email))
{
// ERROR MESSAGE IF EMAIL IS INVALID
echo "<p>You didn't enter your email. Press
the back button of your browser and
try again.</p>";
}

else
{
// EMAIL FOR THE VISITOR

// SUBJECT OF THE EMAIL TO THE VISITOR
$VisitorSubject = "Confirm Email";

// TELLS THE VISITOR WHO IT'S FROM
$VisitorHeaders = "From: \"[u]DANNY[/u]\"
<[u]owner@mysite.com[/u]>\n";

// MESSAGE TO THE VISITOR WITH THE URL
$VisitorMessage = "[u]Thank you for your interest
in downloading my goodies.
Here's the link to them:
http://Gfx-depot.com[/u]";

// SEND EMAIL TO THE VISITOR
mail("$Email", "$VisitorSubject",
"$VisitorMessage", "$VisitorHeaders");


// EMAIL FOR THE OWNER

// OWNER'S EMAIL ADDRESS
$OwnerEmail = "owner@mysite.com";

// SUBJECT OF THE EMAIL TO THE OWNER
$OwnerSubject = "[u]Visitor Email[/u]";

// TELLS THE OWNER WHO IT'S FROM
$OwnerHeaders = "From: \"[u]Site Visitor[/u]\"
<$Email>\n";

// MESSAGE TO THE OWNER WITH VISITOR'S EMAIL
$OwnerMessage = "A visitor with this email,
$Email, [u]wants to download
your goodies.[/u]";

// SEND EMAIL TO THE OWNER
mail("$OwnerEmail", "$OwnerSubject",
"$OwnerMessage", "$OwnerHeaders"); 

// MESSAGE IN THE SITE FOR THE VISITORS
echo "[u]Thank you. The URL to download the
goodies was sent to your email.[/u]";
} 

?>
