You made a from like this:
<FORM ACTION="post.php" METHOD="POST">
<INPUT type="hidden" name="user" value="somebody">
<INPUT type="hidden" name="redirect" value="
<INPUT type="text" name="email">
<INPUT type="submit" value="send">
</FORM>
By this form a user called somebody must type in his emailadres. This is send to the post.php script
You can also use METHOD="GET" but you will see the passing variable then in your location bar of the browser.
At least you made the post.php site:
now you can use the variable names. They have the same name as the name of the INPUT areas.
<?php
echo($user); // Let you see: somebody
echo($email); // Let you see the value the user of the form gives.
// Now you can use some php who redirect to the page:
$redirect
?>
Hope this will help you,
