mysql_query('INSERT INTO Form SET name="' . $_POST['name'] . '",email="' . $_POST['email'] . '",phone=' . $_POST['phone'] . ',message="' . $_POST['message'] . '"');
}
}
}
$q1 = new db;
$q1->base();
$q2 = new form;
$q2->postt();
?>

Answer 1

I'm not sure if it's main suspect, but action="site.com/formhandler.php" is the problem. action attribute needs path in one of two ways. With domain or without. With domain needs to start with http://. If there is no domain then it will append to the current url.
Examples (for let's say current url is http://example.com/users/):
action value what browser see
-------------------------------------------------------------------------
foo http://example.com/users/foo
foo.php http://example.com/users/foo.php
/foo.php http://example.com/foo.php
site.com/formhandler.php http://example.com/users/site.com/formhandler.php
Maybe it will show you some of mistakes :)
In my opinion you wanted one of these:
<form action="http://example.com/formhandler.php" method="POST">
<form action="/formhandler.php" method="POST"> -- script is in main webroot
<form action="formhandler.php" method="POST"> -- script is only in the same dir as current page

Answer 2

Please correct link to action (add http):
<form action="http://example.com/formhandler.php" method="POST">
Also you need to adjust php-code to avoid problems with security and database connection.
