You sending the data in form with the "POST" method and you trying to get it with $_GET variable;
you can edit the form method to "get" :
<form action="input_db.php" method="get">
Or try to get the data with the $_POST["name"] variable
You set the method to POST in the form.
So you need to use POST["name"] instead of GET["name"] in your PHP
