The jQuery part is often quite simple. It just redirects the ordinary form action= over a Javascript handler. $.post is easy to use and you just need .serialize() to package up the existing form values into a string:

And on PHP side you simply receive the content via $_POST and save it to the database (using the old mysql_ functions would also be possible, just more cumbersome):

$db = new PDO("mysql:...");

if ($_POST["submitbuttonname"]) {

   $q = $db->prepare("INSERT INTO save (textbox, label) VALUES (?, ?)";
   $q->execute(array($_POST["textbox"], $_POST["label"]));
