The php code works correctly and does not request the database

I'm using php and a database to add books to a database.

HTML

<form method="POST" action="addbook.php">
<p>Enter Book title :<input type="text" name="bookname"></p>
<p>Enter Book Author :<input type="text" name="bookauthor"></p>
<p><input type="submit" value="addbook"></p>
</form>

PHP

$bname = $_POST['bookname'];
$bauthor = $_POST['bookauthor'];
$dbcon = mysqli_connect('localhost','root','password','bookstore') or die('asd');

$dbquery = "INSERT INTO books (title,author) VALUES ($bname,$bauthor)";

mysqli_query($dbcon,$dbquery) or die('not queryed');

echo "Your book has been added to your online library";

I'm getting the reply ' not queryed'

---

try putting single quotes around the values

ie

$dbquery = "INSERT INTO books (title,author) VALUES ('$bname','$bauthor')";
