I need to create a PHP file. Name the file work1.php

Include a form that allows the user to enter a book title, description, and price, and select a category from a drop-down list.

All form elements are required.

The price must be a positive number.

The form should be sticky (retaining any values previously entered by the user), and post to itself.

please I need this code by PHP with SQL, don\t use Java or others.

Thanks!
