Question

Html working with PHP

Answer 1

You should use AJAX. Or you can write the page itself in the action attribute of the form and evaluate the data at the beginning of the code. It depends on what you need to do.

Of course, you must still establish the connection to the database and write the corresponding query.

You can find the official documentation on connection to databases in the following link: https://www.php.net/manual/es/refs.database.php
