Even if empty values ​​come from the form, your code will display a message about the successful addition of students to the database, but in fact they are not added. It is better to get rid of nesting (if->if->if). Checking for the existence of a non-empty variable is best done using isset(). Regarding Ajax, as far as I understand, you send it immediately after the page is loaded, so the data from the input is not transmitted.
