Implementation of a web application for a library website. The application contains several pages with functions such as registration and log in options, the creation, search and rating of books, and wish lists. All functions are listed in the table below. AJAX applications were written to implement user-related actions, for example when searching for a book. A MySQL database runs in the background. It contains four tables for the users, the books, the ratings and the wish lists.


Please note that all text on the pages is written in German. However, the code is commented in English. The repository contains a sitemap PDF that gives an overview of the web pages and functions.

To run the application, XAMPP ( must be installed and the Apache and MySQL modules must be started. The repository must be stored under C:\xampp\htdocs. The databases in the backend can be accessed in any web browser via http://localhost/phpmyadmin. Before starting the application, a new database with the name mybib must be created there! The application can then be accessed in a web browser via http://localhost/repository-name/start.php. It is necessary to call start.php first when starting the application for the first time in order to create the necessary tables!

The application comes with admin access. The access details are: Email: Password: 12345. The admin has special rights such as creating new books or organising user accounts.

Folder structure:
