I followed the instructions and downloaded the project, but when I run it in the browser there is only a white form what is the reason? $($it$\text{'}$s relevant to the answer to that question : "Hello, I need a project in php language and using MySQL$,$ with documentation for it$,$ and text explaining how to set up and run the project.

Project Requirements

$1.$ Project Overview:

Develop a web application where users can register, log in$,$ and create

and manage events.

Use object$-$oriented PHP to structure your code.

Implement secure password storage using hashing.

Use MySQL to store user and event information.

$2.$ Functional Requirements:

User Registration:

Create a registration form that collects the following

information:

$-$Username $($must be unique$)$

$-$ Password $($must be securely hashed$)$

$-$ Email address $($must be unique$)$

$-$Validate the input data for proper format and constraints.

$-$ Store the user data in a MySQL database.

$-$ User Login:

$-$ Create a login form that requires a username and password.

$-$ Validate the credentials against the stored data in the MySQL

database.

$-$ Start a user session upon successful login$.$

$-$ Event Management:

$-$ Allow logged$-$in users to create events with the following details:

$-$ Event name

$-$ Description

$-$ Date and time

$-$ Location

$-$ Store event data in the database.

$-$ Provide an interface to view, edit, and delete events.

$-$ Password Security:

$-$ Use PHP$\text{'}$s password$\_$hash$()$ function to hash passwords before

storing them.

$-$ Use PHP$\text{'}$s password$\_$verify$()$ function to verify passwords

during login$.$

$-$ Session Management:

$-$ Implement session handling to keep users logged in across

different pages.

$-$ Include a logout mechanism to end the session.

$3.$ Technical Requirements:

$$ PHP:

$$ Use classes and objects to structure the registration, login$,$ event

management, and session management functionalities.

$$ Create a class for database interactions using PDO $($PHP Data

Objects$)$ to handle MySQL queries.

$$ MySQL:

$$ Design a database with tables to store user information and

events $($e$.$g$.,$ users and events tables$).$

$$ Ensure proper relationships between tables $($e$.$g$.,$ user$\_$id in

events table to link events to users$).$

$$ Front$-$End:

$$ Create simple and user$-$friendly HTML forms for registration,

login$,$ and event management.

$$ Use basic CSS for styling $($optional$).$

$$ Security:

$$ Implement input validation to prevent SQL injection and XSS

attacks.

$$ Use HTTPS to secure data transmission $($if possible$).))$;

$4.$ Code Structure:

$$ Classes and Methods:

$$ Database: Class to handle database connection and queries.

$$ Methods: connect$(),$ query$(),$ execute$(),$ etc.

$$ User: Class to handle user$-$related operations.

$$ Methods: register$(),$ login$(),$ logout$(),$ isLoggedIn$(),$

etc.

$$ Event: Class to handle event$-$related operations.

$$ Methods: create$(),$ read$(),$ update$(),$ delete$(),$ etc.

$$ Session: Class to manage sessions.

$$ Methods: start$(),$ destroy$(),$ get$(),$ set$(),$ etc.

$$ File Organization:

$$ index.php: Home page.

$$ register.php: Registration form and handling.

$$ login$.$php: Login form and handling.

$$ logout$.$php: Logout handling.

$$ events.php: Interface to create, view, edit, and delete events.

$$ config.php: Configuration file for database connection.

$$ classes$/$: Directory for class files $($e$.$g$.,$ Database.php$,$

User.php$,$ Event.php$,$ Session.php$).")$
