PHP SCRIPT EXPLAINATION

This is the first time we work with php scripts, it's a lot of fun! I will post all my php source code at the end of this page! Pardon all my code, my time frame to complete this project is so tight, so I'm not using proper programming (law) as you can said. so you would be mad for a lot of shortcut I'm using in my code… PARDON! 😃 Nonetheless enjoy!

GetUsers.php

 
I use this script to fetch all the users in my database, why? because easier for me to create a scoreboard ingame. I also use this list to make comparison
for me to get logged in user credientials such as score

Login.php

 
Login will ask two parameter one is username and password, here we will detect if users are verified or not, also for password we use PHP passwordencrypt. So we are not comparing
the password directly.

Register.php

 
We will ask username, password, email, and OTP that have been random generated in C#
password send into database will be encrypted.
we also will check if username and email are already taken.
if the registration success we will send VERIFICATION EMAIL into their mailbox.

SendOTP.php

 
This is used to send OTP to user email, everytime user try to login with unverified account. OTP IS ENCRYPTED! :D

VerifyOTP.php

 
Verify of OTP are the same, using password_verify($row["otp"], $otp); to check if value are true or false.

ResetPassword.php

 
Request password reset, sended to user email.

VerifyOTP.php

 
ResetPasswordVerfiy, new password sended to user.

ChangePassword.php

 
User change password ingame

private void ifToggleOn() & public void toggleButton()

 
This method is used and called from toggle (REMEMBER ME BUTTON)

public void ButtonLogin()

 
This button will process login. Before we send login credentials to php, we do client-side credentials validator. 
this will check if string empty, length, contains spaces, email format valid or not.

public void ButtonRegister()

 
This button will process register. Before we send login credentials to php, we do client-side credentials validator. 
this will check if string empty, lenght, contains spaces, email format valid or not. This is also where we set user OTP code.

IsValidEmail(string email) & IsValidUsername(string username)

 
Using regex we see if email and username valid or not.

IEnumerator Login(string username, string password)

 
By using unity build in UnityWebRequest class we can post parameter into php. This is how we post and we retrieve back strings to check if it's valid or not.
IF ALL SUCCESS, WE WILL FIND USERS FROM USER List<string>() THAT HAVE BEEN GENERATED in SandBoxRequest.cs

IEnumerator StartCooldown()

 
If user not yet validate their account Login will automatically re-send OTP to their email, to avoid abuse we create a OTP cooldown.

Register(string username, string password, string email, int otp)

 
By using unity build in UnityWebRequest class we can post get parameter into php. This register is mostly the same with login method.

IEnumerator ResendVerification(string username)

 
method to resent verification

IEnumerator ButtonForgotPassword(string username)

 
method to run forgotpassword method

IEnumerator ForgotPassword(string email)

 
Forgot Password Logic! It will send the user email to validate, when they click that email, they will receive new password with that email, they can change password later ingame.
