Keeps running else statement even though it shouldn't
So I wrote some code to use as a Log In system in my 2D game. But whenever the button is clicked upon, the else statement that shouldn't be triggered triggers. I later found out it was because the strings the if statement compared weren't filled in the first time when clicking. So I added some sort of loop. This doesn't work for some reason and I have no idea why. If anyone knows how I could fix this please tell me. Thanks in advance.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class Login : MonoBehaviour
{
public string databaseUsername;
public string databasePassword;
public Button Continue;
public InputField Username;
public InputField Password;
public string inputPassword;
private int Teller = 0;
string LoginUrl = "localhost:8080/Logingegevens.php";
// Use this for initialization
void Start()
{
//functie oproepen als er op aangegeven knop gedrukt wordt.
Button btn = Continue.GetComponent<Button>();
btn.onClick.AddListener(TaskOnClick);
}
public IEnumerator Loggingin(string Username)
{
WWWForm form = new WWWForm();
form.AddField("inlogusernamePost", Username);
WWW www = new WWW(LoginUrl, form);
yield return www;
databasePassword = www.text;
}
// functie van button
void TaskOnClick()
{
StartCoroutine(Loggingin(Username.text));
if (Password.text == databasePassword)
{
SceneManager.LoadScene("PROTOTYPE");
} else {
if (Teller == 0)
{
Teller++;
TaskOnClick();
} else
{
SceneManager.LoadScene("Log in");
}
}
}
}

Uhm your coroutine runs seperately from the calling method. So this line
if (Password.text == databasePassword)
is executed way before you reach this line in your coroutine:
databasePassword = www.text;
Therefore your "databasePassword" variable won't be initialized. This whole concept doesn't make much sense. You transmit the password that is stored online as plaintext to anyone who accesses your "login URL". Any login online process works the other way round. You send the password the user enters to your server and verify the password on the server.
Any way to make sure the coroutine finishes before the if statement gets executed? The concept may not make a lot of sense but I understand it this way.
