Displaying Username After Login (is this possible)?

Questions & Answers
1

Hello again! I would like to ask again, but this time, it is about displaying the username who logged into the game. What I did is that I wrote a PHP code that will fetch the username and then used UnityWebRequest.Get() to let the C# script read the PHP file, but then - no success. What only happens is that there is no name displayed on the Welcome Screen.

Here are my codes:

  1. LoginInputs

    //Variables
    public InputField UsernameInput;
    public InputField PasswordInput;
    public Button LoginButton;
    public Text message;

    public void FieldCheckLogin() {
    /LoginButton.onClick.AddListener(() => {
    StartCoroutine(Main.Instance.Web.Login(UsernameInput.text, PasswordInput.text));
    });    /
    message.text = “”;
    StartCoroutine(Login(UsernameInput.text, PasswordInput.text));
    }

    public IEnumerator Login(string username, string password)
    {
    WWWForm form = new WWWForm();
    form.AddField(“loginUser”, username);
    form.AddField(“loginPass”, password);

     using (UnityWebRequest www = UnityWebRequest.Post("http://localhost/sqlconnect-ChemAR/login.php", form))
 {
     yield return www.SendWebRequest();

     if (www.isNetworkError || www.isHttpError)
     {
         Debug.Log(www.error);
         message.text = www.error;
     }
     else
     {
         Debug.Log(www.downloadHandler.text);
         StartCoroutine(GetDate());
         message.text = www.downloadHandler.text;
     }
 }

    }

    IEnumerator GetDate()
    {
    using (UnityWebRequest www = UnityWebRequest.Get(“http://localhost/sqlconnect-ChemAR/GetDate.php”))
    {
    // Request and wait for the desired page.
    yield return www.Send();

         if (www.isNetworkError || www.isHttpError)
     {
         Debug.Log(www.error);
         message.text = www.error;
     }
     else
     {
         //Show results as text
         Debug.Log(www.downloadHandler.text);

         //Or retrieve results as binary data
         byte[] results = www.downloadHandler.data;
         StartCoroutine(PleaseWait());
         SceneManager.LoadScene(3);
     }
 }

    }

    IEnumerator PleaseWait() {
    yield return new WaitForSeconds(5);
    }

    public void VerifyInputsLogin() {
    LoginButton.interactable = (UsernameInput.text.Length >= 8 && PasswordInput.text.Length >= 8);
    }

    /Conditions if the username and password are correct or not
    public void FieldCheckLogin() {
    if (UsernameInput.text == “” || PasswordInput.text == “”)
    {
    message.text = “Please don’t leave any of the fields blank.”;
    }
    }    /

    //Other Login Inputs will soon to be included (I need to setup a database first.)

  2. UsernameDisplay

    //Variables
    public Text UserDisplay;

    // Start is called before the first frame update
    void Start()
    {
    StartCoroutine(GetUsername());
    }

    IEnumerator GetUsername() {
    using (UnityWebRequest www = UnityWebRequest.Get(“http://localhost/sqlconnect-ChemAR/displayuserlogged.php”)) {
    yield return www.Send();

         if (www.isNetworkError || www.isHttpError)
     {
         Debug.Log(www.error);
     }
     else
     {
         //Show results as text
         Debug.Log(www.downloadHandler.text);

         //Or retrieve results as binary data
         byte[] results = www.downloadHandler.data;
     }
 }

    }

Its better to write a logic like this,

once after you submit the data to your server and you get a success message…
Just add the login name to a PlayerPrefs and retrieve it and show it in the display.

 byte[] results = www.downloadHandler.data;

if(www.downloadHandler.data.ToString().Contains("Success")
{
   PlayerPrefs.SetString("UID", name);
}

Retrieve the data and show it anywhere like this,

loginName.text = "Hi " + PlayerPrefs.GetString("UID") + "!";

Let me know if this helps you.
