What can I do with my C# code for me to apply this to my UI in Unity?

Question

I'm trying to set up my Account registration system to input data from unity to my database, and so far i have been able to do so through the Inspector, now I want to be able to do this with my UI that i made in Unity, what do I need to do? (P.S. this is my first time posting and i am also a beginner so excuse me if i may not follow some rules and what not)

here is the code i used to input data to my PhpMyAdmin database through the inspector in Unity:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DataInserter : MonoBehaviour
{

    public GameObject inputUserName;
    public GameObject inputEmail;

    string CreateUserURL = "http://localhost/balikaral/insertAccount.php";

    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
       if (Input.GetKeyDown(KeyCode.Space)) CreateUser(inputUserName, inputEmail);
    }

    public void CreateUser(string username, string email)
    {
        WWWForm form = new WWWForm();
        form.AddField("usernamePost", username);
        form.AddField("emailPost", email);

        WWW www = new WWW(CreateUserURL, form);
    }
}

You simply have to get the input from your input fields InputField.text

I recommend to directly use InputField fields so you don't need the GetComponent calls.

public class DataInserter : MonoBehaviour
{
    public InputField inputUserName;
    public InputField inputEmail;

    string CreateUserURL = "http://localhost/balikaral/insertAccount.php";

    public void CreateUser()
    {
        var userName = inputUserName.text;
        var email = inputEmail.text;

        WWWForm form = new WWWForm();
        form.AddField("usernamePost", username);
        form.AddField("emailPost", email);

        WWW www = new WWW(CreateUserURL, form);
    }
}

And reference the CreateUser method in the Button's onClick event.

Note however that WWW is obsolete and you should rather use UnityWebRequest.Post

public void CreateUser()
{
    var userName = inputUserName.text;
    var email = inputEmail.text;
    StartCoroutine(CreateUserRequest(userName, email));
}

private IEnumerator CreateUserRequest(string userName, string email)
{
    WWWForm form = new WWWForm();
    form.AddField("usernamePost", username);
    form.AddField("emailPost", email);

    using (UnityWebRequest www = UnityWebRequest.Post(CreateUserURL, form))
    {
        yield return www.SendWebRequest();

        if (www.isNetworkError || www.isHttpError)
        {
            Debug.Log(www.error);
        }
        else
        {
            Debug.Log("Form upload complete!");
        }
    }
}
