Getting input field value in unity then Debug.Log ing it - unity3d

Question

I am creating a test project in Unity & I have an input field and a button. I would like to take the text from the input and simply Debug.Log to the Unity Console onclick of a button. All the examples show the variables and functions but don't show HOW they are getting the input to the variable. I already have UI set up including linking the function to the button. Is there some way I can give it an id like in JavaScript & HTML? I dont want to do anything fancy. Here is my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class main : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
}
public void debugInput() {
Debug.Log()
}
}
I would like to pass the variable in the Debug.Log in the debugInput function.
Can someone help me?
Thanks in advance

The InputField uses a callback for entering text to an input field called OnSubmit. If you would rather print every frame the user enters new text, there is also OnValueChanged.
These callbacks can be assigned in the inspector by selecting your InputField object. The inspector should look something like the below photo.
Simply click the + button, drag in the object that has the script that has the method you would like to callback. Make sure when selecting it to choose it from the Dynamic String list as it will auto pass in the string you have in the InputField to your function. You will need to change your code to take a string parameter tho.
public void debugInput(string str)
{
Debug.Log(str)
}
If you would rather set these values through code, you can do so by adding new listener delegates to your object. I can post a snippet for this solution if you would rather keep everything in a script.
Edit: I am using a TMPro Input Field, but the above example still works for a Unity UI Input Field. Instead of OnSubmit, you can use OnEndEdit. You can also add your own EventTriggers to use OnSubmit if you want.
