php - CodeIgniter controller method not responding


I have a codeigniter application that is effectively just a one-page form that takes in info and sends an e-mail. I created a method that is intended to handle form submission and send the e-mail called "submit", but for some reason this method appears not to do anything at all.

Here's my controller code:

class Main extends CI_Controller {

public function __construct() {

public function index($page = "home") {
    // Loading the form view.

// This is the method that doesn't do anything.
public function submit() {

    // I would be processing post data from the form here, 
    // but right now I'm just trying to load 
    // a view in this method to see if it's working

My view is using the CodeIgniter form_open function to create the form, and looks as follows:

echo form_open("main/submit/");

This, to my understanding, is how one is supposed to use the form_open function to provide an action to the form.

The form opening tag looks like this when the view is accesssed.

<form action="http://localhost:81/project1/main/submit" method="post" accept-charset="utf-8">

The action and method in the form tag appears to be correctly set, but when clicking on submit on the form the home view just refreshes. Additionally, if I try to directly navigate to "home/submit/" it just loads the home view again. I'm starting to go a little crazy on this and I'm sure I'm missing something really simple.
