仅在一个页面上的Codeigniter 404错误

Question

Okay, so I have created a website using php and codeigniter, also using nosql. All my pages are working except for one.

I have checked everything in the dashboard controller and it looks like it should work, yet every time i try and link to the page i get the 404 error and this also happens when i type in the url manually.

Any ideas on what this could be?

Here is what's in the dashboard

        public function Result() {
        $this->load->helper('url');
        $this->load->view("site_header");
        $this->load->view("site_navigation");
        $this->load->view("content_result");

           }

And here is where it's being linked to from another page within a form

    <form action='content_result.php?id=1' method='post' id='quizForm' id='1'>

Controller Code:

    <?php
     defined('BASEPATH') OR exit('No direct script access allowed');

  class Welcome extends CI_Controller {

public function index()
{
    $this->home();        }

    public function home() {
        $this->load->helper('url');
        $this->load->view("site_header");
        $this->load->view("site_navigation");
        $this->load->view("content_home");  
    }

    public function login() {
        $this->load->helper('url');
        $this->load->view("site_header");
        $this->load->view("site_navigation");
        $this->load->view("content_login");

    }

    public function register() {
        $this->load->helper('url');
        $this->load->view("site_header");
        $this->load->view("site_navigation");
        $this->load->view("content_register");

    }
   public function Quiz() {
        $this->load->helper('url');
        $this->load->view("site_header");
        $this->load->view("site_navigation");
        $this->load->view("content_Quiz");

    }

        public function Quizpage() {
        $this->load->helper('url');
        $this->load->view("site_header");
        $this->load->view("site_navigation");
        $this->load->view("content_quizpage");

    }

        public function Result() {
        $this->load->helper('url');
        $this->load->view("site_header");
        $this->load->view("site_navigation");
        $this->load->view("content_result");

    }

    }

Routes.php:

    $route['default_controller'] = 'welcome';
    $route['404_override'] = '';
    $route['translate_uri_dashes'] = FALSE;

View:

    <div id="container">

    <h1>Quiz</h1>

   <div id="content">

    <?php

//Creating random number s
$rid = rand(1,3);
echo $rid;
?>

<?php

 if ($rid == 1){

  echo "
  <form class="addinvestmentform" action="<?php echo base_url();?>index.php/Welcome/result" method='post' id='quizForm' id='1'/>

   <input type="hidden" name="id" value="1"/>
   <ol>

    <li>
    <h3>What does PHP stand for?</h3>

    <div>
    <input type='radio' name='answerOne' id='answerOne' value='A' />
    <label for='answerOneA'>A) Hyper text markup language</label>
    </div>

    <div>
    <input type='radio' name='answerOne' id='answerOne' value='B' />
    <label for='answerOneB'>B) PHP: Preprocessed hypertext</label>
    </div>

    <div>
    <input type='radio' name='answerOne' id='answerOne' value='C' />
    <label for='answerOneC'>C) PHP: Hypertext Preprocessor</label>
    </div>
    </li>

Answer 1

Use base_url() and keep parameter in hidden file

    <form class="addinvestmentform" action="<?php echo base_url();?>index.php/controller_name/function" method='post' id='quizForm' id='1'/>

    <input type="hidden" name="id" value="1"/>
    </form>

And change your view code to 

<h1>Quiz</h1>

<?php

//Creating random number s
$rid = rand(1,3);
echo $rid;
?>

<?php

 if ($rid == 1){
?>

  <form class="addinvestmentform" action="<?php echo base_url();?>index.php/Welcome/result" method='post' id='quizForm' id='1'/>

   <input type="hidden" name="id" value="1"/>
   <ol>

    <li>
    <h3>What does PHP stand for?</h3>

    <div>
    <input type='radio' name='answerOne' id='answerOne' value='A' />
    <label for='answerOneA'>A) Hyper text markup language</label>
    </div>

    <div>
    <input type='radio' name='answerOne' id='answerOne' value='B' />
    <label for='answerOneB'>B) PHP: Preprocessed hypertext</label>
    </div>

    <div>
    <input type='radio' name='answerOne' id='answerOne' value='C' />
    <label for='answerOneC'>C) PHP: Hypertext Preprocessor</label>
    </div>
    </li>
</form>
<?php } ?>
