无法在codeigniter控制器中获取POST数据

Question

For some reason I cant seem to get to post data in a codeigniter controller. I broke it down to a very simple form to test it out, still no luck. If I use method="get" it works fine. Anyways, below is the form, the controller/function, and my .htaccess. Any help would be much appreciated. Also, I saw a few other similar questions on here, but none of them seemed to have an answer that worked for me.

form:

<form id="bundleOrderInfo" name="bundleOrderInfo" action="<?php echo(base_url()); ?>catalog/bundleSubmit" method="post"> 

<input type="text" name ="test" id="test" value="blahblah"></input>
<input type="submit"></input>
</form>

controller/function:

    public function bundleSubmit()
{
   $this->output->enable_profiler();
   $this->load->model('catalog_model');

   $data['availableCategories']=$this->catalog_model->getCategories();
   $data['availableItems'] = $this->catalog_model->getByCategory($data['availableCategories']);
   $testing = $this->catalog_model->formData();

   $this->load->view('templates/header');
   $this->load->view('templates/menu',$data);

   print_r($_POST);
}

.htaccess:

<IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteBase /

   RewriteCond %{REQUEST_URI} ^system.*
   RewriteRule ^(.*)$ /ITPortal/index.php?/$1 [L]

   RewriteCond %{REQUEST_URI} ^application.*
   RewriteRule ^(.*)$ /index.php?/$1 [L]

   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule ^(.*)$ ITPortal/index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    ErrorDocument 404 /ITPortal/index.php
</IfModule>

action should direct to controller function, if you try FormHelper your life will be much easier

https://www.codeigniter.com/user_guide/helpers/form_helper.html

Try to load models,helpers, libraries at constructor [ __construct() function] it is a good proper way.

Controller

function __construct()
{
     parent:: __construct();
     $this->load->helper('form'); //loading form helper
     $this->load->model('catalog_model'); //loading your model
}

function bundleSubmit()
{
     $this->catalogmodel->insertFromForm();  //calling your method from model
}

Normally you should catch Posted Value in model

Model

  function insertFromForm()
  {
     $name= $this->input->post('name');
     print_r($name);
     die(); // stop the process here
  }

View

<?php echo form_open('catalog/bundleSubmit','id="bundleOrderInfo" name="bundleOrderInfo"') ;?>
//you can also do this , this should be enough 
//<?php echo form_open('catalog/bundleSubmit')?>

<input type="text" name ="test" id="test" value="blahblah"></input>
<input type="submit" value="Submit"></input>

<?php echo form_close();?>

Addition

'catalog/BundleSubmit' in form mean means your form posted values will goes to to 'controller/function()' and controller will redirect to a method in model 'model/insertDataFromForm"
