Why does this code break my view?

[eluser]Chad Crowell[/eluser]
With this in my controller, the form view displays fine:

Code:

<?php
class Sell extends Controller {

function index()
{

  $data['title']    = "RunwayJunkie.com - Buy & Sell Designer Clothing";

  $data['templates']   = array("front/templates/header", "front/partials/item_addform", "front/templates/footer");
  
  $this->load->view('front/loader', $data);
}
  
}
?>

However, the second function, to collect the form data, keeps the form view from showing up. I can't figure out whats wrong.

Code:

<?php
class Sell extends Controller {

function index()
{

  $data['title']    = "RunwayJunkie.com - Buy & Sell Designer Clothing";

  $data['templates']   = array("front/templates/header", "front/partials/item_addform", "front/templates/footer");
  
  $this->load->view('front/loader', $data);
}



function insert_item()
{

  $data = array(
   'seller_id'   = '1';
   'category_id'   = $this->input->post('category_id', TRUE);
   'brand_id'   = $this->input->post('brand_id', TRUE);
   'size_id'   = $this->input->post('size_id', TRUE);
   'item_title'  = $this->input->post('item_title', TRUE);
   'item_desc_short' = $this->input->post('item_desc_short', TRUE);
   'item_desc_long' = $this->input->post('item_desc_long', TRUE);
   'price'    = $this->input->post('price', TRUE);
   'condition_id'  = $this->input->post('condition_id', TRUE);
   'color'    = $this->input->post('color', TRUE);
   'material'   = $this->input->post('material', TRUE);
   'measurements'  = $this->input->post('measurements', TRUE);
   'img_1'    = '1';
   'img_2'    = '2';
   'img_3'    = '3';
   'img_4'    = '4';
  );
  
  $this->db->insert('items', $data);
  
}

}
?>

This sort of thing is so frustrating- in the time its taken me to build 3 pages in CI, I could have built this client's entire app in dreamweaver...
