I've got an existing project in code igniter and wanted to start using grocery crud with it. I'm running it on a recent install of wamp, php 5.4, apache 2.4.4.
I followed the basic set up, copy and pasting the files over to my code igniter directory and I set up a controller to display a table with crud functionality as in the tutorial, but I get the following error when viewing it:
Fatal error: Uncaught exception 'Exception' with message 'On the state "update" you must have post data' in C:\wamp\www...\application\libraries\Grocery_CRUD.php on line 3185
Controller:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Previousqualification extends CI_Controller {
function __construct(){
parent::__construct();
/* Standard Libraries of codeigniter are required */
$this->load->database();
$this->load->helper('url');
/* ------------------ */
$this->load->library('grocery_CRUD');
}
public function test(){
$this->grocery_crud->set_table('previousqualification');
$output = $this->grocery_crud->render();
$this->_crud($output);
}
function _crud($output = null){
$this->load->view('view_previousqualification.php',$output);
}
}
View as referenced in controller:

I've changed around my base url as I'd seen this may be the issue with somewhat similar errors. This had no effect. I do have mod_rewrite enabled in apache and .htaccess to get rid of index.php in the url - could this be an issue?
I've been looking at the file which causes the error (Grocery_CRUD.php) and it happens when I call the render() method, which calls a method getStateInfo() which calls another method that sets the state to 6 or 'update', this then checks if the $_POST variable is empty in getStateInfo() which I'm guessing it is because it throws the error. Why any of the aforementioned happens I'm unsure but was just my findings so far in trying to understand what exactly is going on. If you need any info please ask.
.htaccess file:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /codeIgniter
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
