Controller

    public function editItem(){
         $this->load->helper('form'); 
         $this->load->model('ItemModel'); 
         $data['items'] = $this->ItemModel->itemlist(); 
         $item_details = $this->ItemModel->edititem($this->input->get('id'));    
         $data2['item_name'] = $item_details->name; //THIS IS LINE 28
         $data2['item_description']= $item_details->description; 
         $data2['item_price'] = $item_details->price;
         $this->load->view('item/item_edit',$data2); 
    }

There's an error to my view, and I don't know why

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Item::$name

Filename: core/Model.php

Line Number: 77

Backtrace:

Line: 28
Function: __get

File: C:\xampp\htdocs\itwa213\index.php

I already checked my autoload on config and it's properly configured with

$autoload['libraries'] = array('database');

Answer 1

You could try this

public function editItem() {
     $this->load->helper('form'); 
     $this->load->model('ItemModel'); 

     $data['items'] = $this->ItemModel->itemlist(); 

     $item_details = $this->ItemModel->edititem($this->input->get('id'));    

     $data2['item_name'] = $item_details['name']; //THIS IS LINE 28
     $data2['item_description'] = $item_details['description']; 
     $data2['item_price'] = $item_details['price'];

     $this->load->view('item/item_edit',$data2); 
}

Answer 2

Your controller function change to like this

public function editItem(){ 
  $this->load->helper('form');
  $this->load->model('ItemModel');

  $data['items'] = $this->ItemModel->itemlist(); 
  $data2['item_details'] =$this->ItemModel->edititem($this->input->get('id')); 

  $this->load->view('item/item_edit',$data2); 
} 

and in your view page

echo $item_details->name;

You should look at your code for the get function you use. try to replace the $this->input->get('id') to existing id number first. check whether it success or not. If success by using existed id number, so it should your get function not working or something wrong. i'm seldom use $this->input->get() but $this->input->post().

on your edit link, you can use: <a href="controller/method/id">edit</a> . so the id is the third segment uri. use $this->uri->segment(3); to get the third segment and store into $item_id variable into your controller. so, no need to use $this->input->get(); to get the item_id value.
