Codeigniter can't access colum from database - php

Question

I tried to add 1 more column in my code, the column "itemid" to be used but I get strange error when I did everything how its supposed, the error message: "Undefined index: item_id".
My model:
function __construct() {
$this->proTable = 'web_store';
$this->transTable = 'purchases_users';
$this->GameRewards = 'users_items';
}
/*
* Fetch products data from the database
* #param id returns a single record if specified, otherwise all records
*/
public function getRows($id = ''){
$this->db->select('*');
$this->db->from($this->proTable);
$this->db->where('status', '1');
if($id){
$this->db->where('id', $id);
$query = $this->db->get();
$result = $query->row_array();
}else{
$this->db->order_by('Title', 'asc');
$query = $this->db->get();
$result = $query->result_array();
}
// return fetched data
return !empty($result)?$result:false;
}
/*
* Insert data in the database
* #param data array
*/
public function insertTransaction($data){
$insert = $this->db->insert($this->transTable,$data);
return $insert?true:false;
}
/*
* Insert data in the database
* #param data array
*/
public function insertGameRewards($data){
$insert = $this->db->insert($this->GameRewards,$data);
return $insert?true:false;
}
My Paypal controller:
function __construct(){
parent::__construct();
$this->load->library('paypal_lib');
$this->load->model('product');
}
function success(){
// Get user session (is it logged in the webpage)
$Session = $this->session->userdata("Player_Logged");
if($Session) {
// Get the transaction data
$paypalInfo = $this->input->post();
$data['item_name']= $paypalInfo['item_name'];
$data['item_number']= $paypalInfo['item_number'];
$data['item_idr']= $paypalInfo['item_idr'];
$data['txn_id'] = $paypalInfo["txn_id"];
$data['payment_amt'] = $paypalInfo["payment_gross"];
$data['currency_code'] = $paypalInfo["mc_currency"];
$data['status'] = $paypalInfo["payment_status"];
// Get user ID from 'users' table.
$IGN = $this->session->userdata['Player_Logged']['id'];
// Pass the transaction data to view
$this->load->view('paypal/success', $data);
// Insert the transaction data in the database
// This "custom" is old method by documentation, updated by me :P ('user_id' is 'UserID' [I changed column name in database])
//$datatobase['user_id'] = $paypalInfo["custom"];

$rewardstobase['EnhID'] = "1957";
$rewardstobase['Equipped'] = "0";
$rewardstobase['Quantity'] = "1";
$rewardstobase['Bank'] = "0";
// Insert the transaction data in the database
$this->product->insertTransaction($datatobase);

$this->product->insertGameRewards($rewardstobase);
} else {

function cancel(){

function ipn(){

$paypalInfo = $this->input->post();
if(!empty($paypalInfo)){

I tried to add new field 'item_idr' and get column 'itemid' with the same method how other fields are get by this library but it didn't work. I get error message. Even more details of the error message I get:
Severity: Notice
Message: Undefined index: item_idr

Answer 1

Maybe you don't have the control named "item_idr" in your view.
In Paypal.php at line
data['item_idr']= $paypalInfo['item_idr'];
it takes info from
$paypalInfo = $this->input->post();
As a side note, you can use CI form library (see CI documentation for form helper here) to extract the $_POST values, so you can benefit from form validation and sanitation of entries.
Anyways... coming back...
you are taking $_POST['item_idr'] and that is the error you get. So it is unrelated to your table and database, but related to the fact that your view doesn't have any
<input type="text" name="item_idr" id="item_idr">
or similar
