Codeigniter : Loading data from multiple Models to a view
Question
I have the following view to List all products, and in that you can delete or edit a particular product, onclick of delete or edit it will call the controller,
<?php
$this->load->helper('url');
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>diluks eCommerce - Home</title>
<link href="<?php
echo base_url();
?>Public/scripts/style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<form action="<?php echo base_url();?>index.php/productlist_controller" method="post">
<div class="container">
<?php
include 'header-adminpanel.php';
?>
<div class="level3 clearfix">
<?php
include 'product-sidebar.php';
?>
<div class="body-content">
<div class="items">
<h2>Product List</h2>
<table class="CSSTable" cellspacing="0px" cellpadding="0px">
<tr>
<td>Item Code</td><td>Item Name</td><td>Item Price</td><td>Edit</td><td>Delete</td>
</tr>
<?php foreach($products as $row): ?>
<form method="POST" action="<?php echo base_url();?>index.php/productlist_controller">
<tr>
<td><?php echo $row->itemcode; ?></td><td><?php echo $row->itemname; ?></td><td>$<?php echo $row->itemprice; ?></td><td><center><button name="btn_edit" class="link-button" value="<?php echo $row->itemcode; ?>" type="submit">Edit</button></center></td><td><center><button name="btn_delete" class="link-button" value="<?php echo $row->itemcode; ?>" type="submit">Delete</button></center></td>
</tr>
</form>
<?php endforeach ?>
</table>
</div>
</div>
</div>
<div style="clear:both"></div>
<div class="level4">
<div class="footer-area">
<div class="lined-space"></div>
<div class="site-map" align="left">
<table>
<tr>
<td class="footer-text"><a href="#">About Us</a></td>
<td class="footer-text"><a href="#">Facebook</a></td>
</tr>
<tr>
<td class="footer-text"><a href="#">Contact Us</a></td>
<td class="footer-text"><a href="#">Twitter</a></td>
</tr>
<tr>
<td class="footer-text"><a href="#">FAQs</a></td>
<td class="footer-text"><a href="#">Terms & Conditions</a></td>

</div>
</div>
</div>
</div>
</form>
</body>
</html>
So the controller to the above view look like belo
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Productlist_controller extends CI_Controller {
function __construct(){
parent::__construct();
}
public function index()
{
if(isset($_POST["btn_delete"])){
$pid = $_POST["btn_delete"];
$this->load->model('product_model');
$result = $this->product_model->deleteProduct($pid);
if($result==true){
$data = array();
$this->load->model('product_model');
$data['products'] = $this->product_model->availableProductList();
$this->load->view('admin_product_list_view',$data);
}
else{
echo "Oops! Error occured..!";
}
}
else if(isset($_POST["btn_edit"])){
$pid = $_POST["btn_edit"];
$data = array();
$this->load->model('product_model');
$data['product'] = $this->product_model->readProduct($pid);
//$this->load->model('category_model');
//$data['categories'] = $this->category_model->getCategories();
$this->load->view('admin_product_edit_view', $data);
}
}
}
"admin_product_edit_view" which the user will be redirected onclick of edit for an particular item is as follows,
<?php
$this->load->helper('url');
?>

Now the problem is in the controller i need to load up categories (which I have commented) in order to show them in the edit view, but when I un-commented it, categories are loading, but Gives an Error in Item Description textarea saying
Message: Undefined property: stdClass::$itemdesc
With the category model loading line commented, it works fine except no categories will load up in the dropdownlist,Please someone suggest me a way to get rid of this.

Please use this in your view
if(isset($row->itemdesc)) echo $row->itemdesc;
I think this will solve your problem

I saw that you got an answer but i have a few suggestions for your code:
1. in your controller you load the model 3 times: you should load it once; you could do something like this:
if(!empty($_POST)){
$this->load->model('product_model');
if(isset($_POST["btn_delete"])){
//some code
}elseif(isset($_POST["btn_edit"])){
//some other code
}
}
2. in your views you load a helper: this should be loaded into the controller, right after the first verification from point 1.
3. in views you should check your variable for content, especially the ones that you are going to use in a loop, like $products
