我有以下看法列出所有產品，並可以刪除或編輯特定的產品，的onclick的刪除或編輯，它會調用控制器，笨：從多個模型到視圖加載數據
<?php
$this->load->helper('url');
?>

所以控制器在上述視圖看起來像貝洛
<?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」，用戶將被重定向編輯的onclick用於特定項目如下，
<?php
$this->load->helper('url');
?>

現在問題是在控制器我需要加載類別（我已評論），以顯示他們在編輯視圖中，但是當我un-comment它，類別加載，但給出錯誤項目說明textarea的話說
Message: Undefined property: stdClass::$itemdesc
隨着分類模型加載線評論道，它工作得很好，除了沒有類別將在下拉列表加載，請有人建議我的方式來擺脫這一點。
錯誤沒有顯示出來，而且還有數據，通過註釋這些行來正確加載項目描述，但是當未評論，它加載的類別很好，但沒有物品描述 –
將您的可變名稱$ row更改爲其他某些東西 像$ categroy您已經使用$ row作爲其他數據，這將覆蓋其他變量 foreach（$ categories as $ row） –
它工作正常！非常感謝Sohail，這是錯誤的。 –
