accessing specific page with some criteria in opencart - opencart

Question

I have a specific information page (page id is 12) and from admin panel i have assigned this page ID to particular product. For example, Information-id 12 is assigned to to Product1. When a user buys that product, and when the order status is set to 'Complete', user should have access to that page(information-id). I mean , to access this page, user should buy that product and order status is to be complete and user should logged in.
I am not getting how to do it. In order.tpl, i tried doing like this, but if i copy the URL and paste , it can be accessible without logging in.
here is my order_list.tpl
$end_date= date('Y-m-d', strtotime($start_date. ' + '.$date1. 'days'));
echo date('d/m/Y',strtotime($end_date));
?></td>
</tr>
<tr>
<td class="history">Product Name</td>
<?php $today = date('Y-m-d'); ?>
<?php if(($order['status']='Complete') AND ($today > $end_date)) { ?>
<td><strong><h4><font color="#FF0000">Either Your Course date is Expired or Order is not completed!!</font></h4></strong> </td>
<?php }
else { ?>
<td><strong><?php echo $order['pname']; ?></strong></td>
<?php } ?>
</tr>
Here i am also checking the expiry date, which am capturing through admin.
If i put customer_islogged(), in information.php(controller), i cannot access any other pages.

Create a function where you can pass list of products, any of that needs to be purchased to access that particular page
//catalog/model/account/order.php
public function checkForAccess($product_id_list){
$exists = false;
$query = $this->db->query("SELECT product_id FROM ".DB_PREFIX."order o LEFT JOIN ".DB_PREFIX."order_product op ON (o.order_id=op.order_id) WHERE o.order_status_id=5 AND o.customer_id = '" . (int)$this->customer->getId() ."'");
foreach($query->rows as $product){
if(in_array($product['product_id'],$product_id_list)){
$exists = true;
break;
}
}
return $exists;
}
Now in that particular page you can check if the customer has completed purchased or not
$this->load->model('account/order');
//Eg Customer will have access who have purchased product 20 and 22
$product_list = array(20,22);
$results = $this->model_account_order->checkForAccess($product_list);
if(!$results){
//where to redirect if not valid
$this->response->redirect($this->url->link('common/home'));
}
