Magento - 產品頁面中的上一個和下一個產品鏈接（檢查產品狀態）

Question

我在產品視圖（view.phtml）中實現了「上一個/下一個」按鈕，它工作正常。唯一的問題是，它也試圖顯示產品的狀態：「禁用」。這導致404未找到頁面。

任何解決方法/修復此？
這是我的代碼：

<?php // Previous and Next product links in product page 
$_product = $this->getProduct(); 
if (!$_product->getCategoryIds()) 
    return; // Don't show Previous and Next if product is not in any category 

$cat_ids   = $_product->getCategoryIds(); // get all categories where the product is located 
$cat    = Mage::getModel('catalog/category')->load($cat_ids[0]); // load first category,  you should enhance this, it works for me 
$order    = Mage::getStoreConfig('catalog/frontend/default_sort_by'); 
$direction   = 'asc'; // asc or desc 

$category_products = $cat->getProductCollection()->addAttributeToSort($order, $direction); 
$category_products->addAttributeToFilter('status', 1); // 1 or 2 
$category_products->addAttributeToFilter('visibility', 4); // 1.2.3.4 

$cat_prod_ids = $category_products->getAllIds(); // get all products from the category 
$_product_id = $_product->getId(); 
$_pos   = array_search($_product_id, $cat_prod_ids); // get position of current product 
$_next_pos = $_pos + 1; 
$_prev_pos = $_pos - 1; 

// get the next product url 
if (isset($cat_prod_ids[$_next_pos])) { 
    $_next_prod = Mage::getModel('catalog/product')->load($cat_prod_ids[$_next_pos]); 
} else { 
    $_next_prod = Mage::getModel('catalog/product')->load(reset($cat_prod_ids)); 
} 

// get the previous product url 
if (isset($cat_prod_ids[$_prev_pos])) { 
    $_prev_prod = Mage::getModel('catalog/product')->load($cat_prod_ids[$_prev_pos]); 
} else { 
    $_prev_prod = Mage::getModel('catalog/product')->load(end($cat_prod_ids)); 
} 
?> 

任何幫助，將不勝感激。
謝謝

ENABLE the product。

已禁用的產品無法顯示在前端。
