Magneto get Previous & Next Product Links on Product view Page

It will be easy if you will get the next and previous product from any page instead of going to category or navigation or any other link You can add this code in any of the temaplte file Suppose we are showing in the view.phtml

<?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) );
}
?>
