how to get current wishlist in magento - php

Question

guys sorry for bad English.
I am using in Magento enterprise I am working in wishlist there is a function in core at path
C:\xampp\htdocs\projects\baab.bh\app\code\core\Mage\Wishlist\Helper\Data.php
getWishlist()
When I am calling this function to get wishlist from front-end phtml file it's giving me correct wishlist but when I am calling this function from controller it's giving me default wishlist only not the current wishlist here is the code of this function
public function getWishlist()
{
if (is_null($this->_wishlist)) {
if (Mage::registry('shared_wishlist')) {
$this->_wishlist = Mage::registry('shared_wishlist');
} elseif (Mage::registry('wishlist')) {
$this->_wishlist = Mage::registry('wishlist');
} else {
$this->_wishlist = Mage::getModel('wishlist/wishlist');
if ($this->getCustomer()) {
$this->_wishlist->loadByCustomer($this->getCustomer());
}
}
}
return $this->_wishlist;
}
I am calling it with the same code but it behaves differently from front-end phtml file and from controller. How can I get current wishlist from the controller as well?

Answer 1

For this, you will get all customers wishlist:
public function getWishlist()
{
$customer = Mage::getModel('customer/customer')->getCollection()->addAttributeToSelect('*');
$wishList = Mage::getModel('wishlist/wishlist')->loadByCustomer($customer);
$wishListAllItem = $wishList->getItemCollection();
if (count($wishListAllItem)) {
$arrOfProductIds = array();
foreach ($wishListAllItem as $item) {
$arrOfProductIds[] = $item->getProductId();
}
}
return $arrOfProductIds;
}
For this, you can get current user wishlist:
$wishList = Mage::getSingleton('wishlist/wishlist')->loadByCustomer($customer)
$wishListAllItem = $wishList->getItemCollection();
if (count($wishListAllItem)) {
$arrOfProductIds = array();
foreach ($wishListAllItem as $item) {
$product = $item->getProduct();
$arrOfProductIds[] = $product->getId();
}
}
