Adding multiple products to wishlist

This is tutorial for guiding create a button adding multiple products to wishlist in category page. Let’s start !
Firstly, We need to create a button. Go to the the file : app/design/frontend/default/your-current-theme/catalog/product/list.phtml

Put this code . Notice my highlighter code

<?php
/**
* Product list template
*
* @see Mage_Catalog_Block_Product_List
*/
?>
<?php
$_productCollection=$this->getLoadedProductCollection();
$_helper = $this->helper('catalog/output');
?>
<?php if(!$_productCollection->count()): ?>
<p class="note-msg"><?php echo $this->__('There are no products matching the selection.') ?></p>
<?php else: ?>
<div class="category-products">

[/code]

Secondly, We also need a controller to handle this action. I recommend you to create a new controller which is extended Mage_Wishlist_IndexController .

In this case, to easy management we create a new module , so we can disable or custom it later.

Create app/etc/modules/Yourcompany_Wishlist.xml for registering new module in magento :

<?xml version="1.0"?>

<config>
<modules>
<Yourcompany_Wishlist>
<active>true</active>
<codePool>local</codePool>
</Yourcompany_Wishlist>
</modules>
</config>

<?xml version="1.0"?>

<Yourcompany_Wishlist>

<codePool>local</codePool>

</Yourcompany_Wishlist>

</modules>

</config>

Create app/code/local/Yourcompany/Wishlist/etc/config.xml

<?xml version="1.0"?>
<config>
<modules>
<Yourcompany_Wishlist>
<version>1.0.0</version>
</Yourcompany_Wishlist>
</modules>

<frontend>
<routers>
<wishlist>
<use>standard</use>
<args>
<modules>
<Yourcompany_Wishlist before="Mage_Wishlist">Yourcompany_Wishlist</Yourcompany_Wishlist>
</modules>
</args>
</wishlist>
</routers>
</frontend>
</config>

<?xml version="1.0"?>

<Yourcompany_Wishlist>

</Yourcompany_Wishlist>

</modules>

<use>standard</use>

<args>

<Yourcompany_Wishlist before="Mage_Wishlist">Yourcompany_Wishlist</Yourcompany_Wishlist>

</modules>

</args>

</wishlist>

</routers>

</frontend>

</config>

Create a controller to handle request adding multiple products to wishlist

<?php
require_once 'Mage/Wishlist/controllers/IndexController.php';

class Yourcompany_Wishlist_IndexController extends Mage_Wishlist_IndexController
{
public function addmultipleAction(){

$wishlist = $this->_getWishlist();
if (!$wishlist) {
return $this->norouteAction();
}

$session = Mage::getSingleton('customer/session');

$products = $this->getRequest()->getParam('wishlist_products');
$products = json_decode($products,true);

if(!is_array($products)){
$this->_redirect('*/');
return ;
}

foreach($products as $productId):

$productId = (int)$productId;

$product = Mage::getModel('catalog/product')->load($productId);

if (!$product->getId() || !$product->isVisibleInCatalog()) continue;

try {
$requestParams = $products;
if ($session->getBeforeWishlistRequest()) {
$requestParams = $session->getBeforeWishlistRequest();
$session->unsBeforeWishlistRequest();
}
$buyRequest = new Varien_Object($requestParams);

$result = $wishlist->addNewItem($product, $buyRequest);
if (is_string($result)) {
Mage::throwException($result);
}
$wishlist->save();

Mage::dispatchEvent(
'wishlist_add_product',
array(
'wishlist'  => $wishlist,
'product'   => $product,
'item'      => $result
)
);

$referer = $session->getBeforeWishlistUrl();
if ($referer) {
$session->setBeforeWishlistUrl(null);
} else {
$referer = $this->_getRefererUrl();
}

/**
*  Set referer to avoid referring to the compare popup window
*/
$session->setAddActionReferer($referer);

Mage::helper('wishlist')->calculate();

$message = $this->__('%1$s has been added to your wishlist. Click <a href="%2$s">here</a> to continue shopping.', $product->getName(), Mage::helper('core')->escapeUrl($referer));
$session->addSuccess($message);
}
catch (Mage_Core_Exception $e) {
$session->addError($this->__('An error occurred while adding item to wishlist: %s', $e->getMessage()));
}
catch (Exception $e) {
$session->addError($this->__('An error occurred while adding item to wishlist.'));
}

endforeach;

$this->_redirect('*', array('wishlist_id' => $wishlist->getId()));

}
}
?>

<?php

require_once 'Mage/Wishlist/controllers/IndexController.php';

class Yourcompany_Wishlist_IndexController extends Mage_Wishlist_IndexController

{

public function addmultipleAction(){

$wishlist = $this->_getWishlist();

if (!$wishlist) {

return $this->norouteAction();

}

$session = Mage::getSingleton('customer/session');

$products = $this->getRequest()->getParam('wishlist_products');

$products = json_decode($products,true);

if(!is_array($products)){

$this->_redirect('*/');

return ;

}

foreach($products as $productId):

$productId = (int)$productId;

$product = Mage::getModel('catalog/product')->load($productId);

if (!$product->getId() || !$product->isVisibleInCatalog()) continue;

try {

$requestParams = $products;

if ($session->getBeforeWishlistRequest()) {

$requestParams = $session->getBeforeWishlistRequest();

$session->unsBeforeWishlistRequest();

}

$buyRequest = new Varien_Object($requestParams);

$result = $wishlist->addNewItem($product, $buyRequest);

if (is_string($result)) {

Mage::throwException($result);

}

$wishlist->save();

Mage::dispatchEvent(

'wishlist_add_product',

array(

'wishlist' => $wishlist,

'product' => $product,

'item' => $result

)

);

$referer = $session->getBeforeWishlistUrl();

if ($referer) {

$session->setBeforeWishlistUrl(null);

} else {

$referer = $this->_getRefererUrl();

}

/**

* Set referer to avoid referring to the compare popup window

$session->setAddActionReferer($referer);

Mage::helper('wishlist')->calculate();

$message = $this->__('%1$s has been added to your wishlist. Click <a href="%2$s">here</a> to continue shopping.', $product->getName(), Mage::helper('core')->escapeUrl($referer));

$session->addSuccess($message);

}

catch (Mage_Core_Exception $e) {

$session->addError($this->__('An error occurred while adding item to wishlist: %s', $e->getMessage()));

}

catch (Exception $e) {

$session->addError($this->__('An error occurred while adding item to wishlist.'));

}

endforeach;

$this->_redirect('*', array('wishlist_id' => $wishlist->getId()));

}

Try to refresh your cache to see this changes. That’s finish. Happy coding!
