magento accesing "SendFriend" module from category page - magento

Question

I'm trying to add the "send to a friend" action to a category page.
In the product view i can see this code:
"canEmailToFriend()): ?>
<p class="email-friend"><?php echo $this->__('Email to a Friend') ?></p>
<?php endif; ?>
If I try to add this code to my "list.phtml" (where products grid is displayed) I receive this error:
Invalid method Mage_Catalog_Block_Product_List::canEmailToFriend(Array
saying that this methos is not available in this context...
Who can I add the funcionality of "sendtofriend" module to any page I need?
Thanks in advance

Answer 1

This is because the $this->canEmailToFriend() call is a block method belonging to the product page, a class called Mage_Catalog_Block_Product_View. The product listing page uses a block class called Mage_Catalog_Block_Product_List which does not include this code.
The method canEmailToFriend() contains (as defined in app/code/core/Mage/Catalog/Block/Product/View.php) the logic:
$sendToFriendModel = Mage::registry('send_to_friend_model');
return $sendToFriendModel && $sendToFriendModel->canEmailToFriend();
You could embed that directly in your template and then call the helper to output the link if $sendToFriendModel->canEmailToFriend(), but the best way to achieve this would be to move the canEmailToFriend functionality out into a new helper and call it from there.

I founded an alternative solution, just load sendfriend model
$sendToFriendModel = Mage::getModel('sendfriend/sendfriend');
Then use
<?php if ( $sendToFriendModel->canEmailToFriend() ) : ?>
<p class="email-friend"><span><span><?php echo $this->__('Email to a Friend') ?></span></span></p>
<?php endif;?>

I think Mage::registry('send_to_friend_model') returns an object of the class Mage_Sendfriend_Model_Sendfriend. The canEmailToFriend() method in Mage_Sendfriend_Model_Sendfriend checks whether the "email to a friend" functionality is enabled:
You can find these two methods in app/code/core/Mage/Sendfriend/Model/Sendfriend.php:
/**
* Check if user is allowed to email product to a friend
*
* #return boolean
*/
public function canEmailToFriend()
{
return $this->_getHelper()->isEnabled();
}
/**
* Retrieve Data Helper
*
* #return Mage_Sendfriend_Helper_Data
*/
protected function _getHelper()
{
return Mage::helper('sendfriend');
}
So you could check that yourself in your template like so:
<?php if (Mage::helper('sendfriend')->isEnabled()) : ?>
<?php // Do stuff ?>
<?php endif ?>
