Magento - 在产品列表中添加页码以标题(Magento - Adding page number to title on products listing)

 我有一个扩展，它使用产品列表块通过属性显示产品网格过滤器（扩展名为“ 属性信息页面” ）。 
 
 在该扩展块的“_prepareLayout”函数中，扩展使用以下代码设置页面的标题和描述： 
 
$head = $this->getLayout()->getBlock('head');
.
.
.
$head->setTitle($title);
head->setDescription($des);
 
 我想以这种格式将文本添加到标题和描述中： 
 
$page_info = "Page A of B for ";
$title = $page_info . title;
$items_info = "Listings X-Y (out of Z) ";
$des = items_info . $des;
 
 我试过这段代码，以获得当前页面，最后一页，数字和项目等等： 
 
$html_pager = Mage::getBlockSingleton('page/html_pager');
    $html_pager->setCollection($product_collection);
    $limit = Mage::getSingleton('core/app')->getRequest()->getParam('limit');
    if(empty($limit))
    {
        $limit = 8;
    }

    $html_pager->setLimit($limit);
    $LastPageNumber = $html_pager->getLastPageNum();
    $current_page = $html_pager->getCurrentPage();

    $page_info = "";
    if($current_page > 1)
    {
        $page_info = "Page " . $current_page . " of $LastPageNumber for ";
    }

    $FirstNum = $html_pager->getFirstNum();
    $LastNum = $html_pager->getLastNum();
    $TotalNum = $html_pager->getTotalNum();

    $items_info = "Listings " . $FirstNum . "-" . $LastNum . " (out of ". $TotalNum . ") ";
 
 该代码为我提供了正确的信息，但它在产品网格中导致问题 - 它始终在产品网格中显示10个产品（无论我在“每页显示”中选择什么）。 
 
 任何想法如何在不破坏网格功能的情况下获取信息？ 

I have an extension that uses the products list block to show the products grid filter by an attribute (the extension is Attribute Info Pages).
 
In the "_prepareLayout" function of this extension block the extension sets the page's title and description using this code :
 
$head = $this->getLayout()->getBlock('head');
.
.
.
$head->setTitle($title);
head->setDescription($des);
 
I want to add text to the title and description in this format :
 
$page_info = "Page A of B for ";
$title = $page_info . title;
$items_info = "Listings X-Y (out of Z) ";
$des = items_info . $des;
 
I've tried this code it order to get the current page, last page, number and items and so on :
 
$html_pager = Mage::getBlockSingleton('page/html_pager');
    $html_pager->setCollection($product_collection);
    $limit = Mage::getSingleton('core/app')->getRequest()->getParam('limit');
    if(empty($limit))
    {
        $limit = 8;
    }

    $html_pager->setLimit($limit);
    $LastPageNumber = $html_pager->getLastPageNum();
    $current_page = $html_pager->getCurrentPage();

    $page_info = "";
    if($current_page > 1)
    {
        $page_info = "Page " . $current_page . " of $LastPageNumber for ";
    }

    $FirstNum = $html_pager->getFirstNum();
    $LastNum = $html_pager->getLastNum();
    $TotalNum = $html_pager->getTotalNum();

    $items_info = "Listings " . $FirstNum . "-" . $LastNum . " (out of ". $TotalNum . ") ";
 
The code gives me the correct information but it causes a problem in the products grid - it always shows 10 products in the products grid (no matter what I choose in "Show per page").
 
Any ideas how to get the information without breaking the grid functionality?
