Php 是否将分页添加到Magento中的自定义模块？

我正在尝试在自定义模块中添加分页。我在articles.php的Block文件夹下有以下代码

class Compname_Modname_Block_Articles extends Mage_Core_Block_Template
{
    public function __construct()
    {
        parent::__construct();
        $collection = Mage::getModel('articles/articles')->getCollection(); 
        $this->setCollection($collection);
    }
....
....
    public function getTagsList(){  
                $pager = $this->getLayout()->createBlock('page/html_pager', 'custom.pager'); 
                $pager->setAvailableLimit(array(5=>5,10=>10,20=>20,'all'=>'all'));  
                $pager->setCollection($this->getCollection());   
                $this->setChild('pager', $pager);
                $this->getCollection()->load();
                return $this;                
    }
        public function getPagerHtml()
        {
            return $this->getChildHtml('pager');
        }
.........
..........
}

我有在管理员端cms页面有以下代码

 <reference name="content">
            <block type="articles/articles" name="articles.tags"  as="tags.articles" template="articles/tags.phtml" />
   </reference>

getSize（）始终返回

NULL

，因此我无法获取集合值。请就此提供建议，您可以从

Compname\u Modname\u block\u Articles:：getTagsList（）

这就是为什么

<?php  $collection = $this->getTagsList(); 
var_dump($collection->getSize()); // Always return NULL
?>

True，自定义模块的解决方案

<?php
class Test_Featuredsalons_Block_Featuredsalons extends Mage_Core_Block_Template
{

    public function __construct()
    {
        parent::__construct();
        $collection = Mage::getModel('featuredsalons/featuredsalons')->getCollection();
        $this->setCollection($collection);
    }

    protected function _prepareLayout()
    {
        parent::_prepareLayout();

        $pager = $this->getLayout()->createBlock('page/html_pager', 'custom.pager');
        $pager->setCollection($this->getCollection());
        $this->setChild('pager', $pager);
        $this->getCollection()->load();

        return $this;
    }

    public function getPagerHtml()
    {
        return $this->getChildHtml('pager');
    }

    public function getCollection()     
     {            
        $limit        =    10;
        $curr_page    =    1;

        if(Mage::app()->getRequest()->getParam('p'))
        {
            $curr_page    =    Mage::app()->getRequest()->getParam('p');
        }

        //Calculate Offset    
        $offset     =    ($curr_page - 1) * $limit;

        $collection    =    Mage::getModel('featuredsalons/featuredsalons')->getCollection()
                                                    ->addFieldToFilter('status',1);

        $collection->getSelect()->limit($limit,$offset);

        return $collection;
    }    


}
?>

In phtml file, use below code:
<?php     echo $this->getPagerHtml();     ?>    
<?php    $news    =    $this->getCollection();    ?>

在phtml文件中，使用以下代码：

谢谢， 卡西夫

<?php  $collection = $this->getTagsList(); 
var_dump($collection->getSize()); // Always return NULL
?>

<?php
class Test_Featuredsalons_Block_Featuredsalons extends Mage_Core_Block_Template
{

    public function __construct()
    {
        parent::__construct();
        $collection = Mage::getModel('featuredsalons/featuredsalons')->getCollection();
        $this->setCollection($collection);
    }

    protected function _prepareLayout()
    {
        parent::_prepareLayout();

        $pager = $this->getLayout()->createBlock('page/html_pager', 'custom.pager');
        $pager->setCollection($this->getCollection());
        $this->setChild('pager', $pager);
        $this->getCollection()->load();

        return $this;
    }

    public function getPagerHtml()
    {
        return $this->getChildHtml('pager');
    }

    public function getCollection()     
     {            
        $limit        =    10;
        $curr_page    =    1;

        if(Mage::app()->getRequest()->getParam('p'))
        {
            $curr_page    =    Mage::app()->getRequest()->getParam('p');
        }

        //Calculate Offset    
        $offset     =    ($curr_page - 1) * $limit;

        $collection    =    Mage::getModel('featuredsalons/featuredsalons')->getCollection()
                                                    ->addFieldToFilter('status',1);

        $collection->getSelect()->limit($limit,$offset);

        return $collection;
    }

?>

In phtml file, use below code:
<?php     echo $this->getPagerHtml();     ?>    
<?php    $news    =    $this->getCollection();    ?>
