Zend_Paginator如何根据变量查询的交换工作?
第8行执行单次提取,即使更改查询变量也不会更改。
如何根据gdata feed的start-index进行分页功能?
代码:http://pastebin.com/rmxSP1Us
$yt = new Zend_Gdata_YouTube();
$limit = 12;
$offset = ($page - 1) * $limit + 1;
$query = "http://gdata.youtube.com/feeds/api/users/aculinario/favorites?start-index=$offset";
$paginator = Zend_Paginator::factory($yt->getVideoFeed($query));
$paginator->setCurrentPageNumber($page);
$paginator->setItemCountPerPage($limit);
$paginator->setPageRange(6);
$this->view->paginator = $paginator;
echo $query // query changes but paginator no, every time Zend_Paginator factory should check the returned array of getVideoFeed, but not this checking

我有类似的工作使用快速&脏的paginator适配器。
值得注意的是,可能有更好,更通用的方法来实现这一目标。但如果你赶时间,这将让你前进。
<?php
class Lib_Paginator_Adapter_YoutubeUser implements Zend_Paginator_Adapter_Interface
{
protected $_username;
protected $_results;
public function __construct($username)
{
$this->_username = $username;
}
public function getItems($offset, $itemCountPerPage)
{
$url = sprintf(
'%s/%s/%s',
Zend_Gdata_YouTube::USER_URI,
$this->_username,
Zend_Gdata_YouTube::UPLOADS_URI_SUFFIX
);
try
{
$query = new Zend_Gdata_Query($url);
$query->setMaxResults($itemCountPerPage)
->setStartIndex($offset);
$youtube = new Zend_Gdata_YouTube();
$this->_results = $youtube->getUserUploads(null, $query);
return $this->_results;
}
catch (Exception $ex)
{
echo $ex->getMessage();
exit;
}
}
public function count()
{
try
{
$youtube = new Zend_Gdata_YouTube();
return $youtube->getUserUploads($this->_username)->getTotalResults()->getText();
}
catch (Exception $ex)
{
echo $ex->getMessage();
exit;
}
}
}
然后在您的控制器中
$page = $this->getRequest()->getParam("page");
$limit = 10;
$username = 'aculinario';
$paginator = new Zend_Paginator(new Lib_Paginator_Adapter_YoutubeUser($username));
$paginator->setItemCountPerPage($limit);
$paginator->setPageRange(10);
$paginator->setCurrentPageNumber($page);
$this->view->youtubeFeed = $paginator;
