循環訪問Zend_Paginator的對象顯示

Question

我從這個查詢Zend_Paginator_Adapter_DbTableSelect對象：

public function fetchPagedTracks() { 

     $select = $this->select(Zend_Db_Table::SELECT_WITH_FROM_PART) 
         ->setIntegrityCheck(FALSE); 
     $select->join(array('ar' => 'artist'), 'ar.id = track.artist_id', 
       array('artist_name' => 'name')); 
     $select->join(array('al' => 'album'), 'al.id = track.album_id', 
       array('album_name' => 'name', 'artist_id', 'year')); 
     $select->order('artist_name', 'ASC'); 
     $select->order('album_name'); 
     $select->order('track', 'ASC'); 

     //create a new instance of the paginator adapter and return it 
     $adapter = new Zend_Paginator_Adapter_DbTableSelect($select); 

     return $adapter; 
    } 

預期和工程數據的回報，我的問題是我viewscript。我想以特定的方式迭代結果集。基本上我想讓藝術家在每張專輯的子表格的頂部，並列出每首專輯的順序。我已經完成了這個......但不正確，我不得不做我覺得是黑客，我希望能夠幫助我解決它。

這裏是視圖：

<?php 
echo $this->paginationControl(
     $this->paginator, 'Sliding', '_paginatorControl.phtml' 
) 
?> 
<table> 
    <?php 
    foreach ($this->paginator as $track):; 
//  Zend_Debug::dump($track, ''); 
     $artist = $track->artist_name; 
     $album = $track->album_name; 
     ?> 
     <?php if ($end_artist != $artist): ?> 
      <tr> 
       <th colspan="4"><?php echo $track->artist_name ?></th> 
      </tr> 
     <?php endif ?> 
     <?php if ($end_album != $album): ?> 
      <tr> 
       <th colspan="4"><?php echo $track->album_name . ' ' . $track->year ?></th> 
      </tr> 

     <tr> 
      <th>Track #</th> 
      <th>Title</th> 
      <th>Bitrate</th> 
      <th>Play Time</th> 
     </tr> 
     <?php endif; ?> 
     <tr> 
      <td><?php echo $track->track ?></td> 
      <td><?php echo $track->title ?></td> 
      <td><?php echo $track->bit_rate . 'Kbps' ?></td> 
      <td><?php echo $this->playtime($track->play_time) ?></td> 
     </tr> 
     <?php 
     $end_artist = $track->artist_name; 
     $end_album = $track->album_name 
     ?> 

    <?php endforeach ?> 
</table> 
<?php 
echo $this->paginationControl(
     $this->paginator, 'Sliding', '_paginatorControl.phtml' 
); ?> 

最大的問題是，這種代碼會導致兩個公告：

注意：未定義的變量：end_artist在 E：\ WWW \ home.local \程序\模塊\音樂\意見\腳本\首頁\ display.phtml 上線13 ...和第18行

有問題的變量是$end_artist和$end_album對於我來說，我無法弄清楚如何以不同的方式做到這一點。建議？

P.S.該分頁程序對象的轉儲可以在Pastbin

Answer 1

可以看出它似乎$end_artist和$end_album變量之前沒有定義，把

$end_artist = ''; 
$end_album = ''; 

foreach
