如何將$ _GET與paginator一起使用？

Question

我通過select-> order by $ GET-variables在我的項目中添加了排序數據。但是，當我通過paginator瀏覽頁面時，當然這些變量不會傳遞到下一頁。傳遞這個變量並將其與paginator一起使用的最佳方式是什麼？

控制器：

public function indexAction() 
{ 
    $sortForm = new \Records\Form\SortingForm(); 
    $field = 'date'; 
    $order = 'desc'; 
    $request = $this->getRequest(); 

    if ($request->isGet()){ 
     $sortForm->setValidationGroup(array('field', 'order')); 
     $sortData = $request->getQuery()->toArray(); 
     $sortForm->setData($sortData); 

     if($sortForm->isValid()) { 
      $sortForm->getData($sortData); 
      $field = (string) $this->params()->fromQuery('field', 'date'); 
      $order = (string) $this->params()->fromQuery('order', 'desc'); 
     } 
    } 
    $query = $this->getRecordsTable()->fetchAll($field, $order); 

    $paginator = new Paginator\Paginator(new Paginator\Adapter\Iterator($query)); 
    $paginator->setCurrentPageNumber($this->params()->fromRoute('page', 1)); 
    $paginator->setItemCountPerPage(25); 

    $vm = new ViewModel(array('records' => $paginator)); 

型號：

public function fetchAll($field, $order) 
    { 
     $this->field = $field; 
     $this->order = $order; 
     $resultSet = $this->tableGateway->select(function (Select $select) { 
     $select->columns(array('date', 'name', 'email', 'homepage', 'text', 'image', 'file')); 
     $select->order($this->field.' '.$this->order);   
     }); 
     $resultSet->buffer(); 
     $resultSet->next(); 

     return $resultSet; 
    } 

形式：

public function __construct($name = null) 
    { 
     parent::__construct('records'); 
     $this->setAttribute('method', 'get'); 

     $this->add(array(
      'name' => 'field', 
      'required' => false, 
      'type' => 'Zend\Form\Element\Select', 
      'options' => array(
       'label' => 'Sort by: ', 
       'value_options' => array(
        'date' => 'Date', 
        'email' => 'E-mail', 
        'name' => 'Username', 
      ), 
     ))); 
     $this->add(array(
      'name' => 'order', 
      'required' => false, 
      'type' => 'Zend\Form\Element\Select', 
      'options' => array(
       'value_options' => array(
        'asc' => 'ascending', 
        'desc' => 'descending', 
      ), 
     ))); 
     $this->add(array(
      'name' => 'submit', 
      'attributes' => array(
       'type' => 'submit', 
       'value' => 'Go', 
       'id' => 'submitbutton', 
      ), 
     )); 
    } 

分頁程序視圖：

<!-- Numbered page links --> 
<?php foreach ($this->pagesInRange as $page): ?> 
    <?php if ($page != $this->current): ?> 
    <a href="<?php echo $this->url($this->route, array('page' => $page)); ?>"> 
     <?php echo $page; ?> 
    </a> | 
    <?php else: ?> 
    <?php echo $page; ?> | 
    <?php endif; ?> 
<?php endforeach; ?> 

另一個：當我傳遞get變量時，查詢字符串看起來像http://guest-book.me/page/7?field=date&order=asc& submit =去我怎麼能不發送pair submit =>值？

謝謝你的幫忙！ :)

首先，你需要確保你使用的分頁程序的路徑有一個查詢字符串的孩子的路線，我會建議有一個路線專門爲使用與分頁列表，一個例子：

'router' => array(
    'routes' => array(
     'paginator_route' => array(
      'type' => 'segment', 
      'options' => array(
       'route' => '/list/:controller/:action[/page/:page][/]', 
       'constraints' => array(
        //'__NAMESPACE__' => 'Application\Controller', 
        'controller' => '[a-zA-Z][a-zA-Z0-9_-]*', 
        'page'   => '[0-9]+', 
       ), 
       'defaults' => array(
        'controller' => 'index', 
        'action'  => 'list', 
        'page'  => 1, 
       ), 
      ), 
      'may_terminate' => true, // with or without Query string 
      'child_routes' => array(
       'query' => array(// allows us to match query string 
        'type' => 'Query', 
        'options' => array(
         'defaults' => array(
          // Query string defaults here.. 
         ) 
        ) 
       ), 
      ), 
     ), 

現在，您需要修改分頁視圖，使我們能夠生成新的鏈接時，使用電流的參數作爲基礎：

<!-- Numbered page links --> 
<?php foreach ($this->pagesInRange as $page): ?> 
    <?php if ($page != $this->current): ?> 
    <?php // the last param allows us to reuse the matched params ?> 
    <a href="<?php echo $this->url($this->route, array('page' => $page), TRUE); ?>"> 
     <?php echo $page; ?> 
    </a> | 
    <?php else: ?> 
    <?php echo $page; ?> | 
    <?php endif; ?> 
<?php endforeach; ?> 

分頁鏈接現在應該保留查詢字符串值:-)

您可以創建一個幫助器，將GET參數傳遞給url。我爲此創建了一個示例模塊：https://github.com/samsonasik/SanSamplePagination
