如何将变量从搜索表单传递给另一个操作

How do I pass variables to another action from a search form?

本文关键字：另一个 操作 表单 搜索表 变量 搜索 | 更新日期: 2023-09-27

我有两个搜索页面。一个是精简搜索表单，另一个是高级搜索。

我希望用户在精简页面上输入他们的搜索，并被重定向到包含高级搜索字段的结果页面。

我目前遇到的两个问题是：

  • 如何重定向？
  • 字段留空时的最佳做法是什么？

目前，我一直在回顾索引以获取前两个搜索字段

精简搜索 

public function indexAction()
{
     $dbAdapter = $this->getServiceLocator()->get('Zend'Db'Adapter'Adapter');
     $form = new HomeSearchForm($dbAdapter);        
     $request = $this->getRequest();   
     if ($request->isPost()) {    
         $homeSearch = new HomeSearch();          
         $form->setInputFilter($homeSearch->getInputFilter());                
         $form->setData($request->getPost());            
         if ($form->isValid()) { 
             $homeSearch->exchangeArray($form->getData());
             if($homeSearch->search_zip == null)
             {
              $homeSearch->search_zip = 'null';
             }
             if($homeSearch->industry_name == null)
             {
              $homeSearch->industry_name = 'null';
             }

           return $this->redirect()->toRoute('home/results',array(
                'zip'=>$homeSearch->search_zip ,
                'industry'=>$homeSearch->industry_name,
           ));
         }
          else {
              echo "Error";
          }           
    }
      return array('form' => $form);
}

结果/高级搜索

public function resultsAction()
{        
     $search_zip      = $this->params()->fromPost('zip');
     $search_industry = $this->params()->fromRoute('industry');
     $search_language      = $this->params()->fromPost('language');
     $search_gender      = $this->params()->fromRoute('gender');
     $search_name      = $this->params()->fromRoute('name');
     echo var_dump($search_zip);
      echo var_dump($search_industry);
      echo var_dump($search_gender);
     echo var_dump($search_name);
     $dbAdapter = $this->getServiceLocator()->get('Zend'Db'Adapter'Adapter'); 
     $proSearch = new SearchQuery($dbAdapter);
     $form = new SearchForm($dbAdapter); 
     $request = $this->getRequest();   
     if ($request->isPost()) {
         echo 'i post';
         $search = new MainSearch();          
         $form->setInputFilter($search->getInputFilter());                
         $form->setData($request->getPost());  
         if ($form->isValid()) { 
             $search->exchangeArray($form->getData());
             if($search->search_zip == null)
             {
              $search->search_zip = 'null';
             }
             if($search->industry_name == null)
             {
              $search->industry_name = 'null';
             }
             if($search->language_name == null)
             {
              $search->language_name = 'null';
             }
             if($search->pro_gender == null)
             {
              $search->pro_gender = 'null';
             }

         return $this->redirect()->toRoute('home/results', array(
            'action'     => 'results',
            'zip'   => $search->search_zip,
            'industry'   => $search->industry_name,
            'language'   => $search->language_name,
            'gender'   => $search->pro_gender,
            'name'   => $search->pro_name,
          )); 
         }  
     }
      return array(
          'form' => $form,
          'pros' => $proSearch->proSearch($search_zip,$search_industry,$search_language,$search_gender,,$search_name),
              );
}

更新

我能够使用我在下面发布的方法进行搜索。 但是我仍然无法在 url 中发布参数（我能够使用此代码获取我想要的 url，但是我在应用过滤器并将字段绑定到表单时遇到问题$this->form->setAttributes(array('method' => 'GET'));

帖子重定向插件不是用来防止用户返回的吗？ 阅读手册后，我不确定如何使用此插件？ 我不确定为什么该段没有使用以下代码进行设置，我过去曾使用过这个。 

'search_zip'=> $this->search_zip

模块配置

            'results' => array(
                'type' => 'segment',
                'options' => array(
                    'route' => 'results[/:search_zip][/:search_industry][/:language][/:gender][/:designation][/:name]',
                    'defaults' => array(
                        'controller' => 'Application'Controller'Index',
                        'action'     => 'results',

结果行动

  public function resultsAction()
    {   
         $dbAdapter = $this->getServiceLocator()->get('Zend'Db'Adapter'Adapter'); 
         $proSearch = new SearchQuery($dbAdapter);
         $request = $this->getRequest();   
         $form = new SearchForm($dbAdapter);  
         if ($request->isPost()) {
             $search = new MainSearch();          
             $form->setInputFilter($search->getInputFilter());                
             $form->setData($request->getPost());  
             if ($form->isValid()) { 
                 $search->exchangeArray($form->getData());
                 $search_zip = $search->search_zip;
                 $search_industry = $search->search_industry;
                 $search_language = $search->search_language;
                 $search_gender = $search->search_gender;
                 $search_designation = $search->search_designation;
                 $search_name = $search->search_name;
             }  
         }
          return array(
              'form' => $form,
              'pros' => $proSearch->proSearch($search_zip,$search_industry,$search_language,$search_gender,$search_designation,$search_name),
                  );
    }

结果视图

//Search Index
 $title = 'Search';
 $this->headTitle($title);
 ?>
 <h1><?php echo $this->escapeHtml($title); ?></h1>
 <?php
    $form->setAttribute('action', $this->url(
     'home/results',
     array(
         'action' => 'results',
         'search_zip'=> $this->search_zip
     )
 ));
 //$form->setAttributes(array('method' => 'GET'));
 $form->prepare();
 echo $this->form()->openTag($form);
 echo $this->formRow($form->get('industry_name'));
 echo $this->formRow($form->get('search_zip'));
 echo '<br>';
 echo $this->formRow($form->get('language_name'));

     <th>Last Name</th>
     <th>Street Address</th>
     <th>Office Number</th>
     <th>City</th>
     <th>State</th>
     <th>Zip</th>
     <th>&nbsp;</th>

 <?php foreach ($pros as $pro) : ?>
 <tr>
     <td><?php echo $this->escapeHtml($pro->pro_first);?></td>
     <td><?php echo $this->escapeHtml($pro->pro_last);?></td>
     <td><?php echo $this->escapeHtml($pro->pro_street_address);?></td> 
     <td><?php echo $this->escapeHtml($pro->pro_office_number);?></td> 
     <td><?php echo $this->escapeHtml($pro->pro_city);?></td> 
     <td><?php echo $this->escapeHtml($pro->pro_state);?></td> 
     <td><?php echo $this->escapeHtml($pro->pro_zip);?></td> 
 <?php endforeach; ?>
 </table>

首先，

我不会重定向...

在您的搜索视图 phtml 中，您可以简单地执行以下操作：

<?php $this->form->setAttribute('action', $this->url('your/results/route'))->prepare();?>

然后，您可以从处理帖子的索引中删除所有代码。我不会使用两个表单类，只使用一个，只在页面上呈现您需要的项目！

echo $this->form()->openTag($form);
    echo $this->formRow($form->get('search_zip'));
    echo $this->formRow($form->get('industry_name'));
    echo $this->formSubmit($form->get('submit'));
 echo $this->form()->closeTag();

如果用户未在字段中输入任何内容，只需将其留空即可

****更新*****

如果您确实想要使用分段路由，则可以在路由中将这些部分设置为可选

'options'   => array(
                'route'    => '[/:language]',
 )

在没有看到您的路由的情况下很难向您展示，但这应该有效。

见 http://framework.zend.com/manual/2.0/en/modules/zend.mvc.routing.html#zend-mvc-router-http-segment

我已经重构了您提供的代码以显示我将如何处理这个问题。

仔细研究该方法;关键的变化是封装功能。

先决条件

  • 这两种形式都应POST resultsAction()
  • 您只需要一种搜索对象"类型"（此处称为Search）
  • 封装！这两种形式都提供结果和搜索，如果您在逻辑上分离功能，它将使您的代码更容易（阅读和维护）

没有测试，那是你的工作！

public function simpleSearchAction()
{
    $form = $this->getSimpleSearchForm();
    return new ViewModel(compact('form'));
}
public function advancedSearchAction()
{
    $form = $this->getAdvancedSearch();
    return new ViewModel(compact('form'));
}
public function resultsAction()
{
    $request = $this->getRequest();
    $form = $this->getAdvancedSearch();
    $results = array();
    if ($request->isPost()) {
        $form->setData($request->getPost());
        if ($form->isValid()) {
            $search = new Search();
            $search->exchangeArray($form->getData());
            // Execute the search and return the results
            $results = $this->search($search);
            // Populate the form with the search data
            $form->bind($search);
        }
    }
    return new ViewModel(array(
        'form'    => $form,
        'results' => $results,
    ));
}
protected function search(Search $search)
{
    // do search here, although this shouldn't be
    // in the controller, rather a service!
    return $yourResults;
}
// This should be injected into the controller
protected function getAdapter();
// Forms should be using the FormElementManager, not
// being created using new
protected function getSimpleSearchForm();
// Same as above
protected function getAdvancedSearch();

要考虑

  • 发布重定向插件（如果您想要带有搜索词的漂亮URL）
  • 依赖注入！您错过了 ZF2 的好处，在服务工厂中创建DbAdapter和Forms，并将它们注入控制器的构造函数中。
  • 服务层 - 移出search代码将使其可重用，并将控制器逻辑与业务逻辑分开。
