Question

我在foreach中制作了一个foreach，创建了一个类别div，其中包含与其相关的FAQ问题。现在我想隐藏现有的没有相关常见问题解答的类别。我该怎么做？

查看：

<?php foreach($faqtypetexts as $faqtypetext):?>
  <div class="faqcatdiv">
    <h1><?php echo $faqtypetext['Faqtypetext']['faqtypetext_name']; ?></h1>
    <?php foreach($faqtexts as $faqtext):?>
      <?php if($faqtypetext['Faqtype']['faqtype_id'] == $faqtext['Faq']['faq_rel_faqtype']): ?>
        <section class="faq-section">
          <input type="checkbox" id="q1">
          <label for="q1"><?php echo $faqtext['Faqtext']['faqtext_question']; ?></label>           
          <p>????</p>
          <p><?php echo $faqtext['Faqtext']['faqtext_awnser']; ?></p>   
        </section>
      <?php endif; ?>
    <?php endforeach; ?>
  </div>
<?php endforeach; ?>

控制器功能：

public function faq() {

  // load the website base-layout
  $this->layout = 'website';

  // load relevant models
  $this->loadModel('Faqtext');
  $this->loadModel('Faqtypetext');

  // haal relevante snippets op
  $activelanguage = 2;
  $faqtexts = $this->Faqtext->find('all', array('conditions' => array('Faq.faq_online' => '1', 'Language.language_id' => '2')));
  $faqtypetexts = $this->Faqtypetext->find('all', array('conditions' => array('Language.language_id' => '2')));

  // send snippets to screen
  $this->set('faqtexts', $this->Faqtext->find('all', array('conditions' => array('Faq.faq_online' => '1', 'Language.language_id' => '2'))));
  $this->set('faqtypetexts', $this->Faqtypetext->find('all', array('conditions' => array('Language.language_id' => '2'))));

  // haal relevante contentitems op

  // send content to screen


  // haal nieuws uit de database

  // send to screen

}

Answer 1

三个选项：

Use the counter cache - 最佳解决方案
Use count() on the results - 仅在获取所有类别结果时才会显示
Do a count sub-query - 因性能最差

哦，请处理你的代码格式化风格，这是可怕的来阅读。

为了完成这项工作，我必须使用我需要的信息来压缩我必须使用的数组。我用classicExtract

做了这个

//get all FAQs
$faqs = $this -> Faq -> find('all', array(
    'conditions' => array(
            'Faq.faq_online' => 1               
        )
));
$this->set('faqs', $faqs);
debug($faqs);

//get all faqtexts
$faqtypetexts = $this -> Faqtypetext -> find('all', array(
    'conditions' => array(
        'Faqtypetext.faqtypetext_rel_language' => $activelanguage
    ),  
    'contain' => false
));
$this->set('faqtypetexts', $faqtypetexts);


//make list more compact
$categories = Set::classicExtract($faqtypetexts, '{n}.Faqtypetext.faqtypetext_rel_faqtype');
$this->set('categories', $categories);

对于视图，我创建了一个变量，当循环通过类别时，该变量为空。如果变量为空，则允许回显类别名称，当它再次循环并且变量填充与之前相同的值时，不允许回显类别名称。一旦类别名称的值发生变化，就可以回显类别名称。

<!-- - - - - - - - - - - Repeatable FAQ Div - - - - - - - - - - -->

<?php $lastcategory = ''; ?>  

<!-- - - - - - - - - - - Category Title - - - - - - - - - - -->

    <?php foreach ($faqs as $faq): 

        $faqtypekey = $faq['Faq']['faq_rel_faqtype'];      

        //$categories is result from classicExtract
        $categoryPosition= array_search($faqtypekey, $categories); 

        $categoryRecord = $faqtypetexts[$categoryPosition]; 

        $actualcategory = $categoryRecord['Faqtypetext']['faqtypetext_name']; ?>

        <?php if($actualcategory != $lastcategory){ ?>
            <center>
                <table border="0" width="85%" cellpadding="0" cellspacing="0" >
        <img src="<?php echo FULL_BASE_URL . $this->Html->webroot . 'pics/' . $pixelimage['Image']['image_img']; ?>" height="20" width="1">
            <tr>
            <td bgcolor="#FFFFFF">
                            <div class="categorytitle"><?php echo $actualcategory; ?></div>
                    </td>
                    </tr>
                </table>
            </center>                               
        <?php } ?>

<!-- - - - - - - - - - - FAQ Content - - - - - - - - - - -->

                    <?php $faqtexts = $faq['Faqtext']; ?>

                    <?php foreach ($faqtexts as $faqtext):

                        if ($faqtext['faqtext_rel_language'] == 2) { ?> 

                            <center>
                                <table border="0" width="85%" cellpadding="0" cellspacing="0">
                                    <tr>
                        <td bgcolor="#FFFFFF">
                                            <section class="faq-section" style="margin: 20px 0 0 5px; position:relative;">
                                                <input type="checkbox" id="q1">
                                                    <h4 style="color:#925050;" for="q1"><b><span style="font-weight: lighter;">Q: </span>
                                                    <?php echo $faqtext['faqtext_question']; ?></b></h4>
                                                    <?php echo $faqtext['faqtext_awnser']; ?>                           
                                            </section>
                                        </td>               
                                    </tr>

                        <?php } ?>

                                </table>
                            </center>

<!-- - - - - - - - - - - End of file - - - - - - - - - - -->

                    <?php endforeach;

                $lastcategory = $actualcategory;


    endforeach; ?>

对不起，awnser帖子花了这么长时间，但我不得不将所有div重写成表格。
