如何在视图中使用原则查询结果

Question

如何获取独立元素？例如$language->LanguageName .

这是我的控制器代码：

class IndexController extends AbstractActionController {
protected $entityManager;
public function getEntityManager()
{
    if (null === $this->entityManager) {
        $this->entityManager = $this->getServiceLocator()->get('DoctrineORMEntityManager');
    }
    return $this->entityManager;
}
public function indexAction() {
    $language = $this->getEntityManager()
                     ->getRepository('LanguagesModuleEntityLanguageCommon')
                     ->findAll();
    $viewModel = new ViewModel([ 'languages' => $language ]);
    return $viewModel;
}}

这是我的视图文件代码...

<?php foreach ($this->languages as $language) : ?>
<tr>
    <pre><?php print_r($language) ?></pre>
</tr>

结果我有

LanguagesModuleEntityLanguageCommon Object
(
    [LanguageId:protected] => 1
    [LanguageName:protected] => English
    [LanguageCode2:protected] => en
    [LanguageCode3:protected] => eng
    [LanguageImage:protected] => img_path
    [LanguageActive:protected] => 1
)
LanguagesModuleEntityLanguageCommon Object
(
    [LanguageId:protected] => 2
    [LanguageName:protected] => Other
    [LanguageCode2:protected] => ot
    [LanguageCode3:protected] => oth
    [LanguageImage:protected] => image_path
    [LanguageActive:protected] => 1
)

您返回的是一个实体数组。因此，循环访问对象并使用实体的getters来获取每个字段的值。这应该有效：

<?php foreach ($languages as $language) : ?>
            <tr> 
                <td><?php echo $language->getLanguageId(); ?></td>
                <td><?php echo $language->getLanguageName(); ?></td> 
                <td>....</td> 
            </tr>
<?php endforeach;?>
