Zend_Form的不能在循環

Question

創建元素就像在話題我嘗試創建一個表單時的元素在循環創建：

foreach($aQuestionList as $aQuestionValue){ 

     $aAnswerList = $oAnswerList->getListByQuestionId($aQuestionValue['newsletter_question_id']); 

     $oNote = new SilverCms_Core_Form_Element_Note('note',array('value'=>'<p>'.$aQuestionValue['newsletter_question_name'].'</p>')); 
     $this->addElement($oNote); 

     foreach($aAnswerList as $aAnswerValue){ 
      $oCheckBox = new Zend_Form_Element_Checkbox('answer'); 
      $oCheckBox->setLabel($aAnswerValue['newsletter_question_answer_name']); 
      $oCheckBox->isArray(true); 
      $oCheckBox->setCheckedValue($aAnswerValue['newsletter_question_answer_id']); 
      $this->addElement($oCheckBox); 
     } 
    } 

但是，當我whant顯示在視圖的形式

<?php echo $this->filterform;?> 

它的顯示屏只有數組aQuestionList和同樣的情況在最後一個元素是在第二循環 問候

Answer 1

您正在使用相同的名稱（「答案」）每個答案複選框，這樣每個將覆蓋前一個。我想你其實想要Multicheckbox表格元素：

$answer = new Zend_Form_Element_MultiCheckbox('answer'); 
foreach($aAnswerList as $aAnswerValue){ 
    $answer->addMultiOption($aAnswerValue['newsletter_question_answer_id'], $aAnswerValue['newsletter_question_answer_name']); 
} 
$this->addElement($answer); 

這會給你一個複選框和每個選項的標籤。
