Zend_Form元素呈現錯誤順序

Question

在向我的表單添加元素後，我按照奇怪的順序渲染它們，在一個複選框之前獲取提交按鈕。將欣賞提示在哪裏檢查快速修復。

class SomeForm extends My_Form { 
    public function init() { 
     $this->addElements(); 
     //add a few elements (#1) 

     $this->addElements($otherForm->getElements()); 
     //borrow some elements from another form (#2) 

     if ($trueCondition=true) { 
      $this->addElements(); 
      //add one more element which will render at end of form (#3) 
     } 

     $this->addElements(); 
     //some more, including submit button (#4) 

     parent::init(); 
     //call My_Form to register custom decorator; culprit? 
    } 
} 

輸出：

<inputs from addElements() #1 /> 
<inputs from addElements() #2 /> 
<inputs from addElements() #4 /> <- 
<inputs from addElements() #3 /> <- mixed up order 

所有其他形式使用定製的裝飾呈現在他們的添加順序的元素。我沒有發佈裝飾器，因爲它很雜亂。希望這個錯誤在別處。

我嘗試使用此代碼來重現您的問題： -

$formA = new Zend_Form(); 
$formB = new Zend_Form(); 
$formA->addElement(new Zend_Form_Element_Text('formA_text1')); 
$formA->addElement(new Zend_Form_Element_Text('formA_text2')); 
$formB->addElement(new Zend_Form_Element_Text('formB_text1')); 
$formB->addElement(new Zend_Form_Element_Text('formB_text2')); 

$formA->addElements($formB->getElements()); 
$formA->addElement(new Zend_Form_Element_Text('formA_text3')); 
$formA->addElement(new Zend_Form_Element_Submit('submit')); 
echo $formA->render(); 

這給了我這個輸出（裝飾刪除）

<input type="text" name="formA_text1" id="formA_text1" value=""> 
<input type="text" name="formA_text2" id="formA_text2" value=""> 
<input type="text" name="formB_text1" id="formB_text1" value=""> 
<input type="text" name="formB_text2" id="formB_text2" value=""> 
<input type="text" name="formA_text3" id="formA_text3" value=""> 
<input type="submit" name="submit" id="submit" value="submit"> 

這是你期待什麼。重現你的問題的唯一途徑是通過設置元素的順序$formB

$formA = new Zend_Form(); 
$formB = new Zend_Form(); 
$formA->addElement(new Zend_Form_Element_Text('formA_text1')); 
$formA->addElement(new Zend_Form_Element_Text('formA_text2')); 
$formB->addElement(new Zend_Form_Element_Text('formB_text1')); 
$formB->addElement(new Zend_Form_Element_Text('formB_text2')); 
$formB->getElement('formB_text2')->setOrder(10); 
$formA->addElements($formB->getElements()); 
$formA->addElement(new Zend_Form_Element_Text('formA_text3')); 
$formA->addElement(new Zend_Form_Element_Submit('submit')); 
echo $formA->render(); 

這給了我這個輸出

<input type="text" name="formA_text1" id="formA_text1" value=""> 
<input type="text" name="formA_text2" id="formA_text2" value=""> 
<input type="text" name="formB_text1" id="formB_text1" value=""> 
<input type="text" name="formA_text3" id="formA_text3" value=""> 
<input type="submit" name="submit" id="submit" value="submit"> 
<input type="text" name="formB_text2" id="formB_text2" value=""> 

這是你做了什麼。所以，在我看來，你必須設置$otherForm中元素的順序。
