Zend_From問題。 無法設置屬性，包括方法

[英]Problem with Zend_From. Not able to set Attribs, including Method

問題描述

我在添加方法和操作以及使其顯示時遇到一些困難。

我正在創建一個表單，然后從數據庫中獲取一些應該進入表單的字段信息，然后將它們添加到表單中，然后進行渲染。 由於沒有方法或動作，因此一切都可以完美完成，直到我要提交表單為止。

這是代碼var_dump和生成的HTML： 

 public function getForm($id) {
      $ar= $this->formElementModel->getElements($id);
      //print_r($ar);
      $form= new Zend_Form();

      $form->setAction('/resource/process')

           ->setMethod('post');

                foreach ($ar as $arr) {
             $form->addElement($this->elementModel->getElement($arr['formElementId'], $this->genRandomString(),false));
            //$fieldArray[] = ;

        }

        $form->addElement('submit', 'submit',array('order'=>100))->setMethod('post');
        var_dump($form);
       // var_dump($fieldArray);
        return $form;
    }

var_dump（）輸出：

以及生成的HTML： 

<form id="fZvN9un1xn4Uh9yZzgWOi9NluFf6CiOuFWH6ugVQSkapm2SV2Jb">

<dd id="textElement40_yu75r8x22i-element">
<input name="textElement40_yu75r8x22i" id="textElement40_yu75r8x22i" value="" type="text"></dd>
<dt id="selectElement39_19voehc8bz-label"><label for="selectElement39_19voehc8bz" class="optional">Dynamic elements</label></dt>
<dd id="selectElement39_19voehc8bz-element">
<select name="selectElement39_19voehc8bz" id="selectElement39_19voehc8bz">
    <option value="sdffdsf" label="Nekāda sudfdfdss s s nebūs! - newText26">Nekāda sudfdfdss s s nebūs! - newText26</option>

    <option value="newName21" label="newTitle22 - newText23">newTitle22 - newText23</option>
</select>
<p class="description">Vienlkāršs elementsa</p></dd>
<dt id="textElement37_wz47pigru9-label"><label for="textElement37_wz47pigru9" class="optional">Nosaukums</label></dt>
<dd id="textElement37_wz47pigru9-element">
<input name="textElement37_wz47pigru9" id="textElement37_wz47pigru9" value="" type="text"></dd>
<dt id="submit-label">&nbsp;</dt><dd id="submit-element">
<input name="submit" id="submit" value="submit" type="submit"></dd></dl></form>

控制器腳本 

    public function viewAction($formId=NULL) {
        $id = $formId;

        if ($formId === NULL) {
            $id = $this->_getParam('id');
        }
        $form=$this->formModel->getForm($id);

        if ($this->getRequest()->isPost()) {
print_r($this->_getAllParams());
        }
        $this->view->fields =$form ->render();
    }

救命？！

[編輯]剛剛發現了一些奇怪的東西。 如果我在Controller內創建一個表單並在其中添加字段，則可以正常顯示。 如果我將Form傳遞給Model和背面，那么方法和動作就不存在了，即使以前也沒有。

我將嘗試在其自己的文件中創建一個新表單，在表單文件中動態添加字段，然后將其取回。 [EDIT2]剛剛發現了其他東西，這很奇怪。 當我直接從控制器回顯表單時，它就可以正常工作。 如果我將其分配給視圖變量，然后在視圖中回顯它，則它將不起作用。

2 個解決方案

嘗試改變 

$this->view->fields =$form ->render();

至 

$this->view->form =$form;

然后在您看來 

echo $this->form

應該將傳遞給表單的render()傳遞為Documented的View，我從未將setView()用於表單，並且它總是可以正常工作。

在Zend_Form對象上調用echo或print()將使用其__toString()方法並輸出其生成的HTML。

希望能有所幫助

問題出在使用JavaScript干擾了該過程。
