Question

编辑：好的，我已将其剥离到最低限度。

以下代码是我如何设置我想要在直接的html / php中完成的。

如果表单已提交且字段验证未通过，则会显示一个文本字段，否则，如果表单尚未提交，则会提供下拉列表。

的HTML / PHP：

<form method="post" action="">
  <div class="state">
      <?php
          if(!$_POST['submit']){
              // show the select list of states.
              echo '<select name="state">
                      <option>list of all states</option>
                    </select>';
          }else{
              // show text input box
              echo '<input type="text" value="'.$_POST['select'].'" name="state" />';
          }
      ?>
  </div>
  <input type="submit" name="submit" value="submit" />

但我不知道如何使用ZendFramework Forms Class进行设置，或者如何利用它来开始这样做。

如果你正在使用Zend Framework，你真的不应该做这种事情（我的意思是写纯文本形式）。您应该使用内置方法。

首先，启用表单并创建表单。然后使用这个非常容易理解的代码。请注意，如果它100％工作，我没试过，但这是你需要的逻辑的100％。

表单类

class Application_Form_YourFormName extends Zend_Form
{
   public function init()
   {

      $this->setMethod(self::METHOD_POST);
      $this->setAction('THE-URL-WHERE-THIS-FORM-IS-MANAGED');

      $Element = new Zend_Form_Element_Text('state');
      $Element->setLabel('State:');
      $Element->addValidators(array(/*DON'T KNOW WHAT KIND OF VALIDATION YOU NEED*/));
      $Element->addFilters(array(new Zend_Filter_StringTrim(),
          new Zend_Filter_HtmlEntities(array('quotestyle' => ENT_QUOTES))));
      $Element->setRequired();
      $this->addElement($Element);
      unset($Element);

      $this->addElement('reset', 'Reset');
      $this->addElement('submit', 'Submit');
   }

   public function stateNotPresent()
   {
      $this->removeElement('state');

      // Note that getStates() is an hypotetical method of an
      // hypotetical Application_Model_State where you can retrieve an
      // array containing the list of the state you have. This array is
      // needed to fill the Select list.
      $States = Application_Model_State::getStates();
      $Element = new Zend_Form_Element_Select('statelist');
      $Element->setLabel('State:');
      $Element->setMultiOptions($States);
      $Element->addValidator(new Zend_Validate_InArray($States));
      $Element->setRequired();
      $Element->setOrder($this->count() - 2);
      $this->addElement($Element);
      unset($Element);
   }

}

控制器类

public function name-of-the-action-you-needAction()
{
   $Form = new Application_Form_YourFormName();
   if ($this->_request->isPost())
   {
      if ($Form->isValid($this->_request->getPost()))
      {
         // Do things. A good text has been entered
      }
      else
      {
         $Form->stateNotPresent();
         if ($Form->isValid($this->_request->getPost()))
         {
            // Do things. A good selection has been entered.
         }
         else
         {
            // echo the edited form (the one with the dropdown list)
            $this->view->Form = $Form;
         }      
      }
   }
   // The first time the page is requested.
   // The page with the text box will be printed
   else
      $this->view->Form = $Form;
}

查看-OF-THE-ACTION.phtml

if ($this->Form != null) echo $this->Form;

我希望你能理解我为让你理解所做的努力。
