Question

EDIT: Okay,我把这 stripped倒到最低限度。

下面的法典是我如何确定我试图在直截了当的html/php中实现的目标。

如果提交表格,对田地的核查没有通过,则案文领域出现,否则,如果提交NOT表格,则提供下降。

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" />

但是,我不知道我如何与ZendFramework表格类别建立这种关系,也不知道如何利用它来这样做。

You really should not do this kind of stuff (I mean write plain-text form) if you re using Zend Framework. You should use the built-in methods.

首先,使表格能够形成并形成形式。然后使用这一非常易懂的代码。请注意,如果我的工作达到100%,我不会受到审判,但这是你需要的100%逻辑。

Form class

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);
   }

}

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;
}

VIEW-OF-THE-ACTION.phtml>

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

I hope you ll appreciate the effort I made to let you understand.
