Php 基于条件的Zend表单元素

我遇到了一个需要显示不同表单元素的问题

• 根据用户的不同情况，我知道在核心php中很容易做到，但我希望在zend环境中做到这一点

示例：

如果此人被禁用，我们将显示两个单选按钮

$disable = new Shaadi_Form_Element_radio('disablitiy');
$disableArr = array(""=>" Doesn't Matter","Y"=>" show disabled");

$disable = new Shaadi_Form_Element_radio('disablitiy');
$disableArr = array(""=>" Doesn't Matter","N"=>" do not show disabled");

如果他没有残疾

$disable = new Shaadi_Form_Element_radio('disablitiy');
$disableArr = array(""=>" Doesn't Matter","Y"=>" show disabled");

$disable = new Shaadi_Form_Element_radio('disablitiy');
$disableArr = array(""=>" Doesn't Matter","N"=>" do not show disabled");

我希望此代码以表单的形式完成如何优化此代码请帮助我

每当表单或任何对象依赖于表单外部的某些信息时，我通常在表单的构造函数中传递这些信息。然后，当我构建表单时，我将稍后在

init（）

中检查它

例如：

class My_Form extends Zend_Form
{
    protected $hasDisability;

    public function __construct($hasDisability)
    {
        $this->hasDisability = (bool) $hasDisability;
        parent::__construct();
    }

    public function init()
    {
        // Add all your other elements
        // Blah, blah

        // Add the element that is dependent upon the $hasDisability value
        $disable = new Shaadi_Form_Element_radio('disablitiy');
        $disableArr = $this->hasDisability
            ? array(""=>" Doesn't Matter","Y"=>" show disabled")
            : array(""=>" Doesn't Matter","N"=>" do not show disabled");

        // Add the $disableArr into the radio element
        $disable->setMultiOptions($disableArr); 
    }
}

用法-可能在控制器中-类似于：

$form = new My_Form(true);  // for a disabled used
$form = new My_Form(false);  // for a non-disabled user

要在表单中实现元素，根据某些条件，需要通过控制器传递表单构造函数中的用户禁用选项。 您可以执行以下步骤在视图中显示单选按钮：

表格编号：

 class Application_Form_User extends Zend_Form {
        public function init() {
            $formAttribs = $this->getAttribs();
            $isDisable   = $formAttribs['disable'];

            if (!$disabled) {
               $disableArr = array(""=>" Doesn't Matter","Y"=>" show disabled");
            } else {
              $disableArr = array(""=>" Doesn't Matter","N"=>" do not show disabled");
            }

            $this->addElement('radio', 'disability', array(
                              'label' => 'Disability',
                              'required' => true,
                              'multiOptions' => $disableArr,                
            ));

        }
    }

In controller:

    public function addAction() {
        $disable = ($user->disable) ? true : false;
        $form = new Application_Form_User(array('disable' => $disable));
        $this->view->form = $form;
    }

在视图中，您可以获得如下“残疾”元素：

  <?php echo $this->form->getelement('disability'); ?>

---

在表单中，定义您的无线电元素：

$disable = new Shaadi_Form_Element_radio('disablitiy');

在控制器中，调用此元素并添加好的选项：

if ($disable)
    $disableArr = array(""=>" Doesn't Matter","Y"=>" show disabled");
else
    $disableArr = array(""=>" Doesn't Matter","N"=>" do not show disabled");

$form->getElement('disablitiy')->setMultiOptions($disableArr);
