您好，我遇到了 zend 框架的问题。我想用 zend 制作一个多步骤表单，但 zend 不支持，所以我可以将 sub_form 保存在会话变量中并一一验证它们，然后在主表单的末尾获取所有 sub_form 以显示所有表格 ？

在此先感谢您的帮助 ！

这是我的表单代码：

   public function init()
{
    /* Form Elements & Other Definitions Here ... */
    $this->setAttrib("class", "form-horizontal well");

    $name = $this->createElement('text', 'name', array(
                                                        "label" => $this->getTranslator()->translate('ADD_NAME'), 
                                                        "description" => $this->getTranslator()->translate('ADD_EXAMPLE_NAME')
                                                        ))->setRequired(true);

    $trigram = $this->createElement('text', 'trigram', array(
                                                                "label" => $this->getTranslator()->translate('ADD_TRIGRAM'),
                                                                "description" => $this->getTranslator()->translate('ADD_EXAMPLE_TRIGRAM')
                                                                ))->setRequired(true);
    $environment = $this->createElement('select', 'environment', array(
                                                                        "label" => $this->getTranslator()->translate('ADD_ENVIRONMENT')
                                                                        ))->setRequired(true);
    $url_clientsite = $this->createElement('text', 'url_clientsite', array(
                                                                            "label" => $this->getTranslator()->translate('ADD_URL_CLIENT'),
                                                                            "description" => $this->getTranslator()->translate('ADD_EXAMPLE_URL')
                                                                            ))->setRequired(true);

    $check_box = $this->createElement('multicheckbox', 'components', array(
                                                                            "multiOptions" => array(
                                                                                                    "mon" => " BDD Mona",
                                                                                                    "sta" => " BDD Stats",
                                                                                                    "log" => " BDD Logs",
                                                                                                    "sal" => " Sali",
                                                                                                    "agg" => " StatsAggregator",
                                                                                                    "etl" => " ETL",
                                                                                                    "jvs" => " JavaScript",
                                                                                                    "adm" => " Admin"
                                                                                                    )))->setRequired(true);

    $step_1 = new Zend_Form_SubForm();  
    $step_1->addElements(array(
                                $name,
                                $trigram,
                                $environment,
                                $url_clientsite,
                                ));

    $this->addSubForm($step_1, 'step1');

    $step_2 = new Zend_Form_SubForm();
    $step_2->addElement($check_box);
    $this->addSubForm($step_2, 'step2');    

    $step_3 = new Zend_Form_SubForm();
    $step_3->addElements();

    $this->addSubForm($step_3, 'step3');

}
