我目前正在使用Phalcon框架进行项目，该框架具有复杂形式和大量输入的页面，可以很好地分解我将表单分成一个循序渐进的过程
如何在进入下一步之前验证每一步的表格，然后将整个表格保存到最后一步？
我似乎无法找到关于此类流程的任何记录，因为如果我使用表单构建器，它就会完整地验证表单。

简单，只需在表单类中创建一个自定义方法来验证任何步骤，并将来自某个步骤的已发布数据保存到消息类中，并通过＆＃34; stepX＆＃34;将其存储到会话中，当发布的数据不是有效只是从post设置默认值。有效时将其保存到会话中，如上所述。
例如我的意思＆＃34; controller＆＃34;
<?php
class MyController extends BaseController {
public function processStep1Action(){
$form = new MyForm();
if($this->request->isPost()){//im using my custom request class
if(!$form->isValid($this->request->getPost()){
//error messages goes here
$form->setDefaultsFromRequest($this->request); // it will set the filled data
}
else {
$messageClass = new MyMessageContainer();
$messageClass->setData($this->request);//inside parse requested data into message class, or parse it as $messageClass->name = $this->request->getPost('name');
$this->session->save('step1',$messageClass); //maybe it would be want to serialize it
//then redirect to the step 2 or x
}
}
}
}
因此，在下一步中，您可以访问会话中的数据$ this-＆gt; session-＆gt; get（＆＃39; step1＆＃39;）;因此，您可以在最后一步加载所有发布的数据并将其存储到数据库中。
我希望这有帮助！ ：）
这是我的表格，也许对你有帮助。

除了卡米尔的答案之外，另一个需要考虑的选择是在前端使用Javascript来处理您的多步骤表单。这将增加一些复杂性，因为您需要使用javascript来处理表单步骤并进行初步验证，但它只需要一个提交，您可以在单个方法中验证内容。
