如何保存包含学说嵌入表单的sfForm - How to save an sfForm which contains doctrine embedded forms?

我有一个基于KanoonGood模型类的条令形式（Kanoon古德形式），它看起来像这样：

class KanoonGoodForm extends BaseKanoonGoodForm
{
    public function configure()
    {
       $this->widgetSchema['count_num']->setAttribute('size', '1');
       $this->widgetSchema['price']->setAttribute('size', '1');
       $this->validatorSchema['category_id']->setOption('required', false);
       $this->validatorSchema['owner_id']->setOption('required', false);
       $this->validatorSchema['shop_id']->setOption('required', false);
       $this->validatorSchema['name']->setOption('required', false);
       $this->validatorSchema['price']->setOption('required', false);
       $this->validatorSchema['count_num']->setOption('required', false);
       $this->validatorSchema['description']->setOption('required', false);
    }
}

然后我创建了KanoonGoodsGroupForm类，以拥有一个包含任意数量嵌入Kanoon古德form表单的表单：

class KanoonGoodsGroupForm extends sfForm
{
    public function configure() 
   { 
       for ($i = 0; $i < 2; $i++) 
       {
           $this->embedForm('good_'.($i+1), new KanoonGoodForm());
       }
       $this->widgetSchema->setNameFormat('KanoonGoodsGroup[%s]');
       $this->mergePostValidator(new KanoonGoodValidatorSchema());
   }
}

在一个模块（名为good）中，当调用新操作时，我回显KanoonGoodsGroupForm的一个实例：

public function executeNew(sfWebRequest $request)
{
    $this->form = new KanoonGoodsGroupForm();
}

因为所有嵌入的表格都不需要填写，正如本文所说，我我自己的验证器：

class KAnoonGoodValidatorSchema extends sfValidatorSchema
{
  protected function configure($options = array(), $messages = array())
  {
    $this->addMessage('category_id', 'The category_id is required.');
    $this->addMessage('owner_id', 'The owner_id is required.');
    $this->addMessage('shop_id', 'The shop_id is required.');
    $this->addMessage('name', 'The name is required.');
    $this->addMessage('price', 'The price is required.');
    $this->addMessage('count_num', 'The count_num is required.');
    $this->addMessage('description', 'The description is required.');
  }
  protected function doClean($values)
  {
    $errorSchema = new sfValidatorErrorSchema($this);
    foreach($values as $key => $value)
    {
      $errorSchemaLocal = new sfValidatorErrorSchema($this);
      // no caption and no filename, remove the empty values
      if (!$value['name'] && !$value['price']&& !$value['count_num']&& !$value['description'])
      {
        unset($values[$key]);
      }
      // some error for this embedded-form
      if (count($errorSchemaLocal))
      {
        $errorSchema->addError($errorSchemaLocal, (string) $key);
      }
    }
    // throws the error for the main form
    if (count($errorSchema))
    {
      throw new sfValidatorErrorSchema($this, $errorSchema);
    }
    return $values;
  }
}

现在我想保存那些由用户填写的嵌入表单，我应该在创建操作中做些什么来实现这一点？

public function executeCreate(sfWebRequest $request)
{
    $this->forward404Unless($request->isMethod(sfRequest::POST));
    $this->form = new KanoonGoodsGroupForm();
    $this->form->bind($request->getParameter('KanoonGoodsGroup'), $request->getFiles('KanoonGoodsGroup'));
    if ($this->form->isValid())
    {
         //what should I do here? to save those filled embedded forms?
    }
   $this->setTemplate('edit');
  }

当我遇到类似的问题时，我用表单中的自定义save（）方法解决了它，表单是像这样的嵌入式表单的集合

public function save($conn = null){
    foreach ($this->getEmbeddedForms() as $key => $form) {
        $object = $form->getObject();
        $object->merge($this->getValue($key));
        $object->save($conn);
    }
}

它遍历嵌入的表单，将它们的对象与组表单中经过验证的数据合并，然后将它们保存为

您必须调用：

$this->form->save();

但是，您必须实现与saveEmbeddedForms相关的部分。

您必须实现KanoonGoodsGroupForm的保存方法：

public function save() {
    $this->updateObjectEmbeddedForms($this->getTaintedValues());
    $this->saveEmbeddedForms();
  }
  public function saveEmbeddedForms($forms = null) {
    if (null === $forms) {
      $forms = $this->embeddedForms;
    }
    foreach ($forms as $form) {
      if ($form instanceof sfFormObject) {
        $form->getObject()->save();
        $form->saveEmbeddedForms();
      } else {
        $this->saveEmbeddedForms($form->getEmbeddedForms());
      }
    }
  }

  public function updateObjectEmbeddedForms($values, $forms = null) {
    if (null === $forms) {
      $forms = $this->embeddedForms;
    }
    foreach ($forms as $name => $form) {
      if (!isset($values[$name]) || !is_array($values[$name])) {
        continue;
      }
      if ($form instanceof sfFormObject) {
        $form->updateObject($values[$name]);
      } else {
        $this->updateObjectEmbeddedForms($values[$name], $form->getEmbeddedForms());
      }
    }
  }
