我需要显示一个表单以在显示新闻故事的同一页面上输入博客文章。用户正在输入与故事相关的博客文章。
在我的博客表单中,我目前正在这样做以获取正在显示的故事的 ID:
public function configure()
{
$this->setWidget('image_filename', new sfWidgetFormInputFileEditable(array(
'file_src' => '/uploads/blogpost_images/thumbnails/thumb_'.$this->getObject()->image_filename, //displayed for existing photos
'edit_mode' => !$this->isNew(),
'is_image' => true,
'with_delete' => false,
)));
$this->setValidator('image_filename', new sfValidatorFile(array(
'mime_types' => 'web_images',
'required' => $this->isNew(),
'path' => sfConfig::get('sf_upload_dir').'/blogpost_images',
'validated_file_class' => 'BlogPostValidatedFile',
)));
$this->setValidator('url', new sfValidatorUrl(array('required' => true)));
$this->setValidator('title', new sfValidatorString(array('required' => true)));
$this->setWidget('user_id', new sfWidgetFormInputHidden(array(),array(
'value'=>sfContext::getInstance()->getUser()->getId())
));
// get the request params to access the notice ID and pass it back to the form for
// saving with the blog post
$params = sfContext::getInstance()->getRequest()->getParameterHolder();
$this->setWidget('notice_id',
new sfWidgetFormInputHidden(array(),array(
'value'=>$params->get('id'))
));
$this->removeFields();
}
有更清洁的方法吗?从请求参数中获取通知(新闻故事)的 id 感觉很奇怪。
更新
我实际上是通过 ajax 从模态对话框中发布表单,并尝试在请求之间维护 notice_id 值。在返回表单以显示错误之前,我将参数与表单绑定:
public function executeModal(sfWebRequest $request) {
if ($request->isXmlHttpRequest()) {
//return $this->renderText('test'.$request->getParameterHolder()->getAll());
$params = $request->getParameter('nb_blog_post');
$form = new nbBlogPostForm(null,array('notice_id',$request->getPostParameter('notice_id')));
$form->bind($params,$request->getFiles());
if ($form->isValid()) {
$nb_blog_post = $form->save();
$this->getUser()->setFlash('notice', 'Your blog post was successfully created');
$this->redirect('@noticeboard');
} else {
return $this->renderPartial('form',array('form'=>$form,'form_id'=>'blogpost'));
}
}
}
我似乎无法让 notice_id 与表单绑定(它是一个隐藏字段)。其他值绑定良好。
I've also tried $form = new nbBlogPostForm(null,array('notice_id',$request->getPostParameter('nb_blog_post[notice_id]')));
进一步更新
在第一次通过表单配置方法时,依赖于请求中的 notice_id,我认为当通过 ajax 再次创建表单时将其设置为 null。这修复了它:
$params = sfContext::getInstance()->getRequest()->getParameterHolder();
if (($params->get('id'))) {
$this->setWidget('notice_id',
new sfWidgetFormInputHidden(array(),array(
'value'=>$params->get('id'))
));
} else {
$this->setWidget('notice_id',
new sfWidgetFormInputHidden());
}
如果有人有更清洁的方法,请告诉我。
