【问题描述】:
假设我有一个带有“帖子”模块的博客。
现在我显示这样的帖子:post/index?id=1
在索引操作中,我生成了一个新的 CommentForm 并将其作为 $this->form 传递给模板,它显示在帖子的底部(它只是一个文本字段,没什么特别的)。表单操作设置为“发布/添加评论”。如何在此表单中显示验证错误?使用 setTemplate('index') 不起作用,因为我必须将 id=1 传递给它...
谢谢
更新:
这是一个示例代码:
public function executeIndex(sfWebRequest $request)
{
$post = Doctrine::getTable('Posts')->find($request->getParameter('id'));
$this->post = $post->getContent();
$comments = $post->getComment();
if ($comments->count() > 0)
$this->comments = $comments;
$this->form = new CommentForm();
$this->form->setDefault('pid', $post->getPrimaryKey());
}
public function executeAddComment(sfWebRequest $request) {
$this->form = new CommentForm();
if ($request->isMethod('post') && $request->hasParameter('comment')) {
$this->form->bind($request->getParameter('comment'));
if ($this->form->isValid()) {
$comment = new Comment();
$comment->setPostId($this->form->getValue('pid'));
$comment->setComment($this->form->getValue('comment'));
$comment->save();
$this->redirect('show/index?id='.$comment->getPostId());
}
}
}
和我的评论表:
class CommentForm extends BaseForm {
public function configure() {
$this->setWidgets(array(
'comment' => new sfWidgetFormTextarea(),
'pid' => new sfWidgetFormInputHidden()
));
$this->widgetSchema->setNameFormat('comment[%s]');
$this->setValidators(array(
'comment' => new sfValidatorString(
array(
'required' => true,
'min_length' => 5
),
array(
'required' => 'The comment field is required.',
'min_length' => 'The message "%value%" is too short. It must be of %min_length% characters at least.'
)),
'pid' => new sfValidatorNumber(
array(
'required' => true,
'min' => 1,
'max' => 4294967295
),
array(
'required' => 'Some fields are missing.'
))
));
}
}
最后是 indexSuccess:
<?php echo $post; ?>
//show comments (skipped)
<h3>Add a comment</h3>
<form action="<?php echo url_for('show/addComment') ?>" method="POST">
<table>
<?php echo $form ?>
<tr>
<td colspan="2">
<input type="submit" />
</td>
</tr>
</table>
</form>
就是这样。
