對不起我的英文不好檢查返回的記錄是去年的Symfony2
我的問題是,如何檢查,如果返回的記錄是最後一次。
<?php
/**
* @ORM\Entity
* @ORM\Table(name="post")
*/
class Post
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\OneToMany(targetEntity="Comment", mappedBy="post")
*/
protected $comments;
public function __construct()
{
$this->comments = new ArrayCollection();
}
public function addComment(Comment $comments)
{
$this->comments[] = $comments;
return $this;
}
public function removeComment(Comment $comments)
{
$this->comments->removeElement($comments);
}
public function getComments()
{
return $this->comments;
}
}
兼評實體
class Comment {
/**
* @ORM\id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\ManyToOne(targetEntity="Post", inversedBy="comments")
* @ORM\JoinColumn(name="post_id", referencedColumnName="id")
*/
protected $post;
public function setPost(Post $post = null)
{
$this->post = $post;
return $this;
}
public function getPost()
{
return $this->post;
}
}
而且在我的控制器:
use Doctrine\Common\Collections\Criteria;
class PostController
{
public function myAction()
{
$criteria = Criteria::create()
->orderBy(array("id" => Criteria::ASC))
->setFirstResult($offset)
->setMaxResults($limit);
$em = $this->getDoctrine->getManager();
$post = $em->getRepository("Post")->find(1);
$comments = $post->getComments()->matching($criteria);
}
}
評論返回正是我想要的。但是如何檢查返回的評論是否在評論表中最後?
請幫
是由**創建日期**不是一個選項排序? – nifr
