我有一个小论坛,并希望显示最后10答复的。 我的问题:
我从数据库中得到一些重复的条目,因为在一个职位出现有一定的回复。 如何禁用所有重复的职位,只有一个从所有的员额。 我试图说,如果有更多的则1个回信以相同的forum_post_id>只显示最后一个。
我的观点:
<?php foreach ($forum_reply as $item): ?>
<?php $standing = $item->forum_post_id ?>
<div class="col-lg-12 robie" onClick="location.href='<?= site_url('viewtopic/index/' . $item->forum_post_id) ?>'">
<div class="catcenter55 row">
<div class="col-md-3 deta grew">
<?php echo $this->db->where('forum_post_id', $item->forum_post_id)->get('forum_post')->row()->post_head; ?>
</div>
<div class="col-md-2 deta">
<?php $topcat = $this->db->where('forum_post_id', $item->forum_post_id)->get('forum_post')->row()->forum_cat_id ;?>
<?php echo $this->db->where('forum_cats2_id', $topcat)->get('forum_cats2')->row()->forum_name; ?>
</div>
<div class="col-md-2 deta">
<?php echo $this->db->where('forum_post_id', $item->forum_post_id)->get('forum_post')->row()->views; ?>
</div>
<div class="col-md-2 deta">
<div class="likebg2">+<?php echo $this->db->where('forum_post_id', $item->forum_post_id)->get('forum_post')->row()->likes; ?></div>
</div>
<div class="col-md-3 deta">
<?php foreach ($this->db->order_by('timestamp', 'DESC')->get('forum_reply')->result() as $stan): ?>
<?php if($standing == $stan->forum_post_id): ?>
<?php echo $this->db->where('user_id', $stan->user_id)->get('users')->row()->username; ?> | <?php echo $this->db->order_by('timestamp', 'DESC')->where('forum_reply_id', $stan->forum_reply_id)->get('forum_reply')->row()->timestamp; ?>
<?php break; ?>
<?php endif; ?>
<?php endforeach; ?>
</div>
</div>
</div>
<?php endforeach; ?>
我的控制器
public function index() {
$data['forum_reply'] = $this->db->get('forum_reply')->result();
}
我的结果
