我正在使用codeigniter 3.0.3
我在项目中的多个部分面临问题
例如，在我看来，有一个foreach循环来显示帖子
我想在第一个循环中通过post-id做另一个foreach的注释，但我不能因为post_id在foreach循环中的视图中而且我不能传递像
这样的参数$ data ['postcomments'] = $ this-＆gt; model-＆gt; function（$ post_id）;
这是我的观点
<?php if($allposts): ?>
<?php foreach ($allposts as $post): ?>
<div class="panel panel-default">
<div class="panel-body">
<div class="col-md-12 text-muted"><small><?=$post->post_text?></small></div>
<div class="col-md-12 text-muted"><small><?=$post->post_id?></small></div>
</div>
</div>
<?php endforeach; ?>
<?php endif; ?>
可以或如何通过post_id在评论表
中为每篇帖子做评论Comments_table专栏
+-------------+---------+---------+
|commenter_id | comment | post_id |
+-------------+---------+---------+

尝试：
<强>控制器
public function comments() {
$this->load->model('comments_model');
$data["comments"] = $this->comments_model->getAllComments();
$this->load->view("post", $data);
}
<强>模型
public function getAllComments()
{
return $this->db->get("comments_table")->result();
}
查看：
<?php foreach($comments as $post) : ?>
<div class="panel panel-default">
<div class="panel-body">
<div class="col-md-12 text-muted"><small><?php echo $post->comment?></small></div>
<div class="col-md-12 text-muted"><small><?php echo $post->postid?></small></div>
</div>
</div>

这是控制器
$data['postcomments'] = $this->users_model->getAllComments();
我只是将所有评论传递给视图
这是获得所有评论的模型
function getAllComments() {
$this->db->order_by('comment_date DESC');
$this->db->select('*');
$this->db->from('comments_table');
$this->db->join('confirmed_users', 'comments_table.commenter_id = confirmed_users.uid');
$query = $this->db->get();
if($query->num_rows() > 0) {
return $query->result();
} else {
return false;
}
}
这是我的foreach循环显示帖子
<?php if($allposts): ?>
<?php foreach ($allposts as $post): ?>
<div class="panel panel-default">
<div class="panel-body">
<div class="col-md-12" style="padding: 0;">
<img class="img-rounded pull-left" src="<? echo base_url($post->image) ?>" width=30px height=30px>
<div style="margin-top: 5px;">
<a href="<? echo base_url('home?p=Profile&u='.$post->post_author) ?>"><small style="margin-left: 5px;"><?=$post->post_author?></small></a>
<span style="font-size: 75%;" class="text-muted pull-right"><span class="fa fa-clock-o"></span>
<?php $post_date = $post->post_date; $now = time(); $units = 1; ?>
<? echo timespan($post_date, $now, $units) ?>
ago</span>
</div>
</div>
<div class="clear"></div>
<hr class="myown">
<div class="col-md-12 text-muted"><small><?=$post->post_text?></small></div>
<div class="clear"></div>
<hr class="myown">
<div class="btn-group">
<?php if($this->users_model->liked($post->pid)): ?>
<a class="btn btn-default btn-sm disabled"><span class="fa fa-check"></span> Liked</a>
<?php else: ?>
<a class="btn btn-default btn-sm like-btn" post-id="<?=$post->pid?>"><span data-toggle-tooltip="tooltip" data-placement="top" title="Like" class="fa fa-thumbs-up fa-lg"></span></a>
<?php endif; ?>
<a class="btn btn-default btn-sm" data-toggle="collapse" data-target="#<?=$post->pid?>Comment"><span data-toggle-tooltip="tooltip" data-placement="top" title="Comment" class="fa fa-comment fa-lg"></span></a>
<a class="btn btn-default btn-sm"><span data-toggle-tooltip="tooltip" data-placement="top" title="Share" class="fa fa-share fa-lg"></span></a>
</div>
<div class="pull-right-custom text-muted"><small><?=$post->post_likes?> Like - <?=$post->post_comments?> Comment</small></div>
<div class="clear"></div>
<div id="<?=$post->pid?>Comment" class="collapse">
<br>
<form name="addcommentajax" id="addcommentajax" post-id="<?=$post->pid?>" class="form-horizontal" role="form" method="POST">
<div class="input-group">
<input type="text" id="comment-text" class="form-control input-sm" placeholder="Add Comment">
<span class="input-group-btn">
<button type="submit" class="btn btn-sm btn-default">Publish</button>
</span>
</div>
</form>
</div>
</div>
</div>
<?php endforeach; ?>
<?php endif; ?>
我需要在此循环<?php foreach ($allposts as $post): ?>中再做一次foreach，以便在$postcomments->post_id = $post->post_id
