我必须在Laravel中查询。首先,获得一个帖子。第二,得到所有评论。我的问题是,我无法正确追加Laravel Query Builders中get()
的两个数组输出。
当我尝试加入他们时,该帖子出现了3次,因为我对该帖子有3条评论。因此,我尝试array_push
而不是加入。现在输出是这样的。
[
{
"id": 44,
"image": "9178hello.jpg",
"description": "Lorem ipsum dolor sit amit!",
"address": "internet",
"lat": 45.435,
"long": 2312.3,
"created_at": "1 hour ago"
},
[
{
"comment": "my comment.... my comment 1.....",
"created_at": "2015-01-11 17:24:27"
},
{
"comment": "my comment.... my comment 2.....",
"created_at": "2015-01-11 17:24:29"
},
{
"comment": "my comment.... my comment 3.....",
"created_at": "2015-01-11 17:24:30"
}
]
]
我怎样才能成为:
[
{
"id": 44,
"image": "9178hello.jpg",
"description": "Lorem ipsum dolor sit amit!",
"address": "internet",
"lat": 45.435,
"long": 2312.3,
"created_at": "1 hour ago",
"comments" : {
list all the comments here...
}
}
]
以下是查询:
$disaster = Disaster::where('name', '=', $name)->first(['id']);
$post = DB::table('posts')
->join('locations', 'locations.id', '=', 'posts.location')
->join('users', 'users.id', '=', 'posts.user_id')
->select('posts.id', 'posts.image', 'posts.description', 'locations.address', 'locations.lat', 'locations.long', 'posts.user_id', 'users.firstname', 'users.lastname', 'posts.created_at')
->where('posts.disaster_id', '=', $disaster->id)
->where('posts.id', '=', $id)
->get();
if (empty($post)) {
return ['error' => 'no post found'];
}
$post[0]->created_at = Carbon::parse($post[0]->created_at)->diffForHumans();
$comments = DB::table('comments')
->select('comment', 'created_at')
->where('post_id', '=', $post[0]->id)
->get();
array_push($post, $comments);
return $post;
答案 0 :(得分:1)
你可以这样做
$array = array_merge($post, array('comments' => $comments));
文档:array_merge
这会将带有comments key
的评论附加到帖子数组。
既然您正在使用Laravel,为什么不使用 Eloquent 关系?只需在帖子和评论之间建立一对多的关系,并以任何你想要的方式获得它们。
