我一直在尝试将我的用户的User_id与Creator_id匹配,以在我的帖子中显示创建者用户名 但我正试图从非对象错误获取属性,我不能得到它周围
我控制器中的功能 postcontroller.php:
public function index()
{
$allusers = users::getusers();
$posts = DB::table('posts')->get();
foreach ($posts as $posts) {
foreach ($allusers as $allusers) {
if ($posts->creator_id == $allusers->user_id) {
array_push($posts,$allusers->username);
}
}
}
return view('blog',['posts'=>$posts]);
}
我模型中的功能:
public static function getusers(){
$allusers = users::all();
return $allusers;
}

您在foreach循环中使用相同的变量名称:
foreach ($posts as $post) {
foreach ($allusers as $user) {
if ($post->creator_id == $user->user_id) {
array_push($post,$user->username);
}
}
}
但是对于您的问题,您应该尝试在Post Model中添加它
public function user(){
return $this->belongsTo(User::class, 'creator_id', 'user_id);
}
然后在你看来:
@foreach($posts as $post)
{{ $post->user->name }}
@endforeach

您的users表是否有像user_id这样的列?
我认为您已使用帖子creator_id检查了用户表ID。
