顯示laravel中大多數帖子的用戶5.2

Question

我想顯示前5個最熱門的用戶，大多數帖子是這樣的：User1（5帖子）User5（3帖子）User2（2帖子）.... - 在我的AppServiceProvider.php

view()->composer('questions.side', function($view){ 
$users = User::leftJoin('questions','user.id','=','questions.user_id'‌​‌​‌​‌​) 
->selectRaw('‌​us‌​er‌​.*, count(questions.user_id) AS total') 
->groupBy('users.id') 
->orderBy('total','DESC') 
->skip(‌​‌​‌​0) 
->take(5) 
->get‌​()‌​; 

$view->with('users', $users); 

}); 

在我的側視圖

：

foreach($usersas $user) { 
    var_dump($user); 
} 

，但我得到這個問題：

FatalErrorException in AppServiceProvider.php line 18: syntax error, unexpected '‌​‌​‌​‌​' (T_STRING)

Answer 1

錯誤是因爲SQL語法錯誤的 你的$用戶

$users = User::leftJoin('questions','user.id','=','questions.user_id'‌​‌​‌​‌​)->selectRaw('‌​us‌​er‌​.*, count(questions.user_id) AS total')->groupBy('users.id')->orderBy('total','DESC')->skip(‌​‌​‌​0)->take(5)->get‌​()‌​; 

改變這種

$users = DB::table('users')->leftJoin('questions','user.id','=','questions.user_id'‌​‌​‌​‌​)->select('‌​us‌​er‌​.*', count('questions.user_id') 'AS total')->orderBy('total','DESC')->skip(‌​‌​‌​0)->take(5)->get‌​()‌​; 

，我建議你的var_dump（$用戶），解析片文件中之前他們
