檢索值是在laravel

一對多的關係我有應與其他三個表，活動，捐贈&機會顯示所選專案編號的詳細信息，也該特定IDS DATAS刀片頁面。但我只能檢索項目表值而不是其他3個表。沒有錯誤信息。請幫助使用laravel查詢單個頁面中的所有4個表格。檢索值是在laravel

我ProjectController文件：

public function getDetailedProject() 
{ 
    $data=Project::all()->where('pid', 35); 
    $eve=Event::all()->where('pro_id', 35); 
    $don=Donation::all()->where('pro_id', 35); 
    $opp=Opportunity::all()->where('pro_id', 35); 
    return view('other.detailedProject')->with('data',$data); 
}

我DetailedProject.blade.php文件代碼：

@extends('templates.default') 

@section('content') 

    @foreach($data as $row) 
    <ul>

您只將'$ data'傳遞到視圖中。 '$ eve'，'$ don'和'$ opp'不是'$ data'的一部分。你實際上從來沒有打過關係。 – aynber

不要使用'所有（） - >其中（）'，這會從數據庫中的所有數據，然後過濾收集這是令人難以置信的低效率。使用'where（） - > get（）'來過濾數據庫，並只獲取符合條件的數據。 – Devon

我試過了，但仍然出現錯誤。那麼我應該如何編碼？ –

試試這個代碼，希望工程！

$data=Project::where('pid', 35)->get(); 
$eve=Event::where('pro_id', 35)->get(); 
$don=Donation::where('pro_id', 35)->get(); 
$opp=Opportunity::where('pro_id', 35)->get(); 
return view('other.detailedProject', compact('data', 'eve', 'don', 'opp'));

我試過了，但收到了錯誤信息。「未定義的常量數據的使用 - 假設 '數據'（查看：C：\ XAMPP \ htdocs中\博客\資源\意見\其它\ detailedProject.blade.php）」。這個。如何解決它？ –
