您好，我的数据库中有错误。用户在用户表中注册，现在他必须发布广告。我正在尝试在广告表中获取他的 ID。但它返回给我这个错误：

SQLSTATE [23000]: 完整性约束违规: 1048 Column 'user_id' can not be null (SQL: insert into ads( user_id, services, head, level_study, language, experience, localization, description, contact, updated_at, created_at) 值(?, Household, Housekeeper, BAC + 2, a little, 2years, Yopougon, pnjjjk , 09789070, 2019-06-05 08:31:38, 2019-06-05 08:31:38))

public function store(Adstore $request)
{
    $validated = $request->validated();
    $user_id = Auth::user()['id'];
    $ad = new Ad();
    $ad->user_id = $user_id;
    $ad->services = $validated['dropdown_service'];
    $ad->titre = $validated['title'];
    $ad->niveau_etude = $validated['dropdown_etude'];
    $ad->langue = $validated['langue'];
    $ad->experience = $validated ['experience'];
    $ad->localisation = $validated ['local'];
    $ad->description = $validated ['description'];
    $ad->contact = $validated ['contact'];
    $ad->save();
    return redirect()->route('accueil')->with('success','Votre annonce a été postée.');
}

Answer 1

对代码进行一些更改，如下所示：

在控制器中：

public function store(Adstore $request)
{
    $validated = $request->validated();

    $user_id = Auth::user()->id;

    $ad = Ad::create([
        'user_id' => $user_id,        
        'services' => $validated['dropdown_service'],        
        'titre' => $validated['title'],        
        'niveau_etude' => $validated['dropdown_etude'],        
        'langue' => $validated['langue'],        
        'experience' => $validated['experience'],        
        'localisation' => $validated['local'],        
        'description' => $validated['description'],        
        'contact' => $validated['contact'],        
    ]);

    if($ad){
        return redirect()->route('accueil')->with('success','Votre annonce a été postée.');
    } else {
        return redirect()->route('accueil')->with('error','Something went wrong.');
    }    
}

Answer 2

而不是“$user_id = Auth::user()['id'];” 使用这个：“$user_id = Auth::user()->id;” 它会起作用的。

Answer 3

您必须像这样访问身份验证用户 ID $user_id = Auth::user()->id;
