当我点击编辑按钮时给我错误

Question

当我点击编辑按钮时出现错误，我现在不明白是什么问题，请帮助我

Trying to get property 'id' of non-object (View: C:\xampp\htdocs\ytl\resources\views\profile\edit.blade.php)

这是我的 userprofilecontroller

public function edit( Request $request, $id){

    $user_profile_id = UserProfile::where('id', '=', $id)->firstOrFail();

    $exchanges = Exchange::pluck('exchange','id')->all();
    $markets = Market::pluck('market','id')->all();
    $countries = Country::pluck('country','id')->all();
    $brokerage_company = BrokerageCompany::pluck ('brokerage_company','id')->all();
    $user_profile = UserProfile::pluck('charge_intraday','charge_delivery','charge_per_lot','charge_per_order')->all();



    return view('profile.edit', compact('user_profile_id','exchanges','markets','countries','brokerage_company','user_profile'));

}
public function update(Request $request, $id){

    $user_profile_id = UserProfile::findOrFail($id);
   $input = $request->except( 'brokerage_company','user_profile');
  $user_id = $user_profile->update($input);


    return redirect('/profile');

}

这是profile\index.blade.php文件

您似乎误解了 Pluck 方法。 Pluck 是通过键将几个属性从数组中取出来。与 selecting 数据库中的列无关。

我猜你想 select 单曲 UserProfile。正确的做法如下：

public function edit(Request $request, $id){

    $user_profile = UserProfile::findOrFail($id); // Select a UserProfile by ID or fail

    $exchanges = Exchange::all('exchange', 'id'); 
    $markets = Market::all('market','id');
    $countries = Country::all('country','id');
    $brokerage_company = BrokerageCompany::all ('brokerage_company','id');
    // I dont know what you want with this statement?
    // $user_profile = UserProfile::pluck('charge_intraday','charge_delivery','charge_per_lot','charge_per_order')->all();

    return view('profile.edit', compact('user_profile','exchanges','markets','countries','brokerage_company'));

}
