Question

我正在尝试通过laravel控制器中的简单查询来更新数据库记录。

这是我的代码，

import discord

表格

DB::table('calender_events')->where('id', '=', '1')->update(
    array(
        'title' => $request->title,

    )
);

当我单击“保存”按钮时，它会按预期重定向到主页，但数据库没有更新。我也使用插入和选择查询，没有任何错误。是的，数据库中有一条ID为1的记录。请帮忙！

Answer 1

您应该这样编写代码

DB::table('calender_events')->where('id',1)->update(
   array(
      'title' => $request->title,

   )
);

Answer 2

这是我最后想出的工作代码，

ion-content

    public function update(Request $request)
    {
         $image = $request->file('avatar');
    if($image!=null){
        $avatar_name = $request->get('NIC').'.'.$image->getClientOriginalExtension();
        $folder = '/uploads/avatars/';
       // $filePath = $folder . $avatar_name;
        $this->uploadOne($image, $folder, 'public', $avatar_name);
    }else{
        $avatar_name = null;

        ]);  
    }else{
        DB::table('users')->insert([
            [

        ]);  
        }
    return redirect()->route('user.index')->withStatus(__('User successfully created.'));
    }

    public function uploadOne(UploadedFile $uploadedFile, $folder = null, $disk = 'public', $filename = null)
    {
        $name = !is_null($filename) ? $filename : Str::random(25);

        $path =storage_path('uploads/avatars/'.$filename.'');

        if( Storage::exists($path)){
          
         Storage::disk('public')->delete('uploads/avatars/'.$filename.'');  
        }
        $file = $uploadedFile->storeAs($folder, $name, $disk);
        return $file;
    }

}

我不得不制作另一个刀片并将编辑功能移到另一个控制器上，这是因为我使用的是免费的仪表板模板，它内置了身份验证功能，但阻止了部分免费用户使用，无论如何都要感谢您的帮助。
