獲取表單上具有其他值的行的ID Laravel

Question

如何獲取具有名稱值的id值？

我有這樣的形式：

<form enctype="multipart/form-data" id="projectclientexist" name="projectclientexist"> 
    @foreach ($clients as $key => $client) 
    <div class="radio"> 
     <div class="col-md-3"> 
      <label><input type="radio" name="client" value="{{$client->name}}">{{$client->name}}</label> 
     </div> 
    </div> 
    @endforeach 
    <input type="submit" value="Crear relacion Proyecto-Cliente" id="relationclientexist" name="relationclientexist" class="btn btn-success"> 
</form> 

我該怎麼辦呢取值，其命名爲價值客戶的ID？

public function storeProjectsClientsIfExist (Request $request) 
{ 
    $client_project->project = new Client_Project(); 

    $client_project->client_id = DB::table('clients') 
           ->where('id', DB::raw("(select max(id) ")); 

    $client_project->project_id = DB::table('projects') 
           ->where('id', DB::raw("(select max(`id`) from projects)")) 
           ->first() 
           ->id; 
    $client_project->save(); 
} 

非常感謝，如果有關於代碼的任何問題，你可以問它。

我想你可以試試這個：

public function storeProjectsClientsIfExist(Request $request) 
     { 
      $client_project->project = new Client_Project(); 
      $client_project->client_id = DB::table('clients')->where('name', $request->client)->first()->id; 
      $client_project->project_id = DB::table('projects')->where('id', DB::raw("(select max(`id`) from projects)"))->first()->id; 
      $client_project->save(); 
     } 

希望爲你工作!!!

古怪的問道。如果我正確理解你的questino，你想獲得所選客戶的ID？

如果是這樣的話，看來，場value屬性具有存儲ID：

<label><input type="radio" name="client" value="{{$client->id}}">{{$client->name}}</label> 

然後，控制器，你選中的客戶是這樣的：

$clientID = $request->input('client'); // or $request->client; 
$clientObj = Client::find($clientID); // Your client model object, if needed. Equals to: DB::table('clients')->find($clientID); 

編輯：我認爲你的Creating default object from empty value錯誤發生是因爲你嘗試在$client_project->project = new Client_Project();的非對象上添加一個屬性。您必須將$client_project定義爲stdClass的對象（它是一個默認類，沒有屬性，沒有方法，有點像空的javascript對象）。

所以我們在這裏：

public function storeProjectsClientsIfExist (Request $request) 
{ 
    $clientID = $request->input('name'); // get the name field value. 

    $client_project = new \stdClass(); // define the var as an object. 

    $client_project->project = new Client_Project(); 
    $client_project->client_id = $clientID; 
    // currently the next line get the last project added in DB 
    $client_project->project_id = DB::table('projects') 
     ->where('id', DB::raw("(select max(`id`) from projects)")) 
     ->first() 
     ->id; 

    // I think "$client_project->save();" will not work 
    $client_project->project->save(); 

    return view('my.view'); // or redirect()->route('my.route') or what you want 
}

如果你想選擇的客戶端的，你必須通過客戶端的ID的價值，而不是名稱

@foreach ($clients as $key => $client) 
      <div class="radio"> 
        <div class="col-md-3"> 
        <label><input type="radio" name="client" value="{{$client->id}}">{{$client->name}}</label> 
        </div> 
      </div> 
     @endforeach

如果您有相關的名稱僅ID那就試試這個：

$client_id = DB::table('clients')->where('name',$request->client))->first()->id; 

如果許多ID與給定名稱相關聯，那麼你可以使用這個：

$client_ids = DB::table('clients')->where('name',$request->client))->pluck('id');
