如果控制器上还有什么搜索功能?

Question

所以我有一个具有基本搜索功能的控制器，我想知道当用户单击搜索按钮时是否存在数据，我希望它返回带有错误消息的同一页面，但如果数据不存在，我想返回另一个页面。 我该怎么做？ 我的代码如下：

控制器：

public function search(Request $request, $companyID, $entityType)
	{
		$data = [];
		$intentTypes = DiraQuestion::select('intent')->where('company_id', $companyID)->groupBy('intent')->get();
		foreach ($intentTypes as $intent) 
		{
			$data[$intent->intent] = $intent->intent;
		}
		$q = $request->q;
	    $user = DiraQuestion::select('eVal')->where('company_id', $companyID)->where('eType', $entityType)->where('eVal','LIKE','%'.$q.'%')->groupBy('eVal')->get();
	    return view('AltHr.Chatbot.addType', compact('data','entityType','companyID'))->withDetails($user)->withQuery($q);
	}

我的当前视图页面显示是否存在，如果不存在，则显示表单：

@if(isset($details))
<div class="container-fluid container-fixed-lg">
	<div class="row">
		<div class="col-md-12">
			<div class="panel panel-default">
				<!-- <div class="panel-heading">
					<div class="panel-title"><b>{{ $query }}</b></div>
					<div class="clearfix"></div>
				</div> -->
				<div class="panel-body">
					<div class="form-group edit-response-container">
						<div class="col-md-12">
							@foreach($details as $user)
				            	<p><span style="color:red;">{{$user->eVal}}</span> is already included!</p>
				            @endforeach
				        </div>
						@if($details->isEmpty())
						<form action="{{action('AltHrChatbotChatbotController@addQType', [$companyID, $entityType])}}" method="post">
							{{csrf_field()}}
							<!-- @if(empty($data))
							<p>No predefined intents.</p>
							@else -->
							<div class="col-md-12">
								<div class="form-group form-group-default required">
									<label>New Type</label>
									<input type="text" class="form-control" name="entityValue" placeholder="{{$query}}" value="{{$query}}" required readonly/>
								</div>
							</div>
							<!-- <div class="col-md-12">
								<div class="form-group form-group-default required">
									<label>New Question</label>
									<input type="text" class="form-control" name="question" placeholder="Enter Sample Question" required>
								</div>
							</div>
							<div class="col-md-12">
								<div class="form-group form-group-default required">
									<label>Intent</label>
									<select class="full-width" name="intent" data-init-plugin="select2" required>
										<option selected disabled></option>
						                @foreach($data as $datas)
						                <option value="{{$datas}}">{{$datas}}</option>
						                @endforeach
									</select>
								</div>
							</div> -->
							<div class="col-md-12">
								<div class="new-field">
									<div class="form-group-attached">
										<div class="form-group form-group-default required">
											<label>Synonyms:</label>
											<input type="text" class="form-control" name="syn" placeholder="Enter Synonyms" />
										</div>
									</div>
								</div>
								<p><i>*Enter All Synonyms Separating With ','</i></p>
							</div>
							<div class="col-md-12">
								<br>
								<!-- <button type="button" class="btn alt-btn-green alt-btn btn-xs add-new">Add Synonym</button> -->
								<button type="submit" class="btn alt-btn-green alt-btn btn-xs">Save</button>
								<a href="{{action('AltHrChatbotChatbotController@newTest', [$companyID, $entityType])}}" class="btn alt-btn-green alt-btn btn-xs">test</a>
							</div>
							@endif
						</form>
						@endif
					</div>
				</div>
			</div>
		</div>
	</div>
</div>
@endif

路线：

Route::post('search/{companyID}/{entityType}','ChatbotChatbotController@search');

正如您目前看到的，如果数据存在，它会在同一页面上显示错误消息，但是如果没有数据，它会在同一页面上显示一个表单本身..我希望它在找不到数据时路由到另一个页面。

如果你想在你的@if里面include另一个snippet，那么你可以这样做：

@include('route.to.view')

它将在该 url 中搜索blade视图并插入 html，以防存在$data
