Question

我在Laravel中为广告/属性构建了一个应用程序。我有一个带有复选框的过滤器的搜索表单。当我从同一个请求中选择两个选项时遇到问题，例如供需，需求为PropertyBidAsk，我只能从需求中得到结果，而不能同时从两者中得到结果，而且我想在表单提交后同时检查两个结果。供求是类别表中类别列中的值。任何帮助表示赞赏。这是我的代码。

CategoryController.php：

public function search(Request $request, Property $property)
{
    $category = $property->category;

    $query = Property::query();

    if ($request->has('propertyBidAsk')) {
        $request->get('propertyBidAsk');
    }

    if ($request->propertyBidAsK == 'supply' && $request->propertyBidAsk== 'demand') {
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%' . $request->propertyBidAsk . '%');
        });
    } elseif ($request->propertyBidAsk == 'supply') {
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%' . 'supply' . '%');
        });
    } else if ($request->propertyBidAsk == 'demand') {
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%' . 'demand' . '%');
        });
    }

    $results = $query->paginate(6);

    return view('search', compact('category', 'results', 'request'));
}

search.blade.php：

<div class="col-md-2 mb-6">
    <h5>Payment Method</h4>
    <div class="d-block my-3">
        <div class="custom-control custom-checkbox">
            <input id="supply" name="propertyBidAsk" value="supply" type="checkbox" class="custom-control-input" @if(old('propertyBidAsk', $request->propertyBidAsk ?? 'default') === 'supply') checked @endif>
            <label class="custom-control-label" for="supply">supply</label>
        </div>
        <div class="custom-control custom-checkbox">
            <input id="demand" name="propertyBidAsk" value="demand" type="checkbox" class="custom-control-input" @if(old('propertyBidAsk', $request->propertyBidAsk ?? 'default') === 'demand') checked @endif>
            <label class="custom-control-label" for="demand">demand</label>
        </div>
    </div>
</div>

Answer 1

要获得具有相同名称attr的多选输出，请将复选框输入的名称更新为array作为propertyBidAsk []。您将获得输入数组。

<input id="supply" name="propertyBidAsk[]" value="supply" type="checkbox" class="custom-control-input" @if(old('propertyBidAsk', $request->propertyBidAsk ?? 'default') === 'supply') checked @endif>


<input id="demand" name="propertyBidAsk[]" value="demand" type="checkbox" class="custom-control-input" @if(old('propertyBidAsk', $request->propertyBidAsk ?? 'default') === 'demand') checked @endif>

在控制器中将获得该值。

public function search(Request $request, Property $property)
{
    $category = $property->category;

    $query = Property::query();

    if ($request->has('propertyBidAsk')) {
        $request->get('propertyBidAsk');
    }


    $propertyBidAsk = $request->input('propertyBidAsk'); //$propertyBidAsk will get in array

    if (in_array('supply', $propertyBidAsk)  && in_array('demand', $propertyBidAsk)){
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%demand%')->orWhere('category', 'like', '%supply%')
        });
    } else if(in_array('supply', $propertyBidAsk)){
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%' . 'supply' . '%');
        });
    } else  if(in_array('demand', $propertyBidAsk)){
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%' . 'demand' . '%');
        });
    }

    $results = $query->paginate(6);

    return view('search', compact('category', 'results', 'request'));
}

Answer 2

@Shivendra Singh回答，您可以做到这一点，您也可以这样做

<input id="supply" name="propertyBidAsk1" value="supply" type="checkbox" class="custom-control-input" @if(old('propertyBidAsk', $request->propertyBidAsk ?? 'default') === 'supply') checked @endif>


<input id="demand" name="propertyBidAsk2" value="demand" type="checkbox" class="custom-control-input" @if(old('propertyBidAsk', $request->propertyBidAsk ?? 'default') === 'demand') checked @endif>

您会发现表单元素中的名称不能相同，它将始终获得第一个值。

然后在您的控制器中

if (!empty($request->propertyBidAsK1) && !empty($request->propertyBidAsk2) {
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%' . $request->propertyBidAsk1 . '%')
                  ->orWhere('category', 'like', '%' . $request->propertyBidAsk2 . '%');
        });
    } elseif (!empty($request->propertyBidAsk1)) {
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%' . 'supply' . '%');
        });
    } else if (!empty($request->propertyBidAsk2)) {
        $query->whereHas('category', function ($query) use ($request) {
            $query->where('category', 'like', '%' . 'demand' . '%');
        });
    }
