Question

4电子商务网站
我试图过滤我的数据，但我做错了每个过滤器工作正常，如颜色品牌价格，但当我在性别部分之后我dd($products)时过滤性别的返回数据但是当我在返回视图之前dd($products)时返回0数据意味着什么这是我的form

{!! Form::open(['url' => 'category/' . $tag . '/filter', 'files'=>false, 'id' => 'color_form'])   !!}

    Price Filter 
    <input name="price" id="ex2" type="text" class="span2" value="" data-slider-min="10" data-slider-max="2000" data-slider-step="5" data-slider-value="[250,450]" onchange="checkBoxHandler()"/>

    <li class="">
        <input type="checkbox" name="gender[]" id="men" value="male" onchange="checkBoxHandler()"> Men's
    </li>

    <li class="">
        <input type="checkbox" name="gender[]" id="woman" value="female" onchange="checkBoxHandler()"> Woman's
    </li>

    @foreach($colors as $color)
        <input type="checkbox" name="color[]" id="color{{ $color->name }}" value="{{ $color->name }}" onchange="checkBoxHandler()">
        <div style="width:25px; height:25px; background:{{ $color->name }}; border:1px solid black; margin:0px 3px 0px 3px;  display:inline-block;"></div> &nbsp {{ $color->name }}
    @endforeach

    @foreach($brands as $brand)
        <input type="checkbox" name="brand[]" id="brand{{ $brand->name }}" value="{{ $brand->name }}" onchange="checkBoxHandler()">
        {{ $brand->name }}<br>
    @endforeach

    @foreach($sizes as $size)
        <input type="checkbox" name="size[]" id="size{{ $size->name }}" value="{{ $size->name }}" onchange="checkBoxHandler()">
        {{ $size->name }}<br>
    @endforeach

{!! Form::close() !!}

这是我的controller

public function newinindex(Request $request){
  if(request()->has('gender')||request()->has('price')||request()->has('color')||request()->has('brand')){
      if (request()->has('gender')) {
         $products = Product::orderBy('created_at', 'desc')->where('gender', request('gender'))->newin()->paginate(20);
      }
      if (request()->has('price')) {
          $products = Product::orderBy('created_at', 'desc')->newin()->whereBetween('price', explode(',', $request->price))->paginate(20);
      }
      if (request()->has('color')) {
             $products = Product::orderBy('created_at', 'desc')->newin()->whereHas('colors', function ($query) {
              $query->where('name', request('color'));
          })->paginate(20);
      }
      if (request()->has('brand')) {
         $products = Product::orderBy('created_at', 'desc')->newin()->whereHas('brands', function ($query) {
              $query->where('name', request('brand'));
          })->paginate(20);
      }
    }
    else  {
       $products = product::orderBy('created_at', 'desc')->newin()->paginate(20);
    } 
  $sizes = size::orderBy('created_at', 'desc')->paginate(20);
  $colors = color::orderBy('created_at', 'desc')->paginate(20);
  $brands = brand::orderBy('created_at', 'desc')->paginate(20);

  return view('newin.index' ,compact('products', 'brands', 'colors', 'sizes'));
}

Answer 1

性别字段是一个数组！请参阅以下链接并尝试使用字段名称中的值。

example

Answer 2

您正在使用gender复选框作为数组。修改您的controller

$products = Product::orderBy('created_at', 'desc')->whereIn('gender', request('gender'))->newin()->paginate(20);

whereIn方法验证给定列的值是否包含在给定数组中。
