php - 搜索查询条件不起作用 - Laravel 5.7

Question

我认为这是：

<div class="container">
<div class="row">
    <div class="col-lg-12 col-md-12">
        <form class="search-form search-form-basic" action="/candidates/index" method="post">
        {{ csrf_field() }}
        <div class="form-row">              
            <div class="col-md-4 form-group">
                <label for="search_email">First name:</label>
                <input type="text" name="search_first_name" id="search_first_name" class="form-control" @if(isset(Session::get('inputs')['search_first_name'])) value="{{ Session::get('inputs')['search_first_name'] }}" @endif>
            </div> 
            <div class="col-md-4 form-group">
                <label for="search_last_name">Last name:</label>
                <input type="text" name="search_last_name" id="search_last_name" class="form-control" @if(isset(Session::get('inputs')['search_last_name'])) value="{{ Session::get('inputs')['search_last_name'] }}" @endif>
            </div> 
            <div class="col-md-4 form-group">
                <label for="search_round_number">Round Number:</label>

            </div>

              <option  value="source">Source</option>
              <option  value="recommendation">Recommended</option>                
              <option  value="created_at">Applied</option>
            </select>
            <div class="col-md-4 form-group">
                <label for="search_from_date">From:</label>
                <input type="date" name="search_from_date" id="search_from_date" class="form-control"

            </div>  
        </div>
        <div class="form-row">
            <div class="col-md-12 col-lg-12">
                <button type="submit" class="btn btn-custom"><i class="fa fa-search" aria-hidden="true"></i>Search</button>

我的控制器：

    public function index(Request $request) {

    if($request->isMethod('post')){
        $search_first_name =    $request->search_first_name;
        $search_last_name =     $request->search_last_name;
        $search_email =         $request->search_email;
        $search_round_number =  $request->search_round_number;
        $search_location =      $request->search_location;
        $search_from_date =      $request->search_from_date;
        $search_to_date =      $request->search_to_date;

        $options = Input::get('options');

        $recOrSource = null;

        if($options == 'recommendation' || $options == 'source')   {
                $recOrSource = Input::get('options');
                $options == null;  

        }

        $candidate = DB::table('candidates')
                    ->when($search_first_name, function ($query) use ($search_first_name) {
                        return $query->where('first_name', 'like', '%' . $search_first_name . '%');
                    })
                    ->when($search_last_name, function ($query) use ($search_last_name) {
                        return $query->where('last_name', 'like', '%' . $search_last_name . '%');
                    })
                    ->when($search_email, function ($query) use ($search_email) {
                        return $query->where('email', $search_email);
                    })
                    ->when($search_round_number, function ($query) use ($search_round_number) {
                        return $query->where('round_number', $search_round_number);
                    })
                    ->when($search_location, function ($query) use ($search_location) {
                       return $query->where('location', $search_location);
                    })                           
                    ->when($recOrSource, function ($query) use ($recOrSource,$search_from_date,$search_to_date) {
                       return $query->where(!empty($recOrSource))->whereBetween('created_at', array($search_from_date, $search_to_date));
                    })                       
                    ->when($options, function ($query) use ($options,$search_from_date,$search_to_date  ) {
                       return $query->whereBetween($options, array($search_from_date, $search_to_date));
                    })                                                                                      
                    ->orderBy('first_name', 'asc')
                    ->orderBy('last_name', 'asc')
                    ->get();                     

                    Session::flash('inputs', [
                        'search_first_name' => $search_first_name,
                        'search_last_name' => $search_last_name,
                        'search_email' => $search_email,
                        'search_round_number' => $search_round_number,
                        'search_from_date' => $search_from_date,
                        'search_to_date' => $search_to_date,
                        'search_location' => $search_location

                        ]);
                }else{
                     Session::forget('inputs');


        $candidate = Candidate::orderBy('first_name', 'asc')
                        ->orderBy('last_name', 'asc')
                        ->get();
                    }

        return view('/candidates/index', [
            'candidate' => $candidate
        ]);

当我选择“来源”作为选项之一并输入起止日期时，我收到此错误：

找不到列：1054 'where 子句'中的未知列'1'（SQL：select * from candidateswhere 1is null 并且created_at在 2015-8-8 和 2019-1-1source之间以及 2015-8-8和 2019-1-1 之间按first_nameasc、last_nameasc 排序）

但是， dd($recOrSource) 正在返回正确的值；我看不出这个“1”来自哪里，以及为什么这部分运行

                        ->when($options, function ($query) use ($options,$search_from_date,$search_to_date  ) {
                       return $query->whereBetween($options, array($search_from_date, $search_to_date));
                    })     

当我有

            if($options == 'recommendation' || $options == 'source')   {
                $recOrSource = Input::get('options');
                $options == null;  

        }
