将数据从<option>插入到Laravel的数据库中

Question

试图在CRUD应用程序中使用Option窗体插入数据。但其表示，

SQLSTATE [23000]：完整性约束违规：1048列 'site_category' 不能为空（SQL：插入company（site_category，category_rest，user_id，updated_at，created_at）值（，，1，2017年-09-01 8时30分09秒，2017年9月1日8时30分09秒））

查看

     {!! Form::open(['action' => 'CompanyController@store', 'method' => 'POST']) !!} 
         <div class="form-group"> 
          <label for="siteCategory">Choose your website category</label><br> 
          <select class="custom-select" id="siteCategory"> 
            <option name="test1" value="test1">Option 1</option> 
            <option name="test2" value="test2">Option 2</option> 
            <option name="test3" value="test3">Option 3</option> 
          </select> 
         </div> 
         <div class="form-group"> 
          <label for="restrictCategory">Choose your website categories restrictions</label><br> 
          <select class="custom-select" id="restrictCategory" multiple> 
            <option name="test4" value="test4">Option 1</option> 
            <option name="test5" value="test5">Option 2</option> 
            <option name="test6" value="test6">Option 3</option> 
          </select> 
         </div> 
         <button type="submit" class="btn btn-primary">Add Company</button> 
        {!! Form::close() !!} 

控制器

public function store(Request $request) 
{ 
    $company = new Company; 
    $company->site_category = $request->input('test1'); 
    $company->site_category = $request->input('test2'); 
    $company->site_category = $request->input('test3'); 
    $company->category_rest= $request->input('test4'); 
    $company->category_rest= $request->input('test5'); 
    $company->category_rest= $request->input('test6'); 
    $company->user_id = auth()->user()->id; //sync with user 
    $company->save(); 

    return redirect('/dashboard/company'); 
} 

我想我的行动控制器错了，但什么？

Answer 1

您必须为您的元素命名，它们表示“$ request”关联数组中的键。

<select class="custom-select" id="siteCategory" name="siteCategory"> 

和

<select class="custom-select" id="restrictCategory" name="restrictCategory[]" multiple> // set name attribute to an array to get all the selected choices 

控制器

public function store(Request $request) 
{ 
    $company = new Company; 
    $company->site_category = $request->input('siteCategory'); 
    $company->category_rest= implode(',', $request->input('restrictCategory')); // store it as string separated by commas 
    $company->user_id = auth()->user()->id; //sync with user 
    $company->save(); 

    return redirect('/dashboard/company'); 
}
