Question

我想创建一个帖子并且能够添加不同的类别，所以我制作了这段代码

  public function store(Request $request)
{
  $this->validate($request,[
    'title' => 'required',
    'body' => 'required',
    'name'=>'required'
  ]);

  $post = new \App\Post([
      'title' => $request->get('title'),
      'body' => $request->get('body')
    ]);
     $post->save();

     foreach ($request->name as $data) {
       $categories = new \App\Category();
       $categories->name = $request->get('name');
       //dd($categories);
      $post->categories()->save($categories);
     }
      return redirect()->route('create');
}

模特邮报

public function categories(){return $this->hasMany(\App\Category::class, 'post_id');}

模型类别

public function something(){return $this->belongsTo(\App\Solicitud::class, 'post_id');}

HTML

<form class="form-horizontal" role="form" method="POST" action="{{ route('store_data') }}">
                    {{ csrf_field() }}
                    <div class="form-group{{ $errors->has('title') ? ' has-error' : '' }}">
                        <label for="title" class="col-md-4 control-label">title:</label>
                        <div class="col-md-6">

                      <input type="text" name="title" placeholder="Cantidad" class="form-control"  value="{{ old('title') }}" />

                            @if ($errors->has('title'))
                                <span class="help-block">
                                    <strong>{{ $errors->first('title') }}</strong>
                                </span>
                            @endif
                        </div>
                    </div>
                    <div class="form-group{{ $errors->has('body') ? ' has-error' : '' }}">
                        <label for="body" class="col-md-4 control-label">Body:</label>
                        <div class="col-md-6">

                          <input type="text" name="body" placeholder="Cantidad" class="form-control"  value="{{ old('body') }}" />

                            @if ($errors->has('body'))
                                <span class="help-block">
                                    <strong>{{ $errors->first('body') }}</strong>
                                </span>
                            @endif
                        </div>
                    </div>
                    <div class="form-group{{ $errors->has('name') ? ' has-error' : '' }}">
                      <table class="table table-bordered" id="dynamic_field">
                        <thead>
                          <tr>
                          </tr>
                        </thead>
                        <tbody>
                          <tr>
                            <td><input type="text" name="name[]" placeholder="Name" class="form-control name_list"  value="{{ old('name') }}" /></td>
                            <td><button type="button" name="add" id="add" class="btn btn-success"> + </button></td>
                          </tr>
                        </tbody>
                       </table>
                    </div>
                    <div class="form-group">
                        <div class="col-md-6 col-md-offset-4">
                            <button type="submit" class="btn btn-primary">
                                Create
                            </button>
                        </div>
                        <div class="col-md-6 col-md-offset-4">
                          <a class="btn btn-info" href="{{ URL::previous() }}">back</a> <br>
                        </div>
                    </div>
                  </form>

Scritps：

      <script>
$(document).ready(function(){
   var i=1;
   $('#add').click(function(){
        i++;
        $('#dynamic_field').append('<tr id="row'+i+'"><td><input type="text" name="name[]" placeholder="Name" class="form-control name_list" /></td><td><button type="button" name="remove" id="'+i+'" class="btn btn-danger btn_remove">-</button></td></tr>');
   });
   $(document).on('click', '.btn_remove', function(){
        var button_id = $(this).attr("id");
        $('#row'+button_id+'').remove();
   });

});
</script>

但是我收到了这个错误。当我提交表格时

类型错误：传递给Illuminate \ Database \ Grammar :: parameterize（）的参数1必须是数组类型，给定整数，在C：\ xampp \ htdocs \ proyect \ vendor \ laravel \ framework \ src \ Illuminate中调用681行上的\ Database \ Query \ Grammars \ Grammar.php。

“类型错误：传递给Illuminate \ Database \ Grammar :: parameterize（）的参数1必须是数组类型，给定整数，在C：\ xampp \ htdocs \ proyect \ vendor \▶”中调用“

如果在输入为空的情况下按提交，我会收到此错误

htmlspecialchars（）期望参数1为字符串，给定数组（查看：C：\ xampp \ htdocs \ proyect \ resources \ views \ create.blade.php）

但是如果我编辑代码，就会以这种方式工作但只添加一个类别。

$categories = new \App\Category();
       $categories->name = $request->get('name');
       //dd($categories);
      $post->categories()->save($categories);

我希望我已经解释得很好并且谢谢：）

Laravel在表格中多次插入
