Question

我遇到一些问题，其中我的刀片服务器模板的验证失败，并且在相关表上选择了下拉菜单。我试图搜索答案，但找不到。

要暂时将validate函数中数组内部的“ business_unit_id”字段注释掉，以避免发生错误。

在控制器更新功能中：

    $item = CostCenter::findOrFail($id);
    $validatedData = $request->validate([
        'code' => 'bail|min:4|required|max:6',
        'descr' => 'bail|min:4|required|max:50',
        'business_unit_id' => 'required|integer',
    ]);

    $item->fill($validatedData);
    $item->business_unit_id = $request->businessUnit;

    $item->save();
    $request->session()->flash('status', 'Cost centers record was updated!');

    return redirect()->route('costCenters.show', ['cost_centers' => $item->id]);

在刀片模板中：

        <label for="businessUnit" class="col-sm-2 col-form-label">Business Unit</label>
            <select name="businessUnit" class="form-control">
                @foreach (App\Models\BusinessUnit::all() as $data)
                    <option value="{{ $data->id }}"
                        {{ old('business_unit_id', $cost_centers->business_unit_id ?? '1')
                            != $data->id ?: 'selected' }}>
                        {{ $data->code }} - {{ $data->descr }}
                    </option>
                @endforeach
            </select>

收到的通知是“必须输入业务单位ID字段”。和我的错误帮助程序。

Answer 1

$validatedData = $request->validate([
    'code' => 'bail|min:4|required|max:6',
    'descr' => 'bail|min:4|required|max:50',
    'businessUnit' => 'required|integer',
]);

使用businessUnit代替business_unit_id 因为我们必须使用选择标记的名称... 不要使用选项标签的ID。

Answer 2

您可以尝试使用此代码...并在代码中使用use关键字，例如 use Validator;

    $rules = [
           'code' => 'bail|min:4|required|max:6',
           'descr' => 'bail|min:4|required|max:50',
           'businessUnit' => 'required|integer|exists:business_unit,id',
    ];

    $message = [
        'code.required' => 'code is required.',
        'descr.required' => 'description field is required.',
        'businessUnit.required' => 'The business unit id field is required.',

    ];

     $validator = Validator::make($request->all(), $rules,$message);
      if ($validator->fails()) {
      $arr = array("status"=>400,"msg"=>$validator->errors()- 
     >first(),"result"=>array());
      }
       else
       {
      your code write in this section
        }

Answer 3

对于控制器中的任何请求数据验证，您可以尝试如下操作：

$rule=array(
        'code' => 'bail|min:4|required|max:6',
        'descr' => 'bail|min:4|required|max:50',
        'business_unit_id' => 'required|integer',
);
$validator= Validator::make($request->all(),$rule);
