Php Larvel如何使用FormRequest验证多个文件（图像）

作为表单的一部分，我希望提交多达五个图像，并在带有自定义错误消息的FormRequest中验证它们

表单的文件提交部分如下所示：

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class StoreListingFormRequest extends FormRequest
{
/**
 * Determine if the user is authorized to make this request.
 *
 * @return bool
 */
public function authorize()
{
    return true;
}

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        'title' => 'required|max:255',
        'body' => 'required|max:2000',
        'price' => 'required|max:100|regex:/^\d{1,13}(\.\d{1,4})?$/',
        'contact_details' => 'required',
        "images"    => "required|array|min:1|max:5",
        'images.*' => 'required|mimes:jpg,jpeg,png,bmp|max:2000',
        'category_id' => [
            'required',
            \Illuminate\Validation\Rule::exists('categories', 'id')->where(function ($query) {
                $query->where('usable', true);
            })
        ],
        'area_id' => [
            'required',
            \Illuminate\Validation\Rule::exists('areas', 'id')->where(function ($query) {
                $query->where('usable', true);
            })
        ]
    ];
}

public function messages()
{
    return [
        'contact_details.required' => 'At least one method of contact is required for your advert.',
        'images.min' => 'Please upload one or more images',
        'images.max' => 'A maximum of five images are allowed',
        'images.*.mimes' => 'Only jpeg,png and bmp images are allowed',
        'images.*.max' => 'Sorry! Maximum allowed size for an image is 2MB',
    ];
}
}

最多选择五个图像。。。
@如果（$errors->has（'images'））
{{$errors->first（'images'）}

我的FormRequest如下所示：

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class StoreListingFormRequest extends FormRequest
{
/**
 * Determine if the user is authorized to make this request.
 *
 * @return bool
 */
public function authorize()
{
    return true;
}

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        'title' => 'required|max:255',
        'body' => 'required|max:2000',
        'price' => 'required|max:100|regex:/^\d{1,13}(\.\d{1,4})?$/',
        'contact_details' => 'required',
        "images"    => "required|array|min:1|max:5",
        'images.*' => 'required|mimes:jpg,jpeg,png,bmp|max:2000',
        'category_id' => [
            'required',
            \Illuminate\Validation\Rule::exists('categories', 'id')->where(function ($query) {
                $query->where('usable', true);
            })
        ],
        'area_id' => [
            'required',
            \Illuminate\Validation\Rule::exists('areas', 'id')->where(function ($query) {
                $query->where('usable', true);
            })
        ]
    ];
}

public function messages()
{
    return [
        'contact_details.required' => 'At least one method of contact is required for your advert.',
        'images.min' => 'Please upload one or more images',
        'images.max' => 'A maximum of five images are allowed',
        'images.*.mimes' => 'Only jpeg,png and bmp images are allowed',
        'images.*.max' => 'Sorry! Maximum allowed size for an image is 2MB',
    ];
}
}

有几件事不适用于图像验证：

首先，如果我在images数组上设置min:1，如果我不提交图像，它不会返回错误消息，但是如果我将其设置为2，它将返回我的自定义错误消息

我无法获取任何错误消息以返回图像..mimes'或'images..max'

我到底做错了什么？

我知道了

   public function rules()
{
    return [
        'title' => 'required|max:255',
        'body' => 'required|max:2000',
        'price' => 'required|max:100|regex:/^\d{1,13}(\.\d{1,4})?$/',
        'contact_details' => 'required',
        "images"    => "required|array|min:1|max:5",
        'images.*' => 'required|mimetypes:image/jpeg,image/png,image/bmp|max:2000',
        'category_id' => [
            'required',
            \Illuminate\Validation\Rule::exists('categories', 'id')->where(function ($query) {
                $query->where('usable', true);
            })
        ],
        'area_id' => [
            'required',
            \Illuminate\Validation\Rule::exists('areas', 'id')->where(function ($query) {
                $query->where('usable', true);
            })
        ]
    ];
}

public function messages()
{
    return [
        'contact_details.required' => 'At least one method of contact is required for your advert.',
        'images.required' => 'Please upload one or more images',
        'images.max' => 'A maximum of five images are allowed',
        'images.*.mimetypes' => 'Only jpeg,png and bmp images are allowed',
        'images.*.max' => 'Sorry! Maximum allowed size for an image is 2MB',
    ];
}

然后在视图中：

 <div id="dzone" class="form-group dropzone {{ ($errors->has('images') || $errors->has('images.*')) ? ' has-error' : '' }}">
                            <div class="fallback">
                                <label for="images[]">Select up to five images...</label>
                                <input name="images[]" type="file" multiple />
                            </div>
                            @if ($errors->has('images'))
                                <span class="help-block">
                                    {{ $errors->first('images') }}
                                </span>
                            @endif
                            @if ($errors->has('images.*'))
                                <span class="help-block">
                                    {{ $errors->first('images.*') }}
                                </span>
                            @endif
                        </div>

最多选择五个图像。。。
@如果（$errors->has（'images'））
{{$errors->first（'images'）}
@恩迪夫
@如果（$errors->has（'images.*'））
{{$errors->first（'images.*'）}
@恩迪夫

文件或任何多输入验证错误都应检查密钥名称

它们的键名随数字（即：images.0）动态出现，并且它们都包含关键字“images”，因此我们可以使用它来捕获这些错误

因此，简单的检查应该完成以下工作：

 @if($errors->has('images.*'))
      @foreach($errors->get('images.*') as $key => $error)
           <div class="error">{{ $errors->first($key) }}</div>
      @endforeach
 @endif

@if（$errors->has（'images.*））
@foreach（$errors->get（'images.*'）作为$key=>$error）
{{$errors->first（$key）}
@endforeach
@恩迪夫

我现在可以开始执行以下操作：“images.required'=>'请上载一个或多个图像”，“images.max'=>'最多允许五个图像'，但数组项仍然没有任何内容我查看是否添加$errors->has（'images.0'））我可以得到错误消息，但肯定有更好的方法。在“images.*”上，请删除所需内容并放置映像，同时尝试使用此sintax映像。*.file=>并让我知道这些场景的输出
