Question

我有一个Laravel程序，可以保存表格数据并上传一些图片。在验证中，有两个规则。图片是必需的，并且必须是图片类型（jpg，jpeg，png）。但是，验证仅检查文件类型，而不检查“必需”。即使没有图像，它也允许用户提交。为什么？

public function updateImages(Request $request, $id)
{
    $validatedData = $request->validate([
        'image' => 'required',
        'image.*' => 'image|mimes:jpeg,png,jpg|max:2048',
    ],
        [
            'image.*.image' => 'Format Error: Please uplaod image in a png or jpg format',
        ]);
    $item = Post::find($id);
    $existing_count = Photo::where('post', $item->id)->count();
    $countrequest = sizeof($request->file('image'));
    $count = $existing_count + $countrequest;
    if ($count >= 6) {
        return back()
            ->withInput()
            ->withErrors(['Only 5 images can be uploaded!']);
    }
    $upload = $this->imageUpload($item, $request);

    return redirect()->back()->with('message', 'Image Updated');
}

Answer 1

通过image.*申请要求。例如-

image.*' => 'require|image|mimes:jpeg,png,jpg|max:2048',

尝试此解决方案。它将起作用。

您可以使用Laravel Request Validation

要创建表单请求类

class GzipFilterSpec
    extends PlaySpec
    with GuiceOneServerPerSuite
    with FutureAwaits
    with DefaultAwaitTimeout {

  override def fakeApplication(): Application =
    new GuiceApplicationBuilder()
      .loadConfig(env => Configuration.load(env))
      .build()

  "Server" must {
    "compress responses" in {
      val wsClient: WSClient = app.injector.instanceOf[WSClient]
      val appStatusUrl = s"http://localhost:$port/app_status"
      val gzipResponse: WSResponse = await(
        wsClient
          .url(appStatusUrl)
          .addHttpHeaders(ACCEPT_ENCODING -> "gzip")
          .get())
      val response: WSResponse = await(wsClient.url(appStatusUrl).get())
      println(response.body)
      println(gzipResponse.body)
      checkGzippedBody(gzipResponse, response.body)
    }
  }
}

转到app / Http / Requests添加规则

php artisan make:request ImageUpdateRequest

在您的控制器上

public function authorize()
{
    return true;
}

public function rules()
{
    return [
        'image' => 'required|image|mimes:jpeg,png,jpg|max:2048'
    ];
}

验证表单未部分检查
