我真的不知道問題出在哪裏，說實話。Dropzone在後端Laravel中沒有有效的MIME類型？
可能是Dropzone，Laravel（5.4），...所以我真的希望即使是一個想法也許能幫助我克服這個問題。
當我上傳文件，我沒有得到任何的js問題，但Laravel拋出我下面的錯誤（每個文件）：
調用未定義的方法的Symfony \分量\ HttpFoundation \文件\ UploadedFile的::店（ ）
這是我的後端代碼（錯誤被設置在portfolioStore法）：
<?php
namespace App\Http\Controllers;
use App\Http\Requests\UploadPortfolioPhotoRequest; use App\PortfolioPhoto; use DebugBar\DebugBar; use Illuminate\Http\Request; use Illuminate\Support\Facades\Storage;
class AdminController extends Controller {
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('auth');
}
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
return view('admin.home');
}
public function portfolioIndex()
{
$photos = PortfolioPhoto::all();
return view ('admin.portfolio.index')->with('photos', $photos);
}
public function portfolioStore(UploadPortfolioPhotoRequest $request)
{
foreach ($request->files as $photo) {
$filename = $photo->store('photos');
$test = PortfolioPhoto::create([
'filename' => $filename,
'title' => 'title',
'alt' => 'alt'
]);
}
return 'Upload successful!';
}
public function portfolioDelete()
{
return view ('admin.portfolio.index');
} }
在任何情況下，這是我的懸浮窗的配置：
var previewNode = document.querySelector("#template");
previewNode.id = "";
var previewTemplate = previewNode.parentNode.innerHTML;
previewNode.parentNode.removeChild(previewNode);
var myDropzone = new Dropzone(document.body, { // Make the whole body a dropzone
url: "/admin/portfolio", // Set the url
thumbnailWidth: 80,
thumbnailHeight: 80,
parallelUploads: 20,
previewTemplate: previewTemplate,
autoDiscover: false,
autoQueue: false, // Make sure the files aren't queued until manually added
previewsContainer: "#previews", // Define the container to display the previews
clickable: ".fileinput-button", // Define the element that should be used as click trigger to select files.
headers: {
'x-csrf-token': document.querySelectorAll('meta[name=csrf-token]')[0].getAttributeNode('content').value,
}
});
myDropzone.on("addedfile", function(file) {
// Hookup the start button
file.previewElement.querySelector(".start").onclick = function() { myDropzone.enqueueFile(file); };
});
myDropzone.on("sending", function(file) {
// And disable the start button
file.previewElement.querySelector(".start").setAttribute("disabled", "disabled");
});
// Hide the total progress bar when nothing's uploading anymore
myDropzone.on("queuecomplete", function(progress) {
var alertMsg = document.createElement('div'),
actions = document.getElementById('actions');
alertMsg.setAttribute('class', 'alert bg-success');
alertMsg.innerHTML = 'Files successfully uploaded<a href="#" class="pull-right"><em class="fa fa-lg fa-close"></em></a>';
actions.parentNode.insertBefore(alertMsg, actions.nextSibling);
});
// Setup the buttons for all transfers
// The "add files" button doesn't need to be setup because the config
// `clickable` has already been specified.
document.querySelector("#actions .start").onclick = function() {
myDropzone.enqueueFiles(myDropzone.getFilesWithStatus(Dropzone.ADDED));
};
document.querySelector("#actions .cancel").onclick = function() {
myDropzone.removeAllFiles(true);
};

所以現在我想知道這個問題是否與一個MIME類型爲不確定造成的存儲方法到不行。或者我應該尋找其他地方？
任何意見，想法表示歡迎:)

如果你是'dd（$ photo）;'在foreach中，它是否返回一個對象？ – mbozwood
