Front End File Upload using Vue and Winter Cms - laravel

I'm trying to upload images from a Vue frontend via Illuminate/Http/Request to WinterCMS.
Vue finds the file and i can console.log the File object, but I'm unsure how to get this over the api. for example I've tried
public function saveImage(Request $req){
$images = $req->files('images');
}
which doesn't work, nor does
public function saveImage(Request $req){
$images = $req['images'];
}
I'm using a controller to handle my routes eg:
Route::post('/saveImage', 'Author\Project\Controllers\ProductControl#saveImage');
I've added an attachOne relation to the plugin as usual and my form has enctype="multipart/form-data"
I've had this problem before and got around it by converting images to base64 but this project will have quite a few images and I don't want to go down that route again.
Any suggestions greatly appreciated

You can send images as regular post and use regular $request->file('images') method in your Laravel controller.
You can use Javascript FormData object. For example;
<div>
<input type="file" #change="handleImages" multiple>
<button #click="uploadImages">Upload!</button>
</div>
data: () => ({
images: []
}),
methods: {
handleImages (event) {
this.images = event.target.files
},
uploadImages () {
const formData = new FormData();
for (const i of Object.keys(this.images)) {
formData.append('images', this.images[i])
}
axios.post('/saveImage', formData, {
}).then((res) => {
console.log(res)
})
}
}

Get image from blob Laravel vue

First of all, this is the start of where I am at as a similar post
Store blob as a file in S3 with Laravel
I am sending a photo from VueJS to Laravel. It is coming as multipart/form-data.
Vue Code:
export default {
emits: ['onClose'],
props: ['isOpen'],
data: function() {
return {
serverOptions: {
process: (fieldName, file, metadata, load, error) => {
const formData = new FormData();
formData.append(fieldName, file, file.name);
axios({
method: "POST",
url: '/chat/room/upload',
data: formData,
headers: {
"Content-Type": "multipart/form-data"
}
})
.then(() => {
load();
})
.catch(() => {
error();
});
}
},
files: [],
};
},
methods: {
handleFilePondInit: function () {
console.log('FilePond has initialized');
// example of instance method call on pond reference
this.$refs.pond.getFiles();
console.log(this.$refs.pond.getFiles());
},
},
Laravel Controller:
public function uploadImage(Request $request)
{
// This is what this is SUPPOSED to do. Grab the file from the frontend
// Bring it here. Store it in S3, return the path with the CDN URL
// Then store that URL into the DB as a message. Once that is done, then
// Broadcast the message to said room.
if ($request->has('upload')) {
$files = $request->get('photo');
$urls = [];
foreach ($files as $file) {
$filename = 'files/' . $file['name'];
// Upload File to s3
Storage::disk('digitalocean')->put($filename, $file['blob']);
Storage::disk('digitalocean')->setVisibility($filename, 'public');
$url = Storage::disk('digitalocean')->url($filename);
$urls[] = $url;
}
return response()->json(['urls' => $urls]);
}
// broadcast(new NewChatMessage($newMessage))->toOthers();
// return $newMessage;
}
First: I want to state that if there is something wrong with the current code, just know its because ive been playing around with this for 3 hours now and been trying anything. I am sure at one point I had it close but somehow screwed it up along the way so I am more looking for fresh eyes to show me my error.
That being said, the other part to take into account is in DevTools under Network I can clearly see the blob and can load it up, I can also see the "upload" item and under there the form data which shows the following
------WebKitFormBoundary7qD7xdmiQO9U1Ko0
Content-Disposition: form-data; name="photo"; filename="6A8B48B4-F546-438E-852E-C24340525C20_1_201_a.jpeg"
Content-Type: image/jpeg
------WebKitFormBoundary7qD7xdmiQO9U1Ko0--
it clearly also shows photo: (binary) so I am completely confused as to what I am doing wrong. The ULTIMATE goal here is to get the image, store it as public in S3/DigitalOcean then grab the public URL to the file and store in the DB.
Any help would be GREATLY appreciated!

Unable to read filelist object in Laravel controller from vue

I'm creating an application where user is filing up a form with possibility to send multiple files along
In vue.js I'm creating formData with an array of files and with an object with the rest of inputs fields. I'm posting that with Axios.
In request in Laravel controller I can't access my filelist-object.
I can see the
$request->My_Array,
but I can read the data store inside
I have tried to use loops also I have try :
$request->all();
$request->file('files');
My input
<input class="browse" V-on::change="onImageChange" type="file">
My vue.js component
onImageChange(event) {
this.files.push(event.target.files);
},
submit(e) {
e.preventDefault();
let currentObj = this;
const fd = new FormData();
for (let i = 0; i < this.files.length; i++) {
fd.append('IoFiles[]', this.files[i]);
}
console.log(this.files);
fd.append('IoFiles', this.files);
fd.append('fields', JSON.stringify(this.fields));
axios.post('/io',
fd,
{headers: {'Content-Type': 'multipart/form-data'}})
.then(function (response) {
currentObj.output = response.data;
})
.catch(function (error) {
currentObj.output = error;
});
},
My Laravel controller
public function store(Request $request)
{
if ($request->IoFiles) {
$medias = $request->IoFiles;
foreach ($medias as $image) {
return $image->getClientOriginalName();//That give me an error
}
}
}
There are a couple of issues with your code.
Firstly, V-on::change="onImageChange" should be:
v-on:change="onImageChange"
Please note:
the lowercase v for v-on
the single :
Alternatively, you could write #change="onImageChange".
Secondly, event.target.files returns a FileList not a single file so you need to change your onImageChange code to the following be able to get the file itself:
onImageChange(event) {
this.files.push(event.target.files[0]); //Note the [0] after files
},

Is FormData object required with Vuejs to upload file to laravel backend?

Is the FormData object absolutely necessary to work with files and to upload them to my backend made with laravel?
Secondly, would it be a good practice to wrap all form inputs in a FormData object, even non file input?
Currently I try this
<input type="file" #change="onVideoSelected" name="explenationVideo">
My method logic:
onVideoSelected(event) {
this.form.video = event.target.files[0];
}
My data structure
data() {
return {
form: {
name : '',
contentType : 'video',
imageGroup : [],
video : null,
difficulty : '',
}
}
}
And when I submit
axios.post('/backoffice/exercises', this.form)
.then(({data}) => {
this.messages.push('Exercice ajouté!');
});
But when I try to view the detail in the backend like
dd($request->file('video'));
I have a null value.

Having trouble updating a scope more than once

I'm using angular with the ionic framework beta 1.
Here's my ng-repeat html:
<a href="{{item.url}}" class="item item-avatar" ng-repeat="item in restocks | reverse" ng-if="!$first">
<img src="https://server/sup-images/mobile/{{item.id}}.jpg">
<h2>{{item.name}}</h2>
<p>{{item.colors}}</p>
</a>
</div>
And here's my controllers.js, which fetches the data for the ng-repeat from a XHR.
angular.module('restocks', ['ionic'])
.service('APIservice', function($http) {
var kAPI = {};
API.Restocks = function() {
return $http({
method: 'GET',
url: 'https://myurl/api/restocks.php'
});
}
return restockAPI;
})
.filter('reverse', function() {
//converts json to JS array and reverses it
return function(input) {
var out = [];
for(i in input){
out.push(input[i]);
}
return out.reverse();
}
})
.controller('itemController', function($scope, APIservice) {
$scope.restocks = [];
$scope.sortorder = 'time';
$scope.doRefresh = function() {
$('#refresh').removeClass('ion-refresh');
$('#refresh').addClass('ion-refreshing');
restockAPIservice.Restocks().success(function (response) {
//Dig into the responde to get the relevant data
$scope.restocks = response;
$('#refresh').removeClass('ion-refreshing');
$('#refresh').addClass('ion-refresh');
});
}
$scope.doRefresh();
});
The data loads fine but I wish to implement a refresh button in my app that reloads the external json and updates the ng-repeat. When I call $scope.doRefresh(); more than once, I get this error in my JS console:
TypeError: Cannot call method 'querySelectorAll' of undefined

It looks like it's related to a bug, as per:
https://github.com/driftyco/ionic/issues/727
Which was referenced from:
http://forum.ionicframework.com/t/show-hide-ionic-tab-based-on-angular-variable-cause-error-in-background/1563/9
I'm guessing it's pretty much the same issue.
Maybe try instead using angular.element(document.getElementById('refresh')) for a possible workaround (guessing).

ASP.NET MVC 3 - File upload through AngularJS

I'm using AngularJS with my pages, and I have a doubt: when I do post with my form, how can I pass some selected file to my ASP.NET MVC 3 Controller?
Check this out:
My form:
<form enctype="multipart/form-data" ng-controller="FilesController" ng-submit="submitingForm()">
<div>
Choose the file:
<input type="file" onchange="angular.element(this).scope().setSelectedFile(this)" />
</div>
<input type="submit" value="Confirm" />
</form>
And the AngularJS Controller:
var module = angular.module('application', []);
(function (ang, app) {
function FilesController($scope, $http) {
$scope.setSelectedFile = function (element) {
$scope.$apply(function($scope) {
$scope.selectedFile = element.files[0];
});
};
$scope.submitingForm = function() {
$http.post(url, ???????).success(function() {
// How to pass that selected file for my ASP.NET controller?
});
}
}
app.controller("FilesController", FilesController);
})(angular, module);
Thank you!!!
I am not quite familiar with AngularJS but if you are attempting to upload a file using an AJAX request you can forget about it. That's not something that could be done. You could use the HTML5 File API if you want to upload files asynchronously to the server. There's an entire section dedicated to this.
And if your client browsers do not support the HTML5 File API you could use a File Upload plugin such as FineUploader or Uploadify (there are quite many others, just google).
My Approach is to use FormData.
Create a input tag like this.
<input id="imgInp" type="file" aria-label="Add photos to your post" class="upload" name="file" onchange="angular.element(this).scope().LoadFileData(this.files)" multiple="" accept="image/*" style="margin-top: -38px; opacity: 0; width: 28px;">
And in your Angular Controller create a method LoadFileData(inputFiles) as bellow:
var formData = new FormData();
$scope.LoadFileData = function (files) {
for (var file in files) {
formData.append("file", files[file]);
}
};
Now in formData variable you will have the uploaded files. Just send it to asp.net mvc controller.
$scope.submit = function () {
$http.post("/YourController/Method", formData, {
withCredentials: true,
headers: { 'Content-Type': undefined },
transformRequest: angular.identity
}).success(function (response) {
}
In Server side, Asp.NET MVC 4 controller you will have the files
var files = Request.Files;
