evrything used to work fine , but now i get an error off connexion
aborted ,when i try to uplaod file. so i figure out a solution is to
add the host name before calling the ws php to upload file
exp(http://195.25.55.21:81/php/ws_upload.php) but this work only for
my local machine others get connection forbiden even that they can
access to the domaine they get only error permission when they try to
upload files.
To make it more confusing when i try to call the function like
that('/php/ws_upload.php') only files who has small taill accepted ,
even in the php.ini by default i get 2M , note with this method i get
connection aborted failed to load ressource /php/ws_upload.php.
i downlond the project and i tried in my machine evrything works fine
, means that it's not an eror in my code
i'm just unsure as to what could be stopping the upload,quiring minds want to know. Thank you

I'm trying to build a simple website builder that allow users to save their generated html created with Vue component and see it at a certain URL.
Because of it I have to store and retrieve the html generated but I have some problems with retrieving of the code. Here is my step:
When user click "save" this function is fired, that select the portion of HTML that include the "website" built by the user:
saveBuilders: function () {
let pages = [];
let builders = $('[id*="builder-container-"]');
$.each(builders, function (key, builder) {
let singleElem = $(builder).attr('id');
pages.push(clearElement.html());
});
this.storeInDb(pages);
},
storeInDb: function (pagesList) {
axios.post("/landing-page/store", {
name: this.name,
description: this.description,
html: pagesList
})
.then(function (response) {
console.log('Cool');
})
.catch(function (error) {
console.log('ERROR', error.response);
});
},
The Axios request is handled by this function that store the html portion in DB
public function store(Request $request)
{
$data = $request->all();
$html = $data['html'];
$landingPage = new LandingPage();
$landingPage->name = $data['name'];
$landingPage->description = $data['description'];
$landingPage->user_id = Auth::user()->id;
$landingPage->html = json_encode($html);
try {
$landingPage->save();
return 'true';
} catch (exception $e) {
return $e;
}
}
Now when the user visit a certain URL, for keep thing simple suppose is example.it/website/0, this function is fired:
public function show($landing_id)
{
try {
$landingPage = LandingPage::where([
'id' => $landing_id,
'user_id' => Auth::user()->id
])->first();
} catch (\Exception $e) {
$landingPage = null;
}
if ($landingPage != null) {
//GET THE HTML
$page = json_decode($landingPage->html);
return view('landing_page.show')->with('page', $page)
} else {
abort(404, 'Error');
}
}
And this the blade where I'm trying to re-create the Vue.js environment
<body>
<span id="countdown"></span>
<div id="builder-pagina">
<builder>
{!! $page !!}}
</builder>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<script src="{{asset('js/landing_page/app.js')}}"></script>
</body>
</html>
I thought that having the html generated by vue similar to something like that into the DB...
<div data-v-29b64d26="" >
<h1>This piece of code was stored into my DB</h1>
<div data-v-56f62f0a="">
</div>
</div>
...you could create everything working simply by pasting the code and by using the same js file used for compiling vue.js.
I've tried pass the entire code by props but is not working. Also tried with slot. Any suggestions?
I'm trying to send an image to my server. I'm keep getting the error: Current request is not a multipart request. When i test it in Postman it works fine.
This is my html form:
function saveImageToProduct() {
var formData = new FormData(document.querySelector("#newImagesForm"));
var encData = new URLSearchParams(formData.entries());
fetch("/uploadFile", { method: 'POST', body: encData })
.then(response => Promise.all([response.status, response.json()]))
.then(function([status, myJson]) {
if (status == 200) {
console.log("succeed!");
} else {
console.log("failed!");
}
})
.catch(error => console.log(error.message));
return false;
}
<form enctype="multipart/form-data" novalidate="novalidate" id="newImagesForm" method="post">
<div>
<p>Selecteer een afbeelding:</p>
<input id="file" name="file" type="file"/>
</div>
<br>
<div>
<button id="button" onclick="return saveImageToProduct()" class="btn btn-lg btn-info btn-block">
<span>Voeg aanbieding toe</span>
</button>
</div>
</form>
Backend Java code:
#PostMapping("/uploadFile")
public ProductImage uploadFile(#RequestParam("file") MultipartFile file) {
String fileName = fileStorageService.storeFile(file);
String fileDownloadUri = ServletUriComponentsBuilder.fromCurrentContextPath()
.path("/uploads/")
.path(fileName)
.toUriString();
return new ProductImage(fileName, fileDownloadUri,
file.getContentType(), file.getSize());
}
When i try to send the image i'm getting a 500 error in the backend:
2019-03-10 19:40:33.588 ERROR 5668 --- [io-9001-exec-10] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Current request is not a multipart request] with root cause org.springframework.web.multipart.MultipartException: Current request is not a multipart request
When i do it in Postman it works fine like the following image shows:
Any idea what i'm doing wrong here? Thanks in advance
The code below should do the job:
You basically create a new Form object and append the file data to it.
You are able to add multiple data attributes to it by adding more "data.append" lines.
function uploadPicture() {
var input = document.querySelector('input[type="file"]')
console.log(productID);
var data = new FormData()
data.append('file', input.files[0])
fetch('/uploadFile/', {
method: 'POST',
body: data
})
.then(response => Promise.all([response.status, response.json()]))
.then(function([status, myJson]) {
if (status == 200) {
console.log("succeed!");
} else {
console.log("failed!");
}
})
.catch(error => console.log(error.message));
}
HTML:
<input type="file" name="file" id="fileinput">
<input type="submit" value="Upload" onclick="uploadPicture()">
You can try modifying it -
var formData = new FormData(document.querySelector("#newImagesForm")[0]);
My thought process:
When the show page opens, get the article's id with JavaScript.
Check this id exist or not in cookie
If not exists, write it into cookie and send an ajax request, the backend updates view times.
If exists, do nothing.
Demo:
View：
<div class="card">
<div class="card-block text-xs-center">
<h5 class="card-title">{{$article->title}}</h5>
<hr class="m-y-2">
<h6 class="card-subtitle text-muted">date：{{$article->created_at->format('Y-m-d')}}
views：{{$article->view_times}}</h6>
</div>
<div class="card-block">
<p class="card-text">{{$article->content}}</p>
</div>
</div>
Controller：
class ArticlesController extends Controller
{
//`show` method
public function show($id)
{
$article = Article::findOrFail($id);
return view('show', compact('article'));
}
//the method of updating view times.
public function statistics(Request $request)
{
$id = $request->input('id');
$article = Article::findOrFail($id);
$view_time=$article->view_time;
$article->view_time=$view_time+1;
$article->save();
}
}
JavaScript：
Vue.http.headers.common['X-CSRF-TOKEN'] = document.querySelector('meta[name=csrf-token]').getAttribute('content')
Vue.http.options.emulateJSON = true;
var vm = new Vue({
el: "body",
data: function(){
return{
id:[]
}
},
created() {
//1、Get the article's id.Do I have to send an ajax request? Is there any other way?
this.$http.get('article/get-id').then((response) => {
// success callback
this.id=response.data;
}, (response) => {
// error callback
});
//2、After Getting the `id`，check it in cookie,I don't know how to do it?
//3、If not exists,write it into cookie and send an ajax request,how to write the if() sentence?
if(){
var formData = new FormData();
var id=this.id;
formData.append('id',id);
this.$http.patch('article/statistics', formData,{
before(request) {
if (this.previousRequest) {
this.previousRequest.abort();
}
this.previousRequest = request;
}
}).then((response) => {
// success callback
}, (response) => {
// error callback
});
}
}
});
Questions:
There are three questions, shown as comments in JavaScript code above.
I'm trying to display the results from a submitted form, AngularJS > PHP > Back but I'm getting nothing. I've tried a lot of different ways and according to all of google I'm doing it right but the console log just says that it's undefined.
Here is the submit function:
$scope.testProcessForm = function() {
$http({
method : 'POST',
url : 'test.php',
data : $scope.formData,
headers : {'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}
})
.success(function(data) {
if (data.errors) {
// Showing errors.
$scope.errorselectedServices = data.errors.selectedservices;
$scope.errorincEmail = data.errors.incemail;
} else {
$scope.submissionMessage = data.messageSuccess;
$scope.test= data.test;
The PHP:
$data['test'] = $test;
echo json_encode($data);
HTML:
<div ng-show="test">{{test}}</div>
Why am I getting "test is undefined" and no div? If I put an echo into PHP I get the proper reply back. It doesn't appear to hang anywhere in the code after some debugging. What am I doing wrong?

I found the error. Apparently you have to quote the variable into the array;
$data['faxSender'] = "$faxSenderPhoneNo";
Now works as intended.
EDIT:
Well it worked to a point. My divs still weren't displaying. After logging with console.log(data) I could see that I had a lot of undefined indexes but my data array was there so I didn't understand why I couldn't access it.
I fixed the undefined stuff and then suddenly every div was displayed. Not a clue why PHP decides to dump all that info into my $data array.
2nd edit: Apparently .success is deprecated. Using .then instead with error_reporting(1); seems to always give me an array with data that angular then can use.
Since you are JSON encoding data in php file, file returning a String. so, you will need decode JSON to Java script object first. Also, you $http returns angular promise($q service). I am not sure about using
.success
method. Instead use
.then
.then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
// decode JSON firs since you are sending JSON from PHP
var data = JSON.parse(response);
$scope.test = data.test;
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
// Handle error here
});
I'm a beginner to angular.js but I have a good grasp of the basics.
What I am looking to do is upload a file and some form data as multipart form data. I read that this isn't a feature of angular, however 3rd party libraries can get this done. I've cloned angular-file-upload via git, however I am still unable to post a simple form and a file.
Can someone please provide an example, html and js of how to do this?
First of all
You don't need any special changes in the structure. I mean: html input tags.
<input accept="image/*" name="file" ng-value="fileToUpload"
value="{{fileToUpload}}" file-model="fileToUpload"
set-file-data="fileToUpload = value;"
type="file" id="my_file" />
1.2 create own directive,
.directive("fileModel",function() {
return {
restrict: 'EA',
scope: {
setFileData: "&"
},
link: function(scope, ele, attrs) {
ele.on('change', function() {
scope.$apply(function() {
var val = ele[0].files[0];
scope.setFileData({ value: val });
});
});
}
}
})
In module with $httpProvider add dependency like ( Accept, Content-Type etc) with multipart/form-data. (Suggestion would be, accept response in json format)
For e.g:
$httpProvider.defaults.headers.post['Accept'] = 'application/json, text/javascript';
$httpProvider.defaults.headers.post['Content-Type'] = 'multipart/form-data; charset=utf-8';
Then create separate function in controller to handle form submit call.
like for e.g below code:
In service function handle "responseType" param purposely so that server should not throw "byteerror".
transformRequest, to modify request format with attached identity.
withCredentials : false, for HTTP authentication information.
in controller:
// code this accordingly, so that your file object
// will be picked up in service call below.
fileUpload.uploadFileToUrl(file);
in service:
.service('fileUpload', ['$http', 'ajaxService',
function($http, ajaxService) {
this.uploadFileToUrl = function(data) {
var data = {}; //file object
var fd = new FormData();
fd.append('file', data.file);
$http.post("endpoint server path to whom sending file", fd, {
withCredentials: false,
headers: {
'Content-Type': undefined
},
transformRequest: angular.identity,
params: {
fd
},
responseType: "arraybuffer"
})
.then(function(response) {
var data = response.data;
var status = response.status;
console.log(data);
if (status == 200 || status == 202) //do whatever in success
else // handle error in else if needed
})
.catch(function(error) {
console.log(error.status);
// handle else calls
});
}
}
}])

EDIT: Added passing a model up to the server in the file post.
The form data in the input elements would be sent in the data property of the post and be available as normal form values.
It is more efficient to send the files directly.
The base64 encoding of Content-Type: multipart/form-data adds an extra 33% overhead. If the server supports it, it is more efficient to send the files directly:
Doing Multiple $http.post Requests Directly from a FileList
$scope.upload = function(url, fileList) {
var config = {
headers: { 'Content-Type': undefined },
transformResponse: angular.identity
};
var promises = fileList.map(function(file) {
return $http.post(url, file, config);
});
return $q.all(promises);
};
When sending a POST with a File object, it is important to set 'Content-Type': undefined. The XHR send method will then detect the File object and automatically set the content type.
Working Demo of "select-ng-files" Directive that Works with ng-model1
The <input type=file> element does not by default work with the ng-model directive. It needs a custom directive:
angular.module("app",[]);
angular.module("app").directive("selectNgFiles", function() {
return {
require: "ngModel",
link: function postLink(scope,elem,attrs,ngModel) {
elem.on("change", function(e) {
var files = elem[0].files;
ngModel.$setViewValue(files);
})
}
}
});
<script src="//unpkg.com/angular/angular.js"></script>
<body ng-app="app">
<h1>AngularJS Input `type=file` Demo</h1>
<input type="file" select-ng-files ng-model="fileList" multiple>
<h2>Files</h2>
<div ng-repeat="file in fileList">
{{file.name}}
</div>
</body>
You can check out this method for sending image and form data altogether
<div class="form-group ml-5 mt-4" ng-app="myApp" ng-controller="myCtrl">
<label for="image_name">Image Name:</label>
<input type="text" placeholder="Image name" ng-model="fileName" class="form-control" required>
<br>
<br>
<input id="file_src" type="file" accept="image/jpeg" file-input="files" >
<br>
{{file_name}}
<img class="rounded mt-2 mb-2 " id="prvw_img" width="150" height="100" >
<hr>
<button class="btn btn-info" ng-click="uploadFile()">Upload</button>
<br>
<div ng-show = "IsVisible" class="alert alert-info w-100 shadow mt-2" role="alert">
<strong> {{response_msg}} </strong>
</div>
<div class="alert alert-danger " id="filealert"> <strong> File Size should be less than 4 MB </strong></div>
</div>
