Here is my HTML form:
<form name="myForm" ng-submit="">
<input ng-model='file' type="file"/>
<input type="submit" value='Submit'/>
</form>
I want to upload an image from local machine and want to read the content of the uploaded file. All this I want to do using AngularJS.
When I try to print the value of $scope.file it comes as undefined.
This question is related to
angularjs
angularjs-fileupload
Below is working example of file upload:
http://jsfiddle.net/vishalvasani/4hqVu/
In this one function called
setFiles
From View which will update the file array in controller
or
You can check jQuery File Upload using AngularJS
You can achieve nice file and folder upload using flow.js.
https://github.com/flowjs/ng-flow
Check out a demo here
http://flowjs.github.io/ng-flow/
It doesn't support IE7, IE8, IE9, so you'll eventually have to use a compatibility layer
The <input type=file> element does not by default work with the ng-model directive. It needs a custom directive:
select-ng-files Directive that Works with ng-model1angular.module("app",[]);
angular.module("app").directive("selectNgFiles", function() {
return {
require: "ngModel",
link: function postLink(scope,elem,attrs,ngModel) {
elem.on("change", function(e) {
var files = elem[0].files;
ngModel.$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>$http.post from a FileList$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.
Use the onchange event to pass the input file element to your function.
<input type="file" onchange="angular.element(this).scope().fileSelected(this)" />
So when a user selects a file, you have a reference to it without the user needing to click an "Add" or "Upload" button.
$scope.fileSelected = function (element) {
var myFileSelected = element.files[0];
};
Easy with a directive
Html:
<input type="file" file-upload multiple/>
JS:
app.directive('fileUpload', function () {
return {
scope: true, //create a new scope
link: function (scope, el, attrs) {
el.bind('change', function (event) {
var files = event.target.files;
//iterate files since 'multiple' may be specified on the element
for (var i = 0;i<files.length;i++) {
//emit event upward
scope.$emit("fileSelected", { file: files[i] });
}
});
}
};
In the directive we ensure a new scope is created and then listen for changes made to the file input element. When changes are detected with emit an event to all ancestor scopes (upward) with the file object as a parameter.
In your controller:
$scope.files = [];
//listen for the file selected event
$scope.$on("fileSelected", function (event, args) {
$scope.$apply(function () {
//add the file object to the scope's files collection
$scope.files.push(args.file);
});
});
Then in your ajax call:
data: { model: $scope.model, files: $scope.files }
http://shazwazza.com/post/uploading-files-and-json-data-in-the-same-request-with-angular-js/
Above accepted answer is not browser compatible. If some one has compatibility issue try this.
View Code
<div ng-controller="MyCtrl">
<input type="file" id="file" name="file"/>
<br>
<button ng-click="add()">Add</button>
<p>{{data}}</p>
</div>
Controller code
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.data = 'none';
$scope.add = function(){
var f = document.getElementById('file').files[0],
r = new FileReader();
r.onloadend = function(e){
var binary = "";
var bytes = new Uint8Array(e.target.result);
var length = bytes.byteLength;
for (var i = 0; i < length; i++)
{
binary += String.fromCharCode(bytes[i]);
}
$scope.data = (binary).toString();
alert($scope.data);
}
r.readAsArrayBuffer(f);
}
}
I am able to upload files using AngularJS by using below code:
The file for the argument that needs to be passed for the function ngUploadFileUpload is $scope.file as per your question.
The key point here is to use transformRequest: []. This will prevent $http with messing with the contents of the file.
function getFileBuffer(file) {
var deferred = new $q.defer();
var reader = new FileReader();
reader.onloadend = function (e) {
deferred.resolve(e.target.result);
}
reader.onerror = function (e) {
deferred.reject(e.target.error);
}
reader.readAsArrayBuffer(file);
return deferred.promise;
}
function ngUploadFileUpload(endPointUrl, file) {
var deferred = new $q.defer();
getFileBuffer(file).then(function (arrayBuffer) {
$http({
method: 'POST',
url: endPointUrl,
headers: {
"accept": "application/json;odata=verbose",
'X-RequestDigest': spContext.securityValidation,
"content-length": arrayBuffer.byteLength
},
data: arrayBuffer,
transformRequest: []
}).then(function (data) {
deferred.resolve(data);
}, function (error) {
deferred.reject(error);
console.error("Error", error)
});
}, function (error) {
console.error("Error", error)
});
return deferred.promise;
}
The code will helps to insert file
<body ng-app = "myApp">
<form ng-controller="insert_Ctrl" method="post" action="" name="myForm" enctype="multipart/form-data" novalidate>
<div>
<p><input type="file" ng-model="myFile" class="form-control" onchange="angular.element(this).scope().uploadedFile(this)">

We have used HTML, CSS and AngularJS. Following example shows about how to upload the file using AngularJS.
<html>
<head>
<script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
</head>
<body ng-app = "myApp">
<div ng-controller = "myCtrl">
<input type = "file" file-model = "myFile"/>
<button ng-click = "uploadFile()">upload me</button>
</div>
<script>
var myApp = angular.module('myApp', []);
myApp.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};
}]);
myApp.service('fileUpload', ['$http', function ($http) {
this.uploadFileToUrl = function(file, uploadUrl){
var fd = new FormData();
fd.append('file', file);
$http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
})
.error(function(){
});
}
}]);
myApp.controller('myCtrl', ['$scope', 'fileUpload', function($scope, fileUpload){
$scope.uploadFile = function(){
var file = $scope.myFile;
console.log('file is ' );
console.dir(file);
var uploadUrl = "/fileUpload";
fileUpload.uploadFileToUrl(file, uploadUrl);
};
}]);
</script>
</body>
</html>
You may consider IaaS for file upload, such as Uploadcare. There is an Angular package for it: https://github.com/uploadcare/angular-uploadcare
Technically it's implemented as a directive, providing different options for uploading, and manipulations for uploaded images within the widget:
<uploadcare-widget
ng-model="object.image.info.uuid"
data-public-key="YOURKEYHERE"
data-locale="en"
data-tabs="file url"
data-images-only="true"
data-path-value="true"
data-preview-step="true"
data-clearable="true"
data-multiple="false"
data-crop="400:200"
on-upload-complete="onUCUploadComplete(info)"
on-widget-ready="onUCWidgetReady(widget)"
value="{{ object.image.info.cdnUrl }}"
/>
More configuration options to play with: https://uploadcare.com/widget/configure/
The easiest is to use HTML5 API, namely FileReader
HTML is pretty straightforward:
<input type="file" id="file" name="file"/>
<button ng-click="add()">Add</button>
In your controller define 'add' method:
$scope.add = function() {
var f = document.getElementById('file').files[0],
r = new FileReader();
r.onloadend = function(e) {
var data = e.target.result;
//send your binary data via $http or $resource or do anything else with it
}
r.readAsBinaryString(f);
}

in simple words
in Html - add below code only
<form name="upload" class="form" data-ng-submit="addFile()">
<input type="file" name="file" multiple
onchange="angular.element(this).scope().uploadedFile(this)" />
<button type="submit">Upload </button>
</form>
in the controller - This function is called when you click "upload file button". it will upload the file. you can console it.
$scope.uploadedFile = function(element) {
$scope.$apply(function($scope) {
$scope.files = element.files;
});
}
add more in controllers - below code add into the function . This function is called when you click on button which is used "hitting the api (POST)". it will send file(which uploaded) and form-data to the backend .
var url = httpURL + "/reporttojson"
var files=$scope.files;
for ( var i = 0; i < files.length; i++)
{
var fd = new FormData();
angular.forEach(files,function(file){
fd.append('file',file);
});
var data ={
msg : message,
sub : sub,
sendMail: sendMail,
selectUsersAcknowledge:false
};
fd.append("data", JSON.stringify(data));
$http.post(url, fd, {
withCredentials : false,
headers : {
'Content-Type' : undefined
},
transformRequest : angular.identity
}).success(function(data)
{
toastr.success("Notification sent successfully","",{timeOut: 2000});
$scope.removereport()
$timeout(function() {
location.reload();
}, 1000);
}).error(function(data)
{
toastr.success("Error in Sending Notification","",{timeOut: 2000});
$scope.removereport()
});
}
in this case .. i added below code as form data
var data ={
msg : message,
sub : sub,
sendMail: sendMail,
selectUsersAcknowledge:false
};

Lightweight Angular JS directive to upload files.
Here is the DEMO page.Features
I've read all the thread and the HTML5 API solution looked the best. But it changes my binary files, corrupting them in a manner I've not investigated. The solution that worked perfectly for me was :
HTML :
<input type="file" id="msds" ng-model="msds" name="msds"/>
<button ng-click="msds_update()">
Upload
</button>
JS:
msds_update = function() {
var f = document.getElementById('msds').files[0],
r = new FileReader();
r.onloadend = function(e) {
var data = e.target.result;
console.log(data);
var fd = new FormData();
fd.append('file', data);
fd.append('file_name', f.name);
$http.post('server_handler.php', fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
console.log('success');
})
.error(function(){
console.log('error');
});
};
r.readAsDataURL(f);
}
Server side (PHP):
$file_content = $_POST['file'];
$file_content = substr($file_content,
strlen('data:text/plain;base64,'));
$file_content = base64_decode($file_content);
UPLOAD FILES
<input type="file" name="resume" onchange="angular.element(this).scope().uploadResume()" ng-model="fileupload" id="resume" />
$scope.uploadResume = function () {
var f = document.getElementById('resume').files[0];
$scope.selectedResumeName = f.name;
$scope.selectedResumeType = f.type;
r = new FileReader();
r.onloadend = function (e) {
$scope.data = e.target.result;
}
r.readAsDataURL(f);
};
DOWNLOAD FILES:
<a href="{{applicant.resume}}" download> download resume</a>
var app = angular.module("myApp", []);
app.config(['$compileProvider', function ($compileProvider) {
$compileProvider.aHrefSanitizationWhitelist(/^\s*(https?|local|data|chrome-extension):/);
$compileProvider.imgSrcSanitizationWhitelist(/^\s*(https?|local|data|chrome-extension):/);
}]);
I tried all alternatives that @Anoyz (Correct answer) gives... and the best solution is https://github.com/danialfarid/angular-file-upload
Some Features:
It's work fine for me. You just have to pay attention to instructions.
In server-side i use NodeJs, Express 4 and Multer middleware to manage multipart request.
http://jsfiddle.net/vishalvasani/4hqVu/ works fine in chrome and IE (if you update CSS a little in background-image). This is used for updating progress bar:
scope.progress = Math.round(evt.loaded * 100 / evt.total)
but in FireFox angular's [percent] data is not updated in DOM successfully,although files are uploading successfully.
HTML
<input type="file" id="file" name='file' onchange="angular.element(this).scope().profileimage(this)" />
add 'profileimage()' method to your controller
$scope.profileimage = function(selectimage) {
console.log(selectimage.files[0]);
var selectfile=selectimage.files[0];
r = new FileReader();
r.onloadend = function (e) {
debugger;
var data = e.target.result;
}
r.readAsBinaryString(selectfile);
}
I know this is a late entry but I have created a simple upload directive. Which you can get working in no time!
<input type="file" multiple ng-simple-upload web-api-url="/api/Upload" callback-fn="myCallback" />
ng-simple-upload more on Github with an example using Web API.
This should be an update/comment to @jquery-guru's answer but as I don't have enough rep it will go here. It fixes the errors that are now generated by the code.
https://jsfiddle.net/vzhrqotw/
The change is basically:
FileUploadCtrl.$inject = ['$scope']
function FileUploadCtrl(scope) {
To:
app.controller('FileUploadCtrl', function($scope)
{

You can use a FormData object which is safe and fast:
// Store the file object when input field is changed
$scope.contentChanged = function(event){
if (!event.files.length)
return null;
$scope.content = new FormData();
$scope.content.append('fileUpload', event.files[0]);
$scope.$apply();
}
// Upload the file over HTTP
$scope.upload = function(){
$http({
method: 'POST',
url: '/remote/url',
headers: {'Content-Type': undefined },
data: $scope.content,
}).success(function(response) {
// Uploading complete
console.log('Request finished', response);
});
}
<form id="csv_file_form" ng-submit="submit_import_csv()" method="POST" enctype="multipart/form-data">
<input ng-model='file' type="file"/>
<input type="submit" value='Submit'/>
</form>
In angularJS controller
$scope.submit_import_csv = function(){
var formData = new FormData(document.getElementById("csv_file_form"));
console.log(formData);
$.ajax({
url: "import",
type: 'POST',
data: formData,

Working Example using Simple Directive (ng-file-model):
.directive("ngFileModel", [function () {
return {
$scope: {
ngFileModel: "="
},
link: function ($scope:any, element, attributes) {
element.bind("change", function (changeEvent:any) {
var reader = new FileReader();
reader.onload = function (loadEvent) {
$scope.$apply(function () {
$scope.ngFileModel = {
lastModified: changeEvent.target.files[0].lastModified,
lastModifiedDate: changeEvent.target.files[0].lastModifiedDate,
name: changeEvent.target.files[0].name,
size: changeEvent.target.files[0].size,
type: changeEvent.target.files[0].type,
data: changeEvent.target.files[0]

and use FormData to upload file in your function.
var formData = new FormData();
formData.append("document", $scope.ngFileModel.data)
formData.append("user_id", $scope.userId)

I have faced a small probelm you can check it here: https://github.com/mistralworks/ng-file-model/issues/7
Finally,here's a forked repo: https://github.com/okasha93/ng-file-model/blob/patch-1/ng-file-model.js
This is the modern browser way, without 3rd party libraries. Works on all the latest browsers.
app.directive('myDirective', function (httpPostFactory) {
return {
restrict: 'A',
scope: true,
link: function (scope, element, attr) {
element.bind('change', function () {
var formData = new FormData();
formData.append('file', element[0].files[0]);
httpPostFactory('upload_image.php', formData, function (callback) {
// recieve image name to use in a ng-src
console.log(callback);
});
});
}
};
});
app.factory('httpPostFactory', function ($http) {
return function (file, data, callback) {
$http({
url: file,
method: "POST",
data: data,
headers: {'Content-Type': undefined}
}).success(function (response) {
callback(response);
});
};
});
HTML:
<input data-my-Directive type="file" name="file">
PHP:
if (isset($_FILES['file']) && $_FILES['file']['error'] == 0) {
// uploads image in the folder images
$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = substr(md5(time()), 0, 10) . '.' . end($temp);
move_uploaded_file($_FILES['file']['tmp_name'], 'images/' . $newfilename);
// give callback to your angular code with the image src name
echo json_encode($newfilename);
}
