Not able to access uploaded files in controller

Question

Latest code which helps me in solving my problem

  $scope.uploadedFiles = []; $scope.upload = function(files) { $scope.uploadedFiles = files; angular.forEach(files, function(file) { if (file && !file.$error) { if($scope.uploadedFiles.indexOf(file) == -1) { $scope.uploadedFiles.push(file); } file.upload = Upload.upload({ url: 'uploader', file: file, userId: $scope.user._id }); file.upload.then(function (response) { $timeout(function () { file.result = response.data.id; }); }, function (response) { if (response.status > 0) $scope.errorMsg = response.status + ': ' + response.data; }); file.upload.progress(function (evt) { file.progress = Math.min(100, parseInt(100.0 * evt.loaded / evt.total)); }); } }); console.log($scope.uploadedFiles); } $scope.removeUploadedFile = function(files, idx) { files.splice(idx, 1); console.log($scope.uploadedFiles); $scope.uploadedFiles = files; console.log($scope.uploadedFiles); } 

  .form-group .btn.btn-default.btn-file i.fa.fa-paperclip | Attach Files input(type='file', ngf-select='upload($files)',accept="text/plain, image/*", ng-model="files", ngf-multiple="true", ngf-max-size='10000000', ngf-keep="true", ngf-keep-distinct="true") p.help-block Max. 1MB br ul#files(ng-repeat="f in files", style='list-style-type: none; padding:0; margin:0;') li div {{f.name}} .pull-right {{f.size | bytes}}   #[i.fa.fa-close(ng-click="removeUploadedFile(files, $index)")] div.progress(ng-show="f.progress >= 0") div(style="width:{{f.progress}}%", ng-bind="f.progress + '%'") 

I'm using ng-file-upload for handling of file uploads. Everything is working fine except that I'm not able to access files in my controller.

Here is my controller code:

$scope.upload = function(files) {
    uploadedFiles = files;
    console.log($scope.files);
    angular.forEach(files, function(file) {
        if (file && !file.$error) {
            file.upload = Upload.upload({
              url: 'uploader',
              file: file,
              userId: $scope.user._id
            });

            file.upload.then(function (response) {
              $timeout(function () {
                file.result = response.data.id;
              });
            }, function (response) {
              if (response.status > 0)
                $scope.errorMsg = response.status + ': ' + response.data;
            });

            file.upload.progress(function (evt) {
              file.progress = Math.min(100, parseInt(100.0 * evt.loaded / evt.total));
            });
      }   
    });

    console.log(uploadedFiles);
}

$scope.removeUploadedFile = function(files, idx) {
  console.log(files);
  files.splice(idx, 1);
  uploadedFiles = files;
}

And my html code:

                                .form-group
                                    .btn.btn-default.btn-file
                                        i.fa.fa-paperclip
                                        |  Attach Files
                                        input(type='file', name='attachment', ngf-select='upload($files)',accept="text/plain, image/*", ng-model="files", ngf-multiple="true", ngf-max-size='10000000', ngf-keep="true", ngf-keep-distinct="true")
                                    p.help-block Max. 1MB
                                    br
                                    //- ul(ng-repeat='file in uploadedFiles', style='list-style-type: none; padding:0; margin:0;')
                                    ul#files(ng-repeat='f in files', style='list-style-type: none; padding:0; margin:0;')
                                        li
                                            div
                                                {{f.name}}
                                                .pull-right
                                                    {{f.size | bytes}}   #[i.fa.fa-close(ng-click="removeUploadedFile(files, $index)")]
                                            div.progress(ng-show="f.progress >= 0")
                                                div(style="width:{{f.progress}}%", ng-bind="f.progress + '%'") 

If I print $scope.files , it prints nothing.

Any pointers where am I doing wrong will be appreciated.

Update:

Why do I need to access $scope.files ? File upload functionalty is working fine but I need to pass uploaded files id to my backend systems for saving that id in my db. Now to do that I need some $scope variable which contains updated list of files. Since I'm allowing the user to delete the uploaded file, I need some $scope variable to be updated with the latest list of valid uploaded files. Let me know if it's still unclear.

There was some issues with ngf-keep which is fixed in version 7.0.12. Your original post should work now or you can follow this: https://jsfiddle.net/danialfarid/e7x1xs4a/

<button ngf-select="uploadFiles($files)" ngf-keep="true" multiple>Select Files</button>

$scope.uploadFiles = function(files) {
    $scope.files = files;
    console.log(files);
    angular.forEach(files, function(file) {
        if (file && !file.$error) {
            file.upload = Upload.upload({
              url: 'https://angular-file-upload-cors-srv.appspot.com/upload',
              file: file
            });

            file.upload.then(function (response) {"success"
            }, function (response) {"error"});

            file.upload.progress(function (evt) {"progress"});
        }   
    });
}

I guess ng-file-upload updates the scope value after calling ngf-select function.

Althought I don't understand why you want to access $scope.files in your updload function even though you can access the same value via function parameter. If you insist to use $scope.files , you could wrap your logic by $timeout.

The sample code is like below.

$scope.upload = function(){
    console.log('Outside $timeout :', $scope.files);
    $timeout(function(){
        console.log('Inside $timeout :', $scope.files);
    });
}

jsfiddle is here.

My suggestion:

1. When you need to access files in ngf-select function, I recommend to use simply the function parameter.

2. When you want to access files in other function, you can simply access $scope.files .

If you want to update files every time you add a new file, you need to set $scope.files outside the function scope and push new file in $scope.files array $scope.files.push(file); :

$scope.files = [];

function uploadFiles(files) {
    angular.forEach(files, function (file) {
        $scope.files.push(file);

        if (file && !file.$error) {
            file.upload = Upload.upload({
              url: 'https://angular-file-upload-cors-srv.appspot.com/upload',
              file: file
            });

            file.upload.then(function (response) {
              $timeout(function () {
                file.result = response.data;
              });
            }, function (response) {
              if (response.status > 0)
                $scope.errorMsg = response.status + ': ' + response.data;
            });

            file.upload.progress(function (evt) {
              file.progress = Math.min(100, parseInt(100.0 * 
                                       evt.loaded / evt.total));
            });
        }   
    });
