I am upgrading an application that is using nv-file-select directive. I am unsure as to how to restrict the file formats supported for upload.
You want to use the filters as described in the documentation.
Create the filter:
var uploader = $scope.uploader = new FileUploader({
url: '/api/users/photo'
});
// FILTERS
uploader.filters.push({
name: 'imageFilter',
fn: function(item /*{File|FileLikeObject}*/, options) {
var type = '|' + item.type.slice(item.type.lastIndexOf('/') + 1) + '|';
return '|jpg|png|jpeg|bmp|gif|'.indexOf(type) !== -1;
}
});
Docs suggests entering it in the HTML, such as I have done below:
<input type="file" nv-file-select="" uploader="uploader" filters="imageFilter">
This code was used on his sample site that allows for image only uploads.
