ng-model The model value volition be a single file instead of an assortment if all of the followings are true:

ngf-multiple is not set or is resolved to imitation.
multiple aspect is not set on the element
ngf-keep is not set or is resolved to false.

validation When any of the validation directives specified the form validation volition take place and you can access the value of the validation using myForm.myFileInputName.$error.<validate mistake proper name> for example form.file.$error.pattern. If multiple file selection is allowed y'all tin can specify ngf-model-invalid="invalidFiles" to assing the invalid files to a model and find the fault of each individual file with file.$error and clarification of it with file.$errorParam. You can use angular ngf-model-options to allow invalid files to exist set to the ng-model ngf-model-options="{allowInvalid: true}".

Upload multiple files: Only for HTML5 FormData browsers (not IE8-9) you take an array of files or more than than 1 file in your data to ship them all in one request . Non-html5 browsers due to flash limitation will upload each file one past i in a separate request. You should iterate over the files and ship them one by i for a cross browser solution.

drag and drop styling: For file drag and drop, ngf-drag-over-class could be used to manner the drop zone. It can be a function that returns a class proper name based on the $upshot. Default is "dragover" string. Only in chrome It could be a json object {have: 'a', 'reject': 'r', pattern: 'image/*', delay: ten} that specify the class name for the accepted or rejected drag overs. The pattern specified or ngf-blueprint will be used to validate the file'due south mime-type since that is the only property of the file that is reported past the browser on drag. So you cannot validate the file proper name/extension, size or other validations on drag. At that place is as well some limitation on some file types which are non reported by Chrome. delay default is 100, and is used to fix css3 transition problems from dragging over/out/over #277.

Upload.setDefaults(): If yous have many file selects or drops y'all can set the default values for the directives past calling Upload.setDefaults(options). options would be a json object with directive names in camelcase and their default values.

Resumable Uploads: The plugin supports resumable uploads for large files. On your server you need to keep rail of what files are existence uploaded and how much of the file is uploaded.

url upload endpoint demand to reassemble the file chunks past appending uploading content to the end of the file or correct chunk position if it already exists.
resumeSizeUrl server endpoint to render uploaded file size so far on the server to be able to resume the upload from where information technology is ended. It should render nada if the file has not been uploaded all the same.
A Go request volition be made to that url for each upload to determine if part of the file is already uploaded or not. You demand a unique way of identifying the file on the server and then yous tin can pass the file name or generated id for the file as a request parameter.
By default it volition assume that the response content is an integer or a json object with size integer property. If yous return other formats from the endpoint you lot can specify resumeSizeResponseReader function to return the size value from the response. Alternatively instead of resumeSizeUrl you tin use resumeSize function which returns a promise that resolves to the size of the uploaded file so far. Make sure when the file is fully uploaded without whatsoever mistake/arrest this endpoint returns zero for the file size if you want to allow the user to upload the same file again. Or optionally you could take a restart endpoint to set that back to zero to permit re-uploading the aforementioned file.
resumeChunkSize optionally y'all can specify this to upload the file in chunks to the server. This will permit uploading to GAE or other servers that have file size limitation and trying to upload the whole request before passing it for internal processing.
If this choice is gear up the requests volition have the following extra fields: _chunkSize, _currentChunkSize, _chunkNumber (nada starting), and _totalSize to help the server to write the uploaded chunk to the right position. Uploading in chunks could slow down the overall upload time specially if the chunk size is besides minor. When y'all provide resumeChunkSize option ane of the resumeSizeUrl or resumeSize is mandatory to know how much of the file is uploaded and then far.

Quondam browsers

For browsers not supporting HTML5 FormData (IE8, IE9, ...) FileAPI module is used. Note: You need Flash installed on your browser since FileAPI uses Flash to upload files.

These two files FileAPI.min.js, FileAPI.wink.swf volition be loaded past the module on demand (no need to be included in the html) if the browser does not supports HTML5 FormData to avoid extra load for HTML5 browsers. You can place these two files beside angular-file-upload-shim(.min).js on your server to be loaded automatically from the same path or you lot can specify the path to those files if they are in a different path using the post-obit script:

< script >

FileAPI = {

jsPath : ' /js/FileAPI.min.js/folder/ ' ,

jsUrl : ' yourcdn.com/js/FileAPI.min.js ' ,

staticPath : ' /flash/FileAPI.flash.swf/folder/ ' ,

flashUrl : ' yourcdn.com/js/FileAPI.flash.swf ' ,

}

</ script >

< script src = " athwart-file-upload-shim.min.js " > < / script > ...

Old browsers known bug:

Because of a Wink limitation/problems if the server doesn't send whatever response trunk the status code of the response volition be ever 204 'No Content'. Then if yous accept access to your server upload code at to the lowest degree return a character in the response for the status code to work properly.
Custom headers will not work due to a Wink limitation #111 #224 #129
Due to Flash bug #92 Server HTTP fault code 400 volition be returned equally 200 to the client. So avoid returning 400 on your server side for upload response otherwise it will exist treated as a success response on the client side.
In case of an error response (http code >= 400) the custom error message returned from the server may not be bachelor. For some mistake codes flash just provide a generic error message and ignores the response text. #310
Older browsers won't permit PUT requests. #261

CORS

To back up CORS upload your server needs to allow cross domain requests. You tin can achieve that by having a filter or interceptor on your upload file server to add CORS headers to the response similar to this: (sample java code)

httpResp . setHeader ( " Admission-Control-Let-Methods " , " POST, PUT, OPTIONS " ) ;

httpResp . setHeader ( " Access-Control-Allow-Origin " , " your.other.server.com " ) ;

httpResp . setHeader ( " Access-Command-Allow-Headers " , " Content-Type " ) ) ;

For non-HTML5 IE8-9 browsers you would also need a crossdomain.xml file at the root of your server to let CORS for flash: (sample xml)

< cross-domain-policy >

< site-command permitted-cross-domain-policies = " all " />

< permit-access-from domain = " athwart-file-upload.appspot.com " />

< permit-http-request-headers-from domain = " * " headers = " * " secure = " false " />

</ cross-domain-policy >

Amazon AWS S3 Upload

For Amazon hallmark version iv run across this comment

The demo page has an option to upload to S3. Hither is a sample config options:

Upload . upload ( {

url : ' https://angular-file-upload.s3.amazonaws.com/ ' ,

method : ' Mail ' ,

data : {

key : file . name ,

AWSAccessKeyId : < YOUR AWS AccessKey Id > ,

acl : ' private ' ,

policy : $telescopic . policy ,

signature : $telescopic . signature ,

" Content-Type " : file . blazon != ' ' ? file . type : ' awarding/octet-stream ' ,

filename : file . proper noun ,

file : file

}

} ) ;

This commodity explains more about these fields and provides instructions on how to generate the policy and signature using a server side tool. These two values are generated from the json policy document which looks similar this:

{

" expiration " : " 2020-01-01T00:00:00Z " ,

" weather " : [

{ " saucepan " : " angular-file-upload " } ,

[ " starts-with " , " $key " , " " ] ,

{ " acl " : " individual " } ,

[ " starts-with " , " $Content-Type " , " " ] ,

[ " starts-with " , " $filename " , " " ] ,

[ " content-length-range " , 0 , 524288000 ]

]

}

The demo page provide a helper tool to generate the policy and signature from you from the json policy document. Note: Delight use https protocol to admission demo page if you are using this tool to generate signature and policy to protect your aws secret central which should never be shared.

Make sure that y'all provide upload and CORS postal service to your bucket at AWS -> S3 -> bucket name -> Properties -> Edit bucket policy and Edit CORS Configuration. Samples of these 2 files:
