Uploading multiple files asynchronously by blueimp jquery-fileupload
Solved.
Fiddle: http://jsfiddle.net/BAQtG/29/
And js code
$(document).ready(function(){
var filesList = [],
paramNames = [],
elem = $("form");
file_upload = elem.fileupload({
formData:{extra:1},
autoUpload: false,
fileInput: $("input:file"),
}).on("fileuploadadd", function(e, data){
filesList.push(data.files[0]);
paramNames.push(e.delegatedEvent.target.name);
});
$("button").click(function(e){
e.preventDefault();
file_upload.fileupload('send', {files:filesList, paramName: paramNames});
})
})
