Multiple File Upload
This article deals with multiple file upload using SWF upload,A tool for multiple image uploads
SWF is a Java script Library that uses the Flash Player's upload function which includes file size checking and uploading progress
The file upload can be done by using the following java script code as follows
var swfu;
function fnUpload() {
swfu = new SWFUpload({
// Backend Settings
upload_url: "uploadMultipleImages.aspx?QuStr=photos",
post_params: {
"QuStr": "photos"
},
// File Upload Settings
file_size_limit: "10 MB",
file_types: "*.jpg;*.gif;*.bmp;*.jpeg",
file_types_description: "JPG Images",
file_upload_limit: "0", // Zero means unlimited
// Event Handler Settings - these functions as defined in Handlers.js
// The handlers are not part of SWFUpload but are part of my website and control how
// my website reacts to the SWFUpload events.
file_queue_error_handler: fileQueueError,
file_dialog_complete_handler: fileDialogComplete,
upload_progress_handler: uploadProgress,

button_text_left_padding: 5,
// Flash Settings
flash_url: "photos/swfupload/swfupload.swf", // Relative to this file
custom_settings: {

},
// Debug Settings

});
}
Handler
This javascript file handles the displaying of uploaded images and displaying the upload progress removal of images etc
The Image upload as follows, the file uploadMultipleImages.aspx?QuStr=photos is referred for uploading the images and this file is responsible
for creating three sets of files ranging from small,large,thumbnail and the actual size of the image

Upload Success
This function gets triggered after successive upload and it is as follows
function uploadSuccess(file, serverData) {
try {
var vid = $(file).attr('id');
addImage(serverData,vid);
var progress = new FileProgress(file, this.customSettings.upload_target);
progress.setStatus("Thumbnail Created.");
progress.toggleCancel(false);
} catch (ex) {
this.debug(ex);
}
}
function uploadComplete(file) {
try {
/* I want the next upload to continue automatically so I'll call startUpload here */
if (this.getStats().files_queued > 0) {
this.startUpload();
} else {
var progress = new FileProgress(file, this.customSettings.upload_target);
progress.setComplete();
progress.setStatus("All images received.");
progress.toggleCancel(false);
}
} catch (ex) {
this.debug(ex);
}
}
function addImage(src,vid) {
var newDiv = document.createElement("div");
newDiv.setAttribute("class", "divStyle");
var newImg = document.createElement("img");
newImg.style.margin = "5px";
newImg.id = 'img' + vid;
newDiv.appendChild(newImg);
document.getElementById("thumbnails").appendChild(newDiv);
newImg.onload = function () {
fadeIn(newImg, 0);
};
newImg.src = src;
var divHtml = 'Remove';
$('#img' + vid).after(divHtml);
$('#divProgress').show();
}
In the method addImage a div,img and anchor tags were created which is then binded to the parent div-thumbnails this function in short is used to display the
recently uploaded images.
Remove the uploaded Image
This is done to remove the uploaded images and it is as follows
function deleteImage(vid) {
var imgsrc = $('#img' + vid).attr('src');
var lnkId = $('#img' + vid).attr('id');
var imgId = $('#lnk' + vid).attr('id');
$.ajax({
type: 'Post',
url: 'uploadMultipleImages.aspx?QuStr=removephoto&photosrc=' + imgsrc,
dataType: "json",
data: null,
success: function (data) {
removephotosSucess(data);
}
});
$('#' + lnkId).remove();
$('#' + imgId).remove();
$('#divProgress').hide();
}
after the successful ajax call is made the file gets the following function is referred and it is as follows,
public void RemovePhoto()
{
try
{
//string FileName = Path.GetFileName("uploadedfiles/small/photos-2012-9-6-12-32-17.jpg").ToString();
