Setup

How to setup the plugin on your website

1. Download the plugin archive, extract it and upload the contents (without the "example" directory) to your server.
2. Add the following two lines to the head of your page (adjust the path to the jquery.fileupload-ui.css file):

<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.11/themes/base/jquery-ui.css" id="theme">
<link rel="stylesheet" href="../jquery.fileupload-ui.css">

3. Add the following form to the body of your page (replace upload.php with the path to your upload handler):

<form id="file_upload" action="upload.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="file" multiple>
    <button>Upload</button>
    <div class="js">Upload files</div>
</form>

4. Add the following line to the body of your page, where you want the upload/download table to appear:

<table id="files"></table>

5. Add the following lines to the bottom of your page, before the closing body tag (adjust the paths to the jquery.fileupload.js and jquery.fileupload-ui.js files):

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.11/jquery-ui.min.js"></script>
<script src="../jquery.fileupload.js"></script>
<script src="../jquery.fileupload-ui.js"></script>
<script>
/*global $ */
$(function () {
    $('#file_upload').fileUploadUI({
        uploadTable: $('#files'),
        buildUploadRow: function (files, index) {
            return $('<tr><td>' + files[index].name + '<\/td>' +
                    '<td class="file_upload_progress"><div><\/div><\/td>' +
                    '<td class="file_upload_cancel">' +
                    '<button class="ui-state-default ui-corner-all" title="Cancel">' +
                    '<span class="ui-icon ui-icon-cancel">Cancel<\/span>' +
                    '<\/button><\/td><\/tr>');
        },
        buildDownloadRow: function (file) {
            return $('<tr><td>' + file.name + '<\/td><\/tr>');
        }
    });
});
</script> 

6. Implement your server-side file upload handler to store the uploaded files and return a JSON response with the file information, e.g.:

{"name":"picture.jpg","type":"image/jpeg","size":"123456789"}

Note: The file upload plugin makes use of iframes for browsers like Microsoft Internet Explorer and Opera, which do not yet support XMLHTTPRequest uploads.
They will only register a load event if the Content-type of the response is set to text/plain or text/html, not if it is set to application/json.
