Question

When using Uploadify, you specify a folder for the image (eg ‘folder’ : ‘/uploads’), however in the controller action of an MVC app the image is also being saved!

Im confused – is it Uplodify or the controller action that saves the image?

LillyPop – Uploadify sends the filestream via ajax to the controller action, so it’s the controller action (or service class called by the action) that does the heavy lifting. you’ll typically see something like this in your javascript method:

<script type="text/javascript">
    function initupLoadify() {
        $("#fileInput").uploadify({
            uploader: '<%=Url.Content("~/scripts/swf/uploadify.swf")%>',
            script: '<%=Url.Content("~/en/PropertyDocument/Upload/")%>',
            cancelImg: '<%=Url.Content("~/Content/cancel.png") %>',
            auto: true,
            sizeLimit: 5500000,
            fileDataName: 'fileData',
            scriptData: { 'propertyId': $("#PropertyID").val() },
            buttonText: 'Add Document',
            onComplete: function(event, queueID, fileObj, response) {
                $("#msg").html(response);
                return true;
            },
            onCancel: function(evt, queueID, fileObj, data) {
                $("#msg").html("<br />Operation cancelled");
                return true;
            },
            onOpen: function(evt, queueID, fileObj) {
                $("#msg").html("<br />Upload in progress");
                return true;
            },
            onError: function(event, queueID, fileObj, errorObj) {
                $("#msg").html(fileObj.name + " was not uploaded ");
                if (errorObj.status == 404)
                    $("#msg").html("Could not find upload script. Use a path relative to: " + "<?= getcwd() ?>");
                else if (errorObj.type === "HTTP")
                    $("#msg").html("error " + errorObj.type + ": " + errorObj.status);
                else if (errorObj.type === "File Size")
                    $("#msg").html(fileObj.name + " " + errorObj.type + " Limit: " + errorObj.info / 1000 + " KB");
                else
                    $("#msg").html("error " + errorObj.type + ": " + errorObj.text);
            }
        });
    };
</script>

the section script: '<%=Url.Content("~/en/PropertyDocument/Upload/")%>' is where the controller action is defined.
