file upload with scriptaculous and code igniter?

[eluser]edwardmolasses[/eluser]
hi everyone,

I was wondering if anyone was able to do file uploads with code igniter and scriptaculous?

I have the following scriptaculous/js code that executes when someone clicks the file upload button:

Code:

new Ajax.Updater('addImagesDiv', '<?=site_url()?>/weddings/ajaxAddImage/<?=$this->db_session->userdata('id')?>', {method:'post', asynchronous:true, evalScripts:true, parameters:Form.serialize('f1')});

where f1 is the form name and the file input looks like:

Code:

<input class="inputClass" type="file" name="userfile">

And in my controller ajax function ajaxAddImage, I do the traditional code igniter upload, but it doesn't upload the file and i get the error:

Unable to find a post variable called userfile.

Does anyone have any tips?

thanks,
andrew.

It's not possible to upload file via ajax, the only possibility of background uploading is hidden frame or flash. For flash I could recommend one solution: http://swfupload.mammon.se/

In the past I have used an iframe to upload a files while retaining state on the current page. When the frame reloads I combine it with a bit of ajax to dynamically display/delete the uploaded file on the page. I haven't done this in a while, but I am pretty sure I did it with Prototype and Scriptaculous. I could dig it out for you if you want.

edit: i found the files... PM me if you want them

Thanks a lot for the info, i'm still a bit of an scriptaculous beginner, ack. After your posts and doing a bit of researching, it looks like we might go with a different interface to make it easy on ourselves. Thanks so much for the help though!
