Getting uploadify to work

[eluser]Bramme[/eluser]
Hi guys

I'm working on a little project and I need to upload several files for an image gallery. Instead of uploading all files seperately, I've decided to use some sort of multi-uploader.

I've found this great jQuery plugin: Uploadify

Here's the code I use:

The form

Code:

<?php echo form_open_multipart($this->uri->uri_string); ?>
<p><label for="title">Title: <br />
&lt;input type="text" name="title" id="title" /&gt;
</label></p>
<p>Select the photos you would like to add to the gallery<br />
&lt;input type="file" name="file_input" id="file_input" /&gt;
</p>

&lt;/form&gt;

The JS that loads Uploadify:

Code:

$(document).ready(function() {
    $('#file_input').fileUpload({
        'uploader': '/svn/handinhand/assets/js/uploadify/uploader.swf',
        'script': '/svn/handinhand/admin/gallery/upload',
        'folder': '/svn/handinhand/assets/images/galleries',
        'multi': true,
        'auto': true,
        'fileExt': '*.jpg;*.jpeg;*.png;*.gif',
        'buttonText': 'Browse...',
        'cancelImg': '/svn/handinhand/assets/js/uploadify/cancel.png'
    });
});

My upload function:

Code:

function upload() {
    if ( ! empty($_FILES)) {
        $tempFile = $_FILES['file_input']['tmp_name'];
        $targetPath = $_SERVER['DOCUMENT_ROOT'] . '/SVN/handinhand/assets/images/galleries';
        $targetFile =  str_replace('//','/',$targetPath) . $_FILES['file_input']['name'];
        
        move_uploaded_file($tempFile,$targetFile);
    
    }
    
    echo '1';
}

As far as I can tell Uploadify is loading, I can click on the button, I can select multiple files and when I select them, they are loaded in my uploading queu. However, they immediately return "IO Error - picturename - 100%" and the files aren't uploaded.

Have any of you worked with this plugin before or have any clue as to how to get it working?
