After scouring the forums, both the Silverstripe and Uploadify; I wasn't sure which to specifically diagnose.

Using the latest Silverstripe (2.4.5), latest DataObjectManager and Uploadify (since 4/1/2011):

In attempts to upload anything, I end up with a white page, except for "Closing..."

With the following notable firefox error console errors:

Error: parent.jQuery is not a function

Warning: Form contains a file input, but is missing method=POST and enctype=multipart/form-data on the form.  The file will not be sent.

Interestingly enough, it seems to have uploaded the files... despite the nearly-White-Screen-Of-Death. My local WAMP version, wasn't able to get that far. I've worked with DataObjectManager and Uploadify with success in the past, so as far as I know it isn't blatant user error.

Thoughts?

Yeah, it looks like the Form class is hardcoded to look for FileField subclasses. That's a drag. No way to override it, either.

function FormEncType() {
if(is_array($this->fields->dataFields())){
foreach($this->fields->dataFields() as $field) {
if(is_a($field, "FileField")) return "multipart/form-data";
}
}
return "application/x-www-form-urlencoded";
}

I appreciate the reply,

..but where specifically are you pulling this snippet from? Silverstripe Core? Uploadify? DataObjectManager? ... and the fact that there "no way to override it", no band-aids? Because in working with different site, this time utilizing your Image_Gallery.

Same error, I feel like I must be missing something.

Thanks,

That's in Form.php.

It's not really an error, it's just a warning. Ideally you want the multipart enctype on a form with a file input, but it's kind of a moot point since Flash replaces the file input with its own interface.
