Hi all,
I am struggling a bit to get a HTML5 FormData object submitting with
Prototype's Ajax.Request().
Because the form data needs to be submitted as multipart/form-data, I need
to set the Content-Type to include the MIME boundary, otherwise the
receiving end can't decode the multipart/form-data content.
I am doing something like this:
var d = new FormData();
d.append('name', $F('name'));
d.append('type', 'blah');
d.append('filecontent', $('file').files[0]);
new Ajax.Request('url', {
method: 'post',
//contentType: 'multipart/form-data', // need MIME boundary
postBody: d,
onSuccess: function(r) { }
});
If I leave out the contentType parameter, then the form gets submitted as
application/x-www-form-urlencoded, but the content is in
multipart/form-data so it is not possible to decode it. If I set the
contentType to multipart/form-data then the recipient complains that the
MIME boundary is missing from the HTTP Content-Type header.
How can I get the contentType set to include the MIME boundary used by the
HTML5 FormData object?
Many thanks,
Adam.
