More importantly - post the entire form fragment when discussing problems with input elements. On MDN enctype="multipart/form-data" kind of sticks out like a sore thumb - but I figured that you had that covered given you got the PHP version working.
Aside: Does anybody have any information on the origin of the “[]” name suffix convention for multiple files? It seems that the HTML specification doesn’t require it but it seems to be more of a server-side convention (PHP specifically). Or am I wrong about this?
