Hi

The ezbinaryfile has support for detecting if file is bigger than upload_max_file_size. However, ezbinaryfile doesn't detect if file size exceeds post_max_size.
This is not possible to detect by a datatype either since all post variables are removed in such case. It therefore needs to be detected elsewhere (like in content/edit)

Here is a patch which does the trick.

Regarding my comment:

if( ( (int) $_SERVER['CONTENT_LENGTH'] > $postMaxSize ) &&  // This is not 100% accurate as $_SERVER['CONTENT_LENGTH'] doesn't only count post data but also other things

In PHP's source code you have this (main/rfc1867.c):

if (SG(request_info).content_length > SG(post_max_size)) {
                sapi_module.sapi_error(E_WARNING, "POST Content-Length of %ld bytes exceeds the limit of %ld bytes", SG(request_info).content_length, SG(post_max_size));
                return;
        }

I guess SG(request_info).content_length is the size of the whole request, not only the post data. But I am not sure...Anyway, since we also check if we indeed has no POST variables I think the detection in my patch is quite OK.
