In PHP, I am able to access the name attribute of multiple files submitted through forms at the server side in $_FILES global.

For example, a file input with name="picture[]" will allow me to upload multiples files with the same attribute name. This can be access in PHP as;

 $files =  $_FILES["picture"]; // This filter out only files with a name attribute of "picture[]"

foreach ($files as $file) {
    $filename = $file["name"];
    ...
}



Now I wanted to implement this in D (vibe.d) and here is what I did in the file upload handler.

void upload(HTTPServerRequest req, HTTPServerResponse res)
{
    import std.stdio;

    foreach(picture; req.files) // req.files includes all uploaded files
    {
        ...
    }	
}
However, I want to filter out only those files with attribute name of "picture[]" from req.files.  I tried req.files.name == "picture[]" and other combination but there seem to be no property like that (How do I print all properties of req.files by the way? :) ).

Any help on this?

iterate over req.files like this instead:

foreach (name, picture; req.files) // name is "picture[]" now
{
    ...
}

pragma(msg, __traits(allMembers, typeof(picture)));

Nice.

Wow. I have a lot to learn :). PHP had spoon-fed me.
